Oxidation reactions are an important part of the synthetic organic chemist's toolkit and continued advancements have, in many cases, resulted in high yields and selectivities. This review aims to give an overview of the current state-of-the-art in oxygenation reactions using both chemical and enzymatic processes, the design principles applied to date and a possible future in the direction of hy...

Biochar is a solid material formed from the carbonization of biomass. result conversion organic waste by using incomplete combustion method with limited oxygen supply (pyrolysis). Meanwhile, rubber scrap production crumb has not been utilized much other than as mixture fertilizer in soil. This study aims to analyze effectiveness biochar peat water filtration media and effect thickness on remova...

The aim of this study was to evaluate the combination two ethylene removal methods and temperature on post-harvest quality peaches. For purpose, filters with potassium permanganate (KMnO4) lamps emitting ultraviolet light (UV) were mounted machines which enabled air movement in conservation chambers, facilitating by KMnO4 photocatalysis simultaneously. This system used at temperatures, 1 °C 25 ...

the preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. the nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from kmno4 and cocl2 with respectively source at room-temperature. the structure and surface morphology of the obtained manganese oxide were studied by mea...

The epigenetic DNA modifications 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in eukaryotes are recognized either in the context of double-stranded DNA (e.g., by the methyl-CpG binding domain of MeCP2), or in the flipped-out state (e.g., by the SRA domain of UHRF1). The SRA-like domains and the base-flipping mechanism for 5(h)mC recognition are also shared by the recently discovere...

Siderite (FeCO3) is commonly found in coal overburden and, when present, can cause interference in the determination of neutralization potential (NP). Under acidic testing conditions, FeCO3 reacts to neutralize acid, which contributes to the NP. However, continued weathering of FeCO3 (oxidation of Fe 21 and hydrolysis of Fe) produces a neutral to slightly acidic solution. The effects of hydroge...

an essential characteristic for high performance inherently hydrophobic membranes such as microporous high density polyethylene (hdpe) membranes is to have a hydrophilic surface. in this project, wet chemical functionalization as a facile and effective method was developed to give a hydrophilic property to hdpe membranes using polar functional groups. kclo3, k2cr2o7 and kmno4 were selected as o...

background and purpose: phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. in this study, an activated carbon of miswak’s root (mr) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. materials and methods: adsorption experiments were then conduct...

Potassium permanganate (KMnO4 ) is a powerful oxidising agent. In its raw form, it an odourless, sweet-tasting, dark-purple substance, available in ready-to-use solutions, pellets, tablets, crystals and powder form. clinical practice historically, has been used as antiseptic antifungal rural South African communities, however, KMnO4 many traditional uses, including use snake repellent, treatmen...

Abstract Tetracycline (TC) is widely used in the livestock industry, but undigested TC excreted with waste and accumulates environment. In this study, swine manure-derived biochar (SBC) was modified KMnO4 (MnOx-SBC), to remove TC. SEM-EDS, FTIR, XPS elemental analysis all indicated that ultrafine MnOx particles were attached surface. The surface properties composition of oxygen-containing funct...
