Despite the promise of silk-based devices, the inherent disorder of native silk limits performance. Here, we report highly ordered two-dimensional silk fibroin (SF) films grown epitaxially on van der ...

Topological defects are universal patterns of nature. Nematic liquid crystals are ideal test beds for studying defects, particularly one-dimensional, linear disclinations. Predicting the structure of ...

Rust is an incredible powerful programming language. It is fast, compiled, without a runtime and it brings new concepts of safety to programming. It is the most beloved language for five years in a ...

Recent rapid advances in spatiotemporal optical pulses demand accurate characterization of the spatiotemporal structure of the produced light fields. We report an automated close-loop characterization ...

Enabled by multiple optical traps, holographic optical tweezers can manipulate multiple particles in parallel flexibly. Spatial light modulators are widely used in holographic optical tweezers, in ...

Classical nucleation theory predicts that two-dimensional islands on a surface must reach a critical size before they continue to grow; below that size, they dissolve. Chen et al. used phage display ...

The manipulation of light by conventional optical components such as lenses, prisms, and waveplates involves engineering of the wavefront as it propagates through an optically thick medium. A unique ...
