Nanosystems for India

May 6, 2011

Wiley India publishes textbooks “catering to the needs of Indian students”, and now offers Nanosystems:  Molecular Machinery, Manufacturing, and Computation, the book I wrote on the principles and potential components, architectures, and implementation pathways for high-throughput atomically precise manufacturing systems.
Here’s a list of Indian distributors.
Wiley India, a branch of John Wiley & Sons, the original [...]

Molecular machine animations
in the New York Times

November 16, 2010

The New York Times has an article, “Where Cinema and Biology Meet”, on the recent high-quality animations of biomolecular machines.
The author, Erik Olsen, highlights Drew Barry as the Steven Spielberg of the field:
Mr. Berry’s work is revered for artistry and accuracy within the small community of molecular animators, and has also been shown in museums, [...]

Molecular Mechano-Electronics

June 21, 2010

Pulling on the ends of a cobalt complex that bridges an electrical junction (as illustrated) changes the geometry of the coordinating ligands, hence the energies of electronic spin states, hence (as it turns out) the low-temperature electrical resistance of the junction. The authors of the paper cited here look toward potential applications for devices that [...]

A programmable nanoscale assembly line

May 20, 2010

When I picked up my copy of this week’s Chemical & Engineering News this evening, I found that the lead article begins with this:
Futuristic visions of nanobots that travel the body to treat disease and construct compounds one atom at a time got a little closer to reality this week, thanks to two advances in [...]

Cell-free synthetic biology

February 12, 2010

Synthetic biology doesn’t require cells, and in several ways, cells are liabilities.
Cells can make engineering difficult. Cell membranes and bacterial walls stand between new genes and the machinery needed to transcribe and translate them. They are barriers to liberating gene products. They contain systems that are complex products of eons of evolutionary history, not systems [...]

Molecular Manufacturing:
The NRC study and its recommendations

January 7, 2010

Part 6 of a series prompted by the recent 50th anniversary of Feynman’s historic talk, “There’s Plenty of Room at the Bottom”. This is arguably the most important post of the series, or of this blog to date.
Topics:
— The most credible study of molecular manufacturing to date
— The study’s recommendations for Federal research support
— The [...]

“There’s Plenty of Room at the Bottom”
(Richard Feynman, Pasadena, 29 December 1959)

December 29, 2009

“Feynman’s 1959 talk, entitled ‘There’s Plenty of Room at the Bottom’”, was delivered 50 years ago today, and the words I’ve quoted above are the first words in the first sentence of the first paper I wrote, almost 30 years ago, on what later became known as “nanotechnology”. Feynman read and discussed the paper with [...]

What can scaling laws
tell us about nanomachines?

October 14, 2009

I recently posted my MIT doctoral dissertation, which (like my book on Nanosystems) discusses scaling laws in an introductory section.
The scaling laws inherent in geometry, classical mechanics, and the properties of materials can tell us a lot about what to expect from nanoscale systems. In particular, they show why an advanced mechanical nanotechnology can [...]

Molecular Nanomachines: Physical Principles and Implementation Strategies

October 1, 2009

I’ve migrated another paper to E-drexler.com:

Drexler, KE. “Molecular Nanomachines: Physical Principles and Implementation Strategies”, Annual Review of Biophysics and Biomolecular Structure, 23:377-405 (1994).
(With thanks to Robert Bradbury for the original HTML conversion.)

The Physical Basis
of High-Throughput
Atomically Precise Manufacturing

June 12, 2009

The section below, adapted from a longer work, discusses the physical basis for understanding atomically precise fabrication systems: first, a very general class of systems, and second, the specific characteristics of high-throughput systems of a kind several technology levels above where we are today. (In my previous post, “A Telescope Aimed at the Future” I [...]

The Casimir Effect and Nanomachines

April 20, 2009

The Casimir effect can be viewed as a manifestation of the quantum-mechanical zero-point energy of the vacuum, and has recently been hyped as if it were something new and mysterious that will assist or maybe ruin advanced nanomechanical systems. It has inflamed the minds of something-for-nothing energy enthusiasts, too.
In reality, what Casimir described is a [...]
