Thermal accommodation in nanoporous silica for vacuum insulation panels
International Journal of Thermofluids, 2020 The thermal accommodation coefficient is a measure for the quality of thermal energy exchange between gas molecules and a solid surface. It is an important parameter to describe heat flow in rarefied gases, for example, in aerospace or vacuum technology.

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures
Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Advanced Materials, Volume 38, Issue 21, 13 April 2026.We present a microfabrication and integration strategy for lead halide perovskite photodetectors on electronic readouts. Standard photolithography, aqueous processing, selective transparent electrode etching, and plasma‐assisted pixel isolation enable precise monolithic integration of patterned 400 × 400 perovskite microphotodetector arrays on a CMOS ...
