The effect of the particle shape and structure on the flowability of electrolytic copper powder I: Modeling of a representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha I - modelovanje reprezentativne čestice praha
(Serbian Chemical Society, 2003)
One of the most important properties of copper powder is its flow ability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
Evaluation of antioxidative effects of twelve 3-substituted-5,5-diphenylhydantoins on human colon cancer cell line HCT-116
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2013)
Antioxidant effects of twelve 3-substituted-5,5-diphenylhydantoins in concentrations of 0.01, 0.1, 1, 10, and 100 mu M on human colon cancer cell line HCT-116 were determined 24 h after treatment. The concentrations of ...
Rhamnolipid and lipase production by Pseudomonas aeruginosa san-ai: The process comparison analysis by statistical approach / Proizvodnja ramnolipida i lipaze iz Pseudomonas aeruginosa san-ai - optimizacija procesa primenom metode odzivnih površina
(Association of Chemical Engineers of Serbia, 2013)
Pseudomonas aeruginosa has been repeatedly reported as a powerful producer of rhamnolipid biosurfactants as well as hydrolytic enzymes. In this study, the effects of four fermentation factors were evaluated using response ...

(University of Belgrade, Technical Faculty, Bor, 2003)
Paper presents a thermodynamic analysis of chemical reactions occurring during chlorination with and without additives for both nickel oxides and nickel ferrites, which are component parts of nickel ore. The experimental ...
Alkali activated slag cement doped with Zn-rich electric arc furnace dust
(Journal of Materials Research and Technology-JMR&T, 2020)
Steel production in electric arc furnaces yielding formation of two waste materials, toxic electric arc furnace dust (EAFD) and non-hazardous electric arc furnace slag (EAFS). EAFD presents a potential hazard to the ...
The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...
Effects of operating parameters on efficiency of lead removal by complexation-microfiltration process / Uticaj radnih parametara na efikasnost uklanjanja jona olova pomoću kompleksirajuće-mikrofiltracionog procesa
(Association of Chemical Engineers of Serbia, 2012)
The majority of lead content found in the environment is a result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. A complexation-microfiltration process for the removal of Pb(II) ions ...
Antioxidative capacity of fermented red bean and its protein hydrolysate fractions / Antioksidativni kapacitet fermentisanog crvenog pasulja i njegovih proteinskih hidrolizata
