Continuous industrial development has increased the demand of energy. Inevitably, energy sources is steadily progressing using various methods. Rather than establishing a new source, system for storing waste heat generated by industry now been accepted as useful strategy. Among such systems, hydration and dehydration reactions MgO/Mg(OH)2 are eco-friendly, have relatively low toxicity risk, large reserves. Therefore, it promising candidate heat-storage system. In this study,...
Abstract In this study, high‐purity and centimeter‐scale bulk Ta 2 Ni 3 Se 8 crystals are obtained by controlling the growth temperature stoichiometric ratio between tantalum, nickel, selenium. It is demonstrated that could be effectively exfoliated into a few chain‐scale nanowires through simple mechanical exfoliation liquid‐phase exfoliation. Also, calculation of electronic band structures confirms semiconducting material with small bandgap. A field‐effect transistor successfully...
The development of a highly efficient catalyst for water splitting and photodegradation organic dyes has become the focus considerable number research groups. In work described here CdZnS@MIL-53(Fe) ZnS@MIL-53(Fe) were synthesized by solvothermal method subjected to thermal degradation at 520 °C in an oxidative environment obtain CdZnS/Fe2O3 ZnS/Fe2O3, respectively. Electrocatalytic activity oxygen evolution reaction is analyzed via cyclic voltammetry linear sweep voltammetry. It was found...
In this study, single-chain atomic crystals (SCACs), Mo3Se3–, which can be uniformly dispersed, with an atomically thin diameter of ∼0.6 nm were modified to disperse in organic solvent. Various surfactants chosen provide steric hindrance aqueous-dispersed Mo3Se3– by modifying the surface Mo3Se3–. The dispersions surface-modified SCACs nonpolar solvent (toluene, benzene, and chloroform) stable a uniform 2 nm, they have enhanced stability from oxidation (>10 days). With that polystyrene tail...
Exposure to ultraviolet (UV) radiation induces many serious health issues. Because of concerns, there is an urgent need develop UV filters with better efficacy and high safety. For this purpose, titanium dioxide (TiO2) nanoparticles are the most desirable materials due their excellent protection abilities. The use TiO2 as sunscreens has raised some concerns about potential risks formation TiO2-mediated free radicals. Herein, have been successfully embedded in silica (SiO2) microspheres using...
Aqueous dispersion of van der Waals bonded one-dimensional materials Mo6S3I6 with hydrophobic surfaces has been studied. The surface charge the dispersed is controlled from negative to positive by type dispersant tail (anionic, SDS and NaDDBS; cationic, CTAB; nonionic, Poloxamer 407), through this, it possible deposit in nanosized electrophoretic deposition at a desired position. When flexible device was manufactured transferring Mo6S3I6, confirmed that electrical conductivity can be...
Abstract In this research, dispersion of a new type one-dimensional inorganic material Nb 2 Se 9 , composed van der Waals bonds, in aqueous solution for bio-application study were studied. To disperse which exhibits hydrophobic properties water, experiments carried out using block copolymer (poloxamer) as dispersant. It was confirmed that PPO, the portion Poloxamer, adsorbed onto surface and PEO, hydrophilic portion, induced steric hinderance to size 10 nm or less. confirm adaptability...
We synthesized ternary composition chalcogenide Ta2NiSe7, a quasi-one-dimensional (Q1D) material with excellent crystallinity. To utilize the electrical conductivity property of breakdown current density (JBD) according to thickness change through mechanical exfoliation was measured. It confirmed that as decreased, maximum voltage (VBD) increased, and at 18 nm thickness, 35 MA cm-2 JBD measured, which times higher than copper, is commonly used an interconnect material. By optimization...
Due to their outstanding performance in valuable electrochemical reactions, transition-metal phosphides (TMPs) have emerged as promising electrocatalysts. The low boiling point of the intermediate reactants was a significant obstacle synthesizing various TMPs. present work describes highly reproducible and cost-effective method for chromium phosphide (CrP) nanoparticles using volatile precursor. We successfully synthesized crystallinity-controllable CrP partially oxidized compound. obtained...
Electrochemical dopamine (DA) detection has been extensively studied for the practical diagnosis of neurological disorders. A major challenge in this system is to synthesize selective and sensitive DA-sensing electrocatalysts extracellular fluids because critical interferents such as uric acid (UA) ascorbic (AA) exhibit oxidation potentials similar that DA. Herein, we report an extremely electrocatalyst DA sensing prepared by vanadium selenide (V2Se9). solution-based process first time was...
Abstract Many attempts have been made to develop applications using the metal‐insulator transition (MIT) phenomenon of VO 2 . However, difference in densities two phases poses serious obstacle for those applications, as it can destroy or disable during phase transformations. For microsized nanosized devices, this aspect be critical. We attempted measure mechanical properties when co‐exist, well an individual phase, via in‐situ control temperature plate‐shaped The lamella structure is formed...
