Properties of a three-dimensionally ordered macro-mesoporous carbon-doped TiO2 composite catalyst
(
World Scientific Publishing
, 2013 , Article)
This study aimed to develop an effective, environmentally benign composite catalyst composed of carbon materials and titanium dioxide (TiO2). Carbon-doped titanium dioxide (C-TiO2) was prepared by coating TiO2 onto ...
Studies on chemistry, spectroscopy and antioxidant activities of chromium(III)-hydrazide complexes
(
Bentham Science Publishers B.V.
, 2015 , Article)
Acid hydrazides are vital chemical entities due to their biological activities. Upon complexation with certain metal ions, their biological activities are known to be positively enhanced. The present work describes the ...
Inhibiting corrosion of n-GaAs by cetylpyridinium chloride for stabilised photoelectochemical cell
(
Maney Publishing
, 2010 , Article)
The cationic surfactant cetylpyridinium chloride (CPC) provides photocorrosion inhibition to the GaAs surface when CPC is chemisorbed on the GaAs surface from aqueous acidic electrolytes at concentrations of CPC lower than ...
A novel platinum complex of the histone deacetylase inhibitor belinostat: Rational design, development and in vitro cytotoxicity
(
Elsevier Inc.
, 2013 , Article)
The successful design and synthesis of a novel Pt complex of the histone deacteylase inhibitor belinostat are reported. Molecular modelling assisted in the identification of a suitable malonate derivative of belinostat(mal-p-Bel) ...
Spectral, thermal, and molecular modeling studies on the encapsulation of selected sulfonamide drugs in ?-cyclodextrin nano-cavity
(
Elsevier
, 2014 , Article)
In the present work the inclusion complexation of three sulfonamide (SA) drugs, namely sulfisoxazole (SSX), sulfamethizole (SMZ), and Sulfamethazine (STM) with β-cyclodextrin (β-CD) has been investigated using UV–Vis ...
Mishandling and exposure of farm workers in Qatar to organophosphate pesticides
(
Elsevier Inc.
, 2014 , Article)
We used a combination of subjective (questionnaire) and objective (urinary metabolites) measurements to evaluate factors that can predict the exposure of farm workers in Qatar to organophosphate pesticides and to assess ...
Self-assembled zirconia nanotube arrays: Fabrication mechanism, energy consideration and optical activity
(
Royal Society of Chemistry
, 2014 , Article)
We present a comprehensive roadmap for the precise control of the dimensions and optical properties of anodically fabricated zirconia nanotubes. The effects of anodization time, applied voltage, solvent composition, as ...
Biophysical studies of the effect of high power ultrasound on the DNA solution
(
Elsevier B.V.
, 2014 , Article)
Stability and molecular size of the DNA double helical structure were studied on an aqueous solution of DNA after exposure to high power doses of continuous wave ultrasound at frequency of 20kHz. Thermal transition ...
Evaluation of pesticide residues of organochlorine in vegetables and fruits in Qatar: statistical analysis
(
Springer Verlag
, 2016 , Article)
The study aimed to examine the residues of organochlorines pesticides (OCPs) in vegetables and fruits in Qatar. A total of 127 samples was studied. Ninety percent of the imported samples recorded residues above the maximum ...
Kinetic investigations into the synthesis of disulphides via tetrathiomolybdate as a sulphur-transfer reagent
(
Kluwer Academic Publishers
, 2014 , Article)
Kinetic and mechanistic aspects of the conversion of halides to disulphides using benzyl triethyl ammonium tetrathiomolybdate as sulphur-transfer reagent were investigated. The reaction follows a 1:1 stoichiometry with ...
