Scientists determine strength of 'liquid smoke'

Aerogel, also known as liquid smoke or 'San Francisco fog', is an open-cell polymer with pores smaller than 50 nanometers in diameter. For the first time, Lawrence Livermore and Lawrence Berkeley scientists have peered into this material and created three-dimensional images to determine its strength and potential new applications.

New disease-fighting nanoparticles look like miniature pastries

Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques.

OECD issues final report for nanotechnology standards workshop

The International Workshop on Documentary Standards for Measurement and Characterisation in Nanotechnologies was held February 26-28, 2008 at the National Institute of Standards and Technology, Gaithersburg (USA), in co-ordination with ISO, IEC, NIST and the OECD. The participants discussed the development, efficacy, harmonisation and uptake of documentary standards broadly relevant to the field of measurement and characterisation for nanotechnologies.

'Nanoblades' simplify assembly of magnets used in many advanced weapon systems

Ultra-strong, high-temperature, high-performance permanent magnet compounds, such as Samarium Cobalt, are the mainstay materials for several industries that rely on high-performance motor and power generation applications, including the Department of Defense (DOD) and the automotive industry. Until now, producing Samarium Cobalt has been a difficult and expensive multi-step process. Northeastern University researchers have broken new ground with an innovative invention of a rapid, high-volume and cost-effective one-step method for producing pure Samarium Cobalt rare earth permanent magnet materials.

Golden scales

Using the same technology with which they created the world's first fully functional nanotube radio, researchers with Berkeley Lab and the University of California (UC) at Berkeley have fashioned a nanoelectromechanical system (NEMS) that can function as a scale sensitive enough to measure the mass of a single atom of gold.

Scaling down to diamond quantum electronics

La Trobe physicist Chris Pakes is aiming to scale the technology down further into the realm of quantum physics. He and co-researchers are talking about one-dimensional nano-wires and individual atoms performing the tasks of transistors, not using silicon, but diamond.
