The effect of PtRuIr nanoparticle crystallinity in electrocatalytic methanol oxidation
(MDPI, 2013)
Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as ...
Amorphous Pt@dCu/CNT catalyst for methanol elextrooxidation
(South African Chemical Institute (SACI), 2013)
A multi-walled carbon nanotube-supported, Pt decorated nano-sized amorphous PdCu alloy cores (denoted as Pt@PdCu/CNT)
catalyst with lower Pt loading is synthesized via a galvanic displacement reaction. The structure is ...
Cytotoxic, cytostatic and HIV-1 PR inhibitory activities of the soft coral litophyton arboreum
(MDPI, 2013)
Bioassay-guided fractionation using different chromatographic and spectroscopic techniques in the analysis of the Red Sea soft coral Litophyton arboreum led to the isolation of nine compounds; sarcophytol M (1), alismol ...
A new vanadium (III) complex of 2,6-Bis(3,5-diphenylpyrazol- 1-ylmethyl)pyridine as a catalyst for ethylene polymerization
(MDPI, 2013)
The tridentate ligand 2,6-bis(3,5-diphenylpyrazol-1-ylmethyl)pyridine,
abbreviated as 2,6-[(3,5-ph2pz-CH2)2-py], a new pyridine-pyrazole derivative, was
prepared from 2,6-bis(bromomethyl)pyridine and 3,5-diphenylpyrazole. ...
Marrubiin
(MDPI, 2013)
The ethno-medicinal approach to drug discovery represents one of the most
important sources of new and safe therapeutic agents to the challenges confronting modern
medicine and daily life. Many of the traditionally ...
Effect of ni core structure on the electrocatalytic activity of pt-ni/c in methanol oxidation.
(MDPI, 2013)
Methanol oxidation catalysts comprising an outer Pt-shell with an inner Ni-core supported on carbon, (Pt-Ni/C), were prepared with either crystalline or amorphous Ni core structures. Structural comparisons of the two forms ...
Synthesis of zeolites Na-P1 from South African coal fly ash: effect of impeller design and agitation
(MDPI, 2013)
South African fly ash has been shown to be a useful feedstock for the synthesis
of some zeolites. The present study focuses on the effect of impeller design and agitation
rates on the synthesis of zeolite Na-P1 which are ...
Salicylaldiminato chromium complex supported on chemically modified silica as highly active catalysts for the oxidation of cyclohexene
(Elsevier, 2013)
Immobilization of chromium complexes on modified silica support was achieved via two different synthetic routes using 3-aminopropyl triethoxysilane (APTS) as a linking group. The FTIR spectra, elemental and solid-state NMR ...
Synthesis of an ordered mesoporous carbon with graphitic characteristics and its application for dye adsorption
(Springer, 2013)
An ordered mesoporous carbon (OMC) was prepared by a chemical vapor deposition technique using liquid petroleum gas (LPG) as the carbon source. During synthesis, LPG was effectively adsorbed in the ordered mesopores of ...
Imino-phospine palladium (II) and platinum (II) complexes: Synthesis, molecular structures and evaluation as antitumor agents
(Elsevier, 2013)
The imino-phosphine ligands L1 and L2 were prepared via condensation reaction of 2-(diphenylphosphino)
benzaldehyde with substituted anilines and obtained in very good yields. An equimolar reaction of L1 and L2
with ...
