Foresight Nanotech Institute Weekly News Digest: February 27, 2008
Digest news items also appear as posts on our blog Nanodot at http://foresight.org/nanodot. Each news item can be discussed individually in the comments area on Nanodot. We invite your participation!
An interview by Nanotechnology.com of the director of the Center for Nanoscale Chemical-Electrical-Mechanical Manufacturing Systems got our attention. I'd give you a URL for this interview but it doesn't seem to be on the web, only in email. An excerpt…
After several months of public consultation, the European Commission has announced a Code of Conduct for Responsible Nanosciences and Nanotechnologies Research…
Fibers made from zinc oxide nanowires can generate electrical current from low frequency mechanical motion, like body movements. Last April we noted the initial success of Prof. Z.L. Wang at Georgia Tech in using nanowires to produce electricity … Now PhysOrg.com reports Prof. Wang's further progress with nanotech power systems…
Among the most useful tools for nanotechnology are various scanning probe tips for surface modification. A few years ago, the IBM Millipede project demonstrated the use of an array of silicon cantilevers as a nanotech memory device … In Technology Review, Kevin Bullis describes another approach to computer memory based upon similar arrays of atomic force probe tips…
The development of nanotechnology for atomically precise manufacturing would benefit from the ability to attach specific chemical binding sites to scanning probe microscope tips. Carbon nanotubes offer several advantages as very sharp probes for nanotech tools. Writing at nanotechweb.org (requires free registration), Belle Dumé reports that Japanese scientists have succeeded in chemically attaching proteins specifically to the tips of multiwalled carbon nanotubes…
Fundamental advance in understanding RNA folding may advance use of RNA building blocks for nanotechnology
Stanford University scientists have achieved new, detailed understanding of how a polymer folds into a unique three-dimensional structure by using an "optical trap" to precisely unfold a functional RNA molecule… Progress in understanding the complex folding patterns of functional RNA molecules may facilitate building molecule machinery from RNA…
Do you believe that nanotechnology will give society the ability to tackle the hard challenges facing humanity? What's your priority for nanotechnology: cancer treatments and longevity therapies, sustainable energy, clean water, a restored environment, space development, or "zero waste" manufacturing? Or perhaps there are potential nanotech scenarios you would like to prevent.
If you would like to help influence the direction of this powerful technology, please consider becoming a member of Foresight Nanotech Institute. With your support, Foresight will continue to educate the general public on beneficial nanotechnology and what it will mean to our society.
NanoManufacturing Conference & Exhibits
Looking to understand what nanotechnology means for you? Need to understand how and why nanotechnology can improve your products, process, and may even cut costs? Interested in learning about the latest applications and trends in top-down fabrication and bottom-up assembly techniques? Then this event is for you!
This conference will highlight the current, near-term, and future applications of nanotechnology and how they are transforming the way we manufacture products. Peer networking, information sharing, and technology exchange among the world's nanomanufacturing leaders will be a key feature of the event.
Foresight members get a substantial discount on registration; inquire at firstname.lastname@example.org.
