Biosorption as a new biotechnology with an aim of protection and balanced use of biodiversity / Biosorpcija kao nova biotehnologija u funkciji očuvanja i uravnoteženog korišćenja biodiverziteta
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2010)
Rapid techno-economic development, without adequate protection of the environment, caused a number of emergence problems: pollution, waste, loss of biodiversity, introduction of invasive species, release of o genetically ...
Non-linear frequency response analysis of the kinetics of electrochemical reactions: a case study – ferrocyanide oxidation kinetics
(Serbian Chemical Society, Belgrade, 2010)
In general, electrochemical (EC) systems are non-linear, which means they respond nonlinearly to a frequency-dependent periodic input perturbation of high amplitude imposed around a steady-state. In addition, the kinetics ...
Structural and microhardness characterization of thin electrodeposited Ni/Cu multilayers on copper substrates
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
Multilayered composite systems of alternately electrodeposited nanocrystalline Cu and Ni films on cold-rolled microcrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to ...
Effect of heating rate on precipitation of peak-aged Al-Li (8091) alloy: A quantitative approach
(Savez inženjera metalurgije Srbije, Beograd, 2010)
Samples of Al-Li (8091) alloy were solution treated at 540ºC for 30 min, water-quenched and continuously heated in oil at 0.05 and 0.1ºC/min rates, from room temperature to 190ºC when the peak hardness was achieved. Having ...
Influence of current and temperature on discharge characteristics of electrochemical nickel-cadmium system / Uticaj struje i temperature na karakteristike pražnjenja elektrohemijskog nikal-kadmijum sistema
(Association of Chemical Engineers of Serbia, 2010)
The paper elaborates determination of characteristic values in the discharging process of non-hermetic nickel-cadmium galvanic battery with nominal voltage Un = 60 V and nominal capacity qn = C5 = 190 A h and its dependence ...
Synthesis, structure and solvatochromic properties of 3-cyano-4,6-diphenyl-5-(3- and 4-substituted phenylazo)-2-pyridones / Sinteza, struktura i solvatohromna svojstva 3-cijano-4,6-difenil-5-(3- i 4-supstituisanih fenilazo)-2-piridona
(Serbian Chemical Society, Belgrade, 2010)
A series of some new pyridone arylazo dyes was synthesized from the corresponding diazonium salts and 3-cyano-4,6-diphenyl-2-pyridone using the classical reaction for the synthesis of the azo compounds. The structures of ...

Main characteristics and specifications impact of the world economic creases on the Serbian economy are studied in this chapter. Role and importance of the real sector are studied, too. Real sector, it means industry, ...
Controlled swelling and degradation studies of alginate microbeads in dilute natrium citrate solutions / Ispitivanje mogućnosti kontrolisanog bubrenja i razgradnje alginatnih mikročestica u razblaženim rastvorima natrijum-citrata
(Association of Chemical Engineers of Serbia, 2010)
Alginate hydrogels are widely used in biomedicine due to alginate availability, hydrophilic nature, biocompatibility and biodegradability. Alginate microbeads are particularly attractive for applications in pharmacy and ...
A study of the catalytic role of a gold electrode in the electrochemical activation of four macrolide antibiotics in sodium bicarbonate solution / Ispitivanje katalitičke uloge elektrode od zlata u elektrohemijskoj aktivaciji četiri makrolidna antibiotika u natrijum-bikarbonatnom elektrolitu
(Association of the Chemical Engineers of Serbia, 2010)
Using the cyclic voltammetry, it has been shown that hydrogen evolution at a gold electrode is necessary in the electrochemical activation of azithromycin dihydrate and erythromycin A. After four hours of the potential ...
