In this paper, we have examined the effect of ammonium and imidazolium based ionic liquids (ILs) on the stability and activity of proteolytic enzyme α-chymotrypsin (CT) in the presence of cold atmospheric pressure plasma jet (APPJ). The present work aims to illustrate the state of art implementing the combined action of ILs and APPJ on the enzyme stability and activity. Our circular dichroism (...

Ionosilica ionogels have been lately introduced as emerging all-ionic designer materials. They consist of an ionic liquid (IL) guest trapped within a solid ionosilica support host. In this work, we investigate the influence (i) nature and (ii) ionosilica/IL ratio on mobility confined IL. We report elaboration various via nonhydrolytic sol–gel process, using namely tris(3-(trimethoxysilyl)propyl...

Trihexyltetradecylphosphonium (P6,6,6,14) salts of luminescent anionic Pt(II) complexes, (P6,6,6,14)[PtX2(ppy)] (X = Cl-, Br-; ppy 2-phenylpyridinate), are synthesized and photofunctional thin films with crystal/liquid bi-stability fabricated. In particular, the chloride complex provides a film exhibiting thermo- mechano-triggered luminescence ON/OFF switching at ambient temperature, which is b...

Quaternary ammonium and phosphonium salts have been screened for their toxic effect on HeLa and K562 cancer cell lines, as well as on normal HUVEC cells. Tri-n-butyl-n-hexadecylphosphonium bromide, the first phosphonium salt with a halogen anion tested against HeLa cells, was 12 times more potent (IC50 <5 μm after 24 and 48 h) than the clinically used reference compound cisplatin and 17 times m...

Adenylosuccinate synthetase has been purified more than 250-fold from extracts of rabbit muscle acetone powder by heating to 60”, ammonium sulfate fractionation, phosphocellulose and hydroxylapatite chromatography, and Sephadex G-150 gel filtration. Crystals have been obtained by dialysis against 60 to 67% ammonium sulfate. Enzyme activity is stable for about 2 weeks in phosphate buffer contain...

The ammonia leaching method for treating low-grade rhodochrosite has the advantages of a good impurity removal effect and low environmental pollution. In this paper, aiming at efficiency treated by method, studies on enhancing manganese using ammonium hydrogen fluoride as an additive are carried out. effects different concentrations, temperatures, times, liquid-solid ratios, stirring rates, add...

Optimizing crop N uptake while minimizing NH3 volatilization from fertilizer sources is a critical part of agricultural best management practices. Urea the most widely used but also one susceptible to losses as NH3. Fertilizer and additives can be reduce volatilization. Specifically, urease inhibitors [e.g., N-(n-butyl) thiophosphoric triamide (NBPT)] urea. A novel fused ammonium sulfate nitrat...
