Effect of Eu3+ - dopant concentration on structural and luminescence properties of SrY2O4 nanocrystalline phosphor and potential application in dye-sensitized solar cells
(Science of Sintering, 2018)
SrY2O4 phosphors were doped with different concentrations of Eu3+ (0.5, 1, 2, 4, 8 and 10 at %) in order to investigate the maximal doping concentration of Eu3+ and its implementation in solar cell devices. Samples were ...
Structural, morphological and electrical properties of multi-doped calcium phosphate materials as solid electrolytes for intermediate temperature solid oxide fuel cells
(Science of Sintering, 2018)
Modified solution precipitation method was used to prepare pure and doped Mg, Sr and Na hydroxyapatite type materials (CaP, CaMgP and CaSrNaP). Modification consisted of partial substitution of nitrates by acetate solution ...
Structure and photocatalytic properties of sintered TiO2 nanotube arrays
(Science of Sintering, 2018)
One-dimensional (1D) TiO2 nanotubes perpendicular to the substrate were obtained by electrochemical oxidation of titanium foil in an acid electrolyte. In order to alter the crystallinity and the morphology of films the ...
Use of sintering to immobilize toxic metals present in galvanic sludge into a stabile glass-ceramic structure
(Science of Sintering, 2018)
Galvanization process requires the use a large amount of water and produces wastewaters that are usually purified by conventional cost-effective procedure. This kind of treatment generates waste sludge which becomes a ...
Influence of temperature and different hydroxides on properties of activated carbon prepared from saccharose. Characterization, thermal degradation kinetic and dyes removal from water solutions
(Science of Sintering, 2018)
In presented paper, influence of temperature, precursor concentration and different hydroxides on properties of activated carbon obtained from saccharose were investigated. The samples were prepared by hydrothermal treatment ...
Electrospun alumina fibers doped with ferric and magnesium oxides
(Science of Sintering, 2018)
It is well known that alumina possesses good mechanical and chemical properties. Nanofibers having alpha - alumina structure was used as reinforcement for metal, polymer and ceramic matrix composites. In this study, three ...
Alumina particles doped with ferric as efficient adsorbent for removal of Reactive Orange 16 from aqueous solutions
(Science of Sintering, 2018)
Ferric oxide doped alumina particles were prepared via the sol-gel method and their performance as Reactive Orange 16 adsorbent was evaluated. The concentrations of the Reactive Orange 16 were monitored using a UV-Vis ...
Structural, morphological and electrical properties of alumina/YAG composites as solid electrolyte for IT - SOFC
(Science of Sintering, 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 ...
Influence of synthesis conditions on morphological features of the SBA-15 containing only elongated and rounded/spherical grains
(Science of Sintering, 2018)
Mesoporous silica SBA-15 materials of high specific surface area (similar to 700 m(2) g(-1)) were synthesized by using block copolymer Pluronic P123 as template and tetraethoxysilane as silica source. The obtained materials ...
