We report the preparation and study of properties novel deep eutectic solvents (DESs) formed by zwitterionic trimethylglicine high melting point carboxylic acids. These DESs are liquid at room temperature or temperatures lower than 70 °C do not have chloride any metal ions in their composition. media were characterized terms viscosity, conductivity, density, ionicity (via Walden plots), surface tension thermal stability. The values observed similar to other typical DESs, mixtures resulted...
Preparation, properties and toxicity of room temperature deep eutectic solvents formed by (1<italic>S</italic>)-(+)-10-camphorsulfonic acid aromatic, aliphatic amphiphilic sulfobetaines.
Deep eutectic solvents (DESs) represent a new "green" alternative to classic organic solvents; however, their high viscosity often limits utilization. The physicochemical properties of DESs can be tuned by adding cosolvents, varying the operating temperature, or both, but structure has preserved. In this work, three pure based on choline chloride (ChCl) mixed with diethylene glycol (DEG), triethylene (TEG) polyethylene 200 (PEG 200), as well ChCl/TEG/water mixtures were studied. Particular...
In this study, we explored the use of Deep Eutectic Solvents (DESs) as green and sustainable alternative for synthesis Iron Oxide Nanoparticles (IONs). Six different binary mixtures Hydrogen Bond Acceptors (HBAs) Donors (HBDs) were prepared thoroughly characterized to investigate how their components physicochemical properties influence structure, morphology, magnetic resulting IONs. Additionally, role DESs was assessed using ATR‐MIR spectroscopy, providing insights into HBA‐HBD interactions...
Development of a simple method to efficiently immobilize lipase ensuring its stability and activity in water even at high temperatures.
In the field of stone conservation, removal iron stains is one most challenging issues due to stability and low solubility ferrous species. present paper, three different chitosan-based hydrogels added with acetic, oxalic or citric acids are applied on lithotypes, i.e., granite, travertine marble, widely diffused in monumental heritages, artificially stained by deposition a rust dispersion. The reducing power carboxylic combined good chelating properties chitosan effectively remove from...
Abstract The rate of decarboxylation 6‐nitrobenzisoxazole‐3‐carboxylate ion increases sharply with increasing head group size in a series cetyltrialkylammonium bromides (C 16 H 33 NR 3 Br: R = Me, CTABr; Et, CTEABr; n – Pr, CTPABr; Bu, CTBABr) enhancements 10 2 (CTABr) and 2·8 × (CTBABr). Micellized tetradecylquinuclidinium bromide hexadecyl‐ N ‐methylmorpholinium are slightly better catalysts than CTABr, as is 1,3‐bis( ‐cetyl‐ , ‐dimethylamino)propane dibromide, but p...

Chloroperoxidase (CPO) is one of the most versatile heme peroxidase enzymes for synthetic applications. Despite potential use CPO, commercial processes have not been developed because low water solubility many organic substrates interest and limited stability due to inactivation by H(2)O(2). CPO catalytic properties studied in aqueous solutions presence short-chain poly(ethylene glycol)s (PEGs), sulfoxidation thioanisole, as model substrate, has investigated. The addition PEGs allows a...
Decarboxylation of the 6-nitrobenzisoxazole-3-carboxylate ion is speeded more by small assemblies didodecyl(dimethyl)ammonium chloride (DDDACl) than fully formed or normal cationic micelles. The first-order rate constants, k′M, reaction micelle-bound substrate increase with decreasing surface charge density micelles a change from hydrophilic to less counter-ions, e.g., in going CTAOH CTAOTos (CTA = C16H33NMe3 and Tos toluene-p-suIphonate), zwitterionic These changes are ascribed transfer...
The removal of biological colonization on building materials cultural heritage is a difficult challenge, as the treatment must completely eliminate patina without altering treated substrate and possibly delaying new colonization. With aim searching for systems to minimize biocide impact substrate, environment operators, different alginate–oxidizing hydrogels were previously tested optimized in laboratory here selected application situ. churches “San Pietro Barisano” “Madonna dei Derelitti”,...
