Minimal flow anesthesia can be initiated early with the use of higher fresh gas flow to facilitate desflurane “Wash-in”

open access: yesJournal of Anaesthesiology Clinical Pharmacology, 2019
Background and Aims: More than 80% of delivered anesthetic gases get wasted at high fresh gas flows as they are vented out unused. Use of minimal flow anesthesia is associated with less waste anesthetic gas emission and environmental pollution.

Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Microcapsule‐Mediated Vibration‐Induced Emission for Real‐Time Visualization of Polymer Deformation

open access: yesAdvanced Optical Materials, EarlyView.
A mechanochromic microcapsule is reported that combines vibration‐induced luminescence (VIE) with mechanically controlled release functionality. By embedding the microcapsules into a polymer matrix, the conformational changes of VIE molecules can be precisely amplified into visual fluorescent color signals, enabling real‐time, high‐sensitivity ...
