a novel potentiometric ion-selective pvc membrane sensor for analysis of atorvastatin (at) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (at-(tpb)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (top) as plasticizer solvent was prepared. the electrode shows a good nernestian response over the concentration range of 0.09–5586 µg ...

an extensive study of higher alcohols synthesis (has) from syngas using alkalized mos2 catalysts supported on carbon nanotubes (cnts) is reported. up to 30wt.% of mo and 8wt.% k are added to the cnts by impregnation method. the catalysts were characterized by different methods and the performance of the catalysts was assessed in a micro-reactor. tem images showed that most of the metal particle...

we explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized tio2 matrix. these electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to tio2 nanotubes, respectively. titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (eg) fluoride-c...

sulphuric acid adsorbed on silica gel is a practical and useful catalyst for acetylation of varius alcohols, phenols and amines.

background: opioid abuse is common in iran. in recent years, methadone maintenance therapy (mmt) has gained popularity in this country. this study aimed at evaluation concurrent abuse of alcohol in patients under mmt. methods: a predesigned questionnaire was developed and completed after obtaining verbal consent among 49 subjects under mmt in kian rehabilitation centre during january 2014. resu...

Toxic alcohols that clinicians commonly encounter are ethylene glycol, methanol, and isopropanol. Adults ingest these either for suicidal intent or to achieve inebriation, since these substances are readily available and cheaper than alcohol. Nevertheless, assorted alcohols are used very often in many applications and any alcohol can be toxic if ingested in large enough quantities. Toxic alcoho...

 The catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. In the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products ...
