The influence of silicon substitution on the properties of spherical- and whisker-like biphasic alpha-calcium-phosphate/hydroxyapatite particles
(Springer, Dordrecht, 2011)
In this work, the influence of the morphology of hydroxyapatite particles on silicon substitution through hydrothermal synthesis performed under the same conditions was investigated. Spherical- and whisker-like hydroxyapatite ...
Multifunctional Properties of Polyester Fabrics Modified by Corona Discharge/Air RF Plasma and Colloidal TiO2 Nanoparticles
(Wiley, Hoboken, 2011)
In this study the possibility of tailoring the textile nanocomposite materials based on the polyester fabric and TiO2 nanoparticles that can simultaneously provide desirable level of antibacterial activity, UV protection, ...
Behaviour of small cracks during their propagation from Vickers indentations in coarse-grain steel: An experimental investigation
(Elsevier Sci Ltd, Oxford, 2011)
In this investigation we look at the influence of the local residual stresses caused by Vickers-pyramid indenting on the initiation and early propagation of small cracks from indentations in coarse-grain martensitic steel. ...
The effect of deposition temperature on the surface coverage and morphology of iron-phosphate coatings on low carbon steel
(Elsevier, Amsterdam, 2011)
The influence of deposition temperature and concentration of NaNO2 in the phosphating bath on the surface morphology and coverage of iron-phosphate coatings on low carbon steel was investigated. The phosphate coatings were ...
Surface Characterization of Iron-Modified Sepiolite by Inverse Gas Chromatography
(Amer Chemical Soc, Washington, 2011)
Inverse gas chromatography at infinite and finite surface coverages was applied to evaluate the surface properties of an iron-modified sepiolite sorbent, Fe-sepiolite. The adsorptions of different nonpolar and polar probes ...
Oxidized Hemp Fibers with Simultaneously Increased Capillarity and Reduced Moisture Sorption as Suitable Textile Material for Advanced Application in Sportswear
(Fibers and Polymers, 2021)
Applications of hemp fibers, as a promising natural material in the textile field, mostly require improved fiber properties. In this paper, the oxidation of hemp fibers with potassium permanganate was applied to reduce the ...
Enhanced ammonia synthesis in multifunctional reactor with in situ adsorption
(Elsevier, Amsterdam, 2011)
A steady-state, one-dimensional mathematical model for a multifunctional reactor with in situ adsorption for ammonia synthesis is developed. The model represents integrated ammonia catalytic equilibrium reaction with ammonia ...
Strain hardening of austenite in Fe-Cr-C-V alloys under repeated impact
(Elsevier Science Sa, Lausanne, 2011)
Structural changes were analyzed in Fe-Cr-C-V alloy balls with high chromium and different vanadium content, after repeated impact load testing. The results indicate that plastic deformation and strain hardening occur in ...
Adsorption of chromium (VI) from aqueous solutions onto amine-functionalized natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2013)
Chromium(VI) adsorption onto amine-functionalized sepiolites from aqueous solution at 298 K was investigated. Natural and add-activated sepiolites were functionalized by covalent grafting [3-(2-aminoethylamino)propyl] ...
Ethanol influenced fast microwave-assisted extraction for natural antioxidants obtaining from spent filter coffee
(Elsevier, Amsterdam, 2013)
Ethanol influenced microwave-assisted extraction was performed for obtaining of natural antioxidants from spent filter coffee. The process included response surface methodology which represented the significance of both ...
