“…Diferuloylmethane (Curcumin), important bioactive component, is a natural phenolic compound derived from the spice turmeric (Curcuma longa). Many studies have shown that this compound can be used in a large variety of applications such as pharmacology for its anticancer, antimutagenic, antibacterial, anti‐inflammatory, antifungal, anti‐allergy, and antioxidant features . Lipophilic properties of curcumin lead to its low aqueous solubility and poor bioavailability, resulting in high rate of digestion and fast removal from the body .…”

Considering the utility of cyclodextrin nanosponges for the encapsulation of drugs, in this study, the effect of drug loading method on the release property of the resulting complex is studied. To this purpose, curcumin as a model substrate was loaded into the cyclodextrin nanosponge via three different methods, including freeze drying, impregnation and physical mixing.All three complexes were characterized and the release profile of curcumin from them was investigated.[a] M.

“…Previous reports also suggested that the increasing cathode dissolution at high temperature could be attributed to the decreased viscosity at higher temperature. 36,43 However, while the temperature is higher than 100 °C (e.g., 120 °C), the Co concentration is decreased, which might be mainly due to the reason that the escape rate of the LCO compound from DESs is higher than the dissolving rate. Therefore, although the mass transfer is improved and viscosity is decreased at 120 °C, the Co concentration decreases.…”

Mild and green dissolution of lithium cobalt oxide (LCO) with high efficiency is challenging. Here, novel DESs based on poly(ethylene glycol) 200 and p-toluenesulfonic acid monohydrate are designed and found to dissolve LCO with nearly a 100% leaching efficiency at 100 °C within 24 h, which is much higher than the leaching efficiency by DESs in the reported references. The dissolution mechanism investigation shows that the interaction between DESs and LCO is a physical process. This work provides a new strategy for the mild and efficient dissolution of LCO by cheap and green solvents.

“…DESs were prepared according to the methods reported previously. [ 24b,28 ] In order to synthesize DES, a certain molar ratio (4: 1 or 2: 1) of HBD (PEG 200 or glycerol) and HBA (choline chloride) was mixed and then heated at 80°C under continuous stirring until a homogeneous and transparent liquid was formed. The obtained DESs were used in reactions without any purification.…”

An efficient and retrievable copper(I) catalyst was synthesized by immobilizing of copper iodide on 3‐thionicotinyl‐urea‐modified magnetic nanoparticles and characterized using a variety of analysis techniques. The catalytic activity of these nanoparticles was investigated in the one‐pot three‐component reaction of aryl halides, sodium azide, and terminal alkynes using choline chloride/PEG deep eutectic mixture as a green and recoverable solvent. The PEGylated deep eutectic solvent (DES), due to its favorable polarity and solubility, can make an effective association of polar and non‐polar reactants during the reaction, thereby accelerating the catalysis process. An array of 1‐aryl 1,2,3‐triazoles were obtained in good to excellent yields. The catalyst system can be readily recovered and reused at least five times with no appreciable loss of its activity.
