Nucleic acids have become a powerful tool in nanotechnology because of their conformational polymorphism. However, lack of a medium in which nucleic acid structures exhibit long-term stability has been a bottleneck. Ionic liquids (ILs) are potential solvents in the nanotechnology field. Hydrated ILs, such as choline dihydrogen phosphate (choline dhp) and deep eutectic solvent (DES) prepared fro...

Eutectic mixtures of urea and a range of quaternary ammonium salts are liquid at ambient temperatures and have interesting solvent properties.

The Fischer indole synthesis occurs in high yield with one equivalent of the ionic liquid choline chloride[middle dot]2ZnCl(2); exclusive formation of 2,3-disubstituted indoles is observed in the reaction of alkyl methyl ketones, and the products readily sublime directly from the ionic liquid.

Deep eutectic solvents (DES) have recently been postulated as possible environments where protein structure may be preserved in the absence of water. Here we present our results towards understanding protein conformation in choline chloride-based DES and mixtures with water. Lysozyme and bovine serum albumin have been investigated by means of circular dichroism and small-angle neutron scattering.

Three natural deep eutectic solvents (NADES; choline chloride (CC): lactic acid (LA), CC: oxalic (OA), urea (U)) in the ratio 1:2 were tested as a pretreatment of apple pomace prior to hot water extraction pectin. The duration and temperature (for 0.5–2h, at 40–80 °C) was adjusted limit cell wall polysaccharides losses degradation. Extraction yields sugar composition used evaluate impact on pec...

Chlormequat is a quaternary ammonium and choline chlorinated derivated is used as plant growth regulating agent. There are very few documented cases of poisoning in humans. We reported a case of non-fatal suicide attempt by chlormequat in France. A 34-year-old woman was admitted to hospital after deliberate consumption of plant growth regulator, C5 SUN, containing chlormequat chloride (460 g/L)...

One-pot four-component synthesis of polyfunctionalized 1,4-dihydropyridine derivatives was developed by a condensation of aldehydes, malononitrile, diethylacetylenedicarboxylate and aniline in the presence of choline chloride/urea as a deep eutectic solvent (DES)at room temperature.Moreover, an efficient method was reported for the synthesis of highly substituted 4H-chromenes through one-...

The increased demand for portable electronic devices and electric vehicles has resulted in an exponential increase lithium-ion battery (LIB) waste, becoming turn important secondary source critical metals. Electrowinning is a commonly used method to recover base precious metals from solution, which can also be valuable spent LIBs. This study unveiled the cobalt electrochemical recovery using mo...

Hydrogenation of sugars to alcohols is prime interest for food applications instance. Xylose obtained from the hemicellulose fraction lignocellulosic biomass can be hydrogenated xylitol. Herein, we conducted catalytic hydrogenation reactions in a non-conventional media approach by using choline chloride, non-toxic naturally occurring organic compound that form deep eutectic solvent with xylose....

A new direct method for the measurement of red cell lithium was compared with the indirect method. Good correlation (r = 0.97) was found and the coefficients of variation of the direct and indirect methods were 3.9% and 5.5%, respectively. In the direct method red cells suspended in choline chloride were centrifuged through dibutyl phthalate, which removes plasma adherent to the cells. A haemol...
