Scanning X-ray microscopy focuses radiation to a small spot and probes the sample by raster scanning. It allows information to be obtained from secondary signals such as X-ray fluorescence, which yields an elemental mapping of the sample no...
Challenges in protein folding simulations: Timescale, representation, and analysis [0.03%]

In physical, biological, technological and social systems, interactions between units give rise to intricate networks. These-typically non-trivial-structures, in turn, critically affect the dynamics and properties of the system. The focus o...
Electronic dynamics created at conical intersections and its dephasing in aqueous solution [0.03%]
锥形交叉处产生的电子动力学及其在水溶液中的去相位现象
A dynamical rearrangement in the electronic structure of a molecule can be driven by different phenomena, including nuclear motion, electronic coherence or electron correlation. Recording such electronic dynamics and identifying its fate in...
