Abstract. Deep eutectic solvents (DESs) are novel green with great potential in many industrial applications. Due to their high tunability, DESs can be synthesized and prepared into various concentrations by dilution water. This work revolutionises the determination of selected DESs’ water activity using inferencing respective freezing point depression. Using Hildebrand-Scott equation, depressi...

Natural deep eutectic solvents (NADES) made mainly with abundant primary metabolites are being increasingly applied in green chemistry. The advantages of NADES as green solvents have led to their use in novel green products for the food, cosmetics and pharma markets. However, one of the main difficulties encountered in the development of novel products and their quality control arises from thei...

The results of studying the physical properties a deep eutectic solvent based on choline chloride and sulfosalicylic acid have been presented. A phase diagram for this two-component mixture has constructed, dependences its density refractive index temperature studied first time. molar refractivity under study calculated. possibility using as an extractant recovery metal ions in solid–liquid sys...

Choline is involved in relevant neurochemical processes. In particular, it is the precursor and metabolite of acetylcholine (ACh). Choline is an essential component of different membrane phospholipids that are involved in intraneuronal signal transduction. On the other hand, cholinergic precursors are involved in ACh release and carry out a neuroprotective effect based on an anti-inflammatory a...

The first electrochemical series in a deep eutectic solvent (DES) is described. Speciation resulting from the unusual chemistry of the choline chloride based DES is used to explain both similarities and differences from aqueous media. We give examples of how these differences can be exploited in technologically important systems.

The Cover Feature illustrates the distribution of different components aqueous choline chloride solution around hydrophobe methane. hydrogen bonds formed between water molecules, cations, and ions are shown using light yellow dots. preferred orientations with respect to methane at distances from latter quantified in a 2D histogram.

A novel cyclization reaction of ethenetricarboxylate derivative aromatic compounds in the presence of various Lewis acids gave benzo-annulated cyclic compounds such as oxindole and benzofuran derivatives via Friedel-Crafts intramolecular Michael addition in high yields. For example, the reaction of diethyl 2-[(N-methyl-N-phenylcarbamoyl)methylene]malonate (1a) in the presence of ZnCl2 at room t...

Interfacial behavior of selected biologically and technologically relevant ions is studied using molecular dynamics simulations employing polarizable potentials. Propensities of choline, tetraalkylammonium (TAA), and sodium cations, and sulfate and chloride anions for the air/water interface are analyzed by means of density profiles. Affinity of TAA ions for the interface increases with their i...

The aim of this study was to evaluate the degree of conversion (DC%), water sorption (WS), solubility (SO), and resin-dentin bonding stability of experimental adhesive systems containing ZnCl2. Different concentrations (wt.%) of ZnCl2 were added to a model etch-and-rinse adhesive system consisting of BISGMA, HEMA, UDMA, GDMA, water, and ethanol: Zn0 (0%-control group); Zn2 (2%); Zn3.5 (3.5%); a...
