The field of biohybrid robotics focuses on using biological actuators to study the emergent properties of tissues and the locomotion of living organisms. On the basis of models of swimming at small size scales, we designed and fabricated a ...
Binary host-guest strategy enables bright and efficient lead-free zero-dimensional tin halide light-emitting diodes [0.03%]
二元宿主-客体策略实现高效明亮的无铅零维锡卤化物发光二极管

Enhancing the piezoelectric or strain response of materials through nanodomain engineering has proven to be highly effective. Here, we demonstrate that topological bubble domains (BDs) can be induced in Bi0.5Na0.5TiO3 (BNT)-based thin films...
Interleaved dual-species arrays of single atoms using a passive optical element and one trapping laser [0.03%]

Multidimensional optical data storage is a critically needed technology in the digital era. To overcome the low data writing rate in the conventional systems, we present a parallel five-dimensional optical data writing method by projecting ...
Pronounced methane cycling in northern lakes coincided with a rapid rise in atmospheric CH4 during the last deglacial warming [0.03%]
上一个冰期结束时，北部湖泊甲烷循环活跃与大气中甲烷快速增加相吻合
