Selenium (Se) is an essential nutrient for animals, humans, and microorganisms, but its role in the plants needs further exploration. It considered beneficial at low levels, toxic higher there a fine boundary between these concentrations. Generally, Se levels less than 1 mg kg−1 have been found to be while cause toxicity most of agricultural crops. At concentrations, can act as plant growth regulator, antioxidant, anti-senescent, abiotic stress modulator, defensive molecule against pathogens...
Developing nonprecious metal-based electrocatalysts with outstanding performance has been the focal point of scientific community for past decade. Multiprinciple element medium- and high-entropy alloys have recently known to exhibit a range superior mechanical, physical, electrocatalytic, anticorrosive properties, which are traditional alloys. In this study, electrocatalytic properties equiatomic single-phase medium-entropy alloy electrodes compositions CoNiCr, CoNiV, CoNi(Cr/V) investigated...
Commercialization of photoelectrochemical (PEC) water-splitting technology is hindered by the slower kinetics oxygen evolution in currently available photoanodes. Light absorption, charge-separation, and charge-transfer efficiencies determine reaction (OER) at semiconductor photoanode surfaces. All these parameters can be maximized nanotexturing surface through morphological (cones, pyramids, grids, etc.) control crystallographic (facets) orientation. The primary objective texturing on...
Ternary oxides/sulfides have long been investigated as promising electrode materials for charge storage applications. However, it is important to rationally design nanostructured hybrid composites superior performance electrodes in devices. In this work, MoO3@NiCo2S4 are synthesized by the hydrothermal method followed annealing at different temperatures. The properties of these tested cyclic voltammetry, galvanostatic charge–discharge curves and electrochemical impedance spectroscopy. It...
Abstract The Fine-tuning of Shear Thickening Fluids (STFs) by surface modification silica particles has fascinated scientist’s interest worldwide as it results in performance enhancement STF based on armor systems. In the current study, modified Silica nanoparticles (average diameter 600 nm) possess thiol functional groups which were attained through a reaction with 3-mercaptopropyl-trimethoxysilane absolute ethanol at 90 °C. thickening fluid Thiol functionalized prepared sonochemical method...
Metal oxides have been used as supports and promoters to enhance the electrocatalytic activity of Pt/C for methanol oxidation reaction (MOR). In this work, Gd 2 O 3 prepared by simple precipitation method (Gd (PC)) polymer-assisted (PL)) is examined support Pt/C.

Abstract Shear thickening fluid (STF) are non-Newtonian fluids that usually behave as liquid in normal condition however under sudden impact, they transformed into a solid like structure with abrupt rise viscosity. The rheological properties of these play significant role energy dissipation. In the present work, effect boric acid (BA) an additive for fine tuning shear (ST) behavior colloidal silica-based (STFs) was investigated. STFs were synthesized silica particles (600 nm) polyethylene...
Amikacin is a widely used aminoglycoside antibiotic effective against various gram-positive and gram-negative microorganisms in veterinary human medicine. In this study, an “on-off” fluorescence nanosensor for highly sensitive determination of amikacin based on carbon quantum dots (CQDs) gold nanoparticles (AuNPs) composite has been developed simple rapid on-site analytical method. This method reduces CQD (turn-off) when they bind to AuNPs but recovers (turn-on) binds releases the CQDs. The...
Directionality of Nanostructured forms TiO 2 prepared through electrochemical anodization as photoanodes in photoelectrochemical (PEC) water splitting benefits the efficient e - and h + separation. However, a large band gap hinders using such nanostructures presence visible light. Doping with metals can be one strategic ways to reduce gaps. In present work, single-step titanium foils viscous electrolyte containing different concentrations indium metal salt is used fabricate Indium-doped...
