Robert A. Freitas Jr. brings to our attention a major step on the road to advanced nanotech, published a couple weeks ago in Science (abstract). He writes: This paper reports purely mechanical-based covalent bond-making and bond-breaking (true mechanosynthesis) involving atom by atom substitution of silicon (Si) atoms for tin (Sn) atoms in an Sn monolayer… Continue reading Mechanosynthesis with AFM as a step toward advanced nanotechnology
By nearly eliminating the light lost to solar cells by reflection, a nanotech coating promises to increase solar cell efficiency.
A better understanding of how biomineralization converts ordinary minerals to biological mineral structures with extraordinary hardness and fracture resistance may lead to superhard materials for nanotech applications.
You might think that by now the definitions of terms like “nanotechnology” and “nanosystems” would be firmly established. In fact the process of arriving at an international consensus is more difficult than you might expect. Representing Foresight in the effort to define these and other terms is David R. Forrest, Ph.D., President of the Institute… Continue reading Defining international standards for nanotechnology
Nanoparticles can introduce two very promising, but easily degraded, therapeutic molecules into a laboratory model of human skin, and together they are much more effective than either is alone is slowing the development of deadly melanoma skin cancer.
Organisms that live in extreme environments may provide building blocks for nanotech applications that need to withstand extreme environments.
On 5 June 2008, Robert Freitas and Ralph Merkle of the Institute for Molecular Manufacturing (IMM) submitted to IEEE Spectrum the following response to the article “Rupturing the Nanotech Rapture” by Richard A.L. Jones (IEEE Spectrum, June 2008 issue). Their brief letter is reproduced below because Spectrum has chosen to publish only one of the… Continue reading Research challenges for the diamondoid mechanosynthesis path to advanced nanotechnology
A noninvasive Raman microscope has allowed scientists to track carbon nanotubes injected into living mice.
A practical nanotech method for integrating single-wall carbon nanotubes (SWNT) with existing silicon microtechnology could lead to uses in microelectronics, field emission displays, electronic memory devices and solar cells.
