Immobilization of invertase on a new type of macroporous glycidyl methacrylate
(Kluwer Academic Publ, Dordrecht, 2001)
Invertase was immobilized via its carbohydrate moiety. The immobilized enzyme has a specific activity of 5500 IU g(-1), with 45% activity yield on immobilization. In a packed bed reactor, 90% 2.5 M sucrose was converted ...
Decontamination of alkyd-carbamide paints on metals, contaminated by highly toxic compounds / Dekontaminacija alkidno-karbamidnih boja na metalu kontaminiranih visokotoksičnim jedinjenjima
(Vojnotehnički institut, Beograd, 2001)
The paper investigates rates of sorption and desorption of 2,2'-dichlordi-ethylsulphide (sulphur yperite), 1,2,2-trimethylpropyl-methylfluorophosphonate (soman), soman viscous recipe and O-ethyl-S-(2-diisopropyIamino-ethyl) ...
Synthesis and characterization of thermoplastic poly(ester-siloxane)s
(Wiley-Blackwell, 2001)
Two series of thermoplastic poly (ester-siloxane)s, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) as the hard segment, were synthesized by two-step catalyzed transesterification ...
Second harmonic generation at the quantum-interference induced transparency in semiconductor quantum wells: The influence of permanent dipole moments
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2001)
The influence of permanent dipole moments of quantized states on intersubband second harmonic generation based on quantum-interference induced transparency in semiconductor quantum wells is explored using the harmonic ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of the Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...

HPLC behavior and hydrophobic parameters of some anilides
(Springer Heidelberg, Heidelberg, 2001)
The chromatographic behavior of para substituted anilides of 2,2-dimethylpropanoic, benzoic and alpha -phenyl acetic acid has been studied by reversed-phase high performance liquid chromatography HPLC was performed on a ...
Characterization of aged elastic explosives based upon pentrite and polyurethane binder by differential scanning calorimetry and infrared spectrophotometry / Ispitivanje starenih elastičnih eksploziva na bazi pentrita i poliuretanskog veziva diferencijalnom skenirajućom kalorimetrijom i infracrvenom spektrofotometrijom
(Vojnotehnički institut, Beograd, 2001)
Elastic explosives, based upon two types of binder antioxidants, were artificially aged at 60 and 80°C, and in cycles at -30 and +60°, during four months. The aging effects on the samples of elastic explosives were examined ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(Kluwer Academic Publ, Dordrecht, 2001)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Serbian Chemical Society, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
