The world is currently in the midst of a climate crises and many across globe are competing to find new technologies create clean, effective ways harnessing renewable energy sources. However, this needs be stored current systems simply would not last. Zinc-ion batteries (ZIBs) with vanadium-containing cathodes recently arising technology providing cheap, safe, eco-friendly alternative systems. ...

In the present study, Fe3O4 super paramagnetic nanoparticles were synthesized via co-precipitation of Fe3+ and Fe2+ chloride salts in the presence of ammonia Solution. The product was characterized by Fourier Transform Infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), and zeta–potential particle size distributing methods. The synt...

The ability of cholinergic agonists to activate phospholipase C in bovine adrenal chromaffin cells was examined by assaying the production of inositol phosphates in cells prelabeled with [3H]inositol. We found that both nicotinic and muscarinic agonists increased the accumulation of [3H]inositol phosphates (mainly inositol monophosphate) and that the effects mediated by the two types of recepto...

The level of inositol phosphates was measured in rat hepatocytes treated with 2-methyl-1,4-naphthoquinone (menadione) or tert-butyl hydroperoxide, which cause Ca2+ mobilization from intracellular stores and an increase in cytosolic free Ca2+ concentration. Although neither agent produced any apparent changes in the resting level of inositol phosphates, pretreatment of hepatocytes with either me...

N,N-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. Styrene was first polymerized. Then, sulfonation reaction was performed by H2SO4 (c) followed by chlorination with POCl3 obtain chlorosulfonated polystyrene. Amidification reaction was then applied to get sulfonamide resin. Sulfonamide resin was treat...

In this study, the techno-economic analysis of lignocellulosic biomass conversion to electricity in a small scale power plant was conducted. The proposed process is based on the thermal pathway of electricity production from a carbon content feed. Woods, forest and agricultural residues were considered as the biomass feed, which are available extensively in Iran. Besides, the process benefits n...

Polyprenyl phosphates, as well as polyprenyl alcohols bearing different isopentenyl C(5) units, have been synthesized. The pH range of spontaneous vesicle formation of polyprenyl phosphates with or without polyprenyl alcohols was defined by fluorescence microscopy. A variety of the acyclic or monocyclic polyprenyl phosphates studied formed stable vesicles in water over a wide range of pHs, and ...

Extensive application of silica nanoparticles (SNPs) in various industrial products has led to the development of silica extraction methodologies out of various waste products. Rice husk is an agricultural waste with a high content of amorphous silica. However, the presence of metal ion impurities and unburned carbon in the rice husk content may present an adverse effect on product color and pu...
