Nowadays, there is a rising urge to develop and implement cheaper, abundant, environmentally friendly semiconducting materials into practical devices.
Zn(CF 3 COO) 2 promotes the dual reduction of anions to fluoride and sulfide, forming an amorphous hybrid solid electrolyte interface (SEI). This SEI significantly benefits plating/stripping Zn anode thereby improves battery performance.
In this work tungsten disulphide nanostructures loaded with platinum-oxide (PtO), or palladium-oxide (PdO) were grown directly onto alumina substrates. This was achieved using a combination of aerosol-assisted chemical vapour deposition (AA-CVD) method atmospheric pressure CVD technique. At first, oxide nanowires either PtO PdO nanoparticles successfully co-deposited via AA-CVD followed by sulfurization at 900 °C in the next step. The morphological, structural, and characteristics...
Electrocatalytic hydrogenation (ECH) approaches under ambient temperature and pressure offer significant potential advantages over thermal processes but require highly active efficient electrocatalysts. The performance of such electrocatalysts strongly depends not only on the phase also architecture surface chemistry support material. Herein, Pd nanoparticles supported a nickel metal–organic framework (MOF), Ni-MOF-74, are prepared, their activity toward ECH benzaldehyde (BZH) in 3 M acetate...
The potential energy surfaces (PES) of a series gold–boron clusters with formula Au n B ( = 1–8) and m 2 1–7) have been explored using modified stochastic search algorithm.

Randomly oriented ZnO nanowires were grown directly onto alumina substrates having platinum interdigitated screen-printed electrodes via the chemical vapor deposition method using Au as catalyst. Three different film thicknesses (i.e., 3, 6 or 12 nm) used in growth of nanowires, and their gas sensing properties studied for ethanol NO2 reducing oxidizing species, respectively. employing nm thick layers less defective showed most stable, repeatable properties. Despite thickest reached highest...
Abstract Rechargeable aqueous Zn–MnO 2 batteries are attracting attention as a cost‐effective and safe energy storage solution, but their commercialization faces challenges due to limited stability, output voltage, density. Herein, hybrid‐ion system with enhanced Mn 4+ /Mn 2+ electrochemical contribution is introduced using an Al 3+ ‐based electrolyte. Compared conventional Zn electrolytes, the hybrid /Zn cell offers higher voltage of 1.75 V, capacities up 469 mAh g −1 , outstanding...
The SiOx anode exhibits a high specific capacity and commendable durability for lithium-ion batteries (LIBs). However, its practical application is hindered by significant volumetric fluctuations during lithiation/delithiation, alongside metastable nature, which induces mechanical instability irreversible lithium consumption, ultimately impairing long-term retention in full-battery cell configurations. In this study, we present phase-engineering approach designed to improve the structural...
Basic methanolysis of a sterically hindered aminobis(S-arylthiocarbamate) affords novel aminobis(thiophenolate) pincer-type ligand NS22–; the in situ generated dianion reacts cleanly with Ni2+ and Zn2+ resulting dimeric complexes bridging thiophenolate ligands, as determined spectroscopically by X-ray crystallography. The C2-symmetric [Ni(NS2)]2 dimer (1) has square planar coordination geometry around ions, while [Zn(NS2)]2 analogue (2) is characterized distorted tetrahedral each independent...
We report the synthesis of ZnO nanowires by a catalyst‐free vapor‐transport process on SiO 2 /Si substrates. A modification method was performed using small nanoparticles (∼5 nm) in low concentration suspensions. The use dichloromethane or toluene suspensions influences nanoparticle distribution over surface. obtained have diameters ranging from 20 to 100 nm and lengths 0.5 1 µm. Raman scattering results show narrow (∼7 cm −1 ) full width at half maximum E high optical phonon mode, which...

Herein, we investigate the effect of Sn in Ni nanoparticles for GOR formic acid (FA). Electrochemical results show that maximum activity is related amount Ni, as sites are responsible catalyzing via NiOOH/Ni(OH)
Abstract Tri‐ and dithioethers tris(2‐ tert ‐butyl‐4‐methylphenylthiomethyl)amine ( 1 ), bis(2,4‐dimethylphenylthio)methane 2 bis(2‐ ‐butyl‐4‐methylphenylthio)methane 3 ) were developed to evaluate their coordination properties toward Cu + .

Abstract A series of Cu + complexes with ligands that feature varying numbers benzimidazole/thioether donors and methylene or ethylene linkers between the central nitrogen atom thioether sulfur atoms have been spectroscopically electrochemically characterized. Cyclic voltammetry measurements indicated highest 2+ /Cu redox potentials correspond to sulfur‐rich coordination environments, values decreasing as are replaced by nitrogen‐donating benzimidazoles. Both were studied DFT. Their...
The potentially tridentate ligand bis[(1-methyl-2-benzimidazolyl)ethyl]amine (2BB) was employed to prepare copper complexes [(2BB)CuI]OTf and [(2BB)CuII(H2O)2](OTf)2 as bioinspired models of lytic polysaccharide copper-dependent monooxygenase (LPMO) enzymes. Solid-state characterization revealed a Cu(I) center with T-shaped coordination environment metric parameters in the range those observed reduced LPMOs. Solution indicates that [(2BB)CuII(H2O)2]2+ is main species from pH 4 7.5; above...
Recently, it was demonstrated that ZnO thin films sputtered under oxygen-rich atmospheres exhibit localized structural disorder with a significant impact on their physical properties due to the presence of high energetic ions in plasma. Here, highly disordered have been realized simply by using metallic Zn target deposition atmosphere pure oxygen (O2). The results XRD and Raman spectroscopy show defects induced during crystallize wurtzite-type structure. In addition, theoretical DFT...
