Nanojets

from the really-tiny-scrubbing-bubbles dept.
GinaMiller (and others) wrote "Simulation shows that liquid jets a few nanometers in diameter might have the potential to produce ever-smaller electronic circuitry, inject genes into cells, or etch tiny features. Writing in the August 18 issue of Science, Georgia Tech researchers suggest that jets as small as six nanometers in diameter may be possible — though they will require special conditions to operate and be sensitive to effects not of concern to macroscopic jets. As a next step, the researchers would like to create nanojets experimentally and use them to apply patterns that could replace current lithographic processes in the manufacture of nanoscale miniaturized circuits. They could potentially also be used as "gene guns" to insert genetic materials into cells without causing damage. The researchers produced some nice graphics "

Open Source CAD code for MEMS

from the where-oh-where-is-good-software dept.
Senior Associate Michael Butler writes "At the just-past Foresight Gathering, mention was made of extant MEMS fab CAD software packages and how bad they are. Alternatives mentioned include, e.g., recycling mature finite element FORTRAN code and stitching it together with other things. It happens that Matra open sourced a bunch of CAD/CAM code last year. (Slashdot article). I suggest that interested people at Zyvex and elsewhere check out Open Cascade and see if what they're doing can be bent to your purposes. Have any nanodotters worked with this code?

Nanotubes best heat conductors

from the who-needs-metals? dept.
Senior Associate Brian Wang writes "University of Penn scientists have found that carbon nanotubes are the best heat conductors. Sound can conduct thermal energy at 10,000m per sec down the tubes. They could be very useful as heat sinks in chips. The weak binding between tubes that allows the heat conductance must be overcome in order for strong materials to be created from thicker structures: http://www.eurekalert.org/rele ases/up-iac083000.html"

Nano@HOME project proposed

from the more-fun-than-SETI dept.
Senior Associate Robert Bradbury writes "In the large group meeting, at the very end of the Foresight Spring 2000 Senior Associates gathering , I made a brief statement about the need for a Nano@HOME project. Available now is some background rationale and relevant links in the Nano@Home Project Proposal. This relates to Bryan Brun's recent proposal for open sourcing nanotech, discussed here, as well as possible methods the Foresight Institute and/or IMM could use to generate more public support for nanotechnology and even potential revenue sources."

Protective cage for nanoscale structures

from the behave-or-be-caged dept.
bbrelin brings to our attention work at Purdue in which 10-40 nm structures are "caged" to protect them from unwanted reactions. Now used for metal clusters, such a process may be useful in protecting more complex nanodevices:
"Scientists are trying to use these to build new, stronger materials one molecule at a time for applications ranging from medicine to aerospace. But this bottoms-up approach has had a downside: Nanoparticles can be so fragile and unstable that if their surfaces touch, they will fuse together, losing their special shape and properties…The porous coating permits the particle inside to interact with substances outside, but keeps the nanoparticles from interacting with each other."

Nanotechnology and plasmonics may lead to faster computers

Plasmonic nanoswitches based upon molecular machines may eventually lead to nanotech plasmonic circuits.
