Conference video: Nanoscale Materials, Devices, and Processing Predicted from First Principles

Prof. Goddard addressed some of the method developments to allow modeling of large-scale systems, followed by some examples. He noted that the grand vision over the past 25 years has been that theory can be used to predict something useful. To predict new systems where there is no empirical data it is necessary to start with first principles. …

Conference video: Mythbusting Knowledge Transfer Mechanisms through Science Gateways

Prof. Klimeck addressed novel ways to disseminate nanotechnology simulations to broader audiences using as an example a user facility, the web site nanoHUB. About 12,000 users sign up for accounts and run half a million simulations throughout the year. …

DNA nanotechnology controls which molecules enter cells

A useful addition to the toolkits for nanomedicine and synthetic biology would be a cell membrane pore to exclude or admit predetermined molecules on demand. …

Molecular arm grabs, transports, releases molecular cargo

… UK chemists have devised a nanoscale robot that can grasp a cargo molecule, pick it up, place it in a new position some distance away and release it. At no time does the cargo dissociate from the machine or exchange with other molecules. …

Electron tomography reveals precise positions of individual atoms in aperiodic material

As researchers work to build increasingly complex structures and devices to atomic precision, it will become increasingly useful to be able to image arbitrarily complex 3D nanostructures to atomic precision. This was a challenge that Richard Feynman threw out to electron microscopists in 1959, and UCLA scientists appear to have decisively met Feynman’s challenge. …

Nanoparticles ameliorate MS in mice by inducing immune tolerance of myelin

Nanoparticles fabricated by a variety of techniques offer great hope for the development of nanomedicine. One of the potential applications for specially engineered nanoparticles is the modulation of an immune system that is targeting an essential molecule, as explained by this news release from Northwestern University …

Inexpensive transparent conductors from correlated metal nanostructures

It is usually both interesting and useful when technology identifies multiple paths to the same goal, particularly when a new path has a major advantage, such as a much lower cost and substituting an abundant resource for a limited one. …

Active and reversible control of nanoparticle optical properties

Nanoparticles exhibit a range of useful electronic, optical, and magnetic properties. These particles would be even more useful if such properties could be deliberately and reversibly tuned for specific purposes. Scientists have now achieved substantial progress in this direction. …

We will continue to be a growing force enabling businesses, scientists, technologists, policy makers, investors, and individuals to be informed about how nanotechnology can contribute to a better future.

Thanks to a generous $40,000 Challenge Grant, every contribution you make to Foresight is matched dollar-for-dollar to that amount. Donations and memberships sent by December 31 qualify as 2015 tax deductions. For extra tax savings, donate appreciated stock.

About the Foresight Institute
Foreseeing Future Technologies

Advancements in technologies such as nanotech, robotics, artificial intelligence, and biotech are promising to make major differences in our lives in the not-too-distant future, as the Industrial Revolution did to the agrarian world — to do for the physical world what the computer and Internet have done to the world of information.

Since 1986, the Foresight Institute has been in the forefront of a worldwide community of visionaries who work to help shape these possibilities into a positive, beneficial reality.

If you would like to help us understand the potential of these technologies, and influence their direction, please consider becoming a member of the Foresight community. With your support, Foresight will continue to educate the general public on these technologies and what they will mean to our society.

The Foresight Institute is a non-profit, member-supported 501(c)(3) organization. We offer membership levels appropriate to meet the needs and interests of individuals and companies. Donations are tax deductible.

Donating to Foresight

For information on membership go to: http://foresight.org/members/index.html
