General description

Anatase titanium(IV) oxide, also known as titanium dioxide or titania, is a white crystalline powder that is widely used in a variety of applications. Anatase is one of the three naturally occurring crystalline phases of titanium dioxide, the other two being rutile and brookite. Among these three phases, anatase is the most reactive and tends to have the highest surface area, which makes it useful in applications where high reactivity and surface area are desirable.

Application

Phase-pure anatase is employed in the solid state synthesis of the mixed oxide NaTiO2 which has been considered as a possible antiferromagnetic material.

Tissue simulating phantoms can provide a valuable platform for quantitative evaluation of the performance of diffuse optical devices. While solid phantoms have been developed for applications related to characterizing exogenous fluorescence and intrinsic chromophores such as hemoglobin and melanin, we

During the development and early testing phases of new photoacoustic (PA) breast imaging systems, several choices need to be made in aspects of system design and measurement sequences. Decision-making can be complex for state-of-the-art systems such as 3D hybrid photoacoustic-ultrasound

Articles

In this paper, we discuss recent advances in the preparation of various TiO2 porous structures via hard and soft-templating routes. Specifically, we focus on recent developments in TiO2 mesoporous thin films in a combined sol-gel and evaporation-induced self-assembly (EISA) process.

Thermoelectric Performance of Perovskite-type Oxide Materials

Electronically, it behaves as a wide band gap (3.2 eV) semiconductor and exhibits memristor properties.2 Optically, TiO2 has high opacity with a very high refractive index3 (>2.4), and it exhibits strong absorbance in the UV range.

The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
