Hua Xiao began to study a class of lithium-ion battery cathode materials, metal fluorides, as early as the master's stage, including its structure, morphology, and the mechanism of the reaction during charging and discharging. Since the electrochemical reactions of metal fluorides are extremely complex and involve multiple intermediate phases that are difficult to characterize, the reaction mechanism has been controversial in the academic circle. Over ten years, from a master's degree to a post-doctoral fellow, Hua Xiao has been constantly learning, breaking through the boundaries of knowledge and technology, combining advanced experiments and analysis methods such as X-ray diffraction, PDF and NMF (Non-negative Matrix Factorisation), and finally broke through solved this problem.

Is Spider-Man related to neurological diseases such as Alzheimer's? This is something I wouldn't have thought of before I communicated with Dr. Shen Yi. Her research on protein has given us some inspiration to explore the magical natural forces behind it. What's even more amazing is that the principles may not only apply to biological problems, but can also be used to design new materials. When asked about the deepest driving force behind these changes and principles, Dr. Yi Shen summed up life, science and scientific research: not only protein molecules and their transformations, but our lives are also fighting against the second law of thermodynamics process. We have to give ourselves extra energy, we have to overcome obstacles and move away from the most stable state, we have to be active in an unstable state all the time, so that we can grow.

Behind an "artificial leaf" that can both decompose water and reduce carbon dioxide is not only a novel idea derived from nature, but also requires more than ten years of hard work in the field of artificial photosynthesis and a willingness to travel around and gather the strengths of hundreds of schools. . In the conversation with Dr. Wang Qian, our deepest feeling is the perfect compatibility of "focus" and "openness". What degree of focus should be achieved - adhering to the spirit of craftsmanship to create a world record for the efficiency of water splitting and conversion; to what degree of openness should be achieved - learning from the east and the west, accommodating all rivers, combining the best characteristics of Dongda and Cambridge in scientific research, bursting out new inspiration. While concentrating on scientific issues, Dr. Wang Qian never forgets to look up to the industrial world, actively explore the possibility of the combination of industry and academia, and find the most suitable soil for it to take root and germinate.

Throughout the history of human science, the understanding of the mechanisms behind everything in the world has become more and more nuanced. A stone from the Stone Age can now be modeled at the atomic scale, simulate properties, and even design and predict new multifunctional materials. The exploration of the origin of matter and phenomena in the world drives the progress of science and society, but there are still many seemingly common systems that cannot be completely simulated under the existing computing resources, and the complexity of the system affects the physical model. The establishment puts forward higher requirements. At the same time, the vigorous development of computer science, especially the concept of machine learning, has greatly released the computational complexity that cannot be achieved under traditional algorithms. When machine learning meets physics and materials science, what is the story?

The art of origami originated in the Northern and Southern Dynasties of China, developed in Japan, spread to Europe and the United States, and popularized the world. For more than 1,500 years, the modern art of origami has developed to an unprecedented level. A piece of ordinary paper can be folded into many complex and lifelike exquisite works of art. Maybe many people have folded a lot of interesting little toys when they were young, but people rarely think about whether origami has other meanings besides artistic aesthetics and entertainment value. In recent years, origami has entered a new field of research from handmade art. The mathematical operations and spatial geometry principles behind it are constantly being discovered, and combined with the theoretical knowledge of physics, structure, materials and other interdisciplinary disciplines, and gradually applied to biomedicine , civil engineering, aerospace and many other cutting-edge science and technology fields. Origami is a complex three-dimensional structure conceived in advance by designing the folds of a flat material and folding it, and the final structure and its physical properties also mainly depend on its folding method. Therefore, the systematic theoretical research on crease design and folding trajectory is crucial for realizing the programmable design and precise control of origami structures.

Semiconductors occupy an important position in modern information technology. Organic semiconductors combine the electronic performance advantages of traditional semiconductors with the chemical and mechanical properties of organic materials. Therefore, the electronic properties of organic semiconductors can be tuned by changing the molecular structure through chemical synthesis. There is still huge potential for the development of organic semiconductor industry in the future. Therefore, researchers need to have a further understanding of the interaction between photons and organic semiconductors, the generation, transmission, collection and other physical processes of excitons in organic semiconductors. During his Ph.D., Dr. Feng studied the effects of solid-state interactions on triplet excitons in organic semiconductors, including the diffusion process of excitons, the electrostatic interactions between molecules and the surrounding environment, the link between molecular conformation and photophysical properties, and heavy atom effects. Effects on triplet excitons. This knowledge can be manipulated at the microscopic scale to improve energy conversion efficiency, enabling large-scale production and applications.

Microfluidics is an important scientific research method, which is widely used in various biological, medical and other fields. In the future, the diversification of microfluidic technology will drive the refinement of application scenarios, and will be applied to fields such as organ chips, liquid biopsy, biochemical analysis, and new drug research and development, and will become a "disruptive technology" for the next generation of medical diagnosis. Dr. Ziyi Yu not only carried out original scientific research work on microfluidic research, but also explored different application scenarios of microfluidic technology, transformed related technologies into high-tech products, and successfully started a business in the field of biomedicine - truly doing When it comes to the combination of production, education and research, it will create value for the society. Let us understand the effort, thinking and vision behind these achievements from his first perspective.

As we all know, the life of mammals such as humans begins with a fertilized egg formed by the combination of sperm and egg, and after a complex early embryonic development process, a large and complex life individual is born. Embryonic development is a process of inverse entropy from disorder to order. After fertilization, the chromosomes without gene expression are activated and the whole is precisely regulated. The cells gradually differentiate into cell types with various single functions and perform their respective functions, and finally form different human tissues, systems and organs. However, the mechanism behind the early embryonic development process has been a great mystery in the field of developmental biology since its discovery in the 1980s. The whole process is as complex and orderly as a symphony, as if there is a hand of God driving everything in an orderly manner in the dark. But now the mystery is gradually being answered. With great enthusiasm for early embryo development, Dr. Zhu Meng has been working in the field for several years. She innovatively jumped out of traditional biological research methods, and used quantitative cell imaging methods combined with biophysical modeling to systematically reveal for the first time the principles behind the process of cell polarization in early embryonic development. Her discovery of cytokines that regulate cell polarity fills the gap in related fields and establishes an important research foundation for the treatment of infertility, other fetal developmental disorders, and human regeneration science.

Astrobiology is an interdisciplinary subject that studies the origin, evolution, distribution and future development of life in the universe. It is not limited to life on earth, but also includes the study of extraterrestrial life. It originated from the discovery and research of extremophiles in recent years. Since extremophiles can live in extreme environments such as high temperature, low oxygen, anhydrous, high salinity, and high pressure, the scientific community has begun to pay attention to the possibility of organisms surviving on other planets, as well as the origin of life on the early Earth. Sci-fi visions of the origin of life are fascinating, and astrobiology is just as cool and interesting.
