Quiz Question:
What is wrong with this model of computation?

August 3, 2011

In the news today: “Governments, IOC and UN hit by massive cyber attack” (BBC) How did the attack work? In a mind-numbingly ordinary way: “An email would be sent to an individual with the right level of access within the system; attached to the message was a piece of malware which would then execute and [...]

My next book: Radical Abundance, 2013

July 21, 2011

I’m now working on a new book, Radical Abundance, scheduled for publication in 2013 by PublicAffairs. The book has a wide scope in both its content and intended audience, addressing scientists, a general reading audience, and thought leaders in the policy arena. Radical Abundance will integrate and extend several themes that I’ve touched on in [...]

An advance in atomically precise
building-block assembly

May 27, 2011

A paper in Science reports a design method that substantially advances the macromolecular technology base for building atomically precise nanosystems. Background: foldamer engineering As many readers know, biology shows an effective way build large, intricate, atomically precise systems: Use covalent chemistry to build chains of small building blocks, and design these chains to fold into [...]

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 Quantum Information Science
and Technology Roadmap
(for example…)

April 24, 2011

Roadmaps are crucial in developing new technology platforms — in other words, for the coordinated development of complete sets of compatible technologies that, taken together, support system-level technologies at a new level. Whether formal or informal, roadmaps address a fundamental problem of risk and mutual expectations in technology development: the problem of giving all necessary [...]

Atomic Layer Deposition
for Atomically-Precise Crystal Fabrication (2)

February 16, 2011

The American Vacuum Society writes to announce ALD 2011, the 11th International Conference on Atomic Layer Deposition: Atomic layer deposition (ALD) is a fast-moving frontier, profoundly impacting diverse applications and gaining momentum for industrialization and manufacturing, while leaving plenty of room for new science and innovation…. ALD is receiving attention for its potential applications from [...]

Updated post on high-throughput atomically precise manufacturing

August 23, 2010

I’ve updated “The Physical Basis of High-Throughput Atomically Precise Manufacturing”. Not a big change, but I expanded the discussion of reliable molecular modeling of selected, highly constrained systems, along the lines discussed here: “Making vs. Modeling: A paradox of progress in nanotechnology”.

Next up: Asteroids

July 4, 2010

Soon after Earth’s life first touched the Moon, NASA promised to make spaceflight routine and inexpensive, and I began studying the prospects for space as a genuine frontier. Geologists had analyzed the new, hard-won lunar samples, and I read up on the results in the local college library. Not nice: almost no carbon, nitrogen, or [...]

The molecular approach
to atomically precise fabrication

March 12, 2010

A few days ago, I wrote a brief sketch of the status and paths forward in the molecular approach to atomically precise fabrication. It offers a sampling, not a full picture:

Why fusion won’t provide power
   (at a reasonable cost)

January 20, 2010

The greatest problem with fusion power is rarely mentioned and scarcely on the research agenda: capital cost. When I discussed the problem earlier, in “Fusion Power: A New Way to Boil Water”, I hadn’t seen this quietly damning report, which I think is worth quoting: Issues and R&D needs for commercial fusion energy An interim [...]

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 [...]

The Molecular Machine Path
to Molecular Manufacturing (2):
Exploiting Improved Methods and Building Blocks

December 27, 2009

Part 4 of a series on the history and prospects of advanced nanotechnology concepts, prompted by the upcoming 50th anniversary of Feynman’s historic talk, “There’s Plenty of Room at the Bottom”. Rigid, structurally diverse bis-peptide oligomers C. Schafmeister, JACS, 2006 In this post, I’d like to outline the promise of fabrication technologies that are within [...]
