Studies of the Thermal and Mechanical Properties of Poly(urethane-siloxane)s Cross-Linked by Hyperbranched Polyesters
(American Chemical Society (ACS), 2012)
Polyurethane networks based on Boltorn hyperbranched polyesters (HBPs) of different pseudogenerations as cross-linkers, alpha,omega-dihydroxy(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO) and ...
Carbenic vs. ionic mechanistic pathway in reaction of cyclohexanone with bromoform
(Springer, New York, 2012)
The extensive computation study was done to elucidate the mechanism of formation dibromoepoxide from cyclohexanone and bromoform. In this reaction, the formation of dihaloepoxide 2 is postulated as a key step that determines ...
Investigation of the chemical composition-antibacterial activity relationship of essential oils by chemometric methods
(Springer Heidelberg, Heidelberg, 2012)
The antibacterial effects of Thymus vulgaris (Lamiaceae), Lavandula angustifolia (Lamiaceae), and Calamintha nepeta (Lamiaceae) Savi subsp. nepeta var. subisodonda (Borb.) Hayek essential oils on five different bacteria ...
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, ...
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 ...
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. ...
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 ...

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 ...
Non-canonical interactions of porphyrins in porphyrin-containing proteins
(Springer Wien, Wien, 2012)
In this study we have described the non-canonical interactions between the porphyrin ring and the protein part of porphyrin-containing proteins to better understand their stabilizing role. The analysis reported in this ...
