Quality of chemically modified hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
Hemp fibers are very interesting natural material for textile and technical applications now. Applying hemp fibers to the apparel sector requires improved quality fibers. In this paper, hemp fibers were modified with sodium ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier Science Sa, Lausanne, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
Modulated interference effect by ZnS nanoparticles / 3-Mercaptopropyltrimethoxysilane quasi core-shell structure: Far-infrared spectroscopy
(National Institute of Optoelectronics, 2022)
The ZnS nanoparticles, as starting materials in the present study, were synthesized mechanochemically. Surface modification of the obtained nanoparticles was performed by 3-Mercaptopropyltrimethoxysilane. SEM analysis ...
Equilibrium and kinetics study on hexavalent chromium adsorption onto diethylene triamine grafted glycidyl methacrylate based copolymers
(Elsevier Science Bv, Amsterdam, 2012)
Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated ...
Welded joint geometry effect on fatigue crack growth resistance in different metallic materials
(International Journal of Fatigue, 2021)
Fatigue crack growth through different welded joint regions was investigated, in terms of welded joint geometry and fatigue crack position. In the first phase of investigation, numerical simulation of crack growth in a ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Assessment of the impact of geographical factors on the spatial distribution of heavy metals in soils around the steel production facility in Smederevo (Serbia)
(Elsevier Sci Ltd, Oxford, 2014)
The concentration of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the steel production facility in Serbia was determined to assess the contribution of emissions to pollution. ...
Determination of thermodynamic interactions of polylactide and biphasic calcium phosphate/polylactidecomposite by inverse gas chromatography at infinite dilution
(Springer, New York, 2014)
Inverse gas chromatography at infinite dilution was applied to determine the thermodynamic interactions of poly(l-lactide) (PLLA) and the composite of biphasic calcium phosphate and PLLA (BCP/PLLA). The specific retention ...
Building a Sustainable Water Management System in the Republic of Serbia: Challenges and Issues
(Amer Chemical Soc, Washington, 2015)
The Republic of Serbia is a good example of a developing country with a water management system that has not been adequately transitioned to address the need of the new socio-economic paradigm. Consequently, more than 30% ...
Diagnostic spectroscopic and computer-aided evaluation of malignancy from UV/VIS spectra of clear pleural effusions
(Elsevier, Amsterdam, 2014)
The automated, computer-aided method for differentiation and classification of malignant (M) from benign (B) cases, by analyzing the UV/VIS spectra of pleural effusions is described. It was shown that by two independent ...
