endo-Mode cyclizations of vinylogous N-acyliminium ions as a route to the synthesis of condensed thiazolidines
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
endo-Mode cyclizations of vinylogous N-acyliminium ions incorporating heteroatom-based nucleophiles have been examined as a route to the synthesis of condensed thiazolidines. The scope of these reactions and stereochemical ...
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 ...
Structure-Property Correlation Study of Novel Poly(urethane-ester-siloxane) Networks
(American Chemical Society (ACS), 2013)
Novel poly(urethane-ester-siloxane) networks, based on hydroxypropyl terminated poly(dimethylsiloxane) (PDMS), 4,4'-methylenediphenyl diisocyanate, and hyperbranched polyesters (HBPs) of the second and third pseudogenerations, ...
A new insight into the mechanism of lead electrodeposition: Ohmic-diffusion control of the electrodeposition process
(Elsevier, 2013)
A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology ...
An Approach to Nanobioparticles - Synthesis and Characterization of Fulleropeptides
(Wiley-V C H Verlag Gmbh, Weinheim, 2012)
Two sets of new peptides incorporating fulleropyrrolidine units Fp-GABAn-Glym-OtBu have been designed, synthesized and completely characterized. In the first series the chain contained only GABA (?-aminobutyric) residues, ...
Studies of the regioselective ring-opening closing mode of functionally different thiazolidine type enaminones: en route to the synthesis of trithiaazapentalene derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Trithiaazapentalene derivatives were prepared by the reaction of 2-alkylidene-4-oxothiazolidines with Lawesson's reagent. They are classified as two structurally different trithiaazapentalene compounds that have different ...
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, ...
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 ...
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 ...
