The origin of the boson peak and thermal conductivity plateau in low-temperature glasses.
We argue that the intrinsic glassy degrees of freedom in amorphous solids giving rise to the thermal conductivity plateau and the "boson peak" in the heat capacity at moderately low temperatures are directly connected to those motions giving rise to the two-level-like excitations seen at still lower temperatures. These degrees of freedom can be thought of as strongly anharmonic transitions betw...
متن کاملFemtosecond laser-induced reduction in Eu-doped sodium borate glasses
In this work, we report permanent reduction of Eu to Eu in sodium borate glasses by irradiation of near-infrared femtosecond laser. Glass composition of sodium borate was 85B2O3–15Na2O. The glasses were doped with 0.05, 0.1, and 0.5mol% Eu2O3. Absorption and fluorescence dynamics were studied to investigate valence state change of europium ions and the energy transfer between Eu and Eu ions. As...
متن کاملThe glass transition temperature of silicate and borate glasses
The dependence of the glass transition temperature on silicate composition as well as on borate composition is discussed. Some new experimental results on borosilicate glass-enamels are put together with the existing literature data. It is demonstrated that in the glass transition interval the activation energy E(Tg) for viscous flow is related to the glass transition temperature. The activatio...
متن کاملLow-temperature thermal conductivity of polyimide irradiated with Ni ions
The planned International Facility for Antiproton and Ion Research (FAIR) will consist of a superconducting double-ring synchrotron offering ion beams of intensity increased by a factor of 100-1000 compared to the existing GSI accelerators. Materials close to the beam tube will be exposed to secondary radiation of neutrons, protons, and heavier particles, possibly limiting reliable function and...
متن کاملLow Temperature Glasses
TWRS wastes contain certain chemical components which, either because of their limited solubility or volatilization at high temperatures, present problems for conventional vitrification technologies. The current task completed by BNL concerns the use of low temperature glasses for tank waste remediation. A literature review of existing technologies highlighted lead-iron-phosphate glasses, with ...
