How to set up government-led national hygiene communication campaigns to combat COVID-19: a strategic blueprint

BMJ Global Health, 2020
While large-scale changes in population behaviour are required to reduce the transmission of the severe acute respiratory syndrome coronavirus 2 virus, the emergency context is not conducive to the sort of careful communications planning that would ...

Self‐Powered Visible‐Blind Graphene/NiO/ZnO UV‐C Photodiodes

Advanced Optical Materials, EarlyView.
“A scalable architecture for self‐powered UV‐C photodiodes integrates defect‐engineered p‐NiO/n‐ZnO heterojunctions with highly UV‐C transparent graphene anodes. The type‐II band alignment combined with the built‐in electrical field enables robust zero‐bias charge separation.

GeSn Quantum Wells for Room‐Temperature Mid‐Infrared Lasing on Si and on Insulator Platforms

Advanced Optical Materials, EarlyView.
This work demonstrates a high‐performance GeSn‐on‐Insulator (GeSnOI) platform achieving laser emission up to room temperature. By utilizing Group IV GeSn quantum well heterostructures, we successfully reached a target wavelength of 3.3 µm. This advancement paves the way for fully integrated Mid‐IR photonic CMOS‐compatible sources, overcoming the ...

Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery

Advanced Optical Materials, EarlyView.
Optically trapped whispering‑gallery microlasers are precisely positioned onto non‐phagocytic mammalian cells to report local refractive‑index changes in real time. Time‑dependent wavelength shifts reveal successive stages from membrane contact to internalization.

Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements

Advanced Optical Materials, EarlyView.
This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).
