The National Institute of Standards and Technology (NIST) and partners from industry and academia have designed and tested experimental antennas that are highly efficient and yet a fraction of the size of standard antenna systems with comparable properties.
Nanotechnology enables radical material and process improvements, ushering in the next “Industrial Revolution”. Nanotechnology researchers with the University of Colorado at Boulder, report, that for the “first time man can make machines and design processes that are as small and efficient as those we find in living systems.”
Nanomaterials date back before the Romans, with nanoparticle gold tints for glass.
Varying the particle size and shape changes the optical characteristics, allowing gold tints from
red to blue and all colors in between.
A wide range of nanoparticle based products are on the market today. Carbon nanotubes, 100 times stronger than steel at one-sixth the weight, have strengthened Babolat tennis rackets since 2001. We are experiencing the start of a continuous stream of product introductions based on ever more sophisticated nanotechnology application
NIST engineers are working with scientists from the University of Arizona (Tucson) and Boeing Research & Technology (Seattle, Wash.) to design antennas incorporating metamaterials. Metamaterials, are materials engineered with novel, often microscopic, structures to produce unusual properties. The new antennas radiate as much as 95 percent of an input radio signal and yet defy normal design parameters. The experimental antennas are as small as one-fiftieth of a wavelength and could shrink further.
The 4th NIST workshop on single wall carbon nanotubes is being held this week at NIST in Gaithersburg, MD. The workshop features in-depth presentations and discussion of recent breakthroughs in the control and measurement of single-wall carbon nanotube chirality, along with the resulting advances in chirality resolved measurements and applications.
The measurement of carbon nanotube chirality and the use of these measurements to separate the various mixtures will be critical to future applications. The goal of this workshop is to move forward as a community in chirality measurement and to identify and resolve outstanding problems in order to advance applications and to enable well-controlled environmental, health, and safety (EHS) assessments.
