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 ...
The influence of the parameters of lost foam process on the quality of aluminum alloys castings / Uticaj parametara lost foam procesa na kvalitet odlivaka legura aluminijuma
(Association of Chemical Engineers of Serbia, 2010)
This paper presents the research results of application of Lost foam process for aluminum alloys castings of a simple geometry. The process characteristic is that patterns and gating of moulds, made of polymers, stay in ...
Optimization of preparation conditions of poly(ε-caprolactone) microspheres for controlled release of carbamazepine / Optimizacija uslova dobijanja mikrosfera na bazi biodegradabilnog poli(ε-kaprolaktona) za kontrolisano otpuštanje karbamazepina
(Association of Chemical Engineers of Serbia, 2010)
Poly (ε-caprolactone), PCL, is an aliphatic polyester suitable for controlled drug release due to its biodegradability, biocompatibility, non-toxicity and high permeability to many therapeutic drugs. This study investigates ...
Solvent effects on photodegradation of CI Reactive Orange 16 by simulated solar light / Uticaj rastvarača na fotodegradaciju sintetske boje Reactive Orange 16 pomoću simulirane sunčeve svetlosti
(Association of Chemical Engineers of Serbia, 2008)
Organic solvents may appear in wastewaters and other industrial waste streams containing dyes, therefore, their photodegradation catalyzed by TiO2 should be investigated. Solvent effect on photodegradation of CI Reactive ...
Antimicrobial activity of hybrid hydrogels based on poly(vinylpyrrolidone) containing silver / Antimikrobna aktivnost hibridnih hidrogelova na bazi poli(vinilpirolidona) koji sadrže srebro
(Association of Chemical Engineers of Serbia, 2010)
New hybrid hydrogels were prepared by radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid, poly(vinylpyrrolidone) and silver salt. FTIR spectroscopy has confirmed binding of silver particles in hydrogels. ...
The peculiarities of electrochemical deposition and morphology of Zn-Mn alloy coatings obtained from pyrophosphate electrolyte / Specifičnosti elektrohemijskog taloženja i morfologija Zn-Mn prevlaka dobijenih iz pirofosfatnog elektrolita
(Association of Chemical Engineers of Serbia, 2011)
The first successful attempt to electrodeposit Zn-Mn alloy coatings from alkaline bath was made only a few years ago. In this kind of solution, potassium pyrophosphate (K4P2O7) serves both as a complexing agent and as the ...
