in this paper we report synthesis of fe2tio5-5a zeolite (z5a) nanocomposites with 5%, 10% and 20% weight percent of fe2tio5 in 5a zeolite in stearic acid media after calcination of the gel samples obtained at 600-900°c for 2 hrs. the powder x-ray diffraction (xrd) patterns have been used for characterization of the prepared samples. the scanning electron microscopy (sem) images and x-ray energy...

Effects of finite-temperature quasiparticle self-energy corrections on x-ray absorption spectra are investigated within the local density $GW$ approximation up to temperatures $T$ order Fermi temperature. To facilitate calculations, we parametrize using low-order polynomial fits. We show that temperature-driven decrease in electron lifetime substantially broadens near-edge region with increasin...
