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 ...
Arsenic in drinking water and acute coronary syndrome in Zrenjanin municipality, Serbia
(Academic Press Inc Elsevier Science, San Diego, 2012)
Background: Arsenic is constantly present in drinking water supply systems of Zrenjanin municipality across decades. It presents a great public health problem in Serbia, but its relationship with acute coronary syndrome ...
Catalysis of oxygen reduction on Au modified by Pd nanoislands in perchloric acid solution
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Oxygen reduction reaction (ORR) was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands in 0.1 M HClO4 solution using rotating disc electrode technique. Paladium was spontaneously deposited ...
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. ...
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 ...
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 ...
Deposition of silver ions onto DBD and DCSBD plasma treated nonwoven polypropylene
(Elsevier, 2012)
The aim of this work is plasma activation of nonwoven polypropylene (PP) using two different ambient air plasma sources: volume dielectric barrier discharge (DBD) and diffuse coplanar surface barrier discharge (DCSBD) and ...
Size-segregated mass concentration and water soluble inorganic ions in an urban aerosol of the Central Balkans (Belgrade)
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The distribution of nano/micron inorganic main ions in the size-segregated urban aerosol of Belgrade center was studied during the summer-autumn of 2008. The particle size distribution in the size ranges D(p) LT = 0.49 ...
Printed Planar 8 x 8 Array Antenna With Circular Polarization for Millimeter-Wave Application
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2012)
A new type of printed millimeter planar antenna with circular polarization for 60-GHz range is proposed. Radiation elements with two open tape rings are arranged in a two-dimensional 8 x 8 antenna array. Feeding is synphase ...
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 ...
