Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier Science Sa, Lausanne, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane. By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal analysis it was shown ...
Optimization of modifier deposition on the alumina surface to enhance mechanical properties and cavitation resistance
(Springer, New York, 2020)
Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with ...
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 ...
Closing the Loop: Dyeing and Adsorption Potential of Mulberry Wood Waste
(Journal of Natural Fibers, 2022)
This study reports the successful transformation of mulberry wood waste into natural textile dye and adsorbent for Pb2+ ions from an aqueous solution. Fabrics of different chemical compositions were dyed using mulberry ...
Crystallization behavior of alkoxy-derived cordierite gels
(Springer, New York, 2003)
Alkoxy-derived cordierite gels were synthesized from tetraethylorthosilicate (TEOS), aluminum isopropoxide (Al(OPri)(3)), and magnesium ethoxide (Mg(OEt)(2)). TEOS was partially hydrolyzed at molar ratios H2O/TEOS=1.2, in ...
Silicon-doped biphasic alpha-calcium-phosphate/hydroxyapatite scaffolds obtained by a replica foam method using uniform pre-annealed spherical particles
(Elsevier Science Bv, Amsterdam, 2012)
In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds ...
Development of low calorie jams with increased content of natural dietary fibre made from tomato pomace
(Elsevier Sci Ltd, Oxford, 2017)
In this study, four jam formulations were developed, starting with the basic formulation (Jam 1) containing sucrose and without added pectin. Sucrose was partially (50%) replaced by stevioside in formulations of Jam 2 and ...
