Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation
Advanced Functional Materials, EarlyView.This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Modeling of H/D isotope-exchange in crystalline beryllium
Nuclear Materials and Energy, 2019 A reaction-diffusion model with surface occupation dependent desorption [D. Matveev et al., Nucl. Instr. Meth. B 430 (2018) 23–30] has been updated to handle multiple hydrogen species to simulate hydrogen/deuterium isotope-exchange experiments performed ...

ON THE QUANTUM THEORY OF ISOTOPE EFFECTS IN ELECTROMIGRATION AND THERMOMIGRATION OF LIGHT INTERSTITIALS [PDF]
, 1973 The electromigration and thermomigration of light interstitials, such as hydrogen in metals, have been examined in terms of the quantum theory of diffusion of Flynn and Stoneham.

Enhanced production of HD and D_2 molecules on small dust grains in diffuse clouds
, 2003 Motivated by recent observations of deuterated molecules in the interstellar medium, we examine the production of HD and D$_2$ molecules on dust grain surfaces. A mechanism for the enhanced production of these deuterated molecules is studied.
