The AMO nanoelectronics group of Dr. Max Lemme was able to manufacture top-gated transistor-like field-effect devices from monolayer graphene. A conventional CMOS-compatible process has been applied to fabricate a graphene field-effect device – a transistor made from a monolayer of carbon. The observed mobility in the devices exceeds the universal mobility in silicon MOSFETs. Furthermore, …
Experts are already duelling over the whether the machine will work. I think the arguments are irrelevent because Dwave has already been fully funded. They will make money when they scale this up this year and next year and make it faster than other methods. So the difference with the cold fusion claim is that …
A software patch could make modern cars 2.6% more efficient Once it is determined to be not overly damaging to batteries then it would be ready for widespread use. The software deactivates the dynamo when it is particularly inefficient for the engine to power it, thus improving the overall efficiency of the engine. Brian WangBrian …
Engines of Creation 2.0: The Coming Era of Nanotechnology – Updated and Expanded is available for free at wowio.comIt has a new look and feel and includes updated information from Eric Drexler. It also includes the Drexler / Smalley debates and comments on the debate. Brian WangBrian Wang is a Futurist Thought Leader and a …
An item related to my port security article, as we get better at catching a larger fraction of the illegal traffic in nuclear materials and dual use materials like beryllium and zirconium a computer model can piece together the partial information on traffic flows to determine who is working on a nuclear bomb and where …
Some physicists have argued that the universe is doomed to be ripped apart by runaway dark energy, while others think it is bouncing through an endless series of big bangs and big crunches. Now these two ideas are being combined to create another option, in which our universe ultimately shatters into billions of pieces, with …
A robotic exoskeleton controlled by the wearer’s own nervous system could help users regain limb function, which is encouraging news for people with partial nervous system impairment, say University of Michigan researchers. The ankle exoskeleton developed at U-M was worn by healthy subjects to measure how the device affected ankle function. The U-M team has …
Researchers have developed a comprehensive, inexpensive and simple way to put DNA into nanoscale troughs. Using techniques typically reserved for the manufacture of computer chips, the Wisconsin team fabricated a mold for making a rubber template with slits narrow enough to confine single strands of elongated DNA. The new technique is akin to threading a …
MIT researchers have developed a computer chip that runs on microbubbles like these. Photo courtesy / Manu Prakash From physorg, in work that could dramatically boost the capabilities of “lab on a chip” devices, MIT researchers have created a way to use tiny bubbles to mimic the capabilities of a computer. A colored montage of …
Port security technology review with a focus on current and anticipated systems related to finding nukes and nuke materials in shipping containers (about 70 million containers per year). Millimeter radiation and advanced X-ray scattering analysis images appear to provide images detailed enough so that a 30 cm block of lead would stand out. Since 2002 …
Advancedment towards optical frequency combs False-color images of the “fingerprints” of molecular iodine, each taken under different experimental conditions using a NIST frequency brush created with an ultrafast visible laser. The squares within each frame reveal the frequency and intensity of light from individual “bristles” of the brush. The variation in the colors reveal where …
