A series of (Ce, Cr)xO2/Nb2O5 catalysts with different (Ce, Cr)xO2 to Nb2O5 mass ratios were synthesized by the deposition-precipitation method for use in deep catalytic oxidation of 1,2-dichloroethane (DCE), which is one of the typical chlorinated volatile organic compound pollutants. The textu...

Volatile chlorinated hydrocarbons (VCHs) are often found as a type of persistent and ubiquitous contaminant in groundwater. The feasibility, characteristics and microbial mechanism of acclimation of biodiversity-rich inoculation source for bioelectrochemical stimulated VCH dechlorination remain ...

Arsenic is a major water contaminant, threat to human health and country’s economy. Arsenic can occur in different oxidation states (−3, 0, +3 and +5) out of which arsenite (As3+) and arsenate (As5+) are highly toxic. Identification and quantification of such toxicant has become a major challen...

In the cancer microenvironment, extracellular communication allows various types of cells to coordinate and execute biological functions. Emerging evidence indicates that exosomes, as mediators of cell communication, are involved in tumor progression. Little is known, however, about the mechanis...

Herein, we report noble metal free, cathodically co-electroreduced rGO/MnO2 nanohybrid (NH) on glassy carbon electrodes for arsenite (As (III)) detection in water by square wave anodic stripping voltammetry (SWASV). Cyclic voltammetry, scaning electron microscopy, X-ray diffraction, trasnsmissio...

In this study, arsenic trioxide (ATO) was encapsulated in liposomes via copper acetate (Cu(OAc)2) gradients and high entrapment efficiency of over 80% was obtained. The average particle size and the zeta-potential of the liposomes were detected to be 115.1 ± 29.1 nm and −21.97 ± 0.6 mV, respec...

A novel multifunctional sorbent material of nano-titanium dioxide-enabled chitosan beads cross-linked with copper (CuTICB) is capable of photo-oxidation of As(III) to the less-toxic and more easily adsorbed As(V) in UV light and selective adsorption of arsenite (As(III)) and arsenate (As(V)) in ...

The effects of varying carbon ions (C+) implantation energies on Aluminum Carbide (Al4C3) precipitation, surface morphology and electrochemical corrosion resistance of aluminum (Al) were evaluated. The Al samples were implanted with C+ of different energies of 0.25, 0.5, 1, 2, and 4 MeV at a con...

This study deals with the investigation on mechanical properties of aluminium alloy (AA 6082) composites reinforced with tungsten carbide particles. Stir casting process was employed to fabricate the aluminium composite specimen by varying tungsten carbide in 2, 4, 6, 8 and 10% by weight. The co...

The interface plays a vital role in determining the microstructure and mechanical properties of metal matrix composites. The interfacial reactant, aluminum carbide (Al4C3), has a great influence on the mechanical properties of carbon nanomaterials reinforced aluminum matrix composites (C/Al). Ho...

Bastnäsite is the main ore mineral in many carbonatite-related rare earth element (REE) deposits, which account for ∼51% of rare-earth oxide reserves worldwide. However, the occurrence, geochemistry, and genetic significance of bastnäsite has not been methodically investigated. The Cenozoic Mia...

Bastnäsite is an important mineral resource in the production of rare earth materials and is usually beneficiated by flotation. The flotation of bastnäsite is problematic due to the competitive adsorption of hydroxamate collector on bastnäsite and its associated calcium-bearing gangue minerals s...

Multilayer fullerenes (carbon nano-onions [CNOs]) have recently attracted important research interest because of their high chemical stability that allows the encapsulation of specific materials of interest and their protection from the external environment. Until now, CNOs have been filled with...

Efforts to generate Ln2+ precursors suitable for reduction to Ln1+ compounds have provided the X-ray crystal structures of Cp″2Sm, 1-Sm, and Cptt2Ln, 2-Ln [Ln = Eu, Sm; Cp″ = C5H3(SiMe3)2; Cptt = C5H3(CMe3)2], allowing direct comparisons of these similar cyclopentadienyl rings in Ln2+ complexe...

Scandium (Sc) doped GaN layers (GaN:Sc) were grown on SiN treated sapphire substrate by atmospheric pressure metal–organic vapor phase epitaxy (AP-MOVPE) using Tris(cyclopentadienyl)scandium (Cp3Sc) as a scandium precursor. Standard growth conditions of GaN were used with varying Cp3Sc flow rat...

Tris(cyclopentadienyl)scandium ScCp3 was isolated in Ar-matrices (20 K) and the structure of monomeric ScCp3 was studied using infrared spectrometry. When compared with the spectra and results of density functional calculations, the matrix-isolated ScCp3 was found to have a structure where all t...

Reactions of [Ni0(COD)2] (COD = 1,5-cyclooctadiene) with meta-chloroperoxybenzoic acid, phenyl-N-tosylimidoiodinane or 2-(tert-butylsulfonyl)iodosylbenzene were performed in THF solution in the presence of one equivalent of tris(3,5-dimethylpyrazol-1-yl)methane (Tpm∗), yielding the product compl...
