20 years ago, in the wake of the cold fusion excitement-turned-debacle, I noticed an interesting fact. The people doing the experiments were divided into two classes: The electrochemists who believed that fusion was happening were doing their experiments in plastic tubs and glassware, whereas the physicists who believed that no fusion was really happening were [...]

Jeriaska has made available videos of presentations from Convergence08, held on November 15-16, 2008 in Mountain View, California, to examine the convergence of NBIC (Nano-Bio-Info-Cogno) technologies. Among those of special interest to Nanodot readers: Mapping a Cone of Uncertainty, Paul Saffo Convergence: Artificial Intelligence Panel, Peter Norvig, Steve Omohundro, Ben Goertzel, Barney Pell Convergence: Synthetic [...]
The discovery that nitrogen-doped, metal-free carbon nanotubes make better electrodes than do platinum nanoparticles may open the way for inexpensive nanotech fuel cells.
Canadian scientists have discovered how chemical structure can elicit a quantum state that permits the ultrafast movement of energy along an organic polymer.
A method that eliminates metallic single walled carbon nanotubes from mixtures leaving fully functional semiconducting SWCNTs may open the way for various nanotech applications that require pure semiconducting SWCNTs.
An open-access review article describes how a layer of nanoparticles of different sizes, compositions, and shapes enhances the efficiency of thin-film solar cells.
If you have a proposal on how nanotech could address a critical national and societal need, the National Institute of Standards and Technology (NIST) wants to hear from you.
The following is an edited and revised version of the talk I gave at the Global Catastrophic Risks conference that was held in conjunction with Convergence 08 (and which I reprised for Convergence). I’m posting it here because it seems to me that this is exactly the kind of thing Foresight was founded for: to [...]
A nanostructure called a “gyroid” provides the basis for a more efficient, inexpensive nanotech solar cell.
The publication of a method to mass produce graphene has opened the way to further study of this remarkable nanomaterial.
By nearly eliminating the light lost to solar cells by reflection, a nanotech coating promises to increase solar cell efficiency.
Combining electrically conductive polymers, transition metal atoms, and spin-coating to form thin films could lead to solar cells with two major advantages that would make them more efficient at converting light to electricity.
Nanotech pathways to a sustainable energy economy are generating a great deal of interest in Europe.
Chemically modified graphene has found in manganese oxide nanoflower/carbon nanotube array a rival nanotech material to improve energy storage using ultracapacitors.
Chemically modified graphene (CMG) may lead to ultracapacitors that can store about twice as much electrical charge as is possible with current commercially available materials.
A very powerful electron microscope capable of resolving single gold atoms has revealed why some gold nanoparticles work and some don’t.
