Tailor-made gold nanostar colorimetric detection determined by morphology change and used as an indirect approach by using hydrogen peroxide to determine glucose concentration

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

Selective oxidation of sulfides to sulfoxides by a vanadium-based catalyst using 30% hydrogen peroxide

The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...

Gold nanodot-based luminescent sensor for the detection of hydrogen peroxide and glucose.

We unveil a new luminescent assay using 11-mercaptoundecanoic acid-bound Au nanodots (11-MUA-Au NDs) for the highly selective and sensitive detection of hydrogen peroxide and glucose, based on luminescence quenching.
