Diamondoid nanotechnology

University of Ulster Scientists Make a Nanorod Breakthrough Engineers at the University of Ulster are the first researchers to create diamond nanorods with a diameter as thin as 2.1 nm, which is not only smaller than all the currently reported diamond 1D nanostructures (4-300 nm) but also smaller than the theoretical calculated value (2.7-9 nm)… Continue reading Diamondoid nanotechnology

Swimming nanomachines

From Nanowerk News: Rowland fellow Fischer devises spiral swimmer nanomachine Harvard researchers have created a new type of microscopic swimmer: a magnetized spiral that corkscrews through liquids and is able to deliver chemicals and push loads larger than itself. Though other researchers have created similar devices in the past, Peer Fischer, a junior fellow at… Continue reading Swimming nanomachines

Drexler's slides posted

Eric Drexler has posted the slides from his keynote talk at the Berkeley Nanotech Forum. These are a fairly painless way to get an overview of the Productive Nanosystems Roadmap.

Nano-boxes from DNA origami

Just a week ago I was at NIST to hear a talk by Paul Rothemund, winner of the 2006 Feynman Prize with Erik Winfree for the invention of DNA Origami. In just 3 years this has taken off in a big way. This story at Nanowerk News reports the latest: Danish researchers have made a… Continue reading Nano-boxes from DNA origami

Anisotropic semi-Dirac electrons in atomically-precise trilayers

In Arthur C. Clarke’s classic SF novel Against the Fall of Night, there is a description of the “moving ways”, the powered sidewalks on which people rode around the city, as being made of a material that would have baffled an engineer of our own times because it was solid in one direction and liquid… Continue reading Anisotropic semi-Dirac electrons in atomically-precise trilayers

Nanopumps

This article over at Ars Technica has a nice overview of some recent work showing that when water is forced through a nanotube of appropriate size, the polar nature of the water molecule lines them up so as to create a voltage along the tube. They show that such a tube can be used as… Continue reading Nanopumps

Replicating nanofactories redux

Over at Accelerating Future, Michael Anissimov continues the discussion about nanofactories. He says a number of reasonable things, but then mischaracterizes, or at least greatly oversimplifies, Foresight’s position on nanofactories and self-replicating machines in general: The general implied position of the Foresight Institute appears to be, “we’ll figure these things out as we go, MNT… Continue reading Replicating nanofactories redux

A Moore's Law for energy?

Earlier this week I was at the premiere of Transcendent Man, a biographical overview of Ray Kurzweil’s views on the coming Singularity. Kurzweil’s main argument is that the power of the exponential in technology is major, systemic, and underappreciated. The specific item of interest in this post is Kurzweil’s claim, repeated in the movie, that… Continue reading A Moore's Law for energy?

Self-replicating nanofactories?

Over at Accelerating Future, Michael Anissimov has a post about self-replication in which he seems to find it remarkable that Foresight, among others, can view a world containing mechanical replicators with aplomb: What is remarkable are those that seem to argue, like Ray Kurzweil, the Foresight Institute, and the Center for Responsible Nanotechnology, that humanity… Continue reading Self-replicating nanofactories?

Advancing nanotechnology by organizing functional components on addressable DNA scaffolds

Two recent publications provide more evidence of the growing capability of DNA scaffolds to support complex and interactive functions.
