In this study, we present a new concept in chemically stabilized ionic liquid membranes: an ionic liquid organosilica (ILOS) membrane, which is an organosilica membrane with ionic liquid-like properties. A silylated ionic liquid was used as a precursor for synthesis. The permselectivity, permeation mechanism, and stability of the membrane in the H₂/toluene binary system were then compared with ...

Nanostructured solid composite electrolyte or nano-SCE, which is composed of an ionic liquid, nanoporous silica, and residuals immobilized precursor components, shows promising synergistic properties. The conductivity nano-SCE in the range 2–5 mS cm−1, exceeds bulk liquid at ambient temperature, while maintaining characteristics a such as having no leakage issues confined, lower flammability co...

diosmin and hesperidin are natural flavonoid glycosides found in various plant materials, mainly in citrus fruits in different concentrations. diosmin for pharmaceutical use is obtained mainly semi-synthetically from hesperidin. hesperidin often accompanies diosmin as a natural impurity in different pharmaceutical formulations; therefore, a simple, fast and precise method for the simultaneous a...
