Catalysts can act as “power generators”? ZJU-Hangzhou Global Scientific and Technological Innovation Center reveals the secret for you!

2022-02-28

Have you ever thought whether there is a substance in the world that can act as both a catalyst and a “power generator” and can be prepared on a large scale and highly energy-efficient.Yes, there really is! Its name is: biological small molecule complexing agent. Through the R & D of γ-carboxyglutamic acid (Gla) as a biological small molecule complexing agent, Tao Kai, a young PI from Future Science Research Institute of ZJU-Hangzhou Global Scientific and Technological Innovation Center, and his team realized the performance of complexation effect comparable to that of traditional ethylenediaminetetraacetic acid ( EDTA) complexing agent, showing excellent catalytic performance and piezoelectric properties!An Innovative CatalyzerResearcher Tao Kai said that traditional biocatalysis is made possible with biological enzymes, but biological enzymes demand good storage conditions, and it is difficult to prepare biological enzymes on a large scale, and to synthesize artificially. Most of them can only be extracted from living organisms.  However, the biological small molecule complexing agent developed by Tao Kai and his team under the new framework is featured by low cost, simple preparation, and better catalytic performance than traditional biological enzymes.The schematic diagram of the preparation of EDTA-like complex structures by Gla complex metal ions is shown in Figure 1. Similar to traditional EDTA, Gla participates in metal coordination with the carboxyl group on the molecular backbone so as to form a clamp-type chelating superstructural system.Fig.1 Constitutive model of Gla-metal ion complexationFurther studies show the Gla-metal ion complex system can be self-assembled to needle-like crystal structures (Fig. 2). In the assembly, each metal ion and five carboxyl groups of three Glas form complex bonds, thereby a superstructural system with high thermal stability is assembled.  Fig. 2 Mechanism analysis of Gla-metal ion complex assemblyAs copper ions [Cu (II)] play an important catalytic role in the metabolism of living organisms, the research team studied the catalytic performance of Gla+Cu (II) complex system at first and later it was found that Gla+Cu (II) had extremely high catalytic performance on the coupling reaction of 2,4-dichlorophenol (2,4-DP) and 4-aminoantipyrine (4-AP) (Fig. 3). In the presence of Gla+Cu (II) system, the reaction solution reaches an obvious absorption peak at 507 nm, which proves that Gla+Cu (II) shows excellent catalytic performance, so it is expected to replace traditional biological enzyme catalysts.Figure 3. Catalytic performance test of Gla+Cu (II) complex superstructure.Magic “Power Generator” The piezoelectric performance, in some sense, can be understood as the capacity to generate mechanical power.Tao Kai and his team discovered that designing and manufacturing a piezoelectric generator with the Gla+Zn (II) complex system as a pressure-sensitive component, under the action of an applied pressure of 50N, an open-circuit voltage (Voc) of 1.5 ± 0.3 V and a short-circuit current ( Isc) up to a signal output of 138.8 ± 26.5 nA can be realized, and it is equivalent to the power of an AA dry battery.Meanwhile, this structure is also particularly “strong” and can withstand “thousands of trials”. The high mechanical strength of the complex architecture ensures that the piezoelectric generator has high tolerance and can maintain a stable voltage output after 1000 50 N pressure cycling tests (Figure 4).Fig. 4. Piezoelectric generator fabricated by Gla+Zn (II) complex framework.(a) Gla+Zn (II), a pressure-sensitive component in the piezoelectric generator; (b,c) the relationship between device open-circuit voltage (Voc) and short-circuit current (Isc) and load; (d) Piezoelectric generator durability test.There are bright prospects to design and manufacture piezoelectric generators with the Gla+Zn (II) complex system as a pressure-sensitive component because of its excellent piezoelectric properties.Is it wonderful that lead-containing inorganic piezoelectric materials are no longer needed in batteries if this kind of piezoelectric generators is used to make biological batteries? As long as there is some pressure from the outside, biological batteries can generate power, which will be more environment-friendly than traditional batteries, so new horizons can be opened up to help realize carbon neutrality.Meanwhile, this generator can also be applied to sensors. With the use of polypeptide biomaterials, it will be more suitable to be implanted into human body than other materials, so it will play a bigger role in wearable medical equipment to help the R & D of bionic electronic skin and the interactive equipment of bio-device interfaces. Be innovative and pioneer the future “Almost no research project will develop exactly as what we expect. Only by seizing some extraordinary moments can breakthroughs be achieved.” Tao Kai firmly believes that innovations can be achieved with breakthroughs, and innovations often originate from unexpectedness.The discovery of biological small molecule complexing agents achieved unexpected results just because Tao Kai and his team used amino acids to design an EDTA-like clamp-type complexing architecture system, and combined amino acids and metal ions in an innovative way.The complex architecture can be self-assembled to needle-like superstructures so as to significantly boost the activities of complexing metal ions and show excellent catalytic and piezoelectric properties; therefore, it can provide a new way of thinking for the design and manufacturing of multifunctional bio-organic soft devices with bio-organic small molecule complexing superstructures.

Only TWO in the world are selected every FOUR years! Songchao Chen, a young PI from ZJU-Hangzhou Global Scientific and Technological Innovation Center who does “physical examinations” for the soil, won this honor!

2022-02-22

The 2nd “Dan Yaalon Young Scientists Medal” winners were announced lately. Songchao Chen, a young PI from Soil Pollution Control and Remediation Innovation Workshop of the Center, won this honor.   The “Dan Yaalon Young Scientist Medal”, in memory of Dan Yaalon (1924-2014), a prestigious scientist in soil science, is awarded to the young scholars who have obtained their doctorates within the last five years and who have made significant contributions to and have great potential  in the fields of soil geography, soil occurrence, soil classification,  soil morphology and micromorphology, quantitative pedology, paleosol, as well as history of soil science, philosophy and sociology. As the only award by the International Union of Soil Sciences for young scholars, the medal is awarded every four years to a total of two winners.   Songchao Chen, a young PI of the  Center, got his Ph.D from National Research Institute for Agriculture,  Food and Environment, France and Agreenium (the agronomic, veterinary  and forestry institute of France), was granted the “Dan Yaalon Young Scientist Medal” (2022) and the 2019 Best Paper Award in Quantitative Soil Science of the International Union of Soil Sciences. So far he has published over 60 SCI papers, among which he has published more than 10 SCI papers as the first author in Geoderma and other top journals of soil science, and got 1 national invention patent.Dr. Songchao Chen, born in the 1990s, is a young scientist from Soil Pollution Control and Remediation Innovation Workshop of the Center. Why was he awarded this distinguished global honor? What has he achieved so far? The official statement goes like this:Dr. Songchao Chen’s  research is of great significance to large-scale soil quality  monitoring and management, soil ecological service function assessment,  etc., and he has made contributions to the field of soil temporal and spatial evolution.Large-scale  soil quality monitoring and management, soil ecological service  function assessment... What do these high-sounding terms mean? What  meaningful work is Dr. Chen doing? He introduced to us with a smile, “My research, put it bluntly, is doing ‘physical examinations’ of the soil”.  Big Data Modeling Makes Soil “Physical Examinations” AccurateSoil pollution prevention and control is a worldwide research project. Unlike air pollution or water pollution, once pollution occurs, it can be observed immediately; however, soil pollution can only be detected after a period of time, so there is a certain lag. Meanwhile, due to different industries and characteristic pollutants in different regions, it is impossible to generalize soil pollution, so we need to propose targeted solutions to precise prevention and control.Dr. Chen made an analogy that the polluted soil is like a “patient”. How to “cure” the polluted soil? The first thing is to “prescribe targeted medicine”. However, the spatial distribution of soil information was often inaccurate, and usually a large particular area was marked with a certain feature due to technical limitations in the past.  But, is this the truth? Even  soils in different villages or different patches of farmland are  different, let alone in different cities or countries. Therefore it is  significant to make an accurate calculation of these data, analyze the changes of soil quality in time and space sequence, integrate them into the same big data system, and make accurate prediction and analysis. “If we say traditional soil surveys are like taking the pulse in traditional Chinese medicine, only a rough guess is made about the general problems in a large strip of soil. Our research is like the ‘integration of traditional Chinese and Western medicine’, which can make us realize the problems on the surface, and understand the specific location and characteristics of the ‘sick’ soil in detail as CT does,” Dr. Songchao Chen explained.Relying on the empirical judgment of experts, traditional soil survey and mapping technologies show problems of long cycle, high cost, slow updating and low accuracy, as well as inaccurate  monitoring and management of large-scale soil information. In response  to this situation, Dr. Chen proposed a new digital soil mapping  technology. With a hybrid spatial prediction model integrating machine learning and geostatistics, he has made key soil attributes (organic matter and pH) products of national-scale 90-meter spatial resolution for the first time in China.   Dr. Chen also said, “By  mining the correlation between soil sample information and  environmental variables, the accurate representation of soil data from  point to surface, and to  three-dimensional space can be realized, and the spatial distribution  of soil information can be intelligently analyzed in real time,  efficiently and accurately so as to provide strong support for territorial resources surveys, soil quality monitoring and pollution risk assessment.”In addition, Dr. Chen has developed the space fine representation technology of space-ground integrated soil information, discovered more soil-environment  remote sensing big data, coupled geostatistical and machine learning  models, and achieved high-resolution, high-precision digital soil  mapping. Currently being developed by ZJU-Hangzhou Global Scientific and Technological Innovation Center, the technology aims at providing data support for understanding China’s soil resources, assessing the transformation of soil carbon sinks and sources and carbon neutrality under climate change, and promoting China’s soil big data information platform and serving China’s soil environmental management.Accurate Assessment, Dynamic Governance and Digital Soil Constructing Ecological ChinaAccurate monitoring is for accurate and dynamic governance. Dr. Songchao Chen said that soil pollution is caused by many factors, of which human activities have the greatest impact. For example, a patch of land used  to have the soil of good quality when it began to be monitored and  then, a factory with heavy pollution was built there and soil may be  polluted. For another case, for the same land near a factory, there are different pollution levels for the soil with different distances from the factory.  “Making a good soil big data platform is only the first step in soil pollution prevention and control. We also need to monitor and remediate soil dynamically,” Dr. Songchao Chen said, and he will work with other PI and post-doctoral fellows from Soil Pollution Control and Remediation Innovation Workshop of the Center, and make good use of the front-end remote sensing big data monitoring technology, as well as the back-end micro-nano remediation materials, technologies and equipment to form full-process remediation and governance.  Lucid waters and lush mountains are invaluable assets!Before returning to China, Dr. Songchao Chen worked at National Research Institute for Agriculture, Food and Environment, France. He said, compared with European countries and the United States, China still faces severe soil environmental pollution and research gaps in related fields. Therefore, it is imperative to speed up  research and innovation in soil environment in-situ monitoring,  remediation technology, materials and equipment, and environmental  information management so as to work for national pollution prevention and control strategy and promote the commercialization and industrialization of soil pollution prevention and control.  Lucid waters and lush mountains are invaluable assets. Dr. Songchao Chen is happy to find that eco-civilization has been more and more popular in the past few years, and there are great advances in soil pollution prevention and control in China. A series of initiatives have been made. In 2014, China launched the first national survey report on soil pollution; In 2016, China issued the “Soil Pollution Prevention and Control Action Plan” and initiated the Second National Pollution Source Census and Detailed Survey of Soil Pollution; in 2019, the “Soil Pollution Prevention and Control Law of the People’s Republic of China” came into effect. Recently, Third National Soil Census is to be conducted by the State Council. Behind the legislation are the changes of people’s awareness. Dr. Songchao Chen was born in Shaoxing, Zhejiang, a beautiful water town in the area to the south of the Yangtze River. Rapid industrial progress in Shaoxing used to bring a take-off to its economy, but it caused pollution too. However, with right environmental protection, his hometown is showing radiant beauty now, so he is full of confidence in China’s soil pollution control.There is a wide world and a lot to do. Let technology empower eco-civilization and make the land under our feet blossom. This is the original aspiration of Dr. Chen in his endeavors. Soil Pollution Control and Remediation Innovation WorkshopThe  Innovation Workshop was established by the College of Environmental  & Resource Sciences of Zhejiang University, with Academician Lizhong  Zhu of the Chinese Academy of Engineering serving as the Chief  Scientist, to lead the scientific research in the directions relating to  soil environment and ecological remediation. Addressing China’s  major needs in soil pollution control and remediation, the Workshop  will, with the micro-nano manufacturing platform and innovative system  mechanism of the Center, focus on the technological innovation in the  fields of micro-nano process and detection of the soil environment,  environmental micro-nano remediation materials as well as environmental  information management, to drive breakthroughs in industries such as  environmental sensing, soil remediation and big data. The Workshop is  committed to building a domestically leading and world-class soil  environment research innovation platform, talent cultivation base and  think tank, and promoting the in-depth development and integration of  industry, university and research.

Application in Diffuse Electronics and Optoelectronics! 2D Heterostructures were revealed by ZJU-Hangzhou Global Scientific and Technological Innovation Center in Chemical Reviews

2022-02-16

A grand family of two-dimensional (2D) materials and their heterostructures have been widely applied in flexible sensors, photodetectors, high-frequency electronics, solar cells, data storage, low-power neuromorphic computing and ubiquitous electronics for their wide band gap selection, no dangling bonds, excellent mobility at atomic layer thickness, and high light absorption. These pioneering works contribute to realizing the fundamental platforms to explore and analyze new physical/chemical properties and technological phenomena at the micro–nano scales.   Recently, a paper entitled “2D Heterostructures for Ubiquitous Electronics and Optoelectronics: Principles, Opportunities, and Challenges” with the IF 60.6, written by by the research team of YU Bin, XU Yang and the team of DUAN Xiangfeng of the Future Science Research Institute at ZJU-Hangzhou Global Scientific and Technological Innovation Center was published on Chemical Reviews. Chemical Reviews is one of the top academic journals in the field of international chemistry and chemical engineering as well as the most authoritative review journal of American Chemical Society. Its 2020 impact factor released in 2021 was 60.6. With an elaboration of the latest progress in the representation of 2D materials, the review focuses on the great impact of preparation methods, characterization techniques and physical parameters on 2D heterostructures. The main emphasis is on 2D heterostructures and 3D-bulk (3D) hybrid systems exhibiting intrinsic quantum mechanical responses in the optical, valley, and topological states as well as the application and development of 2D heterostructures in future electronics and optoelectronics.Surfaces/Interfaces of 2D Heterostructures and Materials of Different Dimensions 01. Characteristics and challenges of 2D Heterostructures2D heterostructures are eessential to advancing the R&D of future electronics and optoelectronics, as they provide fundamental tools for exploring valleytronics, spintronics, and neuromorphism. However, the instability of the bonds on the surface of van der Waals nanoheterostructures restricts its extensive development and is in need of further in-depth research by researchers. Currently, 2D heterostructures have not yet developed large-scale fabrication and integration technologies that match existing silicon processes. There are still grave challenges in material synthesis, device fabrication, and integration although great progress has been made in the field of electronics for single devices and small circuits based on 2D materials.02. How should 2D heterostructures be put into industry in order to advance semiconductor field?One of the major advantages of CMOS compatibility is that 2D materials without surface dangling bonds can be integrated with any substrate. However, several challenges remain to be addressed, including low-temperature grown van der Waals heterostructures, self-cleaning transfer methods, 2D materials of continuum film deposition, and renewable metal contacts. At present, challenges still exist in the establishment of a separate production line for 2D materials in terms of technology and cost. All in all, the best option for commercializing van der Waals 2D heterostructure devices is to process these materials with existing silicon-based production lines. It is believed that more researchers will explore feasible solutions to integrating 2D materials with existing silicon-based processes so as to put 2D heterostructure device technology into industry sooner, to enhance China’s global competitiveness and impact in the semiconductor field and make due contribution to China’s sci-tech innovation.  “Grow Tree” based on van der Waals 2D heterostructure devicesMore importantly, it is an international co-authored paper.

35 Innovators Under 35! Yiming Mo, a Young PI of ZJU-Hangzhou Global Scientific and Technological Innovation Center, is one of them

2022-01-26

Our life is changed by science and technology and young scientists full of innovation and enterprising spirit are constantly bringing infinite possibilities for future technological transformations.The winners of the 2021 edition of “35 Innovators Under 35 China” by the 5th MIT Technology Review (TR 35) were released on January 22. Yiming Mo, a young PI from the Institute of Biological and Molecular Smart Manufacturing of ZJU-Hangzhou Global Scientific and Technological Innovation Center was on the list, and he delivered a speech on innovation at the Chinese webinar as the representative.The winners, on biology, chemistry, physics, astronomy, etc., are selected after a rigorous judging process for about one year, and the review is considered a major benchmark of Chinese young sci-tech power as it brought together 50 top science and technology leaders in the world. Ph.D. Yiming Mo, an outstanding young talent and doctoral supervisor at ZJU-Hangzhou Global Scientific and Technological Innovation Center, got his bachelor’s degree from Department of Chemical Engineering at Tsinghua University, and pursued his doctorate at Chemical Engineering Department, MIT under the tutelage of Professor Klavs F. Jensen, Academician of the National Academy of Engineering and National Academy of Sciences, the USA. With a wealth of cross-disciplinary research on electrochemical organic synthesis, high-throughput screening and artificial intelligence, Mo has so far published a number of papers on top journals, e.g. Science.  Why was Yiming Mo, a post-90s scientist, on the list?“MIT Technology Review” described his achievements as follows: He has realized the continuous intelligent pharmaceuticals manufacturing technology based on electrochemical microreactors and the world’s first nanomolar high-throughput microdroplet screening electrochemical platform to address increasingly pressing industrial needs for safety, green and miniaturization. So what exactly is the continuous intelligent pharmaceuticals manufacturing technology? What is the world’s first nanomolar high-throughput microdroplet screening electrochemical platform? What connection exists between them and ZJU-Hangzhou Global Scientific and Technological Innovation Center? Mr. Yiming Mo will share with us more. A greener and smaller pharmaceutical innovation technology for life and health is coming!Mr. Yiming Mo told us that rapid progress of pharmaceuticals technology has brought about better human health in modern times, and challenges in population growth and emergency public health need an adequate supply of pharmaceuticals in a more flexible, cheap and green way of production. Continuous intelligent pharmaceuticals manufacturing is not only a technology, but a new production paradigm as well. Traditional pharmaceutical production, usually in batch stirred tank reactions, has poor flexibility, unstable product quality, and low efficiency; while the continuous process uses flow chemical reactors for simultaneous input of raw materials and product output, which does not need the transfer of reaction intermediates as what traditional batch stirred tank reactors do, so it is an important technical means for continuous, miniaturized and safe pharmaceutical production. Since the technology makes flexible and miniaturized pharmaceutical production possible, it is of great significance to apply it in addressing drug shortages or public health emergencies.The continuous intelligent manufacturing technology of electrochemical microreactors, mainly developed by Mr. Yiming Mo, drives the oxidation/reduction reaction process by utilizing electric energy, controls the electrochemical reaction process precisely coupled with microreactor technology, and realizes the green synthesis of small pharmaceutical molecules with high atom economy. Being developed by ZJU-Hangzhou Global Scientific and Technological Innovation Center, the technology is making the pharmaceuticals manufacturing environment-friendly and granting it broad application prospects due to its easy operation and small size.The world’s first platform device for nanomolar-level high-throughput microdroplet screening electrochemistry For faster development of new electrochemical synthesis methods, Mr. Yiming Mo constructed the world’s first platform device for nanomolar-level high-throughput microdroplet screening electrochemistry by integrating automation and microfluidic technology, realizing the rapid screening of electrochemical reaction conditions and accurate measurement of reaction kinetics.The nanomolar level is 10-9 mol, which is far smaller than 10-3 mol, the micromolar level used in traditional experiments, which means a high-precision screening can be performed with a slight dose of experimental reagents and high-throughput devices such as intelligent robotic arms. iChemFoundry Platform Intelligent Robotic ArmThis platform device for nanomolar-level high-throughput microdroplet screening electrochemistry is currently one of the important modules of iChemFoundry platform of the Institute of Biological and Molecular Smart Manufacturing of the Center. Mr. Yiming Mo and his team members also constructed an orbital positioning system that requires the use of large stroke and high precision, which tackled two major engineering challenges of large stroke movement and high precision positioning.Mr. Yiming Mo said that “35 Innovators Under 35” is looking for innovative young scientists who can make a significant impact. He also hopes to attract more like-minded young partners to the Center to explore the world of continuous intelligent technology and cross-disciplinary studies, so as to bring more possibilities for sci-tech innovation.

With the rapid sci-tech progress in recent years, aerospace and automobile industries have placed higher requirements on the performance indicators of power electronic devices and the ability of the devices to work in harsh working environments, so a new generation of power electronic devices are expected to have excellent attributes, e.g. higher voltage resistance, higher switching speed, lower loss and high temperature resistance and can function well in harsh working environments like high temperature and strong irradiation.After the development for decades, the technology of traditional silicon-based semiconductor devices has become mature, and the performance of silicon-based devices has come to their physical limits, which means they are not up to the applications with high temperature, high pressure and high frequency, etc. Compared with silicon materials, silicon carbide (SiC) materials have a wider band gap width (3 times that of silicon), a higher critical breakdown electric field (10 times that of silicon), a higher thermal conductivity (3 times that of silicon), a higher intrinsic failure temperature (over 500 °C), more stable chemical properties and better irradiation resistance. SiC has these superior physical and electrical properties, so the power devices based on SiC materials are ideal for the applications with high temperature, high pressure, high frequency, and strong radiation.However, the current actual SiC MOSFET devices are confronted with serious challenges, such as total dose effects and single particle effects, poor radiation resistance and low stability, so they cannot satisfy the application requirements of aerospace avionics. Therefore, many problems are to be tackled in the research of the radiation effects of SiC MOSFET devices; for example, there lacks theoretical research on device radiation effects and failure mechanism, the test methods of device radiation effects and the evaluation methods of radiation resistance need to be improved, and the radiation hardening technology based on the innovative design of device structures and manufacturing improvement methods needs to be studied. The major participant of the project, REN Na, a young researcher in Power Chip Research Laboratory of Advanced Semiconductor Research Institute at ZJU-Hangzhou Global Scientific and Technological Innovation Center, will make full use of the research foundation and technical reserves of the team in silicon carbide power MOSFET devices, as well as the first-class experimental facilities and research capacity of the Center to cooperate with Yangtze Delta Region Institute of Tsinghua University, Zhejiang for the research and technological innovation on the “bottlenecks” in radiation resistance of silicon carbide power MOSFET so as to reveal the special radiation effect mechanism of silicon carbide MOSFET, break through traditional radiation hardening methods in silicon-based devices, propose a variety of new and efficient combinations of hardening technologies, implement all-round radiation resistance hardening for silicon carbide power MOSFET devices from multiple angles, change the inefficient single-point trial and error methods of the traditional hardening technologies of power MOSFET devices, improve the corresponding technical design rules, guide and develop the radiation resistant power MOSFET products in series.

Catfish effect in semiconductor field? A research team of ZJU-Hangzhou Global Scientific and Technological Innovation Center revealed the principle of “dilution effect” of organic photovoltaic devices

2021-12-22

Have you ever thought of a day like this?While the sunlight is streaming through huge French windows, the temperature inside the room is not rising at all; however the energy is stored and applied elsewhere quietly.This is not a dream; it is a research being conducted by scientists.Organic solar cells (or organic photovoltaic devices), applied with organic conjugated molecules (or polymers) as the photosensitive layer and prepared by solution processing, are characterized by low cost, light weight, flexibility, being colorful and translucent, so they are used for a wider range of scenarios, and can even be made into building glass.However, compared with silicon solar cells, organic solar cells still have low photoelectric conversion efficiency, which is one of the major obstacles to their industrialization. In recent years, it has been discovered that the co-blending of multiple organic dye molecules (i.e., multiple-blending strategy) can effectively improve the efficiency of photovoltaic devices; however, the principle still remains unknown, which also leads to the lack of material screening guidelines for multiple-component blending devices and being a hindrance for making high-performance devices.Dr. Zuo Lijian, a young PI at the Institute of Future Science, ZJU-Hangzhou Global Scientific and Technological Innovation Center, has made an important progress in this field by revealing for the first time the principle of “dilution effect” (organic dye molecular blending), which provides a basis for the screening of multiple-component blending device materials from the perspective of physical principles. The result entitled “Dilution effect for highly efficient multiple-component organic solar cells” was published in Nanotechnology, a series of Nature.Exercising “catfish effect” to activate the “still water” of organic photovoltaic devicesAs known to all, solar energy is currently an ideal clean energy. Solar cells at present, mainly of monocrystalline silicon devices, have the advantages of high conversion efficiency, long service life and others; however, they also have shortcomings, e.g. fragile texture, monotone color, high preparation costs and long energy return cycle. Therefore, organic photovoltaic cells have become a new R & D tendency.In comparison, organic photovoltaic cells show obvious advantages, e.g. light weight, simple fabrication, and broad application prospects as they can be used to prepare large area flexible devices with low-cost printing process. Therefore, it is the focus of current research to improve the efficiency of photovoltaic.Based on the previous experiments of other scholars, Dr. Zuo Lijian’s team revealed the principle of “dilution effect” for the first time. They found that when organic light-emitting dyes are dispersed in a wide band gap dye molecule, the band gap of the molecule will turn wider, the electron-vibration coupling be reduced, the non-radiative compound energy loss of the system reduced, and the photoelectric conversion efficiency improved. It is like putting catfish to a school of carp, the efficiency of fish movement will be increased. The study discovered further that the charge in the multiple-component blending system can be transferred “freely” at the interface of molecular heterojunction, which provides a theoretical basis for adding receptors to improve conversion efficiency.Based on this “dilution effect” principle, the research team proposed design guidelines for material selection of multiple-component organic photovoltaic devices, including compatibility, energy level structure, band gap and other requirements, and achieved success in the preparation of organic photovoltaic devices with a performance of up to 18.3%, which was a strong impetus to the industrialization of organic photovoltaics.Pursuing an “Industrial Dream” at the Center How to empower daily life with sci-technology innovation? Dr. Zuo Lijian, after getting his doctorate in Zhejiang University, has been making explorations in the research of materials and device performance structure-effect relationship and device physics. He used to work on the science of materials at the University of Washington. He has made breakthroughs in device performance through innovative design of materials and device structures, published 80-odd papers in Science Advances, JACS, Nature Communications and other top journals, and has been granted one patent.In his opinion, serving industrial progress with science and technology and disseminating scientific principles in a better way are as important as sci-tech innovations, so it is the reason that he chose to work for the Center. He hopes to realize his dream of “serving China with science and technology” on this platform.“I am currently engaged in research on perovskite at the Institute of Future Science of the Center. If the material used in organic solar cells is “plastic semiconductor”, which can be obtained through solution processing, then the material used in perovskite cells is “salt”, which is like a transition zone between silicon materials and solution-processable polymers, integrating the advantages of both, with important research value and broad application prospects!Zuo Lijian said that his research project is an interdisciplinary one of materials, chemistry, physics, optics and other areas, and the Institute of Future Science at the Center is dedicated to exploring these frontier technologies that may have a significant impact on industrial development in the future. “Research can not be carried out in closed doors; researchers should see the industry themselves, understand its real needs and conduct research with application value!”Together with his team members, he hopes to make good use of this high-energy multidisciplinary innovation platform to focus on such forward-looking research issues as the stability of perovskite solar cells and to provide research support for large-scale application and mass production of academic fruits.

Achievements of Mogan-1 and Tianmu-1 Superconducting Quantum Chips released

2021-12-17

On December 17, 2021, the academic results of Mogan-1 and Tianmu-1 superconducting quantum chips were released by Zhejiang University at ZJU-Hangzhou Global Scientific and Technological Innovation Center, proclaiming that quantum science and technology of Zhejiang Province is taking a big stride forward. Mr. Yan Jianhua, Standing Member of the CPC Committee and Vice President of Zhejiang University, Mr. Ni Shiying, Vice Mayor of Xiaoshan District, Academician Yang Deren, Chief Scientist of the Center, and Mr. Zhu Shiyao, Academician of the Quantum Computing Innovation Workshop, were present at the event and delivered speeches, encouraging the quantum team to bear the “Great ambitions of China” in mind and work for the key and core technologies. The event was hosted by Yang Jianyi, Director of the Center. Unveiling Tianmu-1 and Mogan-1 The protagonists today are two fingernail-sized chips in front of us: Mogan-1 and Tianmu-1 superconducting quantum chips. Mogan-1, a special quantum chip with a fully connected architecture, is applied to quantum simulation and precise regulation of quantum states for specific problems. The team, with Mogan-1 chip, has systematically investigated the Stark multibody localization in quantum multibody physics, a topic of great attention, and has characterized the Stark multibody localization from various perspectives, including the system’s memory of the initial state and the spatial scale of quantum entanglement. The result has been published in Physical Review Letters [127, 240502 (2021)], a leading journal in physics.The simulation of quantum multibody systems using superconducting quantum chips, an exciting area that differs from classical numerical simulations based on supercomputers, is a novel research tool that will greatly facilitate the study of complex multibody systems. The team has owned patented technologies related to fully connected architecture chips and will continue to develop further in this field to serve more scholars.Tianmu-1 chip, designed for general-purpose quantum computing, is applied with an easily scalable nearest-neighbor connectivity architecture. In order to perform relatively complex quantum gate circuit algorithms, 36 superconducting quantum bits with longer bit lifetimes (decoherence time about 50 microseconds) have been integrated into Tianmu-1 chip, realizing high fidelity general-purpose quantum gates (controlled phase gates with precision better than 98%).Compared with Mogan-1, Tianmu-1 has higher programming flexibility to perform quantum algorithms of varieties, so it can be applied to more research fields. The team has recently made breakthroughs in increasing coherence time, and the “Tianmu” chips with higher performances to be developed will continue to serve the society.In addition, apart from the self-developed and prepared Mogan-1 and Tianmu-1, the team has had a full-stack R&D capability from superconducting quantum chip design, preparation, packaging to measurement and control. Meanwhile, the team has also built an integrated quantum measurement and control platform with advanced world level, which can be used for a variety of complex quantum experiments.Based in Zhejiang, Serving China and Facing the WorldThe R & D team of Mogan-1 and Tianmu-1 is led by Academician Zhu Shiyao, an expert in quantum optics, professor of physics at Zhejiang University and chief scientist of the Quantum Computing Innovation Workshop of ZJU-Hangzhou Global Scientific and Technological Innovation Center. Academician Zhu said China has reached the advanced world level in some parts of quantum information and quantum communication; however, the sci-tech progress is just like a race of running. We will be lagging behind if we don’t run faster than others, as every country is running hard.  Rome was not made in one day. Zhejiang University began to layout its superconducting quantum computing more than ten years ago and the Quantum Computing Innovation Workshop of ZJU-Hangzhou Global Scientific and Technological Innovation Center was set up in 2021, providing holistic support for quantum R & D. With the participation of more members, the team has been devoting their youth and energy to the quantum science and technology of China. In recent years, the team has achieved a series of research results and published 20-odd articles in Science, Nature Physics, Physical Review Letters and other top journals as the primary author. Many of the team members in this project were born after 1990s, and they are the young force, running day and night, for the research and development of quantum technology, as commented by Academician Zhu. Key Members of the R & D TeamThey claimed that “Mogan” and “Tianmu”, named after the famous Mogan Mountain and the Tianmu Mountain of Zhejiang Province, symbolize the ambition of the team to be based in Zhejiang, serve China and face the world. The researchers believed quantum computers have great prospects for application. Though at an initial stage, the quantum information era will be realized with the concerted efforts of researchers.  What is superconducting quantum chips?Quantum computing is a major area of quantum technology applications. Recently, the R & D of quantum computers has become a top-notch field of global science and technology strategy that every country is vying for and quantum chip development is the core of quantum computer research.Quantum bit is the basic unit in quantum computing. Unlike classical bits, which are either 0 or 1, a quantum bit can be in both 0 and 1 states, and when the number of quantum bits increases, the corresponding state shows an exponential explosion carrying more information, which is the key to quantum acceleration. Superconducting quantum chips, electronic circuits based on superconducting Josephson junctions, can be flexibly constructed by semiconductor micro and nano processes, so they are considered the most promising and practical of quantum chips.Three dimensions: the number of quantum bits, decoherence time (the lifetime of quantum bits), and manipulation precision, are generally used to evaluate superconducting quantum chips. A practical superconducting quantum chip is one which takes into consideration the three dimensions. Only when the three dimensions reach good indexes can quantum computing be realized quickly and precisely.

What will happen when the Periodic Table of Chemical Elements meets AI model? The new achievement of ZJU-Hangzhou Global Scientific and Technological Innovation Center will give us the answer.

2021-12-09

What will happen when the Periodic Table of Chemical Elements meets AI model?“Molecular Contrastive Learning with Chemical Element Knowledge Graph”, the latest research achievement by Dr. Zhang Qiang, Qiushi Sci-tech Scholar (among the Global Recruitment Program of 100 Talents) and his team of ZJU-Hangzhou Global Scientific and Technological Innovation Center has brought us imagination. In this innovative achievement, first the Periodic Table of Chemical Elements was constructed  into Chemical Element Knowledge Graph and then the Graph was incorporated into AI model to build a new AI framework for Knowledge-enhanced Molecular Contrastive Learning, which is expected to be widely applied in biomolecular research and compound synthesis research, e.g. the prediction of toxicity properties of compound molecules.Currently, the research has been accepted by AAAI2022, a top international AI conference, from nearly 10,000 submissions worldwide, with Dr. Fang Yin and Dr. Zhang Qiang as the first authors and Prof. Chen Huajun as the corresponding author. Molecular Contrastive Learning with Chemical Element Knowledge GraphKnowledge Graph aims to describe the concepts, entities, and events in the objective world and their relationships. In the Knowledge Graph, “Entity” is used to express the nodes in the Graph and “Relation” to express the “edges” in the graph. Entities refer to the objects in the real world, such as persons, institutions, chemical elements, genes, proteins, while relationships to express the connections between entities, such as a person-“lives in”-Beijing, Zhang San and Li Si are “friends”. Knowledge graphs are applied extensively in search engines, intelligent question and answer, recommendation computing, language understanding, big data analysis, device IoT, and other fields. Contrastive Learning on Graph, put it simply, is a self-supervised learning algorithm for graph data. For a given large amount of unlabeled graph data, the graph contrastive learning algorithm, instead of designing a complex pre-training task, only aims to train an encoder, the graphs encoded from which are vectors, so the properties of the graph data can be preserved.In recent years, Learning on Molecular Graphs has come to be applied to several downstream tasks in biology, chemistry, and pharmaceuticals, such as molecular property prediction and drug designs, with unlimited prospects. However, previous studies failed to incorporate domain scientific knowledge into Learning on Molecular Graphs, ignoring the microscopic connections between domain knowledge and atoms embedded in molecular graphs.Chemical Element Knowledge Graph establishes the relationships between atoms that are not connected by chemical bonds but have related chemical propertiesTo address this problem, Dr. Zhang Qiang, under the guidance of Prof. Chen Huajun from College of Computer Science and Technology of Zhejiang University, led his members to conduct interdisciplinary research by constructing Chemical Element Knowledge Graph based on the integration of AI models and the Periodic Table of Chemical Elements, which describes the microscopic connections between elements and the domain scientific knowledge related to each element. In addition, a new Knowledge-enhanced Contrastive Learning (KCL) framework for molecular graphs was proposed.Knowledge-enhanced Contrastive Learning (KCL) frameworkThis new Knowledge-enhanced Contrastive Learning (KCL) framework for molecular graphs consists of three modules: Knowledge-enhanced graph module, knowledge-aware graph representation module, and contrastive learning target module. The knowledge-enhanced graph module expands the original molecular graphs based on knowledge graph (KG) with chemical elements. The knowledge-aware graph representation module extracts molecular representations from the original molecular graph using a generic graph encoder, and encodes complex information in the enhanced molecular graph using the Knowledge-aware Message Passing Neural Network (KMPNN). The contrast learning target module constructs a contrast loss function by maximizing the consistency between positive sample pairs and the variability between Hard negative pairs (HNPs) to optimize the model.The research of the team also explained what Knowledge-enhanced Contrastive Learning (KCL) learns from atoms and attributes in the augmented molecular graph through a large number of visualization experiments in multiple real-world scenarios, thus demonstrating that KCL achieves better performance than the advanced baseline on eight molecular datasets. Experiencing Infinite Interdisciplinary Possibilities at the CenterDr. Zhang Qiang, Qiushi Sci-tech Scholar (among the Global Recruitment Program of 100 Talents), got his Ph.D degree from University College London (UK), and his research covers machine learning, data mining, natural language processing and biomolecular intelligence, etc. He has participated in several major research projects funded by the Engineering and Physical Sciences Research Council (EPSRC), the UK and companies such as Google and has published a number of papers in NeurIPS, ICML, AAAI, WWW, TOIS, top academic conferences and SCI journals on artificial intelligence.As a young scholar with rich experience in research and industrial projects, Zhang Qiang were favored by several top Internet organizations when he returned to China, but he chose ZJU-Hangzhou Global Scientific and Technological Innovation Center after careful consideration.“Because I see more possibilities at the Center, I am very much looking forward to AI for Science, and also hope to see the paradigm shift, Science for AI, which will be innovative and meaningful.” The Research Institute of Biological and Molecular Smart Manufacturing at the Center where Dr. Zhang Qiang is working is in great need of AI-related knowledge at promoting research in biological and molecular smart manufacturing with high-throughput technologies.Zhang Qiang said, as an expert in computer science and technology, he had never thought he would be so closely related to biology and chemistry. Every day at the Center, he experiences great brainstorming when he meets young scholars from different fields, and sometimes there may be a new idea after a casual chat. He said, “Our research integrates the knowledge of computer science and technology, chemistry, biology and others, and the interdisciplinary research between knowledge graph and AI model can help us better predict the properties of molecules, so it can be widely applied in biomedical field with a wide range of scenarios.”In an open and interdisciplinary landscape, Zhang Qiang hopes to meet more like-minded friends and colleagues to achieve more in scientific research at the Center in a cooperative manner and finally contribute young power to scientific innovation together!
