Aramid composites impregnated with different reinforcement: Nanofibers, nanoparticles and nanotubes / Aramidni kompoziti impregnisani sa različitim ojačanjima - nanovlakna, nanočestice i nanocevi
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
In this study, the electrospun nanofibers, nanoparticles and nanotubes were used as reinforcement in order to improve mechanical properties of materials for ballistic protection. The samples of polyurethane/p-aramid ...
The influence of triangular silver nanoplates on antimicrobial activity and color of cotton fabrics pretreated with chitosan
(Springer, New York, 2014)
The effect of cotton fabric pretreatment with biopolymer chitosan (CHT) on deposition of colloidal triangular silver nanoplates was studied. Also, the influence of deposited silver nanoparticles on color and antimicrobial ...
Discrimination between adsorption isotherm models based on nonlinear frequency response results
(Springer, Dordrecht, 2014)
A number of criteria are established for distinguishing between different adsorption isotherm types. These criteria are defined based on the adsorption isotherm derivatives up to the third order, which, on the other hand, ...
Silver film on nanocrystalline TiO2 support: Photocatalytic and antimicrobial ability
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Nanocrystalline TiO2 films were prepared on glass slides by the dip coating technique using colloidal solutions consisting of 4.5 nm particles as a precursor. Photoirradiation of nanocrystalline TiO2 film modified with ...
Influences of synthesis methods and modifier addition on the properties of Ni-based catalysts supported on reticulated ceramic foams
(Springer, New York, 2014)
A method of synthesizing Ni-based catalysts supported on alpha-Al2O3-based foams was developed. The foams were impregnated with aqueous solutions of metal chlorides under an air atmosphere using an aerosol route. Separate ...
Synthesis, structure and solvatochromic properties of novel dyes derived from 4-(4-nitrophenyl)-3-cyano-2-pyridone
(Elsevier, Amsterdam, 2014)
A series of ten new 5-arylazo-6-hydroxy-4-(4-nitrophenyl)-3-cyano-2-pyridone dyes was synthesized using a classical reaction for the synthesis of azo compounds. The structure of the dyes was confirmed by melting point, ...
Antioxidant properties of the anthocyanin-containing ultrasonic extract from blackberry cultivar "Cacanska Bestrna"
(Elsevier, Amsterdam, 2014)
For the first time, an ultrasound-assisted extraction was used to investigate isolation of anthocyanin-containing extracts from the blackberry cultivar "Cacanska Bestrna" widely grown in Serbia. Sonication time and temperature ...
Production of lactic acid and microbial biomass on distillery stillage by using immobilized bacteria / Proizvodnja mlečne kiseline i bakterijske biomase na destilerijskoj džibri pomoću imobilisanih bakterija
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2014)
Lactic acid is versatile chemical with a wide range of applications in chemical, food, pharmaceutical, cosmetic and polymer industries. Currently, lactic acid world consumption is continually increasing mostly due to ...
Kinetics of Heterogeneous Biodiesel Synthesis Using Supported ZnO as Catalyst
(Wiley-VCH Verlag Gmbh, Weinheim, 2014)
A heterogeneous catalyst, ZnO supported on alumina/silica, was synthesized by the sol-gel method. The prepared catalysts were employed for methanolysis of sunflower oil. Effects of various supports as well as calcination ...
Fabrication and behaviour of Al-Si/SiC composite in cavitation conditions
(Taylor & Francis Ltd, Abingdon, 2014)
Aluminium matrix composite (AMC) specimens were prepared using the compocasting technique. The reinforcements used were silicon carbide (SiC) particles with an average size of 30 mm. The influence of reinforced ratio of ...
