Covalent immobilization of lipase from Candida rugosa on Eupergit® / Kovalentna imobilizacija lipaze iz Candida rugosa za Eupergit®
(Faculty of Technology, Novi Sad, 2005)
An approach is presented for the stable covalent immobilization of Upase from Candida rugosa on Eupergit® with a high retention of hydrolytic activity. It comprises covalent bonding via lipase carbohydrate moiety previously ...
Microwaves in organic chemistry and organic chemical / Primena mikrotalasne tehnike u organskoj hemiji i organskoj hemijskoj tehnologiji
(Association of Chemical Engineers of Serbia, 2005)
The usual way of applying heat to a chemical reaction is the use of a Bunsen burner, an oil or some other type of bath, or an electric heater. In inorganic chemistry, microwave technology has been used since the late 1970s ...
Kovats retention index-boiling point relationship of 2-phenyl-2-alkyl-acetonitriles on stationary phases of different polarity / Zavisnost kovačevog retencionog indeksa od temperature ključanja 2-fenil-2-alkilacetonitrila na stacionarnim fazama različite polarnosti
(Association of the Chemical Engineers of Serbia, 2005)
Linear and reciprocial Kovats retention index-boiling point relationships known from the literature were used to study the Kovats retention index-boiling point dependence of 2-phenyl-2-alkylacetonitriles on stationary ...
Electrochemical deposition and characterization of zinc-nickel alloys deposited by direct and reverse current / Elektrohemijsko taloženje i karakterizacija legura cink-nikal dobijenih konstantnom i reversnom strujom
(Serbian Chemical Society, Belgrade, 2005)
Zn-Ni alloys electrochemically deposited on steel under various deposition conditions were investigated. The alloys were deposited on a rotating disc electrode and on a steel panel from chloride solutions by direct and ...
AFM studies of DNA structures extracted from adriamycin treated and non-treated Ehrlich tumor cells
(Srpsko hemijsko društvo, Beograd, 2005)
Atomic force microscopy (AFM), a unique tool to investigate drug treatment of cancer cells, was used to analyze the anti-neoplastic activity of adriamycin by comparing DNA structures of non-treated and adriamycin-treated ...
Initiation of MMA polymerization by iniferters based on dithiocarbamates / Iniciranje polimerizacije metilmetakrilata iniferterima na bazi ditiokarbamata
(Association of Chemical Engineers of Serbia, 2005)
Twelve modified dithiocarbamates and a thiuramdisulfide used for the initiation of methyl methacrylate (MMA) polymerization were synthesized in this study. The polymerization of MMA was followed by determine the yield and ...
Uticaj gustine izmene za procese taloženja na nastajanje tankog površinskog sloja metala na nesrodnoj podlozi
(Engineering Society for Corrosion, Belgrade, Serbia, 2005)
Electroplating could be defined as a group of procedures in which metal surfaces (sometime nonmetals) transforms, so the surface properties are changed from base materials to the deposited metal. This goal can be achieved ...
Amtimicrobial activity of essential oil of Melissa officinalis L, Lamiaceae / Antimikrobna aktivnost etarskog ulja Melissa officinalis L, Lamiaceae
(Association of Chemical Engineers of Serbia, 2005)
The antimicrobial activity of the essential oil of Melissa officinalis was investigated in this paper. The essential oil was obtained by the principle of water and steam and analyzed by GC and GC-MS using FID and MSD. The ...
