Synchrotron X-ray diffraction measurements have been conducted on aqueous mixtures of propan-2-ol (a.k.a. isopropanol, or 2-propanol), for alcohol contents between 10 and 90 mol%, from room temperature down to 230 K. Molecular dynamics simulations, by using an all-atom parametrization the molecule well-known TIP4P/2005 water model, were able provide semi-quantitative descriptions measured total...

The enantiomeric separation of antifungal compounds is an arduous task in pharmaceutical and biomedical fields due to the different properties that each diastereoisomer presents. enantioseparation a group fungicides (sulconazole, bifonazole, triadimefon triadimenol) using supercritical fluid chromatography was achieved this work. For goal, four chiral columns based on polysaccharide derivatives...

Polymethylmethacrylate (PMMA) is a material of choice for many biomedical coating applications. However, such applications are limited due to the toxicity traditional solvents used solution processing PMMA coatings and composites. This problem addressed using an isopropanol-water co-solvent, which allows dissolution high molecular mass fabrication by dip-coating method from concentrated solutio...

The electrochemical behavior of nifedipine (I), nitrendipine(II) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (PPC) as supporting electrolyte. It has been shown that I and II undergo in a 4e, 4H+ irreversible reduction reaction, while the reduc...

In this study, Kraft lignin was depolymerised by hydrothermal liquefaction in near-critical water (290–335 °C, 250 bar) using Na2CO3 as an alkaline catalyst. Isopropanol used a co-solvent with the objective of investigating its capping effect and capability reducing char formation. The resulting product, which mixture aqueous liquid, containing water-soluble organic compounds, char, had lower s...

The purpose of this study was to investigate the influence of electron beam (EB) irradiation on the structure and physical properties of Nafion 117 membranes (in both acid and sodium forms) when they are irradiated in water and isopropanol as solvents. The mechanical properties of Nafion membranes in acid form irradiated in water were found to rapidly deteriorate as the irradiation dose was inc...

Love-wave gas sensors based on surface functionalized iron oxide nanoparticles has been developed in this research. Amino-terminated iron oxide nanoparticles were deposited, by a spin coating technique, onto the surface of Love-wave sensors, as a very reproducible gas-sensing layer. The gases tested were organic solvents, such as butanol, isopropanol, toluene and xylene, for a wide and low conc...

background cancer is one of the leading causes of human death. the discovery of new generations of low-cost anticancer drugs with high efficacy and low toxicity is necessary, and is only possible by screening medicinal plants with prior knowledge. objectives in this study, the bioactivities of three medicinal plants from india, including alstonia scholaris, alstonia venenata, and moringa oleife...
