Ab Initio Quantum Study of Nonadiabatic S-1-S-2 Photodynamics of s-trans-Butadiene
(American Chemical Society (ACS), 2013)
The nonadiabatic photodynamics of s-trans-butadiene in its lowest singlet excited states is studied theoretically, using a fully quantal approach. The coupled 1B(u) and 2A(g) states are considered in the calculation, ...
Segregation in water fluidized beds of sand particles
(Elsevier Science Sa, Lausanne, 2013)
Fluidization experiments were conducted on four fractions of filtration (quartz) sand using columns of 144 and 64 mm i.d. The size distribution of the fractions obtained by sieving followed an approximately modified normal ...
Antioxidant Evaluation of Heterocyclic Compounds by Cytokinesis-Block Micronucleus Assay
(Bentham Science Publ Ltd, Sharjah, 2013)
This article summarizes the results of using cytokinesis-block micronucleus (CBMN) assay to evaluate the antioxidant potential of heterocyclic compounds. Most studies were carried out with naturally occurring heterocyclic ...
Integer quantum Hall effect in single-layer graphene with tilted magnetic field
(Amer Inst Physics, Melville, 2013)
Analytical expression for the Hall conductivity sigma(yx) in graphene is derived in more general case, in which magnetic field is not perpendicular to the plane of the sample. The derivations were carried out using ...
Synthesis, cytotoxic activity and DNA-interaction studies of novel anthraquinone-thiosemicarbazones with tautomerizable methylene group
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2013)
A series of novel anthraquinone thiosemicarbazone derivatives in a tautomerizable keto-imine form was synthesized and tested for their in vitro cytotoxic activity against human cancer cells (HeLa, MDA-MB-361, MDA-MB-453, ...
Renewable silver-amalgam film electrode for voltammetric monitoring of solar photodegradation of imidacloprid in the presence of Fe/TiO2 and TiO2 catalysts
(Elsevier, 2013)
A rapid and sensitive voltammetric method has been developed for the characterization and determination of the imidacloprid insecticide by means of square-wave voltammetry (SWV) with a silver-amalgam film electrode (Hg(Ag)FE) ...
Degradation of Thiacloprid by ZnO in a Laminar Falling Film Slurry Photocatalytic Reactor
(American Chemical Society (ACS), 2013)
The possibility of the use of the laminar falling film slurry type photoreactor was examined in conjunction with ZnO as a photocatalyst for the removal of thiacloprid (TCL) from Calypso 480-SC commercial formulation by UV ...
Antimicrobial viscose fabric prepared by treatment in DBD and subsequent deposition of silver and copper ions-Investigation of plasma aging effect
(Elsevier, 2013)
In this work, the effect of dielectric barrier discharge (DBD) in ambient air on preparation of antimicrobial viscose fabric was studied. DBD plasma treatment was applied under constant discharge power and different exposure ...
Chemistry of the sternal gland secretion of the Mediterranean centipede Himantarium gabrielis (Linnaeus, 1767) (Chilopoda: Geophilomorpha: Himantariidae)
(Springer, New York, 2013)
The geophilomorph centipede, Himantarium gabrielis, when disturbed, discharges a viscous and proteinaceous secretion from the sternal glands. This exudate was found by gas chromatography-mass spectrometry, liquid ...
Modification of high density polyethylene by gold implantation using different ion energies
(Elsevier Science Sa, Lausanne, 2013)
High density polyethylene (HDPE) samples were modified by Au+ ion implantation at a dose of 5 x 10(15) ions cm(-2), using energies of 50, 100, 150 and 200 keV. The existence of implanted gold in the near-surface region of ...
