Assessment of surface acidity in mesoporous materials containing aluminum and titanium
(Elsevier Science, 2009-04-01)
The surface acidity of mesoporous molecular sieves of aluminum and titanium was evaluated using four different techniques: n-butylamine volumetry, cyclohexylamine thermodesorption, temperature-programmed desorption of ...
Active potassium niobates and titanoniobates as catalysts for organic sulfide remediation
(Elsevier Science, 2016-02)
Pure (KNbO3) and titanium-substituted (KTi0.1Nb0.9O3 and KTi0.2Nb0.8O3) potassium niobates with perovskite crystalline structures were prepared, characterized and tested as catalysts in the selective oxidation of ...
One step synthesis of high efficiency nickel/mesoporous TiO2 hybrid catalyst for hydrogen evolution reaction
(Elsevier B.V., 2019-02)
Nickel-TiO2 hybrid catalysts are synthesized by electrodeposition and their catalytic activity with respect to the hydrogen evolution reaction is analyzed. Two types of titanium oxide particles, which are commercial particles ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...
Cellular damage mechanism induced by dioxide titanium nanoparticles used in sunscreens
(Universidad Nacional de La Plata, 2020)
Titanium dioxide (TiO 2 ) is widely used in sunscreens because it protects against UVradiation. Current ones are micronized or nanoparticle formulations (TiO 2 @NP), which blendwith the skin tone and attain a better cosmetic ...
Characterization of a mechanochemically activated titanium-hematite mixture: Mössbauer spectroscopy study
(Elsevier Science, 2009-10)
Mechanochemical processes involving reactions between metals and crystalline oxides are of interest because of their potential technological applications in structural, magnetic or electric materials. In addition they can ...
Titanium Dioxide onto Polyethylene for Water Decontamination
(Science & Technology Network Inc, 2009-01)
TiO2 aqueous suspensions under illumination of UV range (310-400 nm UV-A) have demonstrated a big potential for water decontamination and disinfection for human consume. Separation of TiO2 from the process is not easy. ...
