Harder than diamond: Aggregated diamond nanorods

From PhysicsWeb: “Physicists in Germany have created a material that is harder than diamond. Natalia Dubrovinskaia and colleagues at the University of Bayreuth made the new material by subjecting carbon-60 molecules to immense pressures. The new form of carbon, which is known as aggregated diamond nanorods, is expected to have many industrial applications (App. Phys.… Continue reading Harder than diamond: Aggregated diamond nanorods

We'll watch nanotech experiments as they happen

Chemist Derek Lowe describes some amazing-sounding work at Caltech: “They’re taking electron microscope snapshots, one trillionth of a second at a time. And what is this technique good for? Well, electron microscopy has long been used for imaging all sorts of materials and biological samples. Fast freezing of the samples has revealed an extraordinary amount… Continue reading We'll watch nanotech experiments as they happen

Step toward building nanomachine-based 'materials that today just sound like science fiction'

To tell what’s really going on, read the abstract, but here’s the BBC version: Professor David Leigh, of the University of Edinburgh, said the demonstration was one of the first examples to show molecular machines integrating successfully with the macroscopic world… The tiny machines that coat the surface are essentially rod-like structures with rings that,… Continue reading Step toward building nanomachine-based 'materials that today just sound like science fiction'

Differential gear simulated, Drexler joins Nanorex

Even if you’re not technical, click through this link to see the excellent graphics: For the first time, a molecular dynamics simulation has been run on the Drexler-Merkle differential gear design. The simulation was done by Mark Sims, President and founder of Nanorex, with the nano-ENGINEER1 simulator using an MM2 force field. Sims responded to… Continue reading Differential gear simulated, Drexler joins Nanorex

CBEN: near-term nanotech for health and environment

Just back from a meeting of ICON in Houston (agenda in PDF format). I went out a day early to sit in on a meeting focused on Rice University’s CBEN, which included a high-level summary of their research plus some in-depth examples. Especially impressive was the research on gold nanoshells to treat cancer, and work… Continue reading CBEN: near-term nanotech for health and environment

From Texas A&M: nanotech to rapidly identify bacteria

From Texas A&M Engineering News: "A group of Texas A&M University researchers have developed a novel nanotechnology to rapidly detect and identify bacteria. Using a nanowell device with two antenna-like electrodes, the scientists can detect the electric-field fluctuations that result when a type of virus called a bacteriophage infects a specific bacterium, and then identify the bacterium present…'Our ultimate aim is to have a biochip where hundreds of nanowells and their preamplifiers are integrated. Each nanowell covers a different phage, and if a relevant bacterium is present, the corresponding nanowell will signal and identify the bacterium. This would be a pen-size biolab that would be able to identify hundreds of bacteria in five minutes.' "

Nanotube Transistors Assembled with DNA

JohnFaith writes " Here's an article from Technology Research News about tools being developed for designing DNA structures with carbon nanotubes. The DNA assembles into a matrix and the semiconducting carbon nanotubes form transistors in the spaces between the DNA. The work is happening at Duke , with more papers and info at Chris Dwyer's page. Interesting to see research that may provide arbitrarily complex 2D structures versus homogeneous films."

Collective Nanorobots Control Design

Adriano Cavalcanti writes "A new approach within advanced graphics simulations is presented for the problem of nano-assembly automation and its application for medicine. The problem under study concentrates its main focus on nanorobot control design for assembly manipulation and the use of evolutionary agents as a suitable way to enable the robustness on the proposed model. Thereby the presented works summarizes as well distinct aspects of some techniques required to achieve a successful nano-planning system design and its 3D simulation visualization in real time. http://www.nanorobotdesign.com"

nanosprings: nanoelectromechanical actuators

Dr. J.P. Singh writes "Nanostructures such as nanorods, nanowires and nanosprings are building blocks of future nanomachines and have potential applications in nanosensors and nanodevices. Due to their high structural flexibility and strength, nanosprings should be suitable for applications in nanoelectromagnetic sensors and devices. However, so far no electromechanically actuated nanosprings has been demonstrated. We demonstrated a nanoscale electromechanical actuator operation using an isolated nanoscale spring. The four-turn Si nanosprings were grown using the oblique angle deposition technique with substrate rotation, and were rendered conductive by coating with a 10 nm-thick Co layer using chemical vapor deposition. The electromechanical actuation of a nanospring was performed by passing a dc current through it using a conductive atomic force microscope tip. The electromagnetic force produces spring compression. See upcoming article in 10 May 2004 issue of Appl. Phys. Letts."

National Academies-Keck conference on Designing Nanostructures

Alex Cohen writes "We are in search of active researchers to attend the National Academies Keck Futures Initiative conference on Designing Nanostructures at the Interface between Biomedical and Physical Systems. The Futures Initiative conference provides an opportunity for researchers from different disciplines to focus on new questions in Nanotechnology. The conference provides a means for attendees to build collaborations and exchange ideas. Conference attendees are also eligible for Futures grants, which support interdisciplinary research. Invitees travel expenses are paid for by the National Academies Keck Futures Initiative."
