Titanium dioxide, TiO 2, is an important photocatalytic material that exists as two main
polymorphs, anatase and rutile. The presence of either or both of these phases impacts on …

Nanoparticles can be beautiful, as in stained glass windows, or they can be ugly as in wear
and corrosion debris from implants. We estimate that there will be about 70 000 papers in …

The immense potential of colossal permittivity (CP) materials for use in modern
microelectronics as well as for high-energy-density storage applications has propelled much …

1. INTRODUCTION Titania (TiO2) is one of the most chemically stable, environmentally
compatible, and functionally versatile oxide materials. Due to its modified material properties …

Titanium dioxide is one of the most intensely studied oxides due to its interesting
electrochemical and photocatalytic properties and it is widely applied, for example in …

We have investigated the paraelectric-to-ferroelectric phase transition of various sizes of
nanocrystalline barium titanate (BaTiO3) by using temperature-dependent Raman …

High purity, spherical anatase nanocrystals were prepared by a modified sol− gel method.
Mixing of anhydrous TiCl4 with ethanol at about 0° C yielded a yellowish sol that was …

The appearance of colossal permittivity (CP) materials broadens the choice of materials for
energy-storage applications. Here we report colossal permittivity in ceramics of TiO2 co …

The electrical performance of a proton exchange membrane fuel cell is limited by the slow
oxygen reduction reaction (ORR) kinetics. Catalytic improvements for the ORR have been …

Size‐dependent lattice expansion of nanoparticles is observed for many ionic compounds,
including metal oxides, while lattice contraction prevails for pure metals. However, the …
