The development of metal-free bifunctional electrocatalysts for hydrogen and oxygen evolution reactions (HER OER) is significant but rarely demonstrated. Porous organic polymers (POPs) with well-defined electroactive functionalities show superior performance in reaction (HER) (OER). Precise control the active sites' local environment requires careful modulation linkers through judicious selection building units. Here, a systematic strategy introduced modulating functionality to design...
Abstract The development of electricity‐driven oxygen evolution reaction (OER) is a potent solution for energy storage applications. In recent years, there surge in interest designing transition metal‐based catalysts with stable linkages, presenting an efficient alternative to noble electrocatalysts. Transition metal complexes linked by salen ligands garner considerable attention due their capacity chelate and stabilize ions. This work presents novel approach strategically incorporating the...
Photocatalytic activity of TiO2 (anatase) is appreciably enhanced by substitutional doping Mo in anatase lattice, conjunction with the incorporation nanostructured MoO3 within parent lattice. The photocatalyst material was characterized detail using X-ray diffraction, Raman spectroscopy, diffuse reflectance (DR-UV–Vis spectroscopy), photoelectron and electron microscopy. Photocatalysis experiments were conducted a model rhodamine-B (Rh–B) dye reaction both UV visible irradiation sources....
Six new binary charge-transfer (CT) cocrystals have been synthesized by solvent drop-assisted mechanochemical grinding method, and all of them exhibited remarkable color changes during the process. Crystal structure analysis reveals donor (D) acceptor (A) molecules assembled primarily via cofacial π···π stacking interactions displaying mixed D–A–D–A stacked columns. Interestingly these very diverse dielectric response in presence an alternating current (ac) external electric field, their...
Abstract Herein, synthesis of novel barium silicate glasses doped with La 2 O 3 in the system (30-x)BaCO –30TiO –40SiO -xLa , BTSL (0 ≤ x 6) via fast melt-quenching technique was carried out. Further, to confirm amorphous behaviour prepared glass samples, x-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) were The density all determined using Archimedes’ principle found be an increasing manner. To investigate doping influence on glasses, few more physical...
A general approach for enhancing sensitivity of nuclear magnetic resonance sideband separation experiments, such as Two-Dimensional One Pulse (TOP), Magic-Angle Turning (MAT), and Phase Adjust Spinning Sidebands (PASS) with phase incremented echo-train acquisition (PIETA) is described. This applicable whenever strong inhomogeneous broadenings dominate the unmodulated frequency resonances, in non-crystalline solids or samples large residual anisotropy. PIETA provides significant enhancements...
Understanding the role of V 2 O 5 within borosilicate glass matrices is important for development novel toward immobilization sulfate containing high‐level nuclear wastes. Present investigation shows, sodium barium matrix can be homogeneously added up to mol% and beyond which it separates out into three phases, example, (i) silica (ii) Barium (Ba) – Vanadium (V) oxide, (iii) matrix. 29 Si MAS NMR (Nuclear Magnetic Resonance) studies samples show that below addition, silicate network...
A new two-dimensional Nuclear Magnetic Resonance (NMR) experiment to separate and correlate the first-order quadrupolar chemical/paramagnetic shift interactions is described. This experiment, which we call shifting-d echo allows a more precise determination of tensor principal components values their relative orientation. It designed using recently introduced symmetry pathway concept. comparison with earlier proposed methods presented experimentally illustrated in case 2H (I = 1)...
The structure and dynamics of itraconazole were investigated by 13C 2DPASS MAS SSNMR spin-lattice relaxation time measurement to get an insight into its multiple biological activities, e.g., antifungal, antiviral, anticancer etc. molecular correlation at chemically different sites carbon nuclei was calculated considering that the mechanism is mainly dominated chemical shift anisotropy interaction heteronuclear dipole-dipole interaction. long for C35, C6, C5, C34 participated in 1, 2,...
