Very different materials are named "Glass," with Young's modulus (E) and Poisson's ratio (v) extending from 5 to 180 GPa and from 0.1 to 0.4, respectively, in the case of bulk inorganic glasses. Although glasses have in common the lack of long-range order in the atomic organization, ...
29Si magic angle spinning-nuclear magnetic resonance (MAS-NMR) was performed on these glasses to examine the short-range order about the silicon atoms. In this paper, the resultant chemical shift data of these glass families were combined and examined in the light of various models derived from...
The short-range order of multicomponent glasses in the diopside–orthoclase–apatite system with different contents of the initial components is investigated by X-ray diffraction upon heat treatments at different temperatures. It is found that the short-range order parameters change considerably when the...
Short-Range Order refers to the atomic arrangement observed on a surface, such as the (111) surface of Pt 38 Ni 62, as depicted in Monte-Carlo simulations and corresponding STM images. AI generated definition based on: Surface Science Reports, 2000 ...
The short range order of multicomponent SeO2 glasses has been studied by neutron scattering. To identify the contribution of SeO2 different oxides, MoO3, V2O5, Bi2O3 were used for glass synthesis. Crystal like model distribution functions were calculated in order to describe the experimental RDFs...
We extend the usual static view of short range order in metallic glasses to a dynamical model of local order. We use an atomistic simulation of a NiZr glass to investigate time-dependent fluctuations of the atomic environment. We show that, even in the "frozen" glass, the solute-centered ...
31P solid-state NMR studies of the short-range order in phosphorus–selenium glasses 来自 Semantic Scholar 喜欢 0 阅读量: 29 作者:A Bytchkov,F Fayon,D Massiot,L Hennet,DL Price 摘要: The local structure of P-rich and Se-rich phosphorus–selenium glasses was studied using high-resolution...
Properties such as refractive index8, conductance/resistivity9, magnetic sus- ceptibility10, hardness11 and the glass transition temperature12 of amorphous films are known to change signifi- cantly with thickness. Thus, amorphous materials can be induced to exhibit a wider range of properties in ...
For this reason, we investigated the structure of some GexGaxTe100-2x glasses by combining X-ray and neutron diffraction data with Ge- and Ga K-edge EXAFS measurements in the framework of the reverse Monte Carlo simulation technique. Short range order parameters of Ge-Ga-Te glasses are ...
