Gamma Irradiation-Induced Discoloration and Annealing Characteristics of K9 Glass

open access: yesPhotonics
K9 glass is prone to developing color center defects under gamma irradiation, which exhibit strong absorption at specific laser wavelengths. However, most of these color centers exhibit an annealing phenomenon in natural environmental conditions, wherein

Structure-dynamics relationships in cryogenically deformed bulk metallic glass

open access: yesNature Communications, 2022
Understanding of the atomic-scale mechanisms of rejuvenation of bulk metallic glass still remains unclear. Here, using configurational entropy derived from X-ray experiments, authors show a clear picture of the relaxation process during annealing of a ...

Optical properties of annealed As30Te67Ga3 thin films grown by thermal evaporation [PDF]

open access: yesProcessing and Application of Ceramics, 2018
Chalcogenide glasses have received lots of attention because of their superior optical properties. To optimize these properties and expand areas of applications, more studies are required to establish the extent to which the parameters can be tuned over ...

Inductive flash-annealing of bulk metallic glasses [PDF]

open access: yesScientific Reports, 2017
AbstractWe developed a temperature-controlled inductive flash-annealing device, which heats bulk metallic glasses (BMGs) at defined rates of up to 200 K/s to a given temperature. Subsequent instantaneous quenching in water allows preserving the microstructures obtained at various stages of crystallization.

Plasmonic molecules via glass annealing in hydrogen [PDF]

open access: yesNanoscale Research Letters, 2014
Abstract Growth of self-assembled metal nanoislands on the surface of silver ion-exchanged glasses via their thermal processing in hydrogen followed by out-diffusion of neutral silver is studied. The combination of thermal poling of the ion-exchanged glass with structured electrode and silver out-diffusion was used for simple formation of ...

Possible Ergodic-nonergodic regions in the quantum Sherrington-Kirkpatrick spin glass model and quantum annealing

open access: yes, 2018
We explore the behavior of order parameter distribution of quantum Sherrington-Kirkpatrick model in the spin glass phase using Monte Carlo technique for the effective Suzuki-Trotter Hamil- tonian at finite temperatures and that at zero temperature ...
