In this study, a novel anatase/graphene (0D/2D)-based composite photocatalyst is synthesized through a facile hydrothemal method using graphene oxide (GO), titanium sulfate (Ti(SO4)2) and hydrazine hydrate (N2H4·H2O) as precursors. The study reveals that the surface-dispersed anatase nanopartic...

Vanadate solutions as ‘metavanadate’ (containing ortho and metavanadate species) and ‘decavanadate’ (containing manly decameric species) (5 mM; 1 mg/kg) were injected intraperitoneously in Halobatrachus didactylus (toadfish), in order to evaluate the contribution of decameric vanadate specie...

The behaviour of CdCo3-V2O5 (1:1) mixture in a saturated water-vapour atmosphere, has been studied at room temperature by means of X-ray diffraction (XRD), infrared spectroscopy (IR) and thermal analysis (TG) and (DSC). The results showed a dramatic change in V2O5 crystalline structure due to ad...

The cost of materials is one of main obstacles for the development of thermochemical energy storage. Compared with traditional inorganic salt hydrates, a mineral named ettringite can easily overcome this limit thanks to its large resource from cementitious materials. Meanwhile, possession of hig...

By mixing different molar concentrations of V2O5 and CdO as reactants, and using the melt-quenching method, an evolution from crystalline vanadate compounds to amorphous materials was produced. For chemical compositions with high mol% of V2O5, crystalline phases with the sequence V2O5, CdV2O6, a...

Pyro-vanadate of cadmium has been obtained at 150°C from both CdCO3-V2O5 (2:1) and CdCO3-NH4VO3 (1:1) mixtures, which were heated in a saturated water-vapour atmosphere. In this way, reactivity of V2O5 strongly increased due to the acid sites formed on the surface by means of adsorption process...

Cadmium and two vanadate solutions as ‘metavanadate’ (containing ortho and metavanadate species) and ‘decavanadate’ (containing decameric species) (5 mM) were injected intraperitoneously in Halobatrachus didactylus (Lusitanian toadfish), in order to evaluate the effects of cadmium and oligom...

The yttrium-bismuth alloy system was studied using microscopic, X-ray, thermal, and chemical analyses. An inverted peritectic reaction develops as a result of bismuth additions lowering the 1475 °C transformation temperature of yttrium to 1460 °C. Eutectic reactions occur at 18.5 at.% Bi and 1...

Thermodynamic properties of Ho–Bi intermediate phases (HoBi and Ho5Bi3) have been studied by means of calorimetric and tensimetric techniques. The heats of formation at T=298 K were determined by high temperature direct synthesis calorimetry and the molar heat capacity of HoBi was measured by d...

For Riemannian manifolds with a smooth measure (M,g,e−fdvg), we prove a generalized Myers compactness theorem when Bakry–Emery Ricci tensor is bounded from below and f is bounded.

In this paper, we present new almost Schur type inequalities for weighted manifolds, under constraints on k-Bakry-Emery Ricci tensor. We also address results for weighted manifolds with convex boundary. The main tools for these results are a Pohozaev-Schoen type identity to weighted manifolds an...

In-situ neutron diffraction was utilized to study the influence of Y-doping on the crystal structure, oxygen non-stoichiometry, and oxygen anion transport pathways in Sr1−xYxCoO3−δ at temperatures and oxygen partial pressures typical of SOFC cathode conditions, from 500 °C to 800 °C, and oxyg...

For practical application in syngas production, the oxygen permeable membranes should possess both high oxygen permeation flux and good stability in harsh environment (CO2-containing reductive atmosphere). Under the premise of keeping stability, anion-doping method was applied to improve the oxy...

Pt is the benchmark oxygen reduction reaction (ORR) catalyst for the anion exchange membrane fuel cells. In this paper, we have done systematic studies on the influence of anions (F−, Cl−, Br−, I−, CO32−, SO42−, SO32− and S2−) to the ORR activity and durability of Pt/C in alkaline condition. It ...

The pursuit of superb aqueous Zn-ion batteries (ZIBs) has driven the focus on solving their cathode limit. This study provides a readily accessible approach toward designing high-capacity ZnMn2O4 cathode by extracting oxygen anions. Experimental and computational results revealed the electronic ...

Sulfur‒containing anions are expected to exist in molecular clouds and other astrochemical environments due to the relative abundance of sulfur and the predicted stability of the anions. Furthermore, nitrogen and oxygen atoms are of high abundance in the interstellar medium. Therefore, reactions...

Two new organic-inorganic compounds [H2NC(N(CH3)2)2]4[Mo8O26]·2H2O (1) and (C6H11NH3)4[Mo8O26] (2) have been synthesized at room temperature and characterized by single-cristal X-ray diffraction, thermal and elemental analyses. We show that the β-[Mo8O26]4− isomer can be stabilized by counteri...

Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis. EAE is mainly mediated by adaptive and innate immune responses that leads to an inflammatory demyelization and axonal damage. The aim of the present research was to examine the therapeutic efficacy of D-asp...

The design, synthesis, and evaluation of a series of novel inhibitors of aspartate transcarbamoylase (ATCase) are reported. Several submicromolar phosphorus-containing inhibitors are described, but all-carboxylate compounds are inactive. Compounds were synthesized to probe the postulated cyclic ...

Canavan disease is a fatal neurological disorder caused by defects in the metabolism of N-acetyl-l-aspartate (NAA). Recent work has shown that the devastating symptoms of this disorder are correlated with the elevated levels of NAA observed in these patients, caused as a consequence of the inabi...
