Measurements of the low-energy electronic structure in Gd2PdSi3 and Tb2PdSi3 by means of angle-resolved photoelectron spectroscopy reveal a Fermi surface consisting of an electron barrel at the Gamma point surrounded by spindle-shaped electron pockets originating from the same band. The calculated momentum-dependent RKKY coupling strength is peaked at the 1/2GammaK wave vector, which coincides ...
cd1-xmnxs (x = 0, 0.1, 0.2) nanoparticles, prepared by co-precipitation method under ultrasonic irradiation, were studied by means of x-ray diffraction, scanning electron microscopy, ftir and uv-vis spectroscopy measurements. the average particle size of nanoparticles from the scanning electron microscopy image is about 20-30 nm. results show that partial substitution of cd by mn leads to a re...
in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....
