Peking University’s research projects win the 2020 National Science and Technology Awards

NOV . 11 2021
Peking University, November 11, 2021: On the morning of November 3, 2021, the 2020 National Science Award Conference  was held in the Great Hall of the People. Peking University received 6 awards in total, including a first-place National Technological Invention Award, one second-place National Technological Invention Award and four second-place National Natural Science Awards.
 
Gao Wen

Prof. Gao Wen from School of Electronic Engineering and Computer Science and his team won the first place National Technological Invention Award, for they invented the key technology of ultra-high-definition (UHD) polymorphic primitive encoding and decoding and formed a complete technical system with independent standards of AVS series, which supported the launch of China’s first UHD channel CCTV-4K, with direct economic benefits of more than 7 billion yuan in recent three years.
 
Yang Huai

Prof. Yang Huai from PKU College of Engineering and his team won the second place National Technological Invention Award. Their works broke through the existing technical bottlenecks and created a new system of polymer-dispersed coexisting with stabilized liquid crystal (PD&SLC). A series of high-performance liquid crystal and dimming films have been developed based on their achievements.
 
Liu Ruochuan

Prof. Liu Ruochuan from School of Mathematical Sciences and his team won the second place National Natural Science Award. They made significant progress in the basic theory and application in p-adic Hodge Theory and noncommutative p-adic Hodge Theory.
 
Li Yan

Prof. Li Yan from College of Chemistry and Molecular Engineering and her team won the second place National Natural Science Award, for the development for a series of catalyst systems for the synthesis of single-walled carbon nanotubes. Based on catalyst design, Li’s group proposed a new strategy the growth of single-chiral nanotube, which offers solutions to a two-decade problem in this field.
 
Chen Peng

Prof. Chen Peng from College of Chemistry and Molecular Engineering and co-worker won the second prize of National Natural Science Award, for their developed chemical reactions and tools suitable for living cells. They established a “chemical toolbox” for living cells and broke through the technical bottleneck of in-situ research on protein function, guiding China into the international frontier in relevant research fields.
 
Duan Huiling

Prof. Duan Huiling from College of Engineering and her team won the second place National Natural Science Award. They developed a non-classical Eshelby system with interface effects and a micromechanical theoretical framework on composites, providing a new scientific basis for the extensive mechanical behavior of composites with interface effects.
