Single-crystalline niobium oxide fluoride (Nb(3)O(7)F) hierarchical nanostructures are firstly prepared via a facile hydrothermal method without using any template or surfactant. The results of scanning electron microscopy and transmission electron microscopy showed that the hierarchical morphology of Nb(3)O(7)F could be effectively controlled by adjusting the reaction time. Ultraviolet-visible...

Abstract Gradualizing System F has been widely discussed. A big challenge is to preserve relational parametricity and/or the gradual guarantee. Most past work focused on preservation of parametricity, but often without few recent works satisfy both properties by giving up syntax, or with some restrictions and introduction sophisticated mechanisms in dynamic semantics. While important for polymo...

Recently synthesized industrially significant perovskites Cs3Cu2X5 (X=Cl,Br,I) are subjected to a density functional theory (DFT) investigation utilizing the CASTEP code. This study explores various physical features, including structural, optical, thermodynamic, elastic, mechanical, and electronic properties. There is strong correlation between optimized structure parameters existing experimen...

Three newly designed pyrochlore oxides, Eu2Tm2O7 (Tm = Hf, Sn, Zr), are analyzed for their magnetic, optical and electronic properties using ab-initio calculations within the context of density functional theory (DFT). We can refer these compounds as direct bandgap materials because there is a very slight difference between height bands at Γ- M-point. It observed that engineering be performed b...

Prediction of new materials is crucial for the advancement technology. Here, in this research work, first-principle computation has been conducted utilizing WIEN2K package to probe structural, electronic, mechanical, and optical properties barium-based chloroperovskites BaMCl3 (M = Ag, Cu) compounds. The optimized lattice constants are calculated both compounds which 9.90 Bohr BaAgCl3 9.38 BaCu...

Using density functional theory-based first-principles simulations, detailed physical properties of the tetragonal phase alkali metal halide Rb2NbCl6 under pressure were explored for first time. The structural, mechanical, and thermodynamic stability confirmed by Born requirements negative values formation energy. analysis Pugh’s Poisson’s ratios Cauchy’s reveals that is ductile pressures in co...

Tryptophan 2,3-dioxygenase (TDO) is a first and rate-limiting enzyme for the kynurenine pathway of tryptophan metabolism. Using Tdo-/mice, we have recently shown that TDO plays a pivotal role in systemic tryptophan metabolism and brain serotonin synthesis as well as emotional status and adult neurogenesis. However, the expression of TDO in the brain has not yet been well characterized, in contr...

Abstract Hexakis (m-phenylene ethynylene) (m-PE) macrocycles, with aromatic backbones and multiple hydrogen-bonding side chains, had a very high propensity to self-assemble via H-bond π–π stacking interactions form nanotubular structures defined inner pores. Such of rigid macrocycles is leading novel applications that enable the researchers explored mass transport in sub-nanometer scale. Herein...
