Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...
Double-layer bioactive glass coatings obtained by pulsed laser deposition
(Trans Tech Publications Ltd, Durnten-Zurich, 2008)
Pulsed laser deposition was used to obtain functionally graded bioactive glass coatings on titanium substrates. An UV KrF* (lambda=248 nm, tau gt 7 ns) excimer laser was used for the multi-pulse irradiation of the targets. ...

(Društvo inženjera plastičara i gumara, Beograd, 2009)
Hipol a.d. is one of the nine participating companies in the Cleaner Production Project 2008-1. Some of the implemented options in this factory are shown and described in this paper, with the total income of the Project ...
Influence of the background electrolyte on the point of zero charge of chromium(III)-oxide
(Trans Tech Publications Ltd, Durnten-Zurich, 2003)
The Point of zero charge of chromium(Ill)-oxide (pH(pzc)) was investigated by a batch equilibration method. The effect of several background electrolytes, in the concentration range of 10(-5)-10(-1) mol/dm(3), on pH(pzc) ...
A correlation for heat of vaporization of pure compounds
(Korean Institute Chemical Engineers, Seoul, 2008)
Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended ...
Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures - Part II
(Taylor & Francis Ltd, Abingdon, 2006)
The excess molar volume (V-E) data of the 24 binary highly non-ideal mixtures containing dicyclic ethers ( 593 data points) were correlated by the Peng - Robinson - Stryjek - Vera (PRSV) cubic equation of state (CEOS) ...
Characterization and antimicrobial activity of bacteriocin 217 produced by natural isolate Lactobacillus paracasei subsp paracasei BGBUK2-16
(Int Assoc Food Protection, Des Moines, 2004)
The strain Lactobacillus paracasei subsp. paracasei BGBUK2-16, which was isolated from traditionally homemade white-pickled cheese, produces bacteriocin 217 (Bac217; similar to7 kDa). The onset of Bac217 biosynthesis was ...
Determination of thermodynamic properties of macroporous glycidyl methacrylate-based copolymers by inverse gas chromatography
(Wiley, Hoboken, 2005)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) was synthesized by suspension copolymerization and modified by ring-opening reaction of the pendant epoxy groups with ethylene ...
Synthesis, structure and solvatochromism of 5-methyl-5-(3-or 4-substituted phenyl)hydantoins / Sinteza, struktura i solvatohromizam 5-metil-5-(3- ili 4-supstituisanih fenil)-hidantoina
(Serbian Chemical Society, Belgrade, 2009)
Several 5-methyl-5-(3- or 4-substituted phenyl)hydantoins were prepared and their ultraviolet absorption spectra were recorded in the region 200-400 nm in twelve solvents of different polarity. The effect of solvent ...
Saturated-liquid heat capacity calculation of alkanes / Predskazivanje toplotnog kapaciteta zasićene tečnosti alkana
(Serbian Chemical Society, Belgrade, 2005)
An empirical model for the calculation of the heat capacity of alkanes is recommended. This model was tested and compared to known models (Luria-Benson and Růžička-Domalski) using 68 sets with 1155 literature experimental ...
