Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Ltd, 2019)
The ∼60 nm wide and ∼2 μm long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect of pre- and post-annealing ...
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 ...
Nimonic 263 microstructure and surface characterization after laser shock peening
(Croatian Metallurgical Soc, Zagreb, 2015)
The Laser Shock Peening (LSP) is applied to the surface of Nimonic 263 alloy. The changes in microstructure and surface topography are observed and analyzed by Scanning Electron Microscopy (SEM), profilometer and microhardness ...
Sorption of textile dyes from textile wastewater by chitosan-based hydrogel / Sorpcija boja za tekstil iz tekstilnih otpadnih voda pomoću hidrogela na bazi hitozana
(Savez inženjera i tehničara Srbije, Beograd, 2018)
With the excessive risks that are present in today's environment, it is of great importance to treat wastewaters before their discharge in water streams. One of the everyday challenges is design of a low-cost and environmentally ...
Wastes from bioethanol and beer productions as substrates for L(+) lactic acid production - A comparative
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Waste substrates from bioethanol and beer productions are cheap, abundant and renewable substrates for biorefinery production of lactic acid (LA) and variability in their chemical composition presents a challenge in their ...
Multiscale characterization of antimicrobial poly(vinyl butyral)/titania nanofibrous composites
(Wiley, Hoboken, 2017)
Titania nanofillers were used to reinforce nanofibers in composite mats produced by electrospinning of poly(vinyl butyral) with two different concentrations of polymers. The titania nanoparticles and titania nanotubes were ...
Modification of natural clinoptilolite and ZSM-5 with different oxides and a study of the obtained products in lignin pyrolysis
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, different metal oxides (MO) supported on two types of zeolites: 1) natural clinoptilolite (NZ) and 2) synthetic zeolite, ZSM-5 were prepared and tested as catalysts in the fast pyrolysis of hardwood lignin. ...
Characterization of scaffolds based on chitosan and collagen with glycosaminoglycans and sodium alginate addition
(Elsevier Sci Ltd, Oxford, 2018)
Scaffolds based on chitosan (CTS), collagen (Coll), and glycosaminoglycans (GAGs) cross-linked by sodium alginate (SA) were obtained with the use of the freeze-drying method. They were characterized by different analyses, ...
The effect of graphene loading on mechanical, thermal and biological properties of poly(vinyl alcohol)/graphene nanocomposites
(Elsevier Science Inc, New York, 2016)
Poly(vinyl alcohol)/graphene (PVA/Gr) nanocomposite was synthesized with the aim of developing a novel improved material. The PVA/Gr nanocomposite was characterized by UV-visible spectroscopy, cyclic voltammetry, Raman ...
