This work has assessed factors affecting crystallization of copper sulfide (CuS) under batch conditions and in fed-batch fluidized bed reactor (FBR) using calcium-coated sands as a seed material. Compared with using sodium sulfide nonahydrate as a sulfidation reagent, larger CuS crystals were pr...

Exploring proper anode hosts with stable and ultrafast sodium storage capability is a big challenge for commercializing sodium ion batteries. And tin-based sulfides are considered as ideal anode material for sodium ion batteries because of the high theoretical capacity, while its practical appli...

In copper-gold flotation plants, pyrite which is depressed in copper flotation is often floated subsequently with the addition of sodium sulfide (Na2S) to recover the associated gold. For the first time, this study investigated the role of Na2S responsible for the flotation of pyrite depressed i...

Transition metal sulfides (TMS) are considered as anode candidates for sodium-ion batteries (SIBs) due to the high theoretical specific capacity and natural abundance. Herein, Co3S4@1T MoS2/NC-L hierarchical nanosheets, in which bimetallic sulfides are integrated into N-doped carbon, has been de...

Glioblastoma (GBM) has a poor prognosis despite intensive treatment with surgery and chemoradiotherapy. Previous studies using dose-escalated radiotherapy have demonstrated improved survival; however, increased rates of radionecrosis have limited its use. Development of radiosensitizers could im...

The paper presents the comparative adsorption ability of precipitated barium sulphate and dicalcium phosphate for ferri/ferrous impurities found in commercial grade sodium sulphide. The author had carried out experiments on the usage of precipitated barium sulphate and dicalcium phosphate as an ...

Keratin was extracted from different segments of disposable waste chicken feathers (CF) including the whole feathers, calamus/rachis (β-sheet) and barbs/barbules (α-helix), using sodium sulfide and l-cysteine. The yield of extracted keratin from sodium sulfide and l-cysteine was ˜88% and ˜66% ...

The effect of sodium persulfate (PS) and hydrogen peroxide (HP) pretreatment on granular activated carbon (GAC) was investigated with regard to surface properties, metal impregnation, and application to As(V) adsorption. PS pretreatment at pH 12 and 50 °C destroyed the GAC pore structures but i...

In present work, the treatment of aromatic compounds of simulated wastewater was performed by Fenton and NaOCl/Fe2+ processes. The model solution was prepared based on the wastewater composition of Diisocyanate unit of Karoon Petrochemical Company/Iran containing Diamino-toluenes, Nitro-phenol, ...

The hypergolic ignition of a solid hydrocarbon fuel with hydrogen peroxide has been achieved by embedding catalyst particles into the fuel. Sodium borohydride can enhance ignition of the solid fuel upon contact with 90% hydrogen peroxide. Ignition delay times were measured in drop-on-solid tests...

SummaryBackgroundNew technologies for automated disinfection have been developed, including the use of hydrogen peroxide atomized by specific equipment, with associated silver compounds.

Aluminium hydroxide precipitation from synthetic sodium aluminate solution was studied in the presence of hydrazine or hydrogen peroxide. The addition of low concentration of hydrazine is found to be effective, while higher amount of hydrogen peroxide is required to generate similar effect. XRD ...

The vegetative cells and spores of Geobacillus spp. and Anoxybacillus flavithermus were subjected to 20 kHz ultrasound with a power ∼8 W. Ultrasonication had considerable effect on vegetative cells (5-log reduction in Geobacillus spp. and 1.6-log reduction in A.flavithermus). TEM imaging of the...

Peroxide-modified sodium titanate is synthesized by a coprecipitation method that uses titanium isopropoxide and sodium hydroxide precursors, with hydrogen peroxide as a mineralizer to modify the titanate to enhance actinide sorption. The mechanism and microstructure of the peroxide-modified tit...

The aim of this study was to examine effects of sodium pyruvate on viability as well as on synthesis of reactive oxygen species (ROS), lipid peroxidation and DNA integrity of cryopreserved bovine sperm. In each of 23 Simmental AI bulls three ejaculates were collected. In a split sample design ej...

IntroductionInternal bleaching of discolored teeth uses sodium perborate reacting with water to form the active agent, hydrogen peroxide (H2O2). Sodium perborate is replaced at varying time intervals depending on clinician preference and until esthetically acceptable results are achieved, but th...

A protocol based on peroxide fusion has been developed for the determination of Au in metallurgical samples and ores covering a wide range of concentrations and diverse mineralogies. The quantity of Na2O2 required was minimised, while maintaining lixiviant efficacy, by the use of mixed NaOH + Na...

Zinc nitride films were deposited by reactive radio-frequency magnetron sputtering using a zinc target in a nitrogen and argon plasma. The deposited films were annealed in either air or O2 at 300 °C to investigate the annealing effect on the microstructure, optical properties, and electronic ch...

The current investigation deals about the preparation of porous graphitic carbon nitride (g-C3N4/GCN) nanosheets and fabrication of zinc antimonate (ZnSb2O6/ZSO) nanorods integrated porous g-C3N4 nanosheets to study their electrochemical performance as electrode materials for supercapacitors.
