Structural, Morphological and Electrical Properties of Alumina/YAG Composites as Solid Electrolyte for IT - SOFC
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Alumina/YAG composites (AYX_t) with high relative density (99.2 %TD) were successfully obtained by mixing commercial alumina powder with different volume fractions of yttrium aluminium garnet (Y3Al5O12-YAG; 7, 14, 21 and ...
Visible light absorption of TiO2 nanoparticles surface-modified with vitamin B-6: A comparative experimental and DFT study
(Srpsko hemijsko društvo, Beograd, 2018)
Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B-6) was found to alter the optical properties. Microstructural characterization ...
Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
Stability of gold complex based on mercaptotriazole in acid and neutral media
(Bulgarian Academy of Sciences, 2018)
Stability of the gold complex based on mercaptotriazole in two acid electrolytes with different pH values and in a neutral medium was investigated in this work. Investigation was performed by visual monitoring and ...
Lactic acid production on molasses enriched potato stillage by Lactobacillus paracasei immobilized onto agro-industrial waste supports
(Elsevier Science Bv, Amsterdam, 2018)
In this study, the production of lactic acid (LA) on sugar beet molasses enriched potato stillage by immobilized Lactobacillus paracasei NRRL B-4564 was examined. Three agro-industrial materials, such as sunflower seed ...
Enhanced absorption of TiO2 nanotubes by N-doping and CdS quantum dots sensitization: insight into the structure
(Royal Soc Chemistry, Cambridge, 2018)
Anodization of titanium film sputtered on fluorine doped tin oxide (FTO) glass was performed to obtain highly ordered approximate to 2 m long and approximate to 60 nm wide TiO2 nanotubes. The titania films were annealed ...
Composite materials from fully bio-based thermosetting resins and recycled waste poly(ethylene terephthalate)
(Elsevier Sci Ltd, Oxford, 2018)
During the last two decades, interest in bio-based polymers, especially in bio-based composite materials, has grown as a result of environmental concerns. In this paper new composites obtained from fully bio-based unsaturated ...
Functionalization of polypropylene, polyamide and cellulose acetate materials with pyrethrum extract as a natural repellent in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2018)
This study discusses the possibility of supercritical solvent impregnation of polypropylene and polyamide fabrics as well as cellulose acetate in the form of beads and films with pyrethrum extract in order to fabricate ...
The removal of Zn2+, Pb2+, and As(V) ions by lime activated fly ash and valorization of the exhausted adsorbent
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
This study focuses on the use of raw fly ash (FA) and modified fly ash - activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+ and As(V)), followed by the revalorization ...
Selection of the best pollinizer of ‘Celina’ pear
(Int Soc Horticultural Science, Leuven 1, 2018)
The Norwegian newly bred pear cultivar, Celina/QTee®, which was launched in 2010, has been released from the Norwegian breeding program that was initiated in 1983. It was derived from the combination ‘Colorée de Juillet’ ...
