Isolation and partial characterization of protease from Pseudomonas aeruginosa ATCC 27853 / Izolovanje i delimično karakterisanje proteaze iz Pseudomonas aeruginosa ATCC 27853
(Serbian Chemical Society, 2010)
Enzymatic characteristics of a protease from a medically important, referent strain of Pseudomonas aeruginosa ATCC 27853 were determined. According to sodium dodecyl sulfate polyacrylamide gel electrophoresis, SDS-PAGE, ...
Stereoselective cyclo-addition reactions of azomethine ylides catalysed by in situ generated Ag(I)/bisphosphine complexes / Stereoselektivne cikloadicione reakcije azometinskih ilida katalizovane in situ generisanim Ag(I)/bisfosfinskim kompleksima
(Srpsko hemijsko društvo, Beograd, 2010)
Stereoselective cyclo-addition reactions of azomethine ylides promoted by in situ generated Ag(I)/bisphosphine complexes were studied. Under the optimized conditions, the pyrrolidine products were isolated in up to 84 % ...
Differences in the electrochemical behavior of ruthenium and iridium oxide in electrocatalytic coatings of activated titanium anodes prepared by the sol-gel procedure / Razlike u elektrohemijskom ponašanju oksida rutenijuma i iridijuma u elektrokatalitičkim prevlakama aktiviranih titanskih anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2010)
The electrochemical characteristics of Ti0.6Ir0.4O2/Ti and Ti0.6Ru0.4O2/Ti anodes prepared by the sol-gel procedure from the corresponding oxide sols, obtained by force hydrolysis of the corresponding metal chlorides, were ...
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 ...
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 ...
A study of the catalytic role of a gold electrode in the electrochemical activation of four macrolide antibiotics in sodium bicarbonate solution / Ispitivanje katalitičke uloge elektrode od zlata u elektrohemijskoj aktivaciji četiri makrolidna antibiotika u natrijum-bikarbonatnom elektrolitu
(Association of the Chemical Engineers of Serbia, 2010)
Using the cyclic voltammetry, it has been shown that hydrogen evolution at a gold electrode is necessary in the electrochemical activation of azithromycin dihydrate and erythromycin A. After four hours of the potential ...
Modified bentonite as adsorbent and catalyst for purification of wastewaters containing dyes / Modifikovani bentonit kao adsorbent i katalizator za prečišćavanje otpadnih voda koje sadrže boje
