Since its commercial production in the early twentieth century, titanium dioxide (TiO2) has
been widely used as a pigment1 and in sunscreens, 2, 3 paints, 4 ointments, toothpaste, 5 …

Titanium dioxide is the most investigated single-crystalline system in the surface science of
metal oxides, and the literature on rutile (110),(100),(001), and anatase surfaces is …

A large family of two-dimensional transition metal carbides and nitrides (MXenes) has
increasingly raised interest for electronic and optoelectronic applications due to their high …

The present paper gives an overview and review on self-organized TiO2 nanotube layers
and other transition metal oxide tubular structures grown by controlled anodic oxidation of a …

In the recent past a great deal of research efforts were directed toward the development of
miniaturized gas-sensing devices, particularly for toxic gas detection and for pollution …

Titanium dioxide nanotubes, made by anodization, are highly sensitive to hydrogen; for
example, cycling between nitrogen atmosphere and 1000ppm hydrogen a variation in …

A critical review of thin-film semiconducting materials that are used as gas sensors is
presented in this paper. These materials can be approximately divided into two main groups …

This paper reviews the current work carried out on mixed-oxide systems such as SnO2–
WO3, TiO2–WO3 and SnO2–TiO2 with the ultimate aim of the application in gas sensing …

We study the influence of Nb doping on the TiO 2 anatase-to-rutile phase transition, using
combined transmission electron microscopy, Raman spectroscopy, x-ray diffraction and …

Semiconducting oxides are employed as gas-sensitive resistors both for monitoring changes
in oxygen partial pressure and for monitoring small concentrations of impurity gases in air. A …
