Synthesis and biological activity of some new aminoacylcarbazole derivatives. Part I
(
Wiley-Blackwell
, 1982 , Article)
The syntheses of different 9-(N-phthalyl- or N-tosyl- or free aminoacyl)carbazoles and the corresponding derivatives of 3,6-dinitrocarbazoles and some derivatives of 3,6-diamino-9-(N-phthalylaminoacyl)carbazoles (II-XXXII) ...
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 ...
Reduction kinetics of ceria surface by hydrogen
(
Wiley Periodicals, Inc.
, 2004 , Article)
Powdered cerium dioxide (ceria, CeO2) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm?3, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity ...
Kinetics and mechanism of H2O2 decomposition by Cu(II)-, Co(II)-, and Fe(III)-Amine complexes on the surface of Silica-Alumina (25% Al2O3)
(
John Wiley & Sons, Inc.
, 1994 , Article)
The kinetics of the H2O2 decomposition by Cu(II)-, Co(II)-, and Fe(III)-amine complexes supported on the surface of silica-alumina (25% Al2O3) catalyst have been investigated. The decomposition process proceeded with ...
Polarization Resistance Study on Copper Corrosion in Aqueous Potassium Hydrogen Phthalate Solution
(
WILEY-VCH Verlag
, 1987 , Article)
The effect of temperature on corrosion of copper in 0.1 M aqueous solution of potassium hydrogen phthalate (KHPh) has been investigated using polarization resistance technique. it was found that that the corrosion rate in ...
Evidence for some prostaglandins in Allium sativum extracts
(
John Wiley & Sons, Ltd.
, 1988 , Article)
Homogenized garlic (Allium sativum Linn.) was extracted successively with organic solvents and the prostaglandin-rich fraction separated. Fractionation of the extract with column chromatography was performed. TLC of the ...
Theoretical study of laser light generation and color image formation: FA1:Cs+ and FA2:Li+ centers at the low coordination (100) and (110) surfaces of AgCl and AgBr
(
Wiley Periodicals, Inc.
, 2005 , Article)
The FA1:Cs+ and FA2:Li+ color centers at the low coordination (100) and (110) surfaces of AgCl and AgBr play important roles in laser light generation and color image formation. Double-well potentials at these surfaces are ...
Functional Overexpression and Purification of a Codon Optimized Synthetic Glucarpidase (Carboxypeptidase G2) in Escherichia coli
(
Springer US
, 2009 , Article)
Glucarpidase (former name: carboxypeptidase G2, or CPG2) is a bacterial enzyme that is widely used in detoxification of the cytotoxic drug, methotrexate, and in Antibody Directed Enzyme Prodrug Therapy for cancer treatment. ...
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 ...
Geology and petrology of the Hormuz dolomite, Infra-Cambrian: Implications for the formation of the salt-cored Halul and Shraouh islands, Offshore, State of Qatar
(
Elsevier Ltd
, 2008 , Article)
Geological investigations of the Halul and the Shraouh islands, offshore Qatar, indicate that most of their calcareous rocks, which display abundant stromatolitic bedding, belong to the Infra-Cambrian Hormuz Series. ...
