Thermal, Structural and Crystallization Study of Niobium Potassium Phosphate Glasses [PDF]

open access: yesMaterials Research, 2015
New glass compositions were investigated in the binary system KPO3-Nb2O5. The glass forming domain was determined by melt-quenching of the starting nominal compositions and it has been experimentally observed that glass samples can be obtained between ...

Precipitating tunable-emission CsPb(Cl/Br)3 QDs in boro-germanate glass for wide-color-gamut liquid crystal displays

open access: yesJournal of Information Display, 2019
Embedding CsPbX3 (X = Cl, Br, I) perovskites QDs in inorganic glass matrix via in-situ crystallization has been regarded as a feasible strategy to improve their stability against water, heat, and light irradiation.

A new method to determine open porosity and permeability constants of open-pore sintered glasses by photoacoustic technique Um novo método para determinar a porosidade e as constantes de permeabilidade de filtros vítreos por meio da técnica fotoacústica

open access: yesCerâmica, 2005
The Photoacoustic (PA) technique was used to investigate the structural properties (e.g. open porosity and permeability) of open-pore sintered glasses. This work demonstrates that the photoacoustic signal of open-pore sintered glasses, which are produced

Gaze Tracking System for User Wearing Glasses

open access: yesSensors, 2014
Conventional gaze tracking systems are limited in cases where the user is wearing glasses because the glasses usually produce noise due to reflections caused by the gaze tracker’s lights.

Effects of Glass Transition and Structural Relaxation on Crystal Nucleation: Theoretical Description and Model Analysis

open access: yesEntropy, 2020
In the application of classical nucleation theory (CNT) and all other theoretical models of crystallization of liquids and glasses it is always assumed that nucleation proceeds only after the supercooled liquid or the glass have completed structural ...
