Selective magnetic GMA based potential sorbents for molybdenum and rhenium sorption
(Elsevier Science Sa, Lausanne, 2017)
Magnetic macroporous crosslinked copolymer glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) samples with different magnetite content were prepared by suspension copolymerization and functionalized ...
The comparative study of the corrosion stability of Zn-Ni-Co alloy coatings deposited from chloride and sulphate baths / Uporedna analiza korozione stabilnosti prevlaka Zn-Ni-Co legura elektrohemijski taloženih iz hloridnih i sulfatnih rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The ternary Zn-Ni-Co alloy coatings were electrodeposited on steel from chloride and sulphate baths. The deposition was carried out galvanostatically at different current densities at ambient temperatures from additives ...
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 ...
The influence of alkaline cations on the mechanism and kinetics of dehydration of polymeric phthalatocuprate(II) dihydrates
(Elsevier Science Bv, Amsterdam, 2017)
Thermal dehydration of two heterometallic complexes containing dianion of phthalic acid, pht, Na-2[Cu(pht)(2)] center dot 2H(2)O, 1, and K-2[Cu(pht)(2)] center dot 2H(2)O, 2, was investigated under non-isothermal conditions. ...
Ecological modification of polyester surface properties using plasma treatment / Ekološko modifikovanje površinskih svojstava poliestra upotrebom plazme
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2017)
During plasma treatment of polyester, the morphological structure and chemical composition of the fiber is being modified. Thereby, the surface roughening and formation of new functional groups occur. Then, the surface ...
Chemometric evaluation of binary mixtures of alginate and polysaccharide biopolymers as carriers for microencapsulation of green tea polyphenols
(Taylor & Francis Inc, Philadelphia, 2017)
In this study principal component analysis and artificial neural networks were used to evaluate the potential of using binary mixtures of sodium alginate and other polysaccharide biopolymers as the carriers for microencapsulation ...
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 ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
