Obtaining of high quality cellulose from the hemp fibers / Dobijanje visoko kvalitetne celuloze iz vlakana konoplje
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
In recent years growing attention has been paid to production of cellulose from unconventional, annually and renewable plants such as hemp and flax. Lignin and pectin are very important noncellulosic substances occurring ...
Amtimicrobial activity of essential oil of Melissa officinalis L., Lamiaceae / Antimikrobna aktivnost etarskog ulja Melissa officinalis L., Lamiaceae
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
The antimicrobial activity of the essential oil of Melissa officinal is 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 ...
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 ...
Comparative potentiodynamic study of nickel and hydrogen underpotential deposition at polycrystalline platinum electrode in weak acid and neutral solutions
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Underpotential deposition of nickel and hydrogen on polycrystalline platinum in weak acid and neutral solutions (3.5 lt = pH lt = 7.0), with and without Ni2+-ions, has been examined using cyclic voltammetric technique ...
Electrothermal desorption in an annular-radial flow - ACFC adsorber - Mathematical modeling
(Springer, New York, 2005)
A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic ...
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 ...
In situ stabilization of toxic metals in polluted soils using phosphates: theoretical prediction and experimental verification
(Elsevier, Amsterdam, 2005)
The in situ (in place) immobilization of toxic metals, using inexpensive "reactive" amendments, is considered as a simple and cost-effective approach for the treatment of soils, contaminated by the presence of heavy metals, ...
Composition and antimicrobial activity of essential oil of Satureja montana L. collected in Serbia and Montenegro
(Allured Publ Corp, Carol Stream, 2005)
The chemical composition of the essential oil of Satureja montana L. subsp. montana (Lamiaceae), obtained from the air-dried plant material by hydrodistillation, was analyzed using GC and GUMS. The major components were ...
