A quaternary amorphous equiatomic FeCrSiNb HEA thin film was synthesised and characterised with the view for applications in demanding environments. The produced on silica silicon substrates by ion beam sputter deposition. Scanning Electron Microscopy (SEM) used to analyse morphology, Energy-dispersive X-ray spectroscopy (EDX) investigate atomic composition. crystal structure of sample investig...

Niobium-doped nanocrystalline Li4Ti5O12 (LTO) is synthesized by the solid-state reaction method, and influence of dopant concentration (x = 2–10 mol%) on microstructural electrochemical properties studied. The X-ray diffraction Raman patterns assessed cubic spinel structure Li4Ti5−xNbxO12 phase in all samples. Marginal changes lattice parameters, unit cell volume dislocation density LTO are obs...

Artisanal gold mining causes widespread health problems due to illegal exposure hazardous inorganic compounds, such as arsenic (As) and mercury (Hg). The sources prevalence of pollution are strongly influenced by topography, stream dynamics, soil type, land use. In the present study, potential elements (PHEs), absorption abilities nanoparticles (NPs), ultrafine particles (UFPs) were analysed fr...

Abstract The method of pulsed laser ablation in liquids (PLAL) is applied for synthesis composite nanostructures on the basis TiO x and ZnO combined with noble metals like Au, Pt Pd. metallic plate immersed water ablated by nanosecond Nd:YAG irradiation. Its fundamental wavelength fourth harmonic are used, respectively, to produce modify morphology structure nano-objects. procedure consists two...

The tin-doped TiO2 powders obtained by sol-gel and microwave-assisted methods were investigated. synthesis took place in a basic medium (pH 10, ammonium hydroxide, 25%) starting from tetrabutyl orthotitanate its parental alcohol. In the case of dopant, Tin(II) 2-ethylhexanoate as SnO2 precursor was used amount 1, 2, or 4 mol % SnO2. Based on thermal analysis data, thermally treated air, at 500 ...

Selenium nanoparticles (SeNPs) are specific form of this element that has recently become the subject numerous research, especially in field biomedicine. Several synthesis procedures for obtaining SeNPs have been developed so far, among those including reduction selenium salts most frequently used. In work, it is examined effect two stabilizing agents on morphology, size, and crystallinity obta...

Abstract The toxicity of heavy metals in the aquatic environment is a serious challenge to global community. Even at low concentrations, have cumulatively destructive effect on living organisms environment. Biomass wastes been investigated for removal published literature; however, performance and capacity biomass represents drawback towards effective application. Therefore, this study, waste s...

Abstract The corrosion mechanisms and kinetics of a Mg-rich alkali aluminoborosilicate glass simulating UK high-level waste (CaZn28) were investigated upon dissolution in synthetic cement solutions. Dissolution varied as function the different pH alkali/alkaline earth content each solution. High resolution microscopy spectroscopy techniques ascertained nature interface between TEM-EDS revealed ...

Abstract In the study of precipitates in high-Nb non-oriented silicon steel for rotor electric automobiles, it was found that mass dispersed Nb-rich were formed during rolling process steel, these are presumed to be Laves phases published literatures. this regard, two types automobiles and their crystallographic relationship with Fe matrix determined using SAED, FFT IFFT, calculation strength e...

Zirconia (ZrO2), an inorganic material, is a very fascinating material due to its high mechanical strength and fracture toughness. The synthesis carried out by using co-precipitation method optimum content of zirconium oxychloride octahydrate (ZrOCl2.8H2O) with NaOH solution at calcination temperature 700°C. synthesized samples were characterized ensure structural, functional, morphological che...
