larens imanyuel writes "In each phase of the Industrial Revolution a new industrial system has arisen on top of the previous one. Each has involved enabling technology, new organizational principles, and new major product lines. For instance, a century ago electrification with small motors allowed Henry Ford to design the modern assembly line to mass produce automobiles. Several decades ago silicon technology allowed the mass production of personal computers through an exponential refinement of technique, commonly known as Moore's law, that became the Semiconductor Roadmap. The question naturally arises as what the equivalent industrial system will be for the next half century."

The International Journal of Engineering Education has published a Special issue on Nanotechnologies (Volume 18 number 5, September 2002). The Table of Contents is available on the Web. Michael Wald, Editor, writes that single copies are available at US$35+US$15 postage. Inquire at [email protected].

Gina Miller writes "An article summarizing progress with carbon nanotube field effect transistors is available on the nanotechweb.org web site. Nanotubes speed up, by Adrian Bachtold, which originally appeared in the August issue of Physics World, reports that 'Transistors fabricated from carbon nanotubes now have electrical characteristics that can rival silicon devices.'"

Gina Miller writes "A Purdue University press release 'Nanoantennas' could bring sensitive detectors, optical circuits describes mathematical simulations published by Purdue researchers that demonstrate that antennas made from metal wires and spheres only about 10 nm wide should be able to bend light in the opposite direction to the usual case to produce a 'super lens' that 'drastically improves the quality of medical diagnostic images.'"

Zarathustra2101 writes "The current issue of Reason magazine features an article entitled Forever Young: The New Scientific Search for Immortality by Ronald Bailey. The author paraphrases Dylan Thomas thus: 'The defining political conflict of the 21st century will be the battle over life and death. On one side stand the partisans of mortality, who counsel humanity to quietly accept our morbid fate and go gentle into that good night. On the other is the party of life, who rage against the dying of the light and yearn to extend the enjoyment of healthy life to as many as possible for as long as possible.'"

Three Nanodot readers wrote (see below) about The New York Times piece Opposition to Nanotechnology by Barnaby J. Feder, August 19, 2002, which reports that "nanotechnology is encountering the kind of real-world headwinds that have impeded biotechnology." The central focus of the article is the concerns of the ETC Group about nanoparticles in the environment penetrating living cells and accumulating in animal organs (see "Call for moratorium on commercial nanomaterials," Nanodot July 29, 2002).

JohnFaith writes "The University of Washington Center for Nanotechnology will be holding a three day workshop called "Nanotech meets Business" September 18-20, 2002. Registration deadline is Sept. 10, but costs less if you sign up before the 5th." Non-technical presentations on the 18th followed by more technical workshop Sept. 19-20.

An article in The Arizona Republic of Aug. 06, 2002 Molecule-size machines the wave of the future, ASU scientists say reports that researchers at Arizona State University "think the body's billions of tiny machines are a key to a new field that has excited scientists, government officials and investors around the world."

from the jolted-atoms dept.
waynerad writes "Researchers at the Georgia Institute of Technology have created what may be the world's smallest electroluminescent light source using photon emissions from individual molecules of silver".

… the work could lead to new types of nanometer-scale optical interconnects, high-resolution optical microscopy, nanometer-scale lithography and other applications that require very small light sources. And because single molecules are known to emit one photon at a time, the technique could ultimately be the basis for high-efficiency quantum information processing and cryptography.

Carrie Bonforte writes to point to a Business 2.0 article Starting Small, by Erick Schonfeld, August 09, 2002, about "A Bay Area company called Nanomix … trying to make industrial devices out of a material that's just a single atom thick." The article reports that Nanomix's work with carbon nanotubes is focused on two specific markets: chemical gas sensors, and hydrogen-storage systems.
