The application of ionic liquids as environmentally benign reaction solvents for synthesis and catalysis has received extensive recent attention. In this regard we have developed ionic liquids based on the cheap and readily available components choline chloride (ChCl; HOCH2CH2N(Me)3?Cl) and zinc chloride as alternatives to the more commonly employed alkyl imidazolium-aluminium chloride mixtures...

Phosphorus (P) availability is commonly assumed to limit productivity in many tropical soils, yet there relatively little information on the phosphorus chemical forms, distribution, and transformations that P acid soil. The best way obtain of separate fractions soil using series solvents different strength sequential analysis. method used was Chang Jackson Formation forms their binding largely ...

Deep eutectic solvents (DESs) is a newly developed green solvent with low cost, easy preparation and regeneration. Because of its excellent solubility swelling effect in lignocellulose, it has received widespread attention recognition. In this study, choline-based deep (DESs)—choline chloride-urea (CC-U), choline chloride-ethylene glycol (CC-EG), chloride-glycerol (CC-G), chloride-lactic acid (...

Protein-solvent interactions govern the behaviors of proteins isolated from extreme halophiles. In this work, we compared the solvent envelopes of two orthologous tetrameric malate dehydrogenases (MalDHs) from halophilic and non-halophilic bacteria. The crystal structure of the MalDH from the non-halophilic bacterium Chloroflexus aurantiacus (Ca MalDH) solved, de novo, at 1.7 Å resolution exhib...

oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...

Bio-based and biodegradable polymers are essential for a sustainable society. Cellulose is the most abundant biopolymer on earth; however, derivatization necessary its processing, which slows down biodegradability dramatically, e.g. used cigarette filters made from cellulose acetate barely biodegradable. We developed first reversible modification of cellulose, allows processing guarantees full ...

• Separation and recovery of electrolyte spent EV Lithium-Ion batteries. Optimum process temperature time determined to be 130°C for 80 minutes. On-line exhaust gas analysis by In-Situ FT-IR. Toxic LiPF 6 decomposition products HF POF 3 detected. Electrolyte is seldomly considered in state-of-art battery recycling methods but rather evaporates decomposes uncontrolled during the pre-treatment st...

Natural products have gained worldwide favor due to their sustainable and ayurvedic nature. In this study, rose containing anthocyanin was explored as a source of yellowish–pink natural colorant for wool dyeing using various solvents (aqueous, alkaline, acidic, basified methanol). Dyeing performed by optimizing the following parameters: pH, temperature, time, salt concentration. It observed tha...
