The influence of migration processes in gunpowder charge on the quality of mortar ammunition
(Savez hemijskih inženjera, Beograd, 2017)
The study describes the results of static, physicochemical and ballistic examination of double-based gunpowder charges, in order to establish the deviations from the demanded quality of mortar ammunition. The examinations ...
Crystallization and sinterability of lanthanum-strontium-borate-glass powders / Kristalizacione karakteristike i sinterabilnost prahova lantan-stroncijum-boratnih stakala
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2017)
The subject of this doctoral thesis is the study of the crystallization behavior and the sinterability of the borate glasses system La2O3-B2O3-SrO. In literature there are limited data from the crystallization characteristics ...
Investigation of Bi2O3-rich part of Bi2O3-PbO phase diagram
(Srpsko hemijsko društvo, Beograd, 2017)
A new Bi-rich part of Bi2O3-PbO phase diagram was determined using differential thermal analysis and X-ray powder diffraction techniques. Four solid solutions, alpha-Bi2O3, gamma-Bi2O3, d-Bi2O3 and ss(ss)-Bi8Pb5O17, can ...
Microencapsulation of anthocyanin-rich black soybean coat extract by spray drying using maltodextrin, gum Arabic and skimmed milk powder
(Taylor & Francis Ltd, Abingdon, 2017)
Black soybean coat is insufficiently valorised food production waste rich in anthocyanins. The goal of the study was to examine physicochemical properties of spray dried extract of black soybean coat in regard to carrier ...
Gelatin as a carrier system for delivery of polyphenols compounds / Želatin kao nosač za isporuku polifenolnih komponenata
(Savez inženjera i tehničara Srbije, Beograd, 2017)
In the present study, the influence of different encapsulation techniques (lyophilization and spray drying) on gelatin, as a carrier system for delivery of polyphenols compounds, on wild thyme extracts and on encapsulated ...
Low temperature solid-state wetting and formation of nanowelds in silver nanowires
(IOP Publishing Ltd, Bristol, 2017)
This article focuses on the microscopic mechanism of thermally induced nanoweld formation between silver nanowires (AgNWs) which is a key process for improving electrical conductivity in NW networks employed for transparent ...
Applicability of zeolites in potassium and nitrate retention in different soil types
(Srpsko hemijsko društvo, Beograd, 2017)
Environmental protection and sustainable agricultural production require the use of inexpensive and environmentally acceptable soil supplements. Objectives of this study were to investigate the influence of the addition ...
Kinetic Modeling of Secondary Methane Formation and 1-Olefin Hydrogenation in Fischer-Tropsch Synthesis over a Cobalt Catalyst
(Wiley, Hoboken, 2017)
A detailed kinetic model of Fischer-Tropsch synthesis (FTS) product formation, including secondary methane formation and 1-olefin hydrogenation, has been developed. Methane formation in FTS over the cobalt-based catalyst ...
Characterization of dextransucrase from Leuconostoc mesenteroides T3, water kefir grains isolate
(Savez hemijskih inženjera, Beograd, 2017)
The production of dextransucrase (DS) by Leuconostoc mesenteroides T3, novel isolate from water kefir grain, was studied and optimized. Bacterial supernatant reached activity of 3.1 U/ml when the culture was grown at 23 ...
Nanoscale zerovalent iron (nZVI) supported by natural and acid-activated sepiolites: the effect of the nZVI/support ratio on the composite properties and Cd2+ adsorption
(Springer Heidelberg, Heidelberg, 2017)
Natural (SEP) and partially acid-activated (AAS) sepiolites were used to prepare composites with nanoscale zerovalent iron (nZVI) at different (SEP or AAS)/nZVI ratios in order to achieve the best nZVI dispersibility and ...
