Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
Influence of gamma radiation on measurement fast pulse voltages by Kerr electro-optic effect
(Radiation Effects and Defects in Solids, 2021)
In this paper, the possibility of measuring the electronic pulse from an electronic generator for plasma heating by electro-optical method is considered. The experiments are performed by applying the Kerr effect on an ...
Preparation and properties of hydrogen peroxide oxidized starch for industrial use
(Savez hemijskih inženjera, Beograd, 2020)
Oxidized starch, an additive used in paper manufacturing and products for construction industry, is usually produced using harmful oxidant, such as hypochlorites or periodates. In this study, a simple and efficient ...
Zinc oxide nanoparticles prepared by thermal decomposition of zinc benzenepolycarboxylato precursors: Photoluminescent, photocatalytic and antimicrobial properties / Наночестични прахови цинк-оксида добијени термичком деградацијом цинк-бензенполикарбоксилато прекурсора: фотолуминесцентна, фотокаталитичка и антимикробна својства
(Serbian Chemical Society, 2020)
Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-source precursors at 450 °C in an air atmosphere. The mechanism and kinetics of thermal ...
Structural and surface modification of highly ordered alumina for enhanced removal of Pb2+, Cd2+ and Ni2+ from aqueous solution
(Desalination Publ, Hopkinton, 2020)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) alumina doped with iron oxide, and subsequently modified with (3-aminopropyl)triethoxysilane (APTES), FeAl2O3 and FeAl(2)O(3)APTES, was used for ...
Adsorption performances and antimicrobial activity of the nanosilver modified montmorillonite clay
(Desalination Publ, Hopkinton, 2020)
The synthesis and adsorption potential of Cy-npAg, obtained by modification of raw montmorillonite clay (raw-Cy) with silver nanoparticle (npAg), was studied in this work. Optimization procedure, with respect to time, ...
Phase composition of Bi2O3 specimens doped with Ti, Zr and Hf
(Belgrade : Serbian Chemical Society, 2012)
Powder mixtures of α-Bi2O3 containing 2, 5 and 10 mole % of TiO2, ZrO2 or HfO2 were homogenized, heated at 820ºC for 24 h and quenched in air. X-ray powder diffraction technique was used to characterize the prepared samples. ...
Metallic ion release from biocompatible cobalt-based alloy / Otpuštanje metalnih jona iz biokompatibilne legure kobalta
(Association of the Chemical Engineers of Serbia, 2014)
Metallic biomaterials, which are mainly used for the damaged hard tissue replacements, are materials with high strength, excellent toughness and good wear resistance. The disadvantages of metals as implant materials are ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Sorption of different phenol derivatives on a functionalized macroporous nanocomposite of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite
(Serbian Chemical Society, 2014)
Macroporous nanocomposite of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) and acid modified bentonite was prepared by radical suspension copolymerization. Nanocomposite was functionalized with diethylenetriamine ...
