Bacterial cellulose–SiO 2 @TiO 2 organic–inorganic hybrid membranes with self-cleaning properties
(2019-01-15)
Abstract: This work reports the preparation of bacterial cellulose (BC) membranes with self-cleaning properties. SiO 2 @TiO 2 (anatase) spherical nanocomposites (around 50 nm in diameter) were prepared by sol–gel process ...
Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation: photocatalytic reduction of Cr(VI)
(Elsevier Science Sa, 2017-04)
Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200-3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ...

Incorporation of silver nanoparticles on Ti7.5Mo alloy surface containing TiO2 nanotubes arrays for promoting antibacterial coating – In vitro and in vivo study
(2018-10-15)
Bulk and surface properties are very important for materials used in biomedical applications. The development of new surface treatments, such as antibacterial coatings can directly affect the response of the surface. The ...
Simple TiO 2 Coatings by Sol–Gel Techniques Combined with Commercial TiO 2 Particles for Use in Heterogeneous Photocatalysis
(American Scientific Publishers, 2017-07)
TiO2 coatings were obtained by a combination of a sol?gel process with the addition of commercial TiO2 particles (Degussa-Evonik P25). Simple and composite (with P25) sols were deposited by dip-coating on glass plates ...
Fabrication of TiO2 Crystalline Coatings by Combining Ti-6Al-4V Anodic Oxidation and Heat Treatments
(Hindawi Publishing Corporation, 2015-01)
The bio- and hemocompatibility of titanium alloys are due to the formation of a TiO2 layer. This natural oxide may have fissures which are detrimental to its properties. Anodic oxidation is used to obtain thicker films. ...
