Nodes and edges constitute crystal structures, so crystal structures are easy to express as graphs. Using graph networks to predict material properties has been a prevailing view in the past years. Neural networks are used to fit the density functional theory (DFT) calculation results to predict the properties of various materials. Based on this train of thought, the authors develop graph neural network models for predicting material properties with crystal structure data, and the model gets com...

Synthesis of a class of Lx-β-NiMoO4 (L = None, Al, V, Fe, Co) nanocomposites by a facile one-step solid-state route at 700, 800, and 900 °C for 8 h is introduced in the present study. The physical and electrochemical properties of the fabricated compounds are studied by X-ray powder diffraction (XRPD), field-emission scanning electron microscope, energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, UV-vis, vibrating sampling magnetometer (VSM), and cyclic voltammetry (C...

A numerical study of dislocation density is carried out by 3D and time-dependent analysis using the Alexander–Haasen model to estimate growth direction dependence of plastic deformation of Al2O3 single crystals during the annealing process. The direction of crystal growth is set to c-, a-, and m-axes. The calculated results show distribution of dislocation density in the crystal grown in the c-axis has a sixfold symmetry while those in the crystals grown in the a- and m-axes show asymmetric dist...

Herein, AgMn alloys are prepared by the pulsed laser welding technique in an argon atmosphere. The effect of the laser pulses width and stoichiometric composition of the alloys on the structural, compositional, morphological, and electrical properties are investigated. In contrast to the traditional preparation techniques which reveal cubic structure of AgMn alloys, the pulsed laser welding technique reveals the orthorhombic phase of the alloys. The lattice parameters of the orthorhombic phase o...
