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 ...

Temperature dependent control of the solubility of gallium nitride in supercritical ammonia using mixed mineralizer

Chemistry Central Journal, 2018
Using a mass-loss method, we investigated the solubility change of gallium nitride (GaN) in supercritical ammonia with mixed mineralizers [ammonium chloride (NH4Cl) + ammonium bromide (NH4Br) and NH4Cl + ammonium iodide (NH4I)].

Criticality and convergence in Newtonian collapse [PDF]

, 2002
We study through numerical simulation the spherical collapse of isothermal gas in Newtonian gravity. We observe a critical behavior which occurs at the threshold of gravitational instability leading to core formation. For a given initial density profile,
