Natural siderite (FeCO3 ), simulated synthetic siderite and nZVI/FeCO3 composite were used as green and easily available iron-based catalysts in peroxydisulfate activation for remediating 2-chlorophenol as the target contaminated and this technique can effectively degrade organic pollutants in...

Organohalogen compounds (OHCs) are widely present and have been shown to have harmful effects on both humans and wildlife. Pet cats are mainly exposed to anthropogenic and naturally occurring OHCs through dietary intake of cat food and ingestion of contaminated house dust. In this study, we...

Use of bacterial biochar for Cr(VI) removal opens room for new research in terms of cost effectiveness, better performance and high selectivity. This work reports the synthesis, physicochemical characterization and performance evaluation of bacterial biochar synthesized at 200oC and 400oC. To...

The paper analyses the impact of futures contracts on weak form of Efficient Market Hypothesis on the Pakistan Stock Exchange (PSX). The current study uses ten years data of 18 companies, which offer futures contact, and 58 firms which do not offer futures contracts over the period from January...

Fifteen diterpene derivatives including seven new ones, sinensisins A−G ( 1 , 2 , 4 , 7 , 10 , 14 , 15 ), were obtained from the leaves and twigs of Aphanamixis sinensis . Their structures were elucidated by NMR spectroscopic and ECD data analyses. These diverse carbon skeletons containing...

Seven new 2-(2-Phenethyl) chromone derivatives ( 1-7 ), including four 2-(2-Phenethyl) chromone s ( 1-4 ), one 6, 7, 8 trihydroxy-2-(2-Phenethyl) chromone ( 5 ), one acetylated 5, 6, 7, 8-tetrahydroxy-2-(2-Phenethyl) chromone ( 6 ), and one chlorine-containing 5, 6, 7,...

Three new oxygenated cyclohexene derivatives, pandensenol D - F ( 1-3 ), two new flavanoids, pandensone A and B ( 4 - 5 ), and seven known compounds ( 6-12 ) were isolated from the methanol extract of the leaves of Uvaria pandensis Verdc. (Annonaceae). The structures were characterized by NMR...

A multiscale approach is presented here to investigate the effect of the ferrite-pearlite microstructure after annealing on the subsequent machining process of steel gears. The case-hardening steel 18CrNiMo7-6 and a cost efficient alternative with reduced Cr and Ni content have been studied....

The Small Punch (SP) and Shear Punch (ShP) tests are established mechanical test approaches that have found application in several industrial sectors for material ranking and mechanical property estimation, particularly where more conventional test approaches are inhibited such as when...

In this study, a new fenton system combined with electro-fenton and bio-eletro-fenton (EF-BEF system) was proposed for the ENR degradation and swine wastewater treatment, and the pitaya peel derived carbon modified by sulfidized nanoscale zerovalent iron (SnZVI) was developed as catalyst of the...
