The authors observed the surface morphology transition from the atomically flat two dimensional layer-by-layer mode to the three dimensional pyramidal mode of heteroepitaxial PbTiO3 PTO islands synthesized by hydrothermal epitaxy by scanning electron microscopy and atomic force microscopy. Two types of 001 Nb–SrTiO3 NSTO with the same step height, 0.25 and 1 m terrace widths, were used for subs...

Nature evolves structures like honeycombs at optimized performance with limited material. These efficient can be artificially created the collaboration of structural topology optimization and additive manufacturing. However, extensive computation cost causes low mesh resolution, long solving time, rough boundaries that fail to match requirements for meeting growing personal fabrication demands ...

SrIrO3 (SIO) with a perovskite structure exhibits broad application prospects in electronic synapses due to its high carrier mobility, scalability, and compatibility silicon technology. On the other hand, ferroelectric polarization can efficiently directionally regulate movement of carriers, which provides possibility improve synaptic properties such materials. In this study, based on SIO epita...

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...

Abstract The urge for a sustainable and non-polluting industry has raised the need search an alternative insulating fluid that could be used in transformers, because of negative environmental effect mineral-based fluids. Natural esters from non-edible oil seeds showed to feasible alternative, unfortunately they possess poor thermooxidative properties. Neem trees grow nearly on all types soils c...

Most known results on avoiding the occur-check are based notion of "not subject to occur-check" (NSTO). It means that unification is performed only such pairs atoms for which never succeeds in any run a nondeterministic algorithm. Here we show this requirement too strong. We how weaken it, and present some related sufficient conditions under may be safely omitted. examples proposed approach pro...
