Peking University, Sep. 25, 2015: The three-dimensional topological Dirac semimetal, as a new type of topological materials, has attracted great attention in condensed matter physics. There, the conduction and valence band touch only at discrete points and disperse linearly along...

Peking University, Sep. 1, 2015: Where did our genes come from? Scientists agree that new genes predominantly develop from a biological process called “gene duplication”. Recent studies have brought in a new idea: new genes might also come from non-coding DNA regions...

Peking University, Aug. 30, 2015: Low-dimensional materials have attracted a wide spread attention due to their unique electronic and structural properties for new physical phenomena. MoS2 monolayers are a kind of two-dimensional materials, which have been a hot research topic in...

Peking University, July 28, 2015: Recently, Prof. Duan Huiling’s group from the Department of Mechanics and Engineering Science, College of Engineering, reported new findings for the understanding of PM2.5 airborne pollutants through nanoscale characterization. This work ha...

Peking University, July 22, 2015: Recently, the research team led by Professor Yu Haifeng from College of Engineering of Peking University has made an important progress in the photoresponsive liquid crystal and micro/nano composite materials. The results titled “Optical Pe...
