Nominate your favorite nanotech researcher for the Feynman Prize, deadline June 30: http://www.foresight.org/prize/feynman.html
Detailed calculations show that electrons passing through a 'turbine' in which one type of carbon nanotube (CNT) is suspended inside another type of CNT would cause the inner CNT to rotate, forming an electron 'windmill' or turbine. The researchers also suggest that atoms or molecules could be pumped through the spinning inner CNT to form patterns of atoms or molecules—a nanotech inkjet printer…
Foresight Event – Vision Weekend
Two different types of nanostructures have been reported as nanotech methods to clean up oil spills and other organic pollutants. Researchers at MIT have developed a nanowire mesh that can reversibly absorb 20 times it weigh in oil. Researchers at Rice have shown how specially designed "nanobatons" can trap oil droplets by spontaneously assembling into sacs…
Chemists have designed molecules that act like nanotech sensing robots by signaling information about their chemical environment…
The combination of electrical stimulation and a nanotech surface composed of carbon nanotubes dispersed in polycarbonate urethane was found to attract cartilage-forming cells, which might lead to a treatment to regenerate lost or damaged cartilage…
One of the most promising applications of near-term nanotech is the production of nanostructured materials for use in energy applications, like less expensive solar cells. Nanostructured materials can prove superior in surprising ways. Here carbon nanotubes with the proper imperfections were found to replace more problematic and expensive materials in dye-sensitized solar cells…

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.
Foresight note: One free conference ticket is available to a Foresight Senior Associate only for each of the following two conferences. Please contact Alicia Isaac either at email@example.com or by phone 650.289.0860.
Following the huge success of our inaugural conference which attracted over 200 delegates, NanoCentral® and IntertechPira are pleased to bring you NanoMaterials08. Taking place between 7-9 July at the Newcastle Marriott Hotel, this is the only event of its kind to focus on the commercialisation of nanomaterials. NanoMaterials08 is made up of poster sessions, workshops, exhibitions, a conference and social programme, and will feature a variety of national and international companies active in the nanomaterials revolution. With over 400 attendees expected, this event will provide excellent networking and learning opportunities, and is not to be missed.
Nanotech Northern Europe 2008
Nanotech Northern Europe brings together the field's top scientists and leading international companies in order to advance the beneficial use of nanotechnology. The 2008 event concentrates around three application areas:
The program also features sessions on:
