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 ...
An LFER study of the protolytic equilibria of 4-aryl-2,4-dioxobutanoic acids in aqueous solutions / Linearne korelacije slobodne energije (LFER) protolitičkih ravnoteža 4-aril-2,4-dioksobutanskih kiselina u vodenim rastvorima
(Srpsko hemijsko društvo, Beograd, 2007)
The protolytic equilibria of 13 4-aryl-2,4-dioxobutanoic acids (ADKs) were spectrophotometrically studied in aqueous solutions in the pH range 1-9 at 25±1 °C and an ionic strength of 0.1 mol l-1 (NaCl), with the exception ...
Phase equilibria investigation and characterization of the Au-In-Sb system
(Metalurgija, 2007)
The Au-In-Sb system belongs to the group of potential candidates for lead-free solder materials. The results of phase equilibria investigation and characterization of the alloys in the Au-In-Sb section are presented in ...
Carbon monoxide oxidation on Au(111) surface decorated by spontaneously deposited Pt
(Elsevier, 2007)
Platinum is deposited spontaneously on Au(1 1 1) surface from 1 mM H2PtCl6 + 1 M HClO4 solution using multiple deposition procedure. X-ray photoelectron spectroscopy (XPS) analysis has shown that after immersion into the ...

Phase composition, structure and magnetic behaviour of low neodymium Nd-Fe-B permanent magnets
(Metalurgija, 2007)
Phase composition, structure and magnetic behaviour of two low neodymium hard magnetic materials differing in way of preparation, centrifugal atomization and melt spinning, were compared using Mössbauer spectroscopy, X-ray ...
Phase composition and magnetic properties of multiphase melt-spun Nd 4.3Fe76.2B19.5alloy
(Materials Science Forum, 2007)
Phase transformations and magnetic properties of multiphase Nd 4.5Fe76.2B19.5 alloy were investigated in the temperature range of heat treatment 600-700°C. The influence of different heat treatment regimes was observed by ...
Obtaining nano calcium phosphate/poly(dl-lactide-coglycolide) composite biomaterial by sonochemical deagglomeration
(Belgrade: Institute of Technical Sciences of SASA, 2007)
Nanoparticles have several advantages over the microparticles in interactions of thebiomaterial with the organism. The response of the organism depends on the interaction of thebiomaterial with the surrounding tissue and ...
Freshwater Cyanobacterial blooms and Cyanotoxin production in Serbia in the past 25 years
(University of Novi Sad, Department of Geography, Tourism and Hotel Management, 2007)
Since 1980 cyanobacterial blooms occurred in a large number of reservoirs lakes and water flows (rivers and channels) in Serbia. Among 83 water ecosystems examined, 58 were found in blooming condition almost every year ...
Steroid template associated peptides: design, synthesis and 2D NMR characterization of a novel protected 18-Phe,19-Gly-containing steroidal compound
(Oxford : Pergamon-Elsevier Science Ltd, 2007)
We report herein the synthesis of a novel modified steroid with two rigidly positioned amino acids in C- and N-protected forms (Gly-OtBu and N-Fmoc-l-Phe) at the angular positions (C-18 methylamino group and C-19 carboxylic ...
