Two modifications of a modern theory capital structure—the Brusov–Filatova–Orekhova (BFO) theory—with variable income are considered: (1) with the tax payments at end periods and (2) advance payments. BFO formulas for WACC, company capitalization, V, were derived these two cases. Using obtained formulas, dependence weighted average cost capital, WACC; discount rate; WACC–g (here, g, is growth r...

The thin-film heterostructures or nanocomposites exhibit vastly different properties from those observed in bulk systems. Herein, a nanocomposite of reduced graphene oxide (RGO) and BiFeO3 (BFO), the remnant ferroelectric polarization is found to follow nonmonotonic magnetic field dependence at room temperature as applied swept across 0–20 kOe on pristine sample. Bulk BiFeO3, contrast, exhibits...

Abstract Photocatalytic degradation of organic pollutants is great significance for wastewater remediation but still hindered by the poor catalytic efficiency catalysts. Herein, we report a strategy to simultaneously introduce piezocatalysis and enhance intrinsic photocatalysis in single catalyst, which improved performance methylene blue (MB) significantly. Specifically, piezoelectric BiFeO 3 ...

We report on the fabrication of sub-20 nm BiFeO3 (BFO) nanoparticles using a solid-state approach and preferential leching process. The were subsequently used to deposit, through spray pyrolysis, BFO thin films in rhombohedral (R3c) crystallographic structure. Then, systematic investigations optical photocatalytic properties conducted determine effects particles size, microstructure increased s...

Abstract The dynamic contribution of domain walls (DWs) to application‐relevant dielectric and piezoelectric properties ferroelectrics relaxor‐based oxide ceramics has been in the focus since earliest studies on these complex multifunctional materials. Despite vital importance DWs material design for targeted applications, understanding interfaces significantly advanced only recently owing conc...

The Brusov–Filatova–Orekhova (BFO) theory is generalized for the simultaneous account of variable company profit and advance tax on income payments. BFO formula WACC, has been derived. dependence discount rate, WACC–g (here g growth rate), capitalization, V, equity cost, ke, leverage L at various values g, debt kd, age company, n, studied. It shown, that no longer a rate. This role passes to WA...

A highly structured description of entities and events in histories can support flexible exploration of those histories by users and, ultimately, support full-text digital libraries. Here, we apply the Basic Formal Ontology (BFO) to structure a passage about the Roman Constitution from Gibbon’s Decline and Fall of the Roman Empire. Specifically, we consider the specification of Roles such as Co...
