The fast diffusion of alkali ions and resulting high ionic conductivity is a defining feature of alkali borate glasses. Here we report impedance spectroscopy and atomic-scale x-ray photon correlation spectroscopy measurements on rubidium borate syste

To describe chemical ordering in solid solutions systems Warren–Cowley short-range parameters are ordinarily used. However, they are not directly suited for application to long-range ordered systems, as they do not converge to zero for large separa

Many physical properties of glasses are still far from being understood at the atomic level. The lack of experimental methods capable of studying glassy dynamics at this scale has impeded the development of a complete model for atomic transport proce

Applying coherent X-rays by the method of atomic-scale X-ray Photon Correlation Spectroscopy results in beam-induced dynamics in a number of oxide glasses. Here these studies are extended to rubidium and caesium borates with varying alkali contents.

A simple one-pot synthesis of RuO2 nanoparticles by the thermal decomposition of ruthenium nitrosyl nitrate [Ru(NO)(NO3)3] up to 800 °C was investigated. The RuO2 phase was characterized by XRD, SAXS, FE SEM/EDS, Raman, DTA/TGA and FT-IR techniques.

An attempt has been made to clarify the fundamental assumption that the properties of materials change as the crystallite size of the material is reduced below 100 nm. CuFe 2 O 4 samples of different crystallite sizes were prepared by the sol–gel a

We report on the development of structural and magnetic order in epitaxially grown L10 FePt thin films. Upon annealing, the easy axis of magnetization changes from the out-of-plain into the in-plain direction. We found that the overall fraction of re

We report on nuclear resonant scattering (NRS) studies of the electric field gradient (EFG) of a clean Fe monolayer on W(1 1 0) and its changes upon adsorption of residual gases. The consecutive NRS time spectra indicate a gradual tilt of the EFG mai
