Electronic circuitry composed of nanowires can now be fitted to a surface of almost any shape on an object made of virtually any material, using a new approach to fabrication and transfer of nanowire electronics developed by Stanford researchers. Stanford researchers have developed a new method of attaching nanowire electronics to the surface of virtually …
People often talk about Business as usual (BAU) which is to expect the world say in energy to be a replay of what the past 20-50 years has been. BAU is usually focused on the United States, Europe and the rest of the OECD (the traditionally developed countries). However, we can currently expect very little …
Luminescence from solutions of small semiconductor clusters (‘quantum dots’) of different sizes. By simply changing the size of the dots, we can change the colour of light they absorb or give out – so we can match the dots to the part of the solar spectrum we want to collect.

Nanoletters – Graphene Spintronic Devices with Molecular Nanomagnets The possibility to graft nano-objects directly on its surface makes graphene particularly appealing for device and sensing applications. Here we report the design and the realization of a novel device made by a graphene nanoconstriction decorated with TbPc2 magnetic molecules (Pc = phthalocyananine), to electrically detect the …
Some academics have written an 8 page paper about exascale computing and the end of Moore’s law. Marc Snir et al try to make the case that * We will hit the end of Moore’s law in mid-2020 with 7 nanometer lithography chips. * spintronics may not be ready in time they call for * …
IEEE Spectrum January 2010 report on winners and loser, aimed one loser arrow that might have missed its mark. Building a practical quantum computer has proved hard. Really hard. Despite efforts by some of the world’s top physicists and engineers and the likes of IBM, HP, and NEC, progress has been slow. Ask the experts …
Adaptive Vehicle Make (AVM) is a portfolio of programs overseen by the Defense Advanced Research Projects Agency (DARPA). The three primary programs are META, Instant Foundry Adaptive through Bits (iFAB) and Fast Adaptable Next-Generation Ground Combat Vehicle (FANG GCV) programs. DARPA Disruptive Manufacturing Technologies page Adaptive Vehicle Make page DARPA has proposed 2012 budget which …
Magnetic studies of ultrathin slabs of copper-oxide materials reveal that at very low temperatures, the thinnest, isolated layers lose their long-range magnetic order and instead behave like a “quantum spin liquid” — a state of matter where the orientations of electron spins fluctuate wildly. This unexpected discovery by scientists at the U.S. Department of Energy’s …
Flash Bainite is the Strongest, Most Ductile, Lean Alloyed, Readily Weldable, Least Expensive Ultra Strength METAL known to man. A50 tensile ranges from 1100 to 2080MPa (160-302ksi) with 8 to 9% elongation. Total elongation up to 10-11% is not uncommon. Flash 4130 at 1900MPa and 9% elongation exceeds titanium-6Al-4V’s strength to weight ratio making it …
George Dvorsky at Sentient Developments talks about basic transhumanism. Transhumanism is something that’s applied in the here-and-now; it’s a recognition of the radical present and all that it has to offer. This is how the modern transhumanist can best unlock her biological potential. In terms of specifics, these choices include the Paleolithic diet (also called …
a, Scanning electron micrograph (SEM) of a device (qubit and SQUID shown) with identical design parameters as the one measured during this work [1]. b, Schematic. Qubit loop (shaded) and galvanically coupled read-out SQUID. The crosses are Josephson junctions; R, bias resistors; C, shunt capacitances; L, inductances.
