An overstoichiometric Nd-Fe-B hard magnetic material / Nadstehiometrijski Nd-Fe-B tvrdi magnetni materijali
(Serbian Chemical Society, 2010)
A commercial Nd-rich Nd-Fe-B-based hard magnetic material was studied. The obtained results were compared before and after recording of the thermomagnetic curve up to 800 °C. The curve itself showed clearly besides Curie ...
Preliminary analysis of fatty acid chemistry of Kindbergia praelonga and Kindbergia stokesii (Brachytheciaceae) / Preliminarna analiza hemije masnih kiselina vrsta Kindbergia praelonga i Kindbergia stokesii (Brachytheciaceae)
(Serbian Chemical Soc, Belgrade, 2010)
Moss species of the family Brachytheciaceae, Kindbergia praelonga (Hedw.) Ochyra and Kindbergia stokesii (Turn.) Ochyra, were preliminarily analysed for their fatty acid composition with the aim of studying the chemical ...
Pore surface fractal analysis of PEG and La(III)-doped mesoporous alumina obtained by the sol-gel method / Fraktalna analiza površine mezoporoznog aluminijum(III)-oksida sa dodatkom PEG i La(III) dobijenog sol-gel postupkom
(Serbian Chemical Society, 2010)
Active porous alumina was prepared via a sol-gel method and subjected to thermal treatment in the temperature range 500-1200 °C. The addition of lanthanum effectively inhibited the surface area loss of the aluminas. Fractal ...
Biodiesel synthesis using K2CO3/Al-O-Si aerogel catalysts / Sinteza biodizela katalizovana alumosilikatnim aerogelom sa K2Co3
(Serbian Chemical Society, 2010)
In this study, catalysts for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as the active component on an alumina/silica support were synthesized using the sol-gel method, which was followed by drying ...
n-alkanes in the needle waxes of Pinus heldreichii var. pančići / n-alkani u voskovima iglica Pinus heldreichii var. pančići
(Serbian Chemical Soc, Belgrade, 2010)
This is the first report of n-alkanes in needle epicuticular waxes of the variety Bosnian pine, Pinus heldreichii var. pančići. n-Hexane extracts of needle samples, originating from seven isolated localities in Serbia, ...
Consistent force field for metalloporphyrins / Konzistentno polje sila za metaloporfirine
(Serbian Chemical Soc, Belgrade, 2010)
Molecular mechanics (MM) calculations to analyze the puckering of metalloporphyrins isolated and adsorbed on a graphite layer (0001) as a function of metal ion size and the peripheral substitution are presented. The ...
