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 ...
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 ...
A possible connection between phosphate tungsten bronzes properties and briggs-rauscher oscillatory reaction response
(Science of Sintering, 2021)
The calcium phosphate tungsten bronze (Ca-PWB) has been synthesized and characterized (TGA, DSC, XRPD, FTIR, SEM). The influence of solid insoluble materials Ca-PWB, as well as lithium doped (Li-PWB) and cation free phosphate ...
Electrochemical and structural properties of Ni(II)-alumina composites as an annealing temperature function
(Science of Sintering, 2019)
Alumina powders, pure and doped with nickel, were synthetized by sol-gel method and calcined at 500, 900 and 1100oC in order to obtain mesoporous structures with a high specific surface area, well adapTab. to catalytic ...
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 ...
The influence of alumino-silicate matrix composition on surface hydrophobic properties
(Science of Sintering, 2019)
The purpose of this investigation is to investigate the hydrophobicity of geopolymers, new alumino-silicate materials and the influence of Si/Al ratio on their surface properties. Contact angle measurement (CAM) as reliable ...
Macroporous monoliths based оn natural mineral sources, clay аnd diatomite
(Science of Sintering, 2020)
Macroporous silica ceramic was obtained using clay and diatomite. Boric acid as a low-cost additive in the amount of 1 wt% was used. These porous materials were obtained at low forming pressure (40-80 MPa) and lower sintering ...
