A very simple, ultra-sensitive and highly selective non-extractive spectrophotometric method for the determination of trace amount of molybdenum(VI) using 5,7-dibromo-8-hydroxyquinoline (DBHQ) has been developed. 5,7-Dibromo-8-hydroxyquinoline reacts in a slightly acidic solution (0.05 - 1.0 M H2SO4) with molybdenum(VI) to give a deep greenish-yellow chelate which has an absorption maximum at 4...

We study the selective catalytic oxidation of ethanol with air as a sustainable alternative route to acetaldehyde. The reaction is catalysed by molybdenum oxide supported on titania, in a flow reactor under ambient pressure. High selectivity to acetaldehyde (70%-89%, depending on the Mo loading) is obtained at 150 °C. Subsequently, we investigate the structure/performance relationship for vario...

A dithiocarbamate-based methodology is employed to prepare linked heteromultimetallic complexes and then further exploited in the surface functionalisation of gold nanoparticles.

A rare class of mixed-metal [2]catenane has been assembled via magic ring synthesis of dinuclear copper(II) and gold(III) dithiocarbamate macrocycles.

In this study, molybdenum-copper/alumina nano composite was synthesized with mechano-chemical method using high energy planetary ball milling. The molybdenum oxide, copper oxide and aluminum powder were used as starting materials and reaction appeared to occur through a rapid combustion reaction process. The evaluation of powder particles after different milling times was studied by X-ray diffr...

   Nickel-molybdenum oxidebimetallic nanoparticles were synthesized in ethylene glycol using the microwave irradiation technique. According to the results, successive reduction of nickel and molybdenum ions, followed by thermal treatment of obtained nanoparticles led to formation of core-shell structured nickel-molybdenum oxide nanoparticles. According to the results, the thickness of the s...

With the exception of nitrogenase, molybdenum is present in a diverse, but coherent group of enzymes which contain a pterin molybdenum cofactor (Moco) as a prosthetic group [l]. This group of enzymes, known as the molybdenum oxotransferases and hydroxylases, carry out a two-electron oxidation-reduction reaction which is linked to oxygen atom transfer to or from a substrate. This is illustrated ...

Dithiocarbamate chemistry is used as a crosslinking tool to fabricate FePt colloidal microcapsules which provide a versatile scaffold for "host-guest" recognition at the liquid-liquid interface.

Objective: The coordination and electrochemistry-related effects uses of piperidine dithiocarbamate (pipdtc) piperazine (pzdtc) are the main topics this article. Method: An environment friendly electroless bath was created using a very small amount biodegradable methanesulphonic bronsted acid, Glyoxylic acid as reducing agent, Xylitol non-toxic natural polyhydroxylic complexing agent potassium ...

Studies on the respiratory nitrate reductase (EC 1.7.99.4) from Escherichia coli K12 by electron-paramagnetic-resonance spectroscopy indicate that its molybdenum centre is comparable with that in other molybdenum-containing enzymes. Two Mo(V) signals may be observed; one shows interaction of Mo(V) with a proton exchangeable with the solvent and has: A (1H) 0.9-1.2mT; g1 = 1.999; g2=1.985; g3 = ...
