New material could mean easier manufacture of paper-thin TVs and “smart” cloth

Researchers have developed a new plastic that conducts electricity, may be simpler to manufacture than industry counterparts and easily accommodates chemical attachments to create new materials.

Developed by TDA Research in Wheat Ridge, Colo., Oligotron polymers are made of tiny bits of material that possess a conducting center and two, non-conducting end pieces. The end pieces allow the plasti

A new generation of materials inspired by the ancient Greeks have been developed by scientists for use in miniaturised devices. The materials are robust, flexible films with perforations on the nano scale and have nano coatings. They are environmentally safe and will enable ultra-fast optoelectronic communication. They are produced by the self-assembly of an intricate

Food packs, containers, toothpaste tubes, wheels, glue, paints … they are all made of polymers. The world of polymers is infinite and, so, there is a great variety. The majority have been designed for a specific application; given that at times the application might be for a food container and, at others, for the superstructure of a vehicle. The specifications needed in either case are quite different.

Polymers are gigantic molecules, but they are synthesised from small compounds: monomer

We’ve all sat there in a dull moment at work stretching an elastic band between our fingers and watching it return to its original shape and size as we let it go. But how many of us would have thought of combining the elasticity of rubber with the optical properties of the liquid crystals commonly used in watches, laptops and calculators? On Monday 5th April at the Institute of Physics Condensed Matter and Materials Physics Conference in Warwick, Professor Mark Warner from the University of Camb

It looks like glass and feels like solidified smoke, but the most interesting features of the new silica aerogels made by UC Davis and Lawrence Livermore National Laboratory researchers are too small to see or feel. Lighter than styrofoam, this strange material is riddled with pores just nanometers in size, leaving it 98 percent empty.

Water can soak into the material, but in the confined space the water molecules arrange themselves in unusual ways, said Subhash Risbud, professor of chemica

A stable cluster of aluminum atoms, Al13, acts as a single entity in chemical reactions, demonstrating properties similar to those of a halogen, reports a research team led by A. Welford Castleman Jr., the Evan Pugh Professor of Chemistry and Physics and the Eberly Family Distinguished Chair in Science at Penn State, in a paper to be published in the 2 April 2004 issue of the journal Science. Experimental results and theoretical calculations indicate that the cluster chemically resembles a “superhalo
