Fermi and intramode relaxation phenomena in CO2lasers [PDF]
, 1987 Using a 1 ns pulse from a short-pulse CO2laser system, the evolution of the gain in a TEA system was studied during and after amplification. This resulted in a very direct observation of a few relaxation processes.

Advanced Healthcare Materials, EarlyView.Ionizable lipid nanoparticles target multiple pathological pathways in neurodegeneration. The designed self‐assembled materials undergo a pH‐triggered structural transformation from a cubosome/hexosome coexistence to a hexosome phase, enhancing intracellular delivery of a multi‐target phytochemical formulation. The antioxidant‐loaded pH‐responsive LNPs

A Colloidal Quantum Dot Thermistor and Bolometer
Advanced Materials, EarlyView.This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space
Advanced Materials, EarlyView.In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

A 5-nV/√Hz Chopper Negative-R Stabilization Preamplifier for Audio Applications
Micromachines, 2020 This paper presents a low-noise and low-power audio preamplifier. The proposed low-noise preamplifier employs a delay-time chopper stabilization (CHS) technique and a negative-R circuit, both in the auxiliary amplifier to cancel the non-idealities of the
