Geochemical investigation and characterisation of Neogene sediments from Valjevo-Mionica Basin (Serbia)
(Springer, New York, 2009)
Sediments from the Valjevo-Mionica Basin of Neogene age were investigated in this study using different geochemical methods. The results of the inorganic part analyses suggest that during genesis of the sediments, the ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Elsevier, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
A comparative thermomagnetic study of melt-spun Nd-Fe-B alloys with different Nd content
(International Institute for the Science of Sintering, Beograd, 2009)
Changes in the phase composition and magnetic properties of three types of commercial Nd-Fe-B alloys with different Nd content - low (10-12 wt%), near stoichiometric (21-25 wt%) and rich (26-29 wt%) caused by thermomagnetic ...
Copper(II) complexes of N-heteroaromatic hydrazones: Synthesis, X-ray structure, magnetic behavior, and antibacterial activity
(Elsevier Science Sa, Lausanne, 2009)
Three novel copper(II) complexes as condensation derivatives of 2-pyridinecarboxaldehyde, 2-acetylpyridine or 2-quinolinecarboxaldehyde with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures ...
A novel lectin from the sponge Haliclona cratera: isolation, characterization and biological activity
(Elsevier Science Inc, New York, 2002)
A lectin from the Adriatic sponge Haliclona cratera was purified by ion-exchange and gel chromatography The molecular mass of the lectin is approximately 29 kDa. Purified lectin is rich in hydrophobic and basic amino acids ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Journal of Optoelectronics and Advanced Materials, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymer-magnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
Evaluation of Hypericum perforatum oil extracts for an antiinflammatory and gastroprotective activity in rats
(Phytotherapy Research, 2009)
Oil extracts of Hypericum perforatum L. (Oleum Hyperici) were prepared in three different ways according to the prescriptions from traditional medicine. Variability of constituents and biological activity were evaluated ...
Molecular mechanics study of nickel(II) octaethylporphyrin adsorbed on graphite(0001)
(MDPI, 2007)
The effects of adsorption on the graphite(0001) surface on the nonplanar distortions of nickel(II) octaethylporphyrin were studied by molecular mechanics (MM) approach. Using the Consistent Force Field (CFF) program with ...
Structural and phase composition modification of nanocrystalline Nd14Fe79B7 alloy during thermomagnetic measurements
(Technical Faculty, Bor, 2009)
Changes in the microstructure parameters, phase composition and magnetic properties of rapid quenched Nd-rich Nd14Fe79B7 alloy caused by thermomagnetic measurement (TM) were studied using XRD methods of phase analysis, ...
Synthesis and biological evaluation of some 17-picolyl and 17-picolinylidene androst-5-ene derivatives
(Elsevier, 2007)
Starting from dehydroepiandrosterone (1) 17-picolyl (2), 17-picolinylidene (7), 17-picolinylidene-16-one (10 and 11), and 17-picolyl-16-one (15) derivatives of androst-5-ene were synthesized in one, two, four and five steps ...
