Li7P2S8I, an amorphous solid state elecrolyte reveals an increase in Li+ ion conductivity when tempered.The increase in conductivity of 0.8 mS/cm (room temperature) up to 4.6 mS/cm is shown with impedance spectroscopy [1]. The tempering temperature (180°C) is 10°C lower than the melting temperature.
Despite not overcoming the melting temperature, the x-ray diffraction pattern reveals a...
The Swedish Materials Science beamline (SMS) located at the PETRA III synchrotron storage ring (DESY Hamburg, DE) is dedicated to materials research using high-energy X-rays. The beamline consists of an inline branch (P21.2) and a side branch (P21.1), which are operated in parallel and are optimized for a combination of techniques and broad band diffraction, respectively. The inline branch...
The angular resolution in the case of angular dispersive X-ray (XRD) diffraction in transmission geometry is significantly influenced by parameters such as the size (cross-section) and divergence of the photon beam, its degree of monochromaticity, the dimensions, geometry of the sample, and the arrangement of the experiment. This work focuses on characterizing the angular resolution of the...
Polymer electrolyte fuel cells (PEFCs) consist of a gas diffusion layer (GDL) and an electrode on each side, and a polymer electrolyte membrane (MEA) between the electrodes. The main components of the MEA are catalysts, electrolyte membranes and electrodes. In this study, the local atomic structures of catalytic nanoparticles in MEA were investigated by high-energy X-ray diffraction and...
We performed reverse Monte Carlo (RMC) modeling of B2O3 glass based on high-energy X-ray total scattering data. In the B2O3 glass, the so-called boroxol rings are fromed, which are the main structural unit of the glass. Previous studies [1-3] have performed computational modeling of the three-dimensional structure of B2O3 glass, but it was difficult to achieved the expected ratio of boroxol...
In structure analysis of condensed matter by way of X-ray scattering experiments
precise treatment of background intensity is usually negligible so long as crystals
are probed, as their structure information is concentrated in sharp, highly intense
Bragg-reflexes. In less ordered systems such as liquids, glasses and amorphous
solids in general these sharp reflexes are absent and the...
Introduction
In recent years, the development of the Internet of Things (loT) has made our lives more convenient, while the power consumption of semiconductors has increased rapidly. To solve this problem, the semiconductors research has conducted to save energy through miniaturization, but new thin-film semiconductor materials are required for further expansion. Amorphous In2O3 thin films...
