Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Hydrofluoroether Synthesis through One‐Pot Anodic Iodoalkoxylation of Alkenes

Advanced Synthesis &Catalysis, EarlyView.
Abstract The incorporation of carbon‐fluorine bonds can profoundly influence the chemical and physical properties of drugs, agrochemicals, and materials. Different methods allow the installation of CF3, CF2H units and C−F bonds including trifluoro‐ and difluoromethoxylations, reflecting the limited diversity of reactions available to synthetic chemists.
