Another advantage of mixed crystal nano titania is its improved mechanical strength and durability. When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environments When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environments When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environments When combined with other materials, such as metals or polymers, the resulting composite exhibits superior resistance to wear and tear, making it suitable for use in harsh environmentsmixed crystal nano titania. This property also extends to its thermal stability, allowing it to maintain its structural integrity at high temperatures without undergoing phase transitions or degradation.

Titanium dioxide, (TiO2), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity.

The gastrointestinal tract is a complex barrier/exchange system, and is the most important route by which macromolecules can enter the body. The main absorption takes place through villi and microvilli of the epithelium of the small and large intestines, which have an overall surface of about 200 m2. Already in 1922, it was recognized by Kumagai, that particles can translocate from the lumen of the intestinal tract via aggregation of intestinal lymphatic tissue (Peyer’s patch, containing M-cells (phagocytic enterocytes)). Uptake can also occur via the normal intestinal enterocytes. Solid particles, once in the sub-mucosal tissue, are able to enter both the lymphatic and blood circulation.
