Partial annealing of a coupled mean-field spin-glass model with an embedded pattern [PDF]

open access: yes, 2010
A partially annealed mean-field spin-glass model with a locally embedded pattern is studied. The model consists of two dynamical variables, spins and interactions, that are in contact with thermal baths at temperatures T_S and T_J, respectively.

Study Of The Chemical Durability And Hazardous Ionic Leaching Of(Soda-Lime) Glass [PDF]

open access: yesEngineering and Technology Journal, 2009
Huge amounts of glass materials being applied in medical, pharmaceuticaland chemical aqueous solutions; this requires the study of chemical stability of glass at the exposed surfaces with these solutions where the leaching takes place.

Annealing glasses by cyclic shear deformation

open access: yesThe Journal of Chemical Physics, 2022
A major challenge in simulating glassy systems is the ability to generate configurations that may be found in equilibrium at sufficiently low temperatures, in order to probe static and dynamic behavior close to the glass transition. A variety of approaches have recently explored ways of surmounting this obstacle.

Quantum versus classical annealing: insights from scaling theory and results for spin glasses on 3-regular graphs [PDF]

open access: yes, 2015
We discuss an Ising spin glass where each $S=1/2$ spin is coupled antiferromagnetically to three other spins (3-regular graphs). Inducing quantum fluctuations by a time-dependent transverse field, we use out-of-equilibrium quantum Monte Carlo simulations

Timescales of crystallization and viscous flow of the bulk glass-forming Zr-Ti-Ni-Cu-Be alloys [PDF]

open access: yes, 2003
Crystallization behavior and equilibrium viscosity of a series of alloys in the Zr-Ti-Cu-Ni-Be system are studied using multiple techniques to determine the various contributions to glass-forming ability.

Strong emission in Yb3+/Er3+ co-doped phosphate glass ceramics

open access: yesResults in Physics, 2017
Yb3+/Er3+ co-doped phosphate glass and glass ceramics were prepared by high-temperature melting method. The X-ray diffraction, transmission electron micrographs, up-conversion and infrared emissions, photothermal conversion properties of the samples have

Nanoindentation of Nanoglasses Tested by Molecular Dynamics Simulations: Influence of Structural Relaxation and Chemical Segregation on the Mechanical Response

open access: yesFrontiers in Materials, 2021
We present molecular dynamics simulations of nanoindentation in order to investigate the effects of segregation and structural relaxation on the mechanical properties of Cu64Zr36 nanoglasses prepared by particle consolidation and long-time annealing. Our

Residual stress relaxation and microstructure in ZnO thin films [PDF]

open access: yes, 2006
Stability under normal environmental conditions over a long period of time is crucial for sustainable thin-film device performance. Pure ZnO films with thicknesses in the 140 - 450 nm range were deposited on amorphous glass microscope slides and (100 ...

Definition of the strain-stress distribution of porous glass in the retarded cooling temperature range

open access: yesMATEC Web of Conferences, 2017
The estimation of the strain-stress distribution (SSD) of porous glass (foamed slag glass, FSG) is assessed by annealing temperature curves according to the given values of the thermomechanical and thermophysical properties of porous glass, which are in ...
