My dentist Dr.Raj Kamal, recounted how most of the books and materials that he had learnt and used in college are now obsolete. New tools, materials and products have changed the face of dentistry today.

For instance, dentists today use alloys of Titanium and Cobalt instead of steel or iron for dental implants.

Pure Cobalt is not found in nature but its compounds are found in rocks, minerals, plants and animals. Cobalt is a silvery metal with properties similar to iron and nickel. But unlike steel, cobalt is more flexible and is therefore easier to handle in the in-house labs of practicing dental surgeons.

Cobalt is used with other metals to make metal alloys. Cobalt alloys have several industry applications. It is used in making pigments and drying agents in paints, printing inks, pottery glaze, and orthopedic and dental implants, dental prosthesis.

Truely, dental industry has come a long way. i remember how scared we used to be when we had to visit the family dentist, but today’s youngsters want all kinds of fancy things in their mouth. Just as I was about to leave Dr. raj Kamal showed me  Swaroski crystals in pink and blue that are in great demand by youngsters who like to show off their twinkling teeth! Gold teeth are so passe indeed!

And on a different note,

It is not just in dentistry that gold is replaced by new alloys. Of late, even gold wedding bands are replaced by Cobalt and Tungsten.

Now, could it be one of the reasons why weddings are not holding fast as long as they used to earlier?

RUSNANO CEO Anatoly Chubais and the vice chairman of investment company SUN Group, Shiv Vekram Khemka, signed a memorandum of understanding for collaboration in nanotechnology. The document was signed on the opening day of Aero India 2011, the eighth international exhibition on aerospace, defense, and civil aviation. The event, which takes place in Bangalore, is “Asia’s premier air show.”



The memorandum states that RUSNANO and SUN Group will carry out joint analyses of nanotechnology applications in sectors of the economy where business prospects are most promising and that they will support the use of existing and yet-to-be developed nanotechnology products. The parties intend to promote broadening cooperation between Russian and Indian companies engaged in the global technology chain. SUN Group will assist RUSNANO’s project companies to identify partners in India with whom joint ventures can be established.

Trade between Russia and India has doubled during the past five years. The RUSNANO—SUN Group accord will contribute to further growth through partnerships in high technology.

About RUSNANO The Russian Corporation of Nanotechnologies (RUSNANO) was established in 2007 by the Federal law ¹ 139-FZ to enable Government policy in the field of Nanotechnology.

To accomplish this task, RUSNANO co-invests in nanotechnology industry projects that have high commercial potential or social benefit. Early-stage investment by RUSNANO lowers the risk of its investment partners from the private sector.

RUSNANO participates in building nanotechnology infrastructure, which includes the nanotechnology centers of excellence, business incubators and early stage investment funds. RUSNANO provides scientific and educational programs that are required for its investment projects to succeed, and also supports the popularization of nanoscience and nanotechnology. RUSNANO selects promising spheres for investment based on longer-term sight created by the leading Russian and world experts.

To assist the Russian nanotechnology industry advance to the global market and strengthening of its international links RUSNANO develops partnerships with the leading nanotechnology centers in the world and organizes the annual Nanotechnology International Forum in Russia.
