Modelling of Optical Damage in Nanorippled ZnO Produced by Ion Irradiation
Crystals, 2019 Here, we report on the production of nanoripples on the surface of ZnO bulk substrates by ion beam erosion with 20 keV Ar+ ions at an oblique incidence (60°).

Carbon Energy, EarlyView.A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

S‐Doped Carbon Nitride Thin Films From a Triazole Precursor
Carbon Innovation, EarlyView.Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.

EcoEnergy, EarlyView.This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Applications of spectroscopic ellipsometry to microelectronics
Thin Solid Films, 1993 Ellipsometry has been applied to problems in the microelectronics industry from the beginning in the 1960's. More recently spectroscopic ellipsometry has been introduced. In-situ during process ellipsometry offers great promise for monitoring and control of a wide variety of microeletrcnics processes.
