Titanium Oxide Nanotubes

Nano Tubes

Nanotubes are structures of super molecular crystals, in the form of hollow cylinders. Today the best known are the nano tube carbons, whose walls are constructed of rolled graphene (monatomic layer of graphite). But there are also inorganic nano tubes and nano tubes formed from the DNA.

Titanium Nano Tubes Potential for Solar Panels

The new approach is to develop them with light-sensitive pigments, which have already been manufactured using nano particles and various pigments (Kijima, pp. 223-236). Researchers are studying titanium nano tubes to replace the layers of pigment particles in the sensitive solar cells, and their initial effort produced about a 3 percent conversion of solar energy into electricity. The inability of researchers to grow longer nano tubes of titanium, than the proportion of solar conversion is a big concern.

Researchers believe that we can achieve a ratio of 15 percent conversion with these cells. This 15 percent will be achieved through a manufacturing system fairly easy and commercially viable. This series of nano tubes is then coated with a commercially available pigment. The pigment constitutes nano tubes with the negative and positive electrode that seals the cell containing an electrolyte iodinated. When sunlight passes through the glass, the energy incident on the molecules of the pigment and an electron is released. If electrons find their way out of the tube towards the negative electrode, the current starts flowing. Many electrons are not and are recombined, but the structure of titanium dioxide tubes allows the amount of electrons flowing is an order of magnitude larger than the particle layers (Marcus, pp. 423-460).

The thickness of the titanium layer prevents obtaining greater height of the nano tubes. The tubes have longer and thicker coatings. It makes the current pass through strongly and produce more electrons, producing more electricity (Missert, pp. 85-94) .

Conventional solar cells are made of monolithic blocks of silica glass, manufactured slowly, which is sliced into wafers. Grimes worked on this issue and produced an easier approach; covering a piece of glass with tin oxide doped with fluorine, and then projecting a layer of titanium. Currently, researchers can extend a titanium layer of 500 nanometers thick, and then anodized to be placed in an acid bath with a mild electric current (Jackson, Hargreaves, pp. 200-245).

Nano Tubes against Cancer?

Nanonurki is very small, super strong, thin tubes that conduct electricity and heat. The advantages of nano tubes are often used in nano technology, which is everywhere. Typically, the nano tube is considered a molecule with a length to diameter ratio greater than 1 million. Mostly this term is understood only carbon nano tubes, but there are more kinds of them.

A spectacular example is the possibility of their use in studies of the brain, and the more mundane but no less striking (taking into consideration the size of modern TV sets) in the construction of flat panel displays and LEDs. Recently it was found that nano tubes can be combined. This is the idea of some of the fantasy ...
