A new organic stilbazolium derivative crystal 2-[2-(3-hydroxy-4-methoxy-phenyl)-vinyl]-1-methyl-pyridinium naphthalene-2-sulfonate dehydrate (C<sub>25</sub>H<sub>23</sub>NO<sub>5</sub>S·2H<sub>2</sub>O) (VSNS) was synthesized successfully.
High-performance thin-film transistors (TFTs) are the fundamental building blocks in realizing potential applications of next-generation displays. Atomically controlled superlattice structures expected to induce advanced electric and optical performance due two-dimensional electron gas system, resulting high-electron mobility transistors. Here, we have utilized a semiconductor/insulator channel structure comprising ZnO/Al2O3 layers realize high-performance TFTs. The TFT with ZnO (5 nm)/Al2O3...
Transition metal sulfides (TMS) exhibit proliferated edge sites, facile electrode kinetics, and improved intrinsic electrical conductivity, which demand low potential requirements for total water splitting application. Here, we have propounded copper sulfide-coupled cobalt sulfide nanosheets grown on 3D nickel as an electrocatalyst hydrogen (HER) oxygen evolution (OER) reactions. The formation of djurleite with a Cu vacancy enables faster H+ ion transport shows HER activity remarkably lower...
Single-crystalline, nanostructured dendrites, single and double-layered snowflakes of hematite (α-Fe2O3) were synthesized by a well controlled, surfactant-assisted hydrothermal reaction K3[Fe(CN)6]. By varying the preparatory conditions such as precursor concentration type surfactant, we could establish precise control on morphology sample. X-Ray diffraction, Raman analysis X-ray photoelectron spectroscopic studies have confirmed that grown morphologies hematite. Dendrites obtained due to...
Single-crystalline porous hematite nanorods and spindle-like nanostructures were successfully synthesized by a low temperature reflux condensation method. Two different iron sources, namely, FeCl3?6H2O Fe(NO3)3?9H2O, hydrolyzed in the presence of urea to selectively prepare nanostructures. Initially, akagenite phase was obtained refluxing precursor for 12?h then as-prepared transformed upon calcination at 300??C 1?h. The shape aspect ratio refluxed sample retained even after this shows...
High aspect ratio molybdenum trioxide (MoO3) nanorods grown along the [100] direction were successively synthesized by a simple hydrothermal method. We used sodium molybdate and hydrochloric acid as starting materials from their reaction we obtained MoO3 of high ratio. The dimensions found to be uniform in size, with well-defined boundaries. intercalation an organic molecule (pyrazine) into these has resulted single-crystalline microstructures, change length breadth few orders. Pyrazine...
Abstract Organic‐inorganic lead halide perovskite phases segregate (and their structures degrade) under illumination, exhibiting a poor stability with hysteresis and producing accumulation at the surface.In this work, we observed structural interfacial dissociation in methylammonium iodide (CH 3 NH PbI ) perovskites even dark vacuum conditions. Here, investigate origin consequences of self‐degradation CH stored vacuum. Diffraction photoelectron spectroscopic studies reveal into 2 , which...
A simple hydrothermal method is utilized to synthesize iron-doped tin oxide nanoparticles (Fe-SnO 2 NPs) at various doping concentrations. The structural characterization using XRD, Raman, and FTIR measurements confirmed the incorporation of Fe ions into SnO lattice without any deviation in tetragonal crystal system nanoparticles. SEM HRTEM images show spherical-shaped with agglomeration. values interplanar spacing ([Formula: see text]-value) calculated from are consistent XRD results....
Stoichiometric tungsten oxide (WO(3)) nanorods are synthesized on (W) substrates by a high-temperature, catalyst-free, physical deposition process and subsequent annealing in oxygen atmosphere. Tungsten grown thermal evaporation of WO(3) powder at elevated temperature tube furnace. XRD, TEM XPS analysis shows that the as-grown single crystalline non-stoichiometric (WO(x)). Annealing WO(x) 700 °C under atmosphere has led to formation stoichiometric as evidenced Raman analysis.
Water soluble methionine functionalized CdTe quantum dots (QDs) and CdTe/ZnS core–shell QD samples have been prepared by a reflux condensation method used to detect explosive chemicals, such as dinitrotoluene (DNT), nitrotoluene (NT) nitrobenzene (NB) in liquid media. Meisenheimer complex formation between the surface attached aromatic molecules has helped them selectively via fluorescent quenching process. Fluorescence occurred because of transfer excited electrons from molecules. Depending...
