A paper in this week's nature Nanotechnology outlines a roadmap for harnessing nanomotors for a broad range of applications, ranging from nanoscale sensing, and transport to assembly. It focuses on two broad classes of nanomotors that burn chemical energy to move along linear tracks: assembly nanomotors and transport nanomotors.
Many of us have been fascinated by the concept of absolute zero, the temperature at which everything comes to a complete stop. But physics tells us otherwise: absolute zero cannot be reached but only approached, and the closer you get, the more interesting phenomena you find!
Scientists at the University of California, Berkeley, have devised a way to squeeze light into tighter spaces than ever thought possible, potentially opening doors to new technology in the fields of optical communications, miniature lasers and optical computers.
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.
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.
Dr. Walt Trybula, director of the Nanomaterials Application Center at Texas State University, will lead off the Friday sessions with a presentation on the impact of nanotechnology in low-cost hive networks.
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.
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.
