- Clay-filled 'nanocomposites' offer
extraordinary properties.
They are generating a lot of excitement despite the secrecy surrounding their development. They are said to exhibit dramatic improvements in mechanical, thermal, barrier, and flame-retardant properties, all without significant loss of toughness or clarity. These new reinforced plastics, known as nanocomposites, contain very tiny platelets of a special type ......
- Nanocomposites: a little goes a long
way.
From auto parts to barrier packaging, the race is on to commercialize nano-clay thermoplastic composites. Just a pinch of these infinitesimally small particles can dramatically raise mechanical, thermal, barrier, and flame-retardant properties. Why all the excitement about the new class of mineral-reinforced plastics known as nanocomposites? Because relatively small amounts ......
- Nanoscale technology yields better thermal insulators
Researchers at the University of Illinois at Urbana-Champaign created a better thermal insulator by controlling material structure at the nanoscale. Says David Cahill, a professor of materials science and engineering, "Making nanolaminates of dissimilar materials let us significantly cut thermal conductivity because heat cannot pass efficiently across the material interfaces." ......

- MEASURING THE TINIEST STRUCTURES.
Researchers at the Georgia Institute of Technology in Atlanta have developed a technique to measure the comparative bending strength of individual carbon nanotubes produced by two competing processes. The technique characterizes nanotubes produced by traditional high-temperature carbon arc discharge and nanotubes grown at a lower temperature by catalyst-assisted pyrolysis. Until ......
- Superhot nanotubes gain strength as they stretch
Researchers at Lawrence Livermore National Laboratory, Boston College, and the Massachusetts Institute of Technology have devised a high-temperature (3,600?F) strengthening technique that boosts the strength of single-walled carbon nanotubes by a factor of nearly 2.8. The super-strain can be used to tune electronic properties of the carbon nanotubes for applications ......
