The future of manufacturing: Nanotechnology

Babak Parviz of University of Washington, named by Technology Review as one of this year’s outstanding innovators under the age of 35, writes in the Sept/Oct issue (free reg req’d) about self-assembly: In nature, components “self-assemble” to yield complex functional systems. Inspired in part by this observation, a number of research groups are working to… Continue reading The future of manufacturing: Nanotechnology

Nanotechnology: Enough with the wet/dry debate already

Nanowerk brings to our attention some confusion on an IEEE blog: Somewhere along the line, the advocates for molecular nanotechnology (MNT) seem to have lost interest in actually seeing molecular manufacturing come to pass if it meant that the concepts of the mechanically engineered approach (Dry) are abandoned in favor of a biologically engineered method… Continue reading Nanotechnology: Enough with the wet/dry debate already

Nanotechnology classic Engines of Creation new edition

Celebrating its 20th anniversary, the nanotechnology classic book Engines of Creation is out in a new, free e-book version (5.4 MB pdf) from WOWIO. Material added since the original edition includes a Letter from the Author, Feynman’s 1959 talk, Advice to Aspiring Nanotechnologists (very similar to the author’s Foresight Briefing 1: Studying Nanotechnology, a longtime… Continue reading Nanotechnology classic Engines of Creation new edition

Brits take lead toward advanced nanotechnology

Earlier we expressed enthusiasm for the UK Software Control of Matter project, and sure enough, they have already made progress toward setting themselves an ambitious, visionary goal which is expected to be funded: We propose to create a molecular machine that will build new materials under software control. The output of the machine will be… Continue reading Brits take lead toward advanced nanotechnology

Nanotechnology torque detected with exquisite sensitivity

The useful website Nanowerk describes a new technique invented by researchers in Spain which should be useful in analyzing nanotechnology devices: Many protein molecules, such as those that process DNA, execute twisting motions, but researchers have only managed to measure the torques in a few cases. Often the random thermal jiggling of water molecules makes… Continue reading Nanotechnology torque detected with exquisite sensitivity

UK pulling ahead on nanotechnology matter compiler

The idea of a nanotech-based matter compiler began in the U.S., and we do some relevant computer modeling studies, but the U.K is pulling ahead toward actually building one. Twenty to thirty lucky researchers will gather on January 8-12, 2007, to brainstorm how to do this, after which the U.K. government will spend about US$… Continue reading UK pulling ahead on nanotechnology matter compiler

Nanotechnology desktop factories timing debated

I remember when the most popular timing estimate for molecular manufacturing was “huh?” Next it was “never”. Then “centuries”. Here’s where we are today, as reported by the Australian Broadcasting Corp.: Dr Peter Binks of Nanotechnology Victoria, a sponsor for Treder’s tour, says his organisation does not “yet buy into the idea” of the desktop… Continue reading Nanotechnology desktop factories timing debated

Yet another nanotech journal: Small from Wiley

Check out the new journal Small from Wiley Interscience, publisher of the book Nanosystems. Sample article from the first issue: "Powering a Supramolecular Machine with a Photoactive Molecular Triad" and from issue 3: "DNA Nanodevices". Most articles are on nanostructures which are not atomically precise, such as from issue 5: "Halloysite Nanotubes as Biomimetic Nanoreactors". (OK, maybe that last title is a bit jargony…) A problem: many articles have no free abstract.

Proteins controlled by mechanical spring at UCLA

UCLA physicist Giovanni Zocchi, a member of the California NanoSystems Institute, explains: "We have made an artificial mechanism of allosteric control based on mechanical tension…We insert a molecular spring on the protein…By gluing together two disparate pieces of the cell's molecular machinery, a protein and a piece of DNA, we have created a spring-loaded protein which can be turned on and off."

Physicist suggests nanotech to deal with heat death of universe

String theorist Michio Kaku suggests molecular nanotechnology as one way to deal with the heat death of the universe: "There is nothing in the rules of science to prevent the regeneration of an advanced civilisation from the molecular level. For a dying civilisation trapped in a freezing universe, this may be the last hope." The size of his proposed devices seems to vary, however. Read more for the full quote.
