Nanocrystal Quality–Controlled Scintillation in Porous YAG:Ce Aerogels

Advanced Optical Materials, EarlyView.
High‐temperature thermal treatment of YAG:Ce nanoscintillator aerogels increases light yield under ionizing radiation by up to eightfold without affecting timing performance. Additionally, low‐temperature atmospheric treatments reversibly modify the cerium oxidation state, revealing strong defect sensitivity and offering new strategies to optimize ...

Effective control of intrinsic impurities using n = 1 resonant magnetic perturbation (RMP) in EAST H-mode plasma

Nuclear Materials and Energy
Since 2021, EAST tokamak has been operated with full tungsten divertors. Tungsten accumulation has been frequently observed in NBI-heated H-mode discharges, resulting in the degradation of plasma confinement performance.

Investigation of RMP effects on W transport in the pedestal region in an ITER 15 MA H-mode scenario, using the nonlinear MHD code JOREK

Nuclear Fusion
Heavy impurities, such as tungsten (W) accumulating in the confined plasma core of tokamaks are detrimental to their performance and can lead to plasma disruptions due to radiative collapses.

Effects of stoichiometry, purity, etching and distilling on resistance of MgB2 pellets and wire segments [PDF]

, 2002
We present a study of the effects of non-stoichiometry, boron purity, wire diameter and post-synthesis treatment (etching and Mg distilling) on the temperature dependent resistance and resistivity of sintered MgB2 pellets and wire segments.
