Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Effects of crystallization on micro-mechanical behavior of polyethylene nanocomposites using Raman spectroscopy

Nanocomposites
Recent work has shown that nanoparticles can be ordered in semicrystalline polymers by controlling the crystallization rate, specifically by forcing them to migrate to the amorphous regions of the lamellar morphology.

Inhomogeneous elastic response of silica glass

, 2006
Using large scale molecular dynamics simulations we investigate the properties of the {\em non-affine} displacement field induced by macroscopic uniaxial deformation of amorphous silica,a strong glass according to Angell's classification.

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation

Advanced Materials Interfaces, EarlyView.
Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...

Flow boiling-driven intensive growth of critical minerals during short-lived events

Scientific Reports
Enrichment of critical metal tellurium (Te) in shallow crustal settings is often linked to hydrothermal boiling, yet the mechanisms driving Te-silica co-precipitation under dynamic fluid flow conditions remain unresolved.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
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 ...

Pressure-induced amorphous-amorphous transition in pre-densified silica glass: an experimental exploration of the potential energy landscape

Scientific Reports
Despite the difficulty of experimentally studying polyamorphic transitions in high-Tg glasses, it is well known that silica glass has two high-density phases: the cold-compressed and hot-compressed high-density amorphous phases (c-HDA and h-HDA).
