PANEL — “The Scientific Challenges of Truly Transformative Nanotech” Andrew Bleloch, (Halcyon), Matt Francis (UC-Berkeley), Sir J Fraser Stoddart (Northwestern), William Goddard (CalTech), Chris Schafmeister (Temple) Tough to characterize and see what you are working on. Takes a long time Interface control is tough Molecules have to be put together with the other materials to …
“Integrating Molecular Switches and Machines with the Everyday World” Sir Fraser Stoddart, PhD, Head of Northwestern’s Mechanostereochemistry Group 875 papers and publications Briefly reviewed his work 1981 to 1998 to make a molecular switch Spread the switch onto monolayer Works with Jim Heath to work on crossbars electrochemical switching of the bistable catenane (2000) rotaxane …
“This is a totally new approach to cancer therapy,” said Professor Patrick Gunning of chemical and physical sciences (University of Toronto). “Everything prior to this has targeted functionally relevant binding sites. Our approach inhibits the mobility of cancer-promoting proteins within cells — essentially, it’s like molecularly targeted glue.” The “glue” is shaped like a dumbbell: …
Physics of Plasmas – Formation of a long-lived hot field reversed configuration by dynamically merging two colliding high-β compact toroids (H/T Talk Polywell Tri-Alpha energy (which has about $100 million in funding for field reversed nuclear fusion) had a paper in May 2011. Colliding toroids sounds like Helion Energy. This picture is from Helion, do …
The new electrochemical process (a) Schematic diagram of the cell for fabrication of carbon nanotubes (b) Scanning electron microscope image showing that the graphite electrodes are almost entirely converted to carbon nanotubes in the new process A team at Cambridge University is investigating whether nanotubes made with the new method could be used to improve …

A team of Virginia Commonwealth University scientists has discovered a new class of ‘superatoms’ – a stable cluster of atoms that can mimic different elements of the periodic table – with unusual magnetic …
A team of physicists at the University of Innsbruck, led by Philipp Schindler and Rainer Blatt, has been the first to demonstrate a crucial element for a future functioning quantum computer: repetitive error correction. This allows scientists to correct errors occurring in a quantum computer efficiently. The researchers have published their findings in the scientific …
James Woodward reviews the scientific history of inertia, gravity and Mach Effect at Centauri Dreams. What is Mach’s principle? Well, lots of people have given lots of versions of this principle, and protracted debates have taken place about it. Its simplest expression is: Inertial reaction forces are produced by the gravitational action of everything that …
1. Lawrenceville Plasma Physics is getting major improvement in repeatability of fusion yield and beam production. Repeatable fusion yield is now within a factor of 4 of predictions. Clues found from data and simulation on improving filamentation, ending the early-beam problem and boosting yield up to predictions. Any small deviation from symmetry greatly reduced yield …
Nature Photonics – 26 Tbit per second line-rate super-channel transmission utilizing all-optical fast Fourier transform processing There has been transmission of data at over 100 terabits per second but those involved up to 370 lasers. German scientists of Karlsruhe Institute of Technology have succeeded in encoding data at a rate of 26 terabits per second …
Mike Rowe of the Discovery Show Dirty Jobs was at Maker Faire in San Mateo, California Mike announced that he is trying to get a TV show developed around the theme of Making things. A goal would to popularize creative personal manufacturing. The Tech Shop are facilities with nearly $750,000 in advanced machines and tools …
