The emerging ability to control the sizes of these clusters to atomic precision affords new opportunities for designing novel catalysts.
Atoms or molecules could be pumped through the spinning inner CNT to form patterns of atoms or molecules—a nanotech inkjet printer.
Researchers have developed a method of producing titanium oxide crystals with more reactive surfaces.
Can online gamers add to the nanotech toolkit for perfecting the de novo design of proteins that do not exist in nature?
Preliminary theoretical calculations show that it might be possible to develop a nanotech application in which clusters of a few boron atoms connect very small graphene semiconductors to make nanoelectronic devices.
A new nanotech method of measuring “blurred” molecular motions promises to improve the accuracy of molecular motion simulations.
Snowbird, Utah is the place to be for nanotechnologists on April 22-25 for the 5th Annual Conference on Foundations of Nanoscience (FNANO08): Self-Assembled Architectures and Devices. Those of you who have attended Foresight research conferences will recognize a number of familiar names and lots of new ones. Mark Sims of Nanorex tells us that they [...]
By combining more precise core-shell nanoparticle synthesis techniques with electronic structure theory to predict the properties of nanoparticles, nanotechnology researchers have produced a better catalysts for fuel cells.
There’s still time — barely — to plan to attend next week’s 1st Annual Unither Nanomedical & Telemedical Technology Conference in Quebec. Co-chair is Martine Rothblatt, PhD, of Unither Biotech. Speakers include these names familar to Foresight members, as well as many nearer-term topics: Tad Hogg, PhD — Member of the Research Staff: Hewlett-Packard Laboratories, [...]
A major milestone along the protein design path to productive nanosytems and advanced nanotechnology has been achieved—the design by computational methods of enzymes that catalyze reactions for which biological enzymes do not exist.
A developing understanding of non-Watson-Crick interactions places RNA nanotech on a firmer foundation.
Nanotech drug delivery vehicles may soon improve because it turns out that even those that appear to be promising are not well-designed.
In a virtuoso demonstration of nanotechnology, researchers used a scanning tunneling microscope (STM) to build walls of carbon monoxide molecules to confine electrons on a copper surface so that they resonate like a drum.
French nanotech researchers have used theory to increase the precision of carving with electron beams enough to remove individual atoms from single walled carbon and boron nitride nanotubes.
DNA-based construction is one of the major contenders on the pathway to atomically-precise manufacturing, and Caltech has made an important advance in that direction. From New Scientist: A group at the California Institute of Technology, led by biomolecular engineer Niles Pierce, has created a DNA-based fabricator. This is a system that allows the team to [...]
From Physorg.com, a description of some theoretical nanotechnology work that could lead to more efficient molecular machines: …R. Dean Astumian, a Physics Professor at the University of Maine, has recently proposed a concept in which molecular machines can operate arbitrarily close to chemical equilibrium at every instant of the cycle, and still perform work at [...]
A post by Roland Piquepaille on ZDnet further exploring a topic recently covered here: nanoscale robotic devices for medical applications. The site allows you to indicate whether you want this subject covered in the future or not. Excerpt: The idea of using nanorobots to deliver drugs and fight diseases such as cancers is not new…But [...]
Foresight members will recognize the names of researchers Robert Freitas and Tad Hogg. These two in the U.S. have now teamed with others from Australia to model nanotechnology robotics for medical applications, as described at PhysOrg.com. Excerpts: Virtual 3D nanorobots could lead to real cancer-fighting technology From eliminating the side effects of chemotherapy to treating [...]
