Immobilization of dextransucrase on functionalized TiO2 supports
(Elsevier Science Bv, Amsterdam, 2018)
The TiO2 based hybrid supports with different functional groups (amino, glutaraldehyde or epoxy) were prepared and their influence on immobilization of dextransucrase (DS) was studied. Novel synthetic route for surface ...
Synthesis, characterization and electrocatalytical behavior of Nb-TiO2/Pt nanocatalyst for oxygen reduction reaction
(Elsevier, 2010)
In order to point out the effect of the support to the catalyst for oxygen reduction reaction nano-crystalline Nb-doped TiO2 was synthesized through a modified sol-gel route procedure. The specific surface area of the ...
Three-stage integration system with solid oxide fuel cell, alkali metal thermal electric converter and organic Rankine cycle for synergistic power generation
(Elsevier Ltd., 2023)
During operation, solid oxide fuel cell releases quite a great part of hydrogen energy into waste heat, leading to energy waste and even functional component degradation. In this study, solid oxide fuel cell, alkali metal ...
alpha-Tricalcium phosphate/fluorapatite based composite cements: Synthesis, mechanical properties, and biocompatibility
(Elsevier Sci Ltd, Oxford, 2020)
Composite cements based on alpha-tricalcium phosphate (alpha-TCP) and nanostructured fluorapatite (FAp), alpha-TCP/FAp, appropriate for dental usage as root canal filling material, have been prepared with the improved ...
The effect of T4 heat treatment on the microstructure and corrosion behaviour of Zn27Al1.5Cu0.02Mg alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of heat treatment on the microstructure and corrosion behaviour of Zn27Al1 5CuO 02Mg alloy was examined The alloy was prepared by melting and casting route and then thermally processed (T4 regime) Corrosion ...
Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier Science Sa, Lausanne, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was ...
Novel antimicrobial nanocomposite based on polypropylene non-woven fabric, biopolymer alginate and copper oxides nanoparticles
(Elsevier, Amsterdam, 2020)
The objective of this study was to develop novel antimicrobial nanocomposite material based on polypropylene (PP) non-woven fabric, biopolymer alginate and copper oxides nanoparticles. In order to introduce polar groups ...
Decrease of free fatty acid content in vegetable oil using silica supported ferric sulfate catalyst
(Elsevier Sci Ltd, Oxford, 2012)
A difficulty of biodiesel synthesis based on alkaline catalysts obviously exists if free fatty acids (FFAs) content in vegetable oil is above 0.5 wt.%. In this study, the ferric sulfate supported on silica (Fe-2(SO4)(3)/SiO2) ...
Thermal properties of textile fabrics made of natural and regenerated cellulose fibers
(Elsevier Sci Ltd, Oxford, 2008)
Cotton (cellulose) and viscose (regenerated cellulose) fibers are commonly applied in clothing textile fabrics. Thanks to the unique hemp (lignocellulose) fibre properties and its ecological benefits (biodegradability), ...
