Picture of the day


utility fog Murray Robertson


Inspired by the original foglet designs of Dr. J. Storrs Hall (see "Utility Fog") Nanotechnology is a generic image created for the Royal Society of Chemistry, UK, "chemsoc timeline." This image is one of the most recognized "nanotch" images, and has been used extensively.

Murray Robertson is an artist who has been involved with the visualisation of ideas in science since 1998. You can see his work in "A Visual Interpretation of the Table of Elements." He is currently working on a new set of images based around nanotechnology/molecular computers.

Quote of the day

At an April (2003) conference sponsored by the National Nanotechnology Initiative, Mihail Roco, the nanotech guru at the National Science Foundation, noted, "Developments in nanotechnology are going much faster than expected; in fact, development time is less than half that we expected." Roco also flatly declared, "If a company does not enter nanotechnology now - in five years it will be too late - it will be out of business." (RR: my emphasis)

Molecular Manufacturing Issues

To start, let me say that the issues you will read about below are by no means all the issues. Molecular manufacturing is a very complex subject, one that is not easy to describe in simple terms or language. Opinion on it is divided, and emotions are charged. Intelligent, well-meaning individuals in various camps hold passionate views; pretty much what we should expect from a technology that holds huge potential.

When it comes to molecular manufacturing (MM) there are many influential groups, each with their own views, agenda and ability to influence stakeholders and policy makers. On some points they agree; on many they do not, and in some cases emphatically not.

And yes, I am biased towards a majority of the views held by one of the groups, and beliefs-tempered by the views of the others. They all offer points that should be considered. I disagree with some, and with some of their conclusions, but I’m willing to listen, debate, and change my mind if presented with convincing evidence.

So for this post, I am not trying to create an exhaustive "issues" list; I’d prefer, rather, to start a conversation with you by pointing out just some of them.

What they believe

One group holds that MM is either the Holy Grail of technology or possibly a means to our end. Another group is of the opinion that MM (as defined by the first group) will either never happen (because we’ll never develop it), or is so far into the future that it’s "no worries mates" for now. Yet a third group believes that all R&D into nanotechnologies should be halted until all potential harmful effects are know, understood, and preventative measures put in place. Another, that MM is just one of many advanced technologies that could lead to an unprecedented human evolution, accompanied by greatly extended life spans and vastly upgraded intellects. And finally, another, but by no means final group, believes MM is just one of many advanced technologies that could lead to all sorts of societal ills.

Frankly, it’s hard to get your hands around MM, let alone the points-of-view held by these and other stakeholders (AKA: interest groups. Once again, that’s you and I and everyone folks, the whole unorganized, confused, anxious and hopeful lot).

For the purpose of this exercise specific groups or individuals will not be named. Suffice it to say that someone holds views and beliefs that are consistent with the following questions.

Some of the important issues

     Is MM possible?
     If so, is it safe? If not, why not? (RR: of course, if your answer is "not" then the remaining questions are moot.)

     Is Grey Goo possible? (1)
     If so, how do we prevent/defeat it? If not, why not?

     Can we build the nanofactory? (2)
     If so, what are the steps leading to it, when might we see it, and what are the upsides and downsides to it’s development? If not, why not?

     Do we have sufficient safeguards in place to ward off the potential downsides and increase the likelihood of a positive MM-enabled future? (RR: here we will take a turn away from the script and say "as far as I know there is currently no group that believes MM is possible/likely that also believes that the answer to this Q is yes.")
     If not, what is being done to address this issue?

     Are business, government and individual stakeholders adequately informed regarding the myriad ways in which advanced technologies, including MM, may change our collective future?
     If so, why so many contradictory viewpoints? If not, why not?

     Are stakeholders learning about, participating in, and influencing the debate on MM?
     If so, in which venues? If not, why not?

I hope to enlist the aid of my friends and colleagues in the nano-space in providing answers to these questions. I will also post answers from those that present an opposing yet supported p-o-v. And I will probably answer a few myself, as time allows.

Of course I’ll post those of your comments and questions that meet blog etiquette standards.

I’ll leave you with this: You are a stakeholder (*), whether you believe it or not. When it comes to advanced technologies everyone on this beautiful blue marble is a stakeholder, all 6.5 billion of us. Do you have enough information to enable you to make good decisions about advanced technologies, including MM? If not, ask your questions here.

(*) stakeholder: a person or organization that has a legitimate interest in a project or entity. From Wikipedia, the free encyclopedia

Picture of the day


lanthanum aluminate Paul A. Midgley


This is a false colour convergent beam electron diffraction pattern recorded at 150kV parallel to the three-fold axis of lanthanum aluminate. In addition to the mesh of reflections at the centre, the pattern also shows concentric circles of reflections in successive higher order Laue zones. Odd numbered zones have only a single branch of intensity that corresponds to scattering solely from the oxygen atoms in the structure.

As with the previous picture, I will post the others in this series over time. To see it all now, visit the Nanotechnology Now Gallery.

Quote of the day

Molecular nanotechnology promises to usher in the next Industrial Revolution and replace our entire manufacturing base with a new, radically precise, less expensive, and more flexible way of making products. These pervasive changes in manufacturing will leave virtually no product, process, or industry untouched. To be sure, nanotechnology has the potential to disrupt entire industries while leading to the creative destruction of current business models. It has already dramatically changed the competitive landscape of many industries worldwide including advanced materials/composites, aerospace/defense, automotive, energy, life sciences, medicine, electronics and semiconductors. Yet the future potential of nanotechnology depends on creating the tools that will enable us to effectively position molecules and build complex structures with atomically precise control. Every aspect of basic nanoscale science and the commercial production of nanotechnology will rely---first and foremost---on the capacity of these tools, instruments, metrology devices, and modeling/simulation applications to measure, sense, fabricate, and manipulate matter at the atomic level.

Picture of the day


3-dimensional Si composite nanostructure Ghim Wei Ho and Prof Mark Welland


This 3-dimensional Si composite nanostructure is one of the most recognized "nanotech" images. It has been posted on several key websites and used as cover and interior art in several science magazines. When I first found it I was struck by it's underlying beauty; bleeding-edge tech meets 21st Century art.

At the time this image was created, Ph.D. student Ghim Wei Ho was doing research in the lab of Prof. Mark Welland. Her project involved the fabrication and characterization of novel nanostructures. "For the remainder of my Ph.D., I will be focussing on the potential device aspects of these extraordinary structures," she said.

I will post the others in this series over time. To see it all now, visit the Nanotechnology Now Gallery.
