The technology centre GAIKER of the Basque Country is working on a project whose aim is to develop intelligent polymers and discover their opportunities. Similarly, it will study the possibilities to introduce those polymers in the existing structures in order to promote their applicability and to create new enterprise initiatives.

GAIKER researches in polymers the elaboration and transformation of intelligent materials. For that aim, it develops its own technologies and then adjust them to

To make super-durable and strong details it is necessary to use so-called diamond composites, i.e. materials (matrixes) with incorporated tiny diamonds. The matrix is to be durable, strong, wear-proof as well as monolithic by structure ensuring chemical interaction with diamonds. To avoid internal tension this matrix must have physical characteristics close to diamond ones. In other case the detail will collapse under load.

Carbide materials fit all these requirements because they are strong

Researchers have discovered how to weld together single-walled carbon nanotubes, pure carbon cylinders with remarkable electronic properties. The discovery could pave the way for controlled fabrication of molecular circuits and nanotube networks.

Pulickel Ajayan, professor of materials science at Rensselaer Polytechnic Institute in Troy, N.Y., and his colleagues in Germany, Mexico, the U.K., and Belgium used irradiation and heat to form the welded junctions.

This is the first time

Accident Leads to Important Discovery

Researchers at Rensselaer Polytechnic Institute in Troy, N.Y., have created large symmetrical crystals that rarely occur in nature. These crystals could be harder than conventional engineering materials. The accidental discovery was made during attempts to make superconducting nanostructures with a simple technique used to create carbon nanotubes.

Researchers say they have developed the world’s strongest, lightest solids. Called aerogels, the sturdy materials are a high-tech amalgam of highly porous glass and plastic that is as light as air.

#In light of the events of Sept. 11 and a heightened interest in homeland security, these new materials show promise as lightweight body armor for soldiers, shielding for armored vehicles, and stronger building materials, the researchers say.

The materials could also be used for better

There may well be a plastic biochip in your future, thanks in part to the National Institute of Standards and Technology (NIST).

Microfluidics devices, also known as “lab-on-a-chip” systems, are miniaturized chemical and biochemical analyzers that one day may be used for quick, inexpensive tests in physicians’ offices. Most microfluidics devices today are made of glass materials. Cheaper, disposable devices could be made of plastics, but their properties are not yet well understood.
