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 ...

Advanced Photonics Research, EarlyView.This study investigates sodium fluoride (NaF) as an additive in halide perovskite films to improve their optical and light amplification properties for application in laser diodes. The incorporation of NaF leads to a threefold increase in light‐emitting intensity and a 20% reduction in the amplified spontaneous emission (ASE) threshold, along with ...

Advanced Robotics Research, EarlyView.Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.

Advanced Sustainable Systems, EarlyView.The electronic modulation of Nb‐doped Co3O4 catalyst showcases enhanced activity and extended stability for OER in both alkaline (1M KOH) and acidic (0.5M H2SO4) electrolytes. The higher activity emanated from the synergistic effect between the Nb5+ dopant and Co3O4.
