    Another one: "Atomic-scale manufacturing now a reality" phys.org/news/2018-05-atomic-scale-reality.html It's about this paper: "Autonomous Scanning Probe Microscopy in Situ Tip Conditioning through Machine Learning" researchgate.net/publication/3…_through_Machine_Learning I guess this needs to be combined with the R&D results which I've posted about recently here: Major improvement in STM control methodology.

    University of Oxford: "Postdoctoral Research Assistant in DNA Nanotechnology Applied to Molecular Additive Manufacture": link (Only applications received before 12.00 midday on 15 June 2018 can be considered.) More funding for APM by AMO: link ( AMO ...

  • Paper title: "On the effect of local barrier height in scanning tunneling microscopy: Measurement methods and control implications" doi.org/10.1063/1.5003851 I'll try to summarize in a reader friendly way. (I found abstract and conclusion of this paper not really satisfying.) One of the most serious issues with current STM microscopes is their tendency to fail on some more severe surface features like e.g. chemically highly reactive sites including dangling bonds. (Since I've once worked with an…

  • I've coded up a 3D printable version of this stuff: thingiverse.com/thing:2797168 sci-nanotech.com/index.php?att…326614b4e12625c065872ffb8

  • Primary press release: tum.de/en/about-tum/news/press…ses/detail/article/34408/ Paper (walled): science.sciencemag.org/content/359/6373/296 Video: (long url) Direct link to video: youtube.com/watch?v=K9fuSVaszyg I was very much waiting for these news. This will go into my list of archived milestones in the incremental path. Next up, to widen the data bottleneck, this needs to be electrically parallelized and combined with (nontrivial) nanomechanical demultiplexing. All that while reducing self a…

  • Name: "Mechanical Computing Systems Using Only Links and Rotary Joints" (Submitted on 10 Jan 2018) by Ralph C. Merkle, Robert A. Freitas Jr., Tad Hogg, Thomas E. Moore, Matthew S. Moses, James Ryley arxiv.org/abs/1801.03534 (There was a preceding report: imm.org/Reports/rep046.pdf) Essential points: +) extreme simplicity, only two elements, links and and 2D rotary joints +) (as the paper says): "All parts of the system can remain permanently connected and yet still provide all necessary combinat…

  • Great, IMO one of the most advanced and interesting things that are currently going on are the SW projects of Christian Schafmeister. Here's a presentation: youtube.com/watch?v=8X69_42Mj-g Then there also is: cadnano.org/ Which I haven't yet looked into. As for "Nanoengineer-1", AFAIK it has been abandoned by the original developers. Eric Drexler somewhere did mention a few details about the exact reasons (can't find it right away). I think the development ran into a dead end probably due to a c…

  • Just to let everyone know, I took an effort to dig up a large part of Eric Drexlers metamodern blog from the internet archive (all the date carrying pages). Here are the links: apm.bplaced.net/w/index.php?ti…from_the_Internet_Archive Lots of "gems" in there.

    Yeah, I've got info about this via the lifeboat foundation blog's google+ channel. Here: (A) # plus.google.com/+LifeboatFoundation/posts/7tAm7K4KVLn # lifeboat.com/blog/2017/09/scie…e.com&utm_campaign=buffer # scienmag.com/scientists-create…le-of-building-molecules/ # nature.com/nature/journal/v549/n7672/full/nature23677.html But your link has some info-graphics. A bit earlier another remotely related thing came in there too. This article here: (B) # plus.google.com/+LifeboatFoundation/posts/RtY…

  • I found a complete backup of the whole wise-nano wiki, archive.org/details/wiki-nano_wiseorg_w It says: "Last-updated-date 2014-02-08" Thus it's a little older than the last WaybackMachine snapshops that I had linked in the first post here. The backup can't be viewed without (nontrivial) installation though.

    I recently commented on this topic there: plus.google.com/+LifeboatFoundation/posts/V1ouSsTkA8C?hl=de I'll repeat that comment here slightly adjusted to fit the context of this discussion. I found these two open papers: informal overview: http://www.scs.illinois.edu/burke/files/highlights/pub32_Science.pdf details: scs.illinois.edu/burke/files/pubs/pub32.pdf (I've only read through the first one in detail yet.) Here's what this "molecule making machine" is about in essence: The the "Suzuki coupl…

  • Quote from Jim Logajan: “"Least problematic focus" appears to be a goal without a solid reason. If the audience is presumed to be that emotionally sensitive, exposure to non-linear mapping is probably an effort in futility. ” True, for a such a super sensitive audience that's likely "small-minded" enough to confuse physical size with significance, exposure to non-linear mapping may lead to severe psychological breakdown (exaggerating joke of course). I guess I have the problem of too many option…

  • I found an interactive version of nonlinear mapping: mrgris.com/projects/merc-extreme/ (Tip: turn on satellite view) What would be the most visually interesting while least politically, religiously, ideologically problematic place to focus at for a screenshot demonstrating that kind of the mapping? This is already hard. Additionally asking for a place that can be easily identified by most of the worlds population is probably too much and likely leaves no results.

  • broken citations ?

    I found some broken citations here: convergent assembly and its visualisation They don't link back to the source ( which I can't find in case of the citations from Chris (CHRISPHOENIX)'s posts ).

  • I just wanted to share some recent developments I find relevant: Two papers about interlocking DNA nanostructures: researchgate.net/publication/2…es_for_Functional_Devices nature.com/articles/ncomms12414 While still far from atomic resolution and still a little jelly floppy like this totally goes into the direction of stiff atomically precise nanorobotics. I hope that will convince more people that macroscale style machinery actually makes perfectly sense in the nanoscale. An image out of this p…

  • One more worry: I've recently checked for web activity of Josh Hall en.wikipedia.org/wiki/J._Storrs_Hall foresight.org/about/Hall.html (googles recent time filter) and only found total silence. And lots of dead links on his homepage: autogeny.org/ He doesn't look too healthy in this video: youtube.com/watch?v=J78Zy4WiKFU and mentions health problems here: foresight.org/nanodot/?p=3789 Sounds like circulatory problems and stroke. I hope he's all right.

  • Do you maybe have old links of Chris' blog for digging in the waybackmachine? I have even worse news: Drexlers blog "metamodern" broke down too. There was lots of highly valuable stuff. Just an example: metamodern.com/2008/12/27/towa…-nanosystems-materials-1/ web.archive.org/web/2016032801…-nanosystems-materials-1/ (maybe I'll edit in more here later)

  • I've looked a bit further into microfluidics and I now think that this technology will pretty much for certain play a major role in the development towards HT-APM. 3D printed microfluidics - in contrast to those very expensive and pretty big pipetting systems found at biomedical labs - allows at least one order of magnitude cheaper and thus much more accessible tinkering with natural self assembly (and of course "unnatural self assembly" too - the desired engineering type that's targeting toward…

  • When doing DNA origami to form lots of atomically precise nanoscale parts with different shapes/topologies there's the need to mix a lot of different combinations of a lot of different DNA oligomeres. AFAIK currently for such large scale mixing projects robotic pipetting systems are used that are not easily accessible. Microfluidic systems may have the potential to replace such huge and expensive robotic pipetting systems. Here's some new work investigating in how far cheap FDM printing can be u…
