Atomic precision as the goal of nanotechnology

Nanotechnology Enables Real Atomic Precision is the title of a piece by Susan Smith in Desktop Engineering, which includes comments by longtime Foresight Senior Associates Steve Vetter and Tihamer Toth-Fejel: While nanotechology might mean different things to different people, the term was originally coined to describe the building of things from the bottom up with… Continue reading Atomic precision as the goal of nanotechnology

A cautionary note, concluded

Last week I posted a story of strange behavior in the simulation of molecular machines. One commenter asked if this was due to something unusual in the starting configuration of the atoms. This was the first thing we investigated, and didn’t seem to be the case. There was a small amount to strain energy in… Continue reading A cautionary note, concluded

UK/China team aim at molecular rotors to generate current

EurekAlert reports work by the University of Liverpool and Chinese Academy of Sciences: New rotors could help develop nanoscale generators In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at… Continue reading UK/China team aim at molecular rotors to generate current

Hardware –> Software

An interesting question was posed to my “Do the math” post of last week: What does this have to do with nanotechnology? A little history helps, as usual. Eniac plugboard: Hardware or software?

Feynman Prize nominations now open, also Communications, Student Prizes

Nominations are now open for the Foresight Institute Prizes for 2009, due June 30. Our best-known prizes of course are the two annual Foresight Institute Feynman Prizes in Nanotechnology, one for Experiment and one for Theory: Description Instructions Also open are nominations for the Foresight Prize in Communications: Description Instructions And the Student Prize: Description… Continue reading Feynman Prize nominations now open, also Communications, Student Prizes

Negative resistance

If you connect a 12-volt battery to a 4-ohm lamp, 3 amps of current will flow through the circuit by Ohm’s Law, V=IR. Power = VI = 36 watts will be dissipated by the lamp. If you add a 2-ohm resistor in series with the lamp, the resistances add to 6 ohms, the current is… Continue reading Negative resistance

DNA nanorobot walks without intervention along rigid track

Scientists have succeeded in coordinating the movements of the biped’s legs so that it can walk in one direction along a DNA track without the need of intervention at each step.

Protein design revolution points toward advanced nanotechnology

Scientists at the University of Pennsylvania used basic engineering principles derived from studying natural proteins to design from scratch a simple and small protein that performed the function of carrying oxygen that is performed by natural globin proteins.

A DNA nanotechnology road to molecular assembly lines?

A piece in The Christian Science Monitor compares Nadrian Seeman, founder of the field of structural DNA nanotechnology and winner of the 1995 Foresight Feynman Prize in Nanotechnology, with Henry Ford—implying that his recent accomplishment with his collaborators in creating a two-armed DNA nanorobot could point to a role for DNA nanorobots in future nanotech… Continue reading A DNA nanotechnology road to molecular assembly lines?

A nanotechnology route to quantum computers through hybrid rotaxanes

A major advance in molecular machine fabrication allows the construction of rotaxane molecular shuttles in which organic and inorganic components are mechanically linked in the same molecular structure.
