1. Solid state NMR of multiple-spin systems
Sammanfattning : Many nuclear magnetic resonance (NMR) experiments subject the nuclear spins to time-periodic modulations, for example, mechanical sample rotation and irradiation by periodic radio-frequency pulse sequences. An efficient simulation algorithm (COMPUTE) has been proposed for calculating NMR spectra from such systems. LÄS MER
2. Structure-Property-Composition Correlations in Rare-Earth Alumino-silicate Glasses
Sammanfattning : Rare earth (RE) alumino-silicate (AS) glasses exhibit favorable physical, mechanical and optical properties, such as high values of the glass transition temperature, Vickers hardness, and refractive index. RE2O3-Al2O3-SiO2 glasses have found several industrial applications, for example as components of optical amplifiers and lasers. LÄS MER
3. Structure of Rare-Earth Aluminosilicate Glasses Probed by Solid-State NMR Spectroscopy and Quantum Chemical Calculations
Sammanfattning : Aluminosilicate glasses incorporating rare earth elements feature highly beneficial physical and chemical properties, at the level beyond that accessible for compositions based on alkali and/or alkaline earth metals. Extraordinary hardness, high glass transition temperatures and indices of refraction, favorable coefficients of thermal expansion, as well as excellent chemical durability, result in many potential technological applications.
