Fine-tuning the feature size of nanoporous silver
(Royal Soc Chemistry, Cambridge, 2012)
We show that the characteristic ligament size of nanoporous Ag synthesized by chemical dissolution of Al from Ag-Al alloys can be tuned from the current submicrometer size (similar to 100-500 nm) down to a much smaller ...
Visualisation of the interaction between Acidithiobacillus ferrooxidans and oil shale by atomic force microscopy
(Technical Faculty, Bor-Serbia, Bor, 2012)
This study visually documents the mechanical contact and interaction between the bacterial cells of two biogeocenotically different strains of Acidithiobacillus ferrooxidans (At. ferrooxidans) and oil shale containing ...
Core-shell structured tungsten-tungsten carbide as a Pt catalyst support and its activity for methanol electrooxidation
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Tungsten carbide was synthesized by calcination of carbon cryogel containing tungsten in a form of metatungstate. Characterization by X-ray diffraction and transmission electron microscopy indicated core-shell structure ...
Immobilization of biocatalysts for enzymatic polymerizations: Possibilities, advantages, applications
(Elsevier Sci Ltd, Oxford, 2012)
Biotechnology also holds tremendous opportunities for realizing functional polymeric materials. Biocatalytic pathways to polymeric materials are an emerging research area with not only enormous scientific and technological ...
Remote electron plasmon polaron in graphene
(Amer Physical Soc, College Pk, 2012)
The Coulomb interaction and the correlation of a remote electron with a single layer of graphene is investigated in the presence of a magnetic field applied perpendicular to the graphene layer. The remote electron polarizes ...
Processing and properties of silver-metal oxide electrical contact materials
(Association of Metallurgical Engineers of Serbia, 2012)
The presented study gives a brief overview of the experimental results of investigations of different production technologies of silver-metal oxide electrical contact materials in relation: processing method - properties. ...
Crystallographic and ab Initio Study of Pyridine Stacking Interactions. Local Nature of Hydrogen Bond Effect in Stacking Interactions
(American Chemical Society (ACS), 2012)
Stacking interactions between pyridine molecules and the influence of simultaneous hydrogen bonds were studied by analyzing data in the Cambridge Structural Database (CSD) and by ab initio calculations. The results show ...
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 ...
Synthesis of Allyl Acetates via Palladium-Catalysed Functionalisation of Allenes and 1,3-Dienes
(Stuttgart : Georg Thieme Verlag Kg, 2012)
pi-Allylpalladium intermediates are known to participate efficiently in transformations involving nucleophilic species. Exploring these processes, we have developed a method for the preparation of allyl acetates via ...
Microwave-assisted polyol synthesis of carbon-supported platinum-based bimetallic catalysts for ethanol oxidation
(Springer, New York, 2012)
High surface area carbon-supported Pt, PtRh, and PtSn catalysts were synthesized by microwave-assisted polyol procedure and tested for ethanol oxidation in perchloric acid. The catalysts were characterized by thermogravimetric ...
