Platinum(II/IV) complexes containing ethylenediamine-N,N '-di-2/3-propionate ester ligands induced caspase-dependent apoptosis in cisplatin-resistant colon cancer cells
(Royal Soc Chemistry, Cambridge, 2012)
Several new R(2)eddp (R = i-Pr, i-Bu; eddp = ethylenediamine-N,N'-di-3-propionate) esters and corresponding platinum(II) and platinum(IV) complexes of the general formula [PtCln(R(2)edda-type)] (n = 2, 4) were synthesized ...
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, ...
Lossy gradient index transmission optics with arbitrary periodic permittivity and permeability and constant impedance throughout the structure
(IOP Publishing, 2012)
A remarkably simple exact analytical solution is obtained for the electromagnetic field distribution across infinite metamaterial-containing composites with any arbitrary periodic variation of complex effective permittivity ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Integer quantum Hall effect in gapped single-layer graphene
(Amer Physical Soc, College Pk, 2012)
Analytical expressions for the Hall conductivity sigma(yx) and the longitudinal resistivity rho(xx) are derived in gapped, single-layer graphene using linear response theory. The gap 2 Delta, described by a mass term, is ...
Al,Fe-pillared clays in catalytic decolorization of aqueous tartrazine solutions
(Elsevier, 2012)
In this work Al,Fe-pillared clays (PILCs) were applied as heterogeneous catalysts in catalytic wet peroxide oxidation of tartrazine azo-dye in water. A series of We PILCs with different Fe3+ content were synthesized. The ...
Characterization and behavior of anesthetic bioactive textile complex in vitro condition
(Wiley-Blackwell, Malden, 2012)
In this study, a bioactive complex containing nonwoven textile material (polypropilene (PP)/viscose), chitosan hydrogel, and lidocaine hydrochloride, was designed. The purpose of such biomedical textile was in the treatment ...
Silver/polystyrene nanocomposites: Optical and thermal properties
(Wiley-Blackwell, Hoboken, 2012)
Nanocomposites consisted of different quantities of silver (Ag) nanoparticles incorporated in a polystyrene (PS) matrix have been prepared by solution mixing method. Transmission electron microscopy was applied to determine ...
Correlate between morphology of powder particles obtained by the different regimes of electrolysis and the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2012)
Morphologies of copper powder particles obtained by both potentiostatic and pulsating overpotential (PO) regimes of electrolysis were investigated by the technique of scanning electron microscopy (SEM). Particles of dendritic ...
Formic acid oxidation on Pt-Au nanoparticles: Relation between the catalyst activity and the poisoning rate
(Elsevier, 2012)
Pt-Au nanoparticles supported on high area carbon were prepared by simultaneous reduction of Au and Pt precursors and by reduction of Pt precursor on already prepared Au nanoparticles. The first method produced a solid ...
