Mechanochemical Reactions in Fe2O3–M (M: Al, Ti)
(Springer, 2001-04)
The production of metal–ceramic nanodispersion by mechanical milling of powders through the displacement reaction Fe2O3+M→Fe+M-oxide (with M: Al, Ti) was studied. The reaction progress with milling time was followed by ...
Photocatalyzed degradation of flumequine by doped TiO2 and simulated solar light
(Elsevier Science, 2008-06)
Titanium dioxide was obtained in its pure form (TiO2) and in the presence of urea (u-TiO2) and thiourea (t-TiO2) using the sol-gel technique. The obtained powders were characterized by BET surface area analysis, Infrared ...
Synthesis, characterization and photocatalytic activity of 1D TiO2 nanostructures
(IWA Publishing, 2014-01)
Nanowire/nanorod TiO2 structures of approximately 8 nm in diameter and around 1,000 nm long were synthesized by alkaline hydrothermal treatment of two different TiO2 nanopowders. The first precursor was TiO2 obtained by ...
DFT study of Ni segregation at the B2-NiTi(110)/rutile-TiO2(110) interface
(Elsevier Science, 2019-09-30)
NiTi alloy has important properties such as shape-memory, super-plasticity, resistance, and biocompatibility, therefore is frequently used in biomedical devices. We studied the oxidized form of this alloy and possible Ni ...
Exploring the properties of Ag5-TiO2 interfaces: Stable surface polaron formation, UV-Vis optical response, and CO2 photoactivation
(Royal Society of Chemistry, 2020-03-04)
Using a combination of first-principles modelling, X-ray absorption spectroscopy, and diffuse reflectance spectroscopy measurements, we explore the properties of Ag5-modified TiO2 surfaces. A general electron polarization ...

Low (and negative) thermal expansion Al2TiO5 materials and Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4 composite materials. Processing, initial zircon proportion effect, and properties
(Elsevier, 2018-12)
Aluminum titanate (Al2TiO5) materials and aluminum titanate - mullite- zirconium titanate (Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4) composite materials were successfully processed from fine commercial powders and characterized. ...
Reactive dyes remotion by porous TiO2-chitosan materials
(Elsevier Science, 2008-04)
In this work, the aim was to evaluate the remotion (adsorption plus degradation) of two reactive dyes, Methylene Blue (MB) and Benzopurpurin (BP), from aqueous solutions by the utilization of TiO2-chitosan microporous ...
Role of rare earth elements and entropy on the anatase-to-rutile phase transformation of TiO2thin films deposited by ion beam sputtering
(American Chemical Society, 2020-11)
The role played by oxygen vacancies and rare earth (RE) elements in the anatase-to-rutile (A−R) phase transformation of titanium dioxide (TiO2) is still a matter of controversy. Here, we report the A−R transformation of ...
