Tehničko rešenje koje se odnosi na primenu nanočestičnog sepiolita za poboljšanje mehaničkih svojstava papira proizvedenog u Fabrici Hartije Beograd je uspešno realizovano kroz laboratorijska ispitivanja i industrijsku ...
Characterization of the Ag43Cu37Zn20 alloy surface after potentiostatic polarization using LDI-TOF mass spectrometry
(Walter de Gruyter Gmbh, 2017)
This work is the first to demonstrate the possibilities of direct analysis of the corrosion film formed on Ag43Cu37Zn20 alloy using laser desorption/ionization (LDI) on a commercial matrix-assisted LDI time of flight mass ...
Design and characterization of alcalase-chitosan conjugates as potential biocatalysts
(Springer, New York, 2017)
In this study, alcalase (protease from Bacillus licheniformis) immobilization by adsorption, enzyme crosslinking and covalent enzyme binding to activated chitosan microbeads were examined. The biocatalysts highest activity ...
Multifunkcionalna svojstva pamuka oksidisanog kalijum-permanganatom / Multifunctional properties of cotton oxidized with potassium permanganate
(Požarevac : Društvo hemičara, tehnologa i metalurga, 2017)
U ovom radu pamučna pređa je oksidisana kalijum-pemanganatom (KMnO4) pri različitim pH vrednostima i različitim koncentracijama na sobnoj temperaturi. Oksidacija je vršena u cilju čišćenja pamučnih vlakana i uvođenja ...

(Springer, New York, 2017)
The aim of this study was to develop simple and efficient method for immobilization of Candida antarctica lipase B onto hydrophobic anion exchange resin Purolite(A (R)) MN102 and to apply immobilized catalyst for the ...
Merits and demerits of different methods for radon exhalation measurements for building materials
(RAD Association, 2017)
With an increase in the awareness of the need to save energy, residents tend to live in dwellings with increasingly tight windows and doors, thus reducing the ventilation rate of indoor air which leads to an increased ...
The removal of cationic dye from water by adsorption on sepiolite
(Međunarodnog stručno-naučnog skupa Vodovod i kanalizacija, 2017)
Boje se iz otpadnih voda uklanjaju razlicitim fizickim, hemijskim i bioloskim postupcima, medu kojima adsorpcija ima veliki znacaj. Medu brojnim materijalima koji se poslednjih godina ispituju kao moguci adsorbenti za boje, ...
ZnO nanopowders obtained by thermolysis of zinc benzenedicarboxylate complexes with 2,2’-dipyridylamine
