Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

Advanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Ratiometric Temperature Sensing through Alternating Current Electroluminescence

Advanced Optical Materials, EarlyView.
Thermoresponsive alternating current electroluminescence (ACEL) is realized in ZnS microparticles with optimized Cu, Cl, and Co tri‐doping concentrations, exhibiting a blue‐to‐green emission band shift along with increasing temperature. Based on this behavior, an ACEL‐driven temperature sensing platform is developed for quantitative temperature ...

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...
