Redox flow batteries (RFBs) are promising choices for stationary electric energy storage. Nevertheless, commercialization is impeded by high-cost electrolyte and membrane materials. Here, we report a low-cost all-iron RFB that features inexpensive FeSO4 electrolytes, microporous along with glass fiber separator. The addition of 0.1 м 1-ethyl-3-methylimidazolium chloride (EMIC) overcomes the low...

The organic component is the most abundant fraction of atmospheric submicron particles, while the formation mechanisms of secondary organic aerosol (SOA) are not fully understood. The effects of sulfate seed aerosols on SOA formation were investigated with a series of experiments carried out using a 9 m3 smog chamber. The presence of FeSO4 or Fe2(SO4)3 seed aerosols decreased SOA yields and inc...

Oxidative stress has been identified as one of the factors that affects fertility status. Therefore, this study sought to investigate the inhibitory effect of aqueous extract of Moringa oleifera and Newbuoldia laevis leaves on FeSO4 and Sodium Nitroprusside (SNP) induced lipid peroxidation in rat testes in vitro. Incubation of the testes tissue homogenate in the presence of FeSO4 and SNP caused...

The effects on the lactic acid (LA) production by thermophile Lactobacillus bulgaricus ATTC 11842 on whey as a basal medium of seven factors namely, temperature °C, pH, Lactose g/l, Yeast extract g/l, corn steep liquor (CSL) g/l, K2HPO4 g/l, and salts g/l (MnSO4, MgSO4 and FeSO4) were investigated, through the statistical analysis of the results by Plackett and Burmann experimental design. pH w...

Various indispensable metabolic processes are reliant on minute amounts of essential trace elements i.e., Fe and Cu and on FeCu association as well to maintain normal health. An excess of both elements can render abnormality in liver function. The aim of this work was to evaluate the acute hepatotoxicity of Fe & Cu by analyzing the biochemical functions of liver. Adult male Wistar rats (200g) w...

Imbalance between matrix metalloproteinases (MMPs) and tissue inhibitor of matrix metalloproteinases (TIMPs) is an important control point in tissue remodelling. Several findings have reported a marked MMP/TIMP imbalance in a variety of in vitro models in which oxidative stress was induced. Since previous studies showed that commercial hyaluronan and chondroitin-4-sulphate are able to limit lip...

This study is concerned with the optimization of fermentation parameters for the hyper production of mannanase from Fusarium oxysporum SS-25 employing two step statistical strategy and kinetic characterization of crude enzyme preparation. The Plackett-Burman design used to screen out the important factors in the culture medium revealed 20% (w/w) wheat bran, 2% (w/w) each of potato peels, soyabe...

Hydrogen peroxide (H2O2) and Cu(OAc)2 or FeSO4 (Fenton type reagents) perform heparin (Hep) depolymerisation to low-molecular-weight heparin (LMWH) following a radical chain mechanism. Hydroxyl (OH) radicals which are initially generated from H2O2 reduction by transition metal ions abstract hydrogen atoms on the heparin chain providing carbon centred radicals whose decay leads to the depolymeri...
