In this study, Li 2 Ge 4 O 9 : Mn 4+ transparent glass-ceramic was prepared by conventional melt-quenching. The thermal treatment used for the devitrification of sample. creation a nanocrystalline precipitated through glass matrix verified X-ray diffraction and HR-TEM. Electron paramagnetic resonance spectra were employed to confirm oxidation 2+ in after treatment. photoluminescence displayed n...

Abstract The understanding of the dynamics a glass above its devitrification temperature remains incomplete. Here, we build spatio-temporal map relaxation highly stable into supercooled liquid using real-time atomic force microscopy imaging. This methodology enables direct visualization progression phase and clarifies quantifies presence localized fast mobility regions separated by giant length...

The feasibility of using a focused ion beam (FIB) for the purpose of thinning vitreously frozen biological specimens for transmission electron microscopy (TEM) was explored. A concern was whether heat transfer beyond the direct ion interaction layer might devitrify the ice. To test this possibility, we milled vitreously frozen water on a standard TEM grid with a 30-keV Ga(+) beam, and cryo-tran...
