CuInSe2/ZnS quantum dots are synthesized in water and coupled with chlorophyll to probe ligand‐controlled excited‐state interactions. Broad visible–NIR emission and high PLQY are observed. Time‐resolved measurements reveal shortened chlorophyll lifetimes, indicating dynamic quenching via Förster energy and/or charge transfer, highlighting surface ...

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Development of an x-ray excited optical luminescence microscope (XEOM) [PDF]
X-ray excited optical luminescence (XEOL) refers to the trans-visible emission produced as a consequence of X-ray bombardment and provides an alternative detection method for X-ray absorption spectroscopy (XAS). Whereas XAS measured by conventional means

Gas‐Selective Remote Plasma Engineering of WO3 Photoanodes for Solar Water Splitting
Gas‐selective remote plasma treatment tunes the near‐surface defect chemistry of WO3 photoanodes without altering their bulk structure. Ar plasma generates the most oxygen‐vacancy‐rich surface and the highest W5+ content, delivering the strongest photocurrent.

This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
