Institute of Nanotechnology Small world by Ralph C. Merkle Xerox PARC 3333 Coyote Hill Road Palo Alto, CA 94304 merkle@xerox.com This is an extended web version of the article published in the Feb/Mar 1997 issue of MIT Technology Review. This version has greater technical detail and embedded links. Introduction Manufactured products are made from atoms. Since we first made stone tools and flint knives we have been arranging atoms in great thundering statistical heards by casting, milling, grinding, chipping and the like. That's changing. Build products with almost every atom in the right place. One warning: in contrast to the useage in this article some researchers use the word "nanotechnology" to refer to high resolution lithographic technology while others use it to refer to almost any research where some critical size is less than a micron (1,000 nanometers). There are two main issues in nanotechnology: What might molecular manufacturing systems look like? The advantages ofnanotechnology The advantages of positional control
This article discusses the extensive range of 4 Important Rare Earth Elements Sir William Crookes, a 19th century British chemist, once wrote that, "rare earth elements perplex us in our researches, baffle us in our speculations and haunt us in our very dreams." These weren't easy elements to isolate or to understand, and so there was a very long lag time between the discovery of the rare earths, and the discovery of practical uses for them. It didn't help that individual rare earth elements don't occur by their lonesome—they travel in packs. To get one, you have to mine all of them. At first, industry didn't even bother to separate out individual rare earths, instead using them in a blended alloy called mischmetal. Europium was the first isolated, high purity rare earth element to enter the public marketplace, in 1967, as a source of the color red in TV sets. At the time, rare earth mining wasn't even a twinkle in China's eye.
nano tech 2012 International Nanotechnology Exhibition & Conference 11 Predictions for the World in 2030 That May Sound Outrageous Today but not in the Future. - I Look Forward To All futurism is speculation. It's time someone made some claims. I've picked developments I honestly consider plausible. Alright, crystal ball time: 1. A tiny computer that fits in your ear, and translates what you hear into your own language? 2. Aubrey de Grey says: I think we have a 50% chance of achieving medicine capable of getting people to 200 in the decade 2030-2040. 3. The eradication of extreme poverty will happen in our lifetime. 4. Soil-based agriculture is so passé. 5. I'm sure you've dreamed it: Getting into a car, kicking your shoes off and leaning back with a good movie and a cold beer while your self-driven car takes you safely to your destination, without your having to worry about directions or pedestrians. 6. I actually think this is a conservative estimate. 7. Probably a lot sooner, actually. 8. 9. 10. Today, 90% of people in the UK and 80% of Americans live in cities, while in China only 46% do. 11.

Overview of Nanotechnology Nanotechnology draws its name from the prefix "nano". A nanometer is one-billionth of a meter—a distance equal to two to twenty atoms (depending on what type of atom) laid down next to each other. Nanotechnology refers to manipulating the structure of matter on a length scale of some small number of nanometers, interpreted by different people at different times as meaning anything from 0.1 nm (controlling the arrangement of individual atoms) to 100 nm or more (anything smaller than microtechnology). At the small end of this scale, the structure is controlled to atomic precision—each atom is exactly where it should be for the optimum function of the material or the device. The Foresight Institute is focused on this small end of the scale: atomically-precise manufacturing or "molecular manufacturing". Life is the Existence Proof for Atomically Precise Technology Chemistry has of course always worked with atomic precision. Building to Atomic Precision
The Biomechanics of Good Running | Playbook AUSTIN, Texas — If you’re a runner and you can’t extend your hip well behind you on your stride, Jay Dicharry has bad news: You’re never going to be a great runner. [bug id="sxsw2012"]This doesn’t mean you should hang up your shoes. You can still run, and run well, but not everyone can attain the ideal stride needed to be a truly great runner. Dicharry is the director of the Speed Performance Clinic and the Motion Analysis Lab Coordinator At The University Of Virginia. In discussing the biomechanics of running here at South by Southwest Interactive he recalled his Louisiana roots to emphasize his point. “I’m from New Orleans, and there’s great food there,” he said, by way of understatement. Most runners don’t extend their hips, Dicharry said. Along with a lack of hip extension, overstriding is one of the biggest sins. “Look at their gait,” he said. Only Andrews maintained textbook form for the whole race, finishing first in 1:44.71, just .01 off the meet record. Third, kneel on one knee.
Tiny brains created from SKIN could lead to cures for disorders like schizophrenia and autism Scientists used stem cells to grow 3D tissue that mimics a brainThe cells displayed an organisation similar to that seen in the early stages of the developing human brain's cerebral cortex - also known as grey matterThe miniature brains helped the researchers identify a defect that affects normal brain development in microcephaly leading to a smaller brainThe findings could eventually lead to treatments for other neurological disorders By Emma Innes Published: 18:19 GMT, 28 August 2013 | Updated: 00:00 GMT, 29 August 2013 A ‘brain in a bottle’ has been grown by stem cell scientists who hope it will lead to treatments for neurological and mental diseases. The ‘organoids’, three to four millimetres across, have a structure similar to that of an immature human brain. The goal was to produce a biological tool that can be used to investigate the workings of the brain, better understand brain diseases, and test new drugs. ‘These structures are not just peculiar lab artefacts.
'Fabbers' could launch a revolution Lindsay France/University Photography Hod Lipson, assistant professor of mechanical and aerospace engineering, right, and engineering graduate student Evan Malone work with a Fab@Home machine in the Computational Synthesis Lab in Upson Hall Feb. 22. On the stage is a Lego tire duplicated by the Fab@Home. The Altair 8800, introduced in the early 1970s, was the first computer you could build at home from a kit. Hod Lipson, Cornell assistant professor of mechanical and aerospace engineering, thinks a little machine he calls a Fab@Home may have the same impact. Some day, Lipson believes, every home will have a "fabber," a machine that replicates objects from plans supplied by a computer. Such machines could evolve from the 3-D printers currently used by industrial engineers for "rapid prototyping." Lindsay France/U. "Fabbing" a Lego tire. Provided The Lego tire on the vehicle. Some recent developments: A high school student in Kentucky is "fabbing" chocolate bars.
