Here, we demonstrate an experimental proof of concept for nanofocused x-ray photon correlation spectroscopy, a technique sensitive to nanoscale fluctuations present in broad range systems. The experiment, performed at the NanoMAX beamline MAX IV, uses novel event-based detector capture nanoparticle structural dynamics with microsecond resolution. By varying nanobeam size from σ=88 nm σ=2.5μm, q...
nowadays various methods are presented for synthesis of barium strontium titanate (bst) nanopowders with different morphology and properties. each of these (bst)s has got individual characterization that makes it suitable for a special application. every method has a special quality, causes it to have preference over the other methods. low processing temperature is a desired point which most of...
polyvinylpyrrolidone / nickel oxide (pvp/nio) dielectrics were fabricated with sol-gel method using 0.2 g of pvp at different working temperatures of 80, 150 and 200 ºc. structural properties and surface morphology of the hybrid films were investigated by x-ray diffraction (xrd) and scanning electron microscope (sem) respectively. energy dispersive x-ray spectrosc...
We present resonant inelastic x-ray scattering and x-ray emission spectroscopy results on Gd metal to 113 GPa which suggest Kondo-like aspects in the delocalization of 4f electrons. Analysis of the resonant inelastic x-ray scattering data reveals a prolonged and continuous delocalization with volume throughout the entire pressure range, so that the volume-collapse transition at 59 GPa is only p...
This paper reviews the research in nanomaterials conducted in our laboratory in the last decade using conventional and synchrotron radiation techniques. While preparative and conventional characterisation techniques are described, emphasis is placed on the analysis of nanomaterials using synchrotron radiation. Materials of primary interests are metal nanoparticles and semiconductor nanowires an...
