Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals
Advanced Materials, EarlyView.Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

Affordable Biogenic Anti‐Icing Surfaces
Advanced Materials Interfaces, EarlyView.The article explores affordable biogenic coatings that prevent icing by combining coconut shell charcoal with natural hydrophobic agents such as beeswax. It shows how particle size and surface treatment influence water repellence, heat absorption, and self‐cleaning ability.

Morphology vs. Specific Surface Area: Which Plays the Leading Role in Microwave Absorption?
Advanced Materials Interfaces, EarlyView.The role of morphology and specific surface area on microwave absorbing characteristics is systematically evaluated and compared. The matrix effect on microwave absorbing performance is studied using polyacetylurea. Implanted carbon nanotubes by red phosphorus and in situ polymerization of polyindole promoted microwave absorption.
