The influence of acid treatment on the nanostructure and textural properties of bentonite clays
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The nanostructure and textural properties of acid-activated bentonite clays from the Bogovina coalmine were investigated. The acid activation was performed with HCl in the concentration range 1.5-7.5 M. The atomic force ...
Slow-wave EBG microstrip rat-race hybrid ring
(Iee-Inst Elec Eng, Hertford, 2005)
A new type of slow-wave EBG microstr p rat-race hybrid ring is presented. It effectively reduces the occupied area to 11% of the conventional rat-race hybrid ring. It does not need any impedance transformers on the ports.
Inhibition effects in the partial oxidation of cyclohexane on polymer supported Co(II) catalysts / Efekti inhibicije u parcijalnoj oksidaciji cikloheksana Co(II) katalizatorima nanetim na polimerni nosač
(Serbian Chemical Society, 2005)
Polymer supported catalysts with different contents of metal ions where synthesized by wet impregnation of the degassed support from ethanolic solutions of cobalt(II) nitrate. Amacroreticular copolymer of poly-4-vinylpyridine ...
Characterization of enzymatically synthesized diferulate
(New York Acad Sciences, New York, 2005)
Horseradish peroxidase was used to synthesize diferulates by a procedure in which ethyl ferulate was used as substrate. Four different forms were obtained, of which two dominant were the 5-5' and 8-5' diferulate. Fluorescence ...
Magnetic properties of ND Rich Melt-Spun ND-FE-B alloy
(International Institute for the Science of Sintering, Beograd, 2005)
As a part of these experimental investigations of melt-spun Nd-Fe-B alloy with Nd rich content in relation to Nd2Fe14B prepared by rapid quenching process for optimally selected cooling rate and heat treatment, the influence ...
Differentiation of the contribution of local resuspension from that of regional and remote sources on trace elements content in the atmospheric aerosol in the Mediterranean area
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
For the determination of effects of contaminated crude soil on the content of trace elements in the atmospheric aerosol, trace elements in crude soil samples from within the area of influence of local resuspension were ...
Characterization of glycidyl methacrylate based copolymers by inverse gas chromatography under finite surface coverage
(Wiley-V C H Verlag Gmbh, Weinheim, 2005)
Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl ...
Characterization and catalytic activity of poly(4-vinylpyridine-co-divinylbenzene)-Co2+ complex
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravinietric analysis (TG-DTA), N-2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...
