Comparison of properties of silver-metal oxide electrical contact materials
(Technical Faculty, Bor, 2012)
Changes in physical properties such as density, porosity, hardness and electrical conductivity of the Ag-SnO2 and Ag-SnO2In2O3 electrical contact materials induced by introduction of metal oxide nanoparticles were investigated. ...
The synthesis of 2,5-bis(4-amidinophenyl)thiophene derivatives providing submicromolar-range inhibition of the botulinum neurotoxin serotype A metalloprotease
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2012)
Botulinum neurotoxins (BoNTs), composed of a family of seven serotypes (categorized A-G), are the deadliest of known biological toxins. The activity of the metalloprotease, light chain (LC) component of the toxins is ...
Far infrared study of local impurity modes of Boron-doped PbTe
(Springer, New York, 2012)
PbTe single crystals, doped with B, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and room temperature. The experimental spectra were numerically analyzed, ...
Streptomyces sp JS520 produces exceptionally high quantities of undecylprodigiosin with antibacterial, antioxidative, and UV-protective properties
(Springer, New York, 2012)
A Gram-positive, red-pigment-producing bacterial strain, designated JS520 was isolated from the pristine sediment from the cave on mountain Miroc in Serbia. Strain was confirmed to belong to Streptomyces genus based on ...

Microporous conducting carbonized polyaniline nanorods: Synthesis, characterization and electrocatalytic properties
(Elsevier, 2012)
Microporous conducting nitrogen-containing nanostructured carbon with excellent catalytic activity for the electrochemical synthesis of hydrogen peroxide was synthesized by the carbonization of self-assembled polyaniline ...
Maskless convex corner compensation technique on a (100) silicon substrate in a 25 wt% TMAH water solution
(Iop Publishing Ltd, Bristol, 2012)
A maskless convex corner compensation technique in a 25 wt% TMAH water solution at the temperature of 80 degrees C is presented and analyzed. The maskless convex corner compensation technique is defined as a combination ...
A novel C,D-spirolactone analogue of paclitaxel: autophagy instead of apoptosis as a previously unknown mechanism of cytotoxic action for taxoids
(Royal Soc Chemistry, Cambridge, 2012)
The design, synthesis and biological evaluation of a novel C, D-spirolactone analogue of paclitaxel is described. This is the first paclitaxel analogue without an oxetane D-ring that shows a significant cytotoxic effect ...
Crystal structure and conformational analysis of s-cis-(acetylacetonato)(ethylenediamine-N,N '-diacetato)-chromium(III)
(Springer, New York, 2012)
The crystal structure of [Cr(edda)(acac)] (edda = ethylediamine-N,N'-diacetate; acac = acetylacetonato) has been determined by a single crystal X-ray diffraction study at 150 K. The chromium ion is in a distorted octahedral ...
Toward enhanced hydrogen production in a catalytic naphtha reforming process
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries. The catalytic naphtha reformer (CNR) process is ...
