Nanocomposite permanent magnetic materials Nd-Fe-B type: The influence of nanocomposite on magnetic properties
(Technical Faculty, Bor, 2005)
The influence on the magnetic properties of nanocristalline ribbons and powders has character of microstructure, between others – the grain size volume of hard and soft magnetic phases and their distribution. Magnetic ...
Modeling of coating optical fibers with polymer-magnetic powder composite coating
(International Institute for the Science of Sintering, Beograd, 2002)
A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological ...
Research on Chemical Composition and Biological Properties Including Antiquorum Sensing Activity of Angelica pancicii Vandas Aerial Parts and Roots
(American Chemical Society (ACS), 2017)
The essential oil, different extracts, and isolated compounds of Angelica pancicii Vandas (Apiaceae) were investigated for the first time. The GC-FID and GC-MS analyses revealed sesquiterpenoids as the main constituents ...
Isolation, characterization and in vitro cytotoxicity of new sesquiterpenoids from Achillea clavennae
(Georg Thieme Verlag, 2014)
Further phytochemical investigation into the aerial parts of Achillea clavennae has resulted in the 3 isolation of three new sesquiterpene lactones: two highly oxygenated germacranolides (1, 2) and 4 the iso-seco-guaianolide, ...
Complexes of Zn(II)–Triazoles with CO2 and H2O: Structures, Energetics, and Applications
(American Chemical Society (ACS), 2019)
Using a first-principle methodology, we investigate the stable structures of the nonreactive and reactive clusters formed between Zn2+–triazoles ([Zn2+-Tz]) clusters and CO2 and/or H2O. In sum, we characterized two modes ...
Antioxidant Activity of Wines Determined by a Polarographic Assay Based on Hydrogen Peroxide Scavenge
(American Chemical Society (ACS), 2010)
Antioxidant (AO) activity of various red and white wines of different origin as well as some individual phenolic compounds present in wine has been assessed using a polarographic assay. Direct current polarography has been ...
Secondary metabolites of three endemic Centaurea L. species
(Serbian Chemical Soc, Belgrade, 2014)
The aerial parts of three endemic Centaurea L. species, namely C. tomorosii Micevski, C. soskae Hayek and C. galicicae Micevski, afforded the sesquiterpene lactone cnicin (1) and seven flavonoids: apigenin (2), isokaempferide ...
A new triterpenoid saponin from the aerial parts of Cephalaria ambrosioides
(Taylor & Francis Ltd, Abingdon, 2010)
A new allose-containing triterpenoid saponin (1), along with a known saponin (2), were isolated from the aerial parts of Cephalaria ambrosioides. Their structures were determined by spectroscopic (2D-NMR and ESI-MS) methods. ...
Composition of the essential oil of Ptilostemon gnaphaloides
(Springer, New York, 2008)
5,10:13,14-Disecosteroids: novel modified steroids containing 10- and 9-membered rings
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
In this paper a synthetic pathway to the modified 5,10:13,14-bisfragmentation cholestane derivatives 8-14 is described. The synthesis involves introduction of the 5α- and 14α-hydroxyl groups in the cholestane molecule and ...
