Adsorption of some heavy metal ions by used different immobilized substances on silica gel
Abstract 8-Hydroxyquinoline, HQ, or poly(8-hydroxyquinoline), PHQ, was immobilized on the activated silica gel for extractive concentration of metal ions. FTIR was used to prove the result caused by the immobilization of PHQ on the surface of...

Graphene for separation and preconcentration of trace amounts of cobalt in water samples prior to flame atomic absorption spectrometry
Abstract A new sensitive and simple method was developed for the preconcentration of trace amounts of cobalt (Co) using 1-(2-pyridylazo)-2-naphthol (PAN) as chelating reagent prior to its determination by flame atomic absorption spectrometry. The...

Methylene blue sensitized oxidation of ethylene thiourea in cationic micellar medium
Abstract Ethylene thiourea (ETU) is relatively stable to hydrolysis but can be rapidly photolysed in the presence of photosensitizers. An aqueous solution of 8.0×10−4 M ETU and 5.0×10−5 M methylene blue (MB) ...

Oxidation of aniline and some para-substituted anilines by benzimidazolium fluorochromate in aqueous acetic acid medium – A kinetic and mechanistic study
Abstract The oxidation kinetics of some para-substituted anilines by benzimidazolium fluorochromate (BIFC) have been studied in aqueous acetic acid media in the presence of perchloric acid. The reaction is first order with respect to both aniline...

Reliable set-up for in-loop 11C-carboxylations using Grignard reactions for the preparation of [carbonyl-11C]WAY-100635 and [11C]-(+)-PHNO
Abstract Aim of this work was the implementation of a generalized in-loop synthesis for 11C-carboxylations and subsequent 11C-acylations on the TRACERlab FxC Pro platform. The set-up was tested using [carbonyl- 11C]WAY-100635...

Pleiotropic effects of statins: A boulevard to cardioprotection
Abstract 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, referred to as “statins” have been extensively reported to possess lipid lowering effects by inhibiting the synthesis of cholesterol by liver and thereby increasing...

Influence of Fatty Acid Structure on Fuel Properties of Algae Derived Biodiesel
Abstract Physical and chemical properties of biofuel are influenced by structural features of fatty acid such as chain length, degree of unsaturation and branching of the chain. A simple and reliable calculation method to estimate fuel property is...

Greatly enhanced detection of a volatile ligand at femtomolar levels using bioluminescence resonance energy transfer (BRET)
Abstract Our goal is to develop a general transduction system for G-protein coupled receptors (GPCRs). GPCRs are present in most eukaryote cells and transduce diverse extracellular signals. GPCRs comprise not only the largest class of integral...
