An oxygen-rich energetic compound, 1,3-bis(trinitromethyl)-1,2,4-triazole (13), was obtained by a two-step nitration and found to have an excellent crystal density of 1.90 g/cm3 confirmed by X-ray single-crystal diffraction. This highly dense materia

The green bodies with two different packing structures (lower and higher density) were prepared from cubic zirconia nano-particles. The sintering trajectories during densification of normal and two-step sintering (TSS) were studied to obtain nanocrys

Mobile components of dynamic river systems are varied, and more than fundamental water and sediment interactions must be considered to assess morphodynamic changes. Here, the effects of instream wood and plastic accumulations on the riverbed are mode
