A study of the photocatalytic degradation of methomyl by UV light
(Association of the Chemical Engineers of Serbia, 2009)
The photocatalytic degradation of insecticide methomyl in water, using TiO2 and ZnO (Merck), under UV (366 nm) was studied. The influence of the catalyst concentration and pH was investigated. The optimal concentration of ...
The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
Hydantoins: Synthesis, properties and anticonvulsant activity / Hidantoini - dobijanje, svojstva i antikonvulzivna aktivnost
(Association of Chemical Engineers of Serbia, 2009)
Hydantoin is a five-membered cyclic ureide that is present in numerous biologically active compounds including antiarrhytmics, anticonvulsants and antitumor agents. This paper describes different ways of synthesis of ...
Micromechanical and structural properties of nickel coatings electrodeposited on two different substrates / Mikromehanička i strukturna svojstva elektrodeponovanih prevlaka nikla na različitim supstratima
(Serbian Chemical Society, Belgrade, 2009)
Fine-structured nickel coatings were electrodeposited from a sulfamate-based electrolyte onto different substrates: polycrystalline cold-rolled copper and single crystal silicon with (111) orientation. The influence of the ...
The influence of bonding agents in improving interactions in composite propellants, determined using the FTIR spectra / Uticaj vezujućih agenasa na poboljšanje interakcija u kompozitnim gorivima utvrđen korišćenjem FTIR spektara
(Military Technical Institute, Belgrade, 2009)
Bonding agents synthesized in this research are 1, 3, 5-trisubstituted isocyanurates (substituents: 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl and 2, 3-epoxypropyl). All syntheses reactions were carried out according ...
Hydrometallurgical process for extraction of metals from electronic waste, Part I: Material characterization and process option selection
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling ...
The analysis of different processes of extraction: yield of extracts obtained from Aloe vera (Aloe barbadensis Miller) and sweet bay (Laurus nobilis L.) and the exergy analysis of applied processes
(Association of the Chemical Engineers of Serbia, 2009)
The present study was aimed to investigate and compare the efficiency of different methods for the isolation extract from a plant material. Extracts from dried leaves of Aloe vera (A. barbadensis Mill.) and Sweet Bay (Laurus ...
The ultrasonic and image analysis method for non-destructive quantification of the thermal shock damage in refractory specimens
(Elsevier Sci Ltd, Oxford, 2009)
In the present work, Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950 ...
Optimization of the procedure for the synthesis of calcium lactate pentahydrate in laboratory and semi-industrial conditions / Optimizacija postupka sinteze kalcijum-laktat pentahidrata u laboratorijskim i poluindustrijskim uslovima
(Association of Chemical Engineers of Serbia, 2009)
This paper is concerned on the development of the optimal laboratory procedure for the synthesis of calcium lactate pentahydrate and the application of obtained results in a project for a semi-industrial installation for ...
Design and optimization of purification procedure for biodiesel washing
(Association of the Chemical Engineers of Serbia, 2009)
Almost complete methanolysis of triglycerides is usually not enough to fulfil the strict standards of biodiesel quality. A key step in this process is neutralization of alkali (catalyst) followed by the washing procedure ...
