Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Ceramics International, 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Ceramics International, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Ceramics International, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
Influence of femtosecond pulsed laser irradiation on bismuth germanium oxide single crystal properties
(Materials Research Bulletin, 2016)
High quality bismuth germanium oxide single crystals were irradiated by a femtosecond pulsed laser beam of increasing power. Analyses performed on irradiated and unirradiated samples showed significant changes in transmittance, ...
Photocatalytic degradation of alprazolam in water suspension of brookite type TiO2 nanopowders prepared using hydrothermal route
(Elsevier, 2015)
Two series of nanocrystalline brookite-type powders have been synthesized by using combined sal gel hydrothermal method with titanium tetrachloride (TiCI4) as a precursor and hydrothermal temperature and reaction time ...
Photoluminescence of europium(III)-doped (YxSc1-x)(2)O-3 nanoparticles: Linear relationship between structural and emission properties
(Elsevier, 2016)
Europium (III)-doped (YxSc1-x)(2)O-3 nanocrystalline powders of different compositions (x=0, 0.25, 0.5, 0.75 and 1) are synthesized using a polymer complex solution method. Comparative structural and optical characterization ...
WO3/TiO2 composite coatings: Structural, optical and photocatalytic properties
(Materials Research Bulletin, 2016)
WO3/TiO2 and TiO2 coatings were prepared on titania substrates using facile and cost-effective plasma electrolytic oxidation process. The coatings were characterized by X-ray diffraction, scanning electron microscopy, ...
Preparation of Y2O3:Eu3+ nanopowders via polymer complex solution method and luminescence properties of the sintered ceramics
(Ceramics International, 2011)
Herein we presented polymer complex solution method for production of well crystalline europium doped Y2O3 nanopowders. Polyethylene glycol (PEG) of five different molecular weights is used both as a fuel and as a nucleation ...
Changes of properties of cured and uncured disiloxane bisbenzocyclobutene thin films under irradiation
(Progress in Organic Coatings, 2013)
The effects induced by alpha-particles and laser beam irradiation in air atmosphere in uncured and cured bisbenzocyclobutene (BCB) 2 mu m thick films, spin-coated on glass/ITO surface have been investigated. alpha-Particle ...
Ultrasonic spray pyrolysis of surface modified TiO2 nanoparticles with dopamine
(Materials Chemistry and Physics, 2013)
Spherical, submicronic TiO2 powder particles were prepared in the low temperature process of ultrasonic spray pyrolysis (150 degrees C) by using as a precursor aqueous colloidal solutions consisting of surface modified 45 ...
