complex lattice for the following initial conditions: all the crystal atoms are at the lattice nodes; the two semibounded parts of the crystal obtained by dividing the latter by an arbitrary crystal plane have velocities normal to this plane which are equal in magnitude but opposite in direction...
The formation of an interstitial atom in graphite crystals is simulated by the molecular dynamic method, in which the characteristic point is that the effect of covalent bonds in hexagonal lattices is taken into account as the non-central force interaction. It is found that the interstitial atom ...
These movies show that the diffraction patterns repeat themselves along the propagation direction after a regular distance away from the exit plane, following the theory of Talbot effect45. This regular distance is widely known as Talbot length and given by \(Z=2({d}^{2}/{{\it{{\lambda }...
Following elasticity theory, longitudinal and torsional waves are non-dispersive in the long-wavelength limit, whereas flexural waves have distinctive quadratic dispersion46. Furthermore, as the longitudinal mode is not activated in the transverse-pump scheme, the torsional mode can be assigned to the...
Fluoride–ion batteries are a promising alternative to lithium–ion batteries with higher theoretical capacities and working voltages, but they have experienced limited success due to the poor ionic conductivities of known electrolytes and electrodes. Here, we report a high-throughput computational screenin...

The X-ray photoelectron spectroscopy (XPS) spectra shown in Figures S19 and S20 also reveal the presence of all elements (Ni, O, N, C, and S) and that O comes from the coordinated H2O and free H2O molecules in crystal lattices. Thermogravimetric analysis (TGA) of the three complexes ...

It is commonly believed that vitrification is a result of extreme difficulty in crystal nucleation and growth, during which thermodynamics is also crucial. According to Adam-Gibbs theory41, the dynamics correlates strongly with configurational entropy, which is controlled by structural evolution. To ...
