Ruoping Li

TL;DR: In this paper, the authors show that for a moving droplet, the film thickness follows the Landau-Levich-Derjaguin law and the droplet is therefore oleoplaning with minimal dissipative force and no contact line pinning.

TL;DR: It is found that the dissipative force-due to very different physical mechanisms at the contact line-is independent of velocity on superhydrophobic surfaces but depends nonlinearly on velocity for flat and lubricated surfaces.

TL;DR: This work shows that a metasurface grating can be designed to produce arbitrarily specified polarization states on a set of defined diffraction orders given that the polarization of the incident beam is known.

TL;DR: A platform for tunable polariton refractive and meta-optics based on hexagonal boron nitride and phase change Ge3Sb2Te6 is experimentally demonstrated, which will enable the realization of programmable miniaturized integrated optoelectronic devices and on-demand biosensors based on high quality phonon resonators.

TL;DR: In this paper, the authors test four fiber-optic attenuator types used in quantum key distribution systems, and find that two of them exhibit a permanent decrease in attenuation after laser damage.
