TL;DR: An inexpensive 2-bit programmable coding metasurface working at around 3.2 GHz along with an efficient optimization algorithm for the generation of high-order OAM-carrying beams in a reprogrammable way is explored and it is believed that the developed strategy will bring a fundamentally new perspective on the design of wireless communication architectures at various frequencies.

TL;DR: Temperature-dependent SERS experiments and their two-dimensional (2D) correlation analysis confirmed that the formation of H-bonds facilitated the CT transition between the adsorbed molecules and substrate and the degree of CT was reduced by H- bond breakage that occurred with increasing temperature.

TL;DR: In this article, a detailed molecular beam epitaxial growth and characterization of Al(Ga)N nanowire heterostructures on Si and their applications for deep ultraviolet light emitting diodes and lasers are reported.

TL;DR: Surprisingly, it is found that the alkyl chains determine the orientation of the molecular overlayers of the Ag substrate, enabling uniform QA films with very well controlled physical properties.
