Nanoimprinting lithography (NIL) is a simple pattern transfer process that is emerging as an alternative nanopatterning technology to traditional photolithography. NIL already has been applied in various fields such as biological nanodevices, nanophotonic devices, organic electronics, and the patterning of magnetic materials. Researchers at Berkeley have taken this process one step further by demonstrating that …
Boron nanotubes can provide strong, light weight, cost effective radiation shielding for space and fusion reactors Compared to CNTs, boron nanotubes have some better properties such as high chemical stability, high resistance to oxidation at high temperatures and are a stable wide band-gap semiconductor. Because of these properties, they can be used for applications at …
A new technique for dynamic nuclear polarization that is more than twice as effective as previous versions. “Our N@C60 fullerene molecules have a nitrogen atom in their very centre with a nuclear spin and an electron spin. We want to use both spins to store quantum information as they can each point up or down. …

Steve Howe and the Center for Space Nuclear Research (CSNR) suggests using a Nerva like nuclear rocket stage to go from orbit to the moon It would enable 40% more cargo to be delivered on each trip. Previous work, including a NASA study, have suggested that it would cost only $2.5 to $3 billion to …
The University of Pennsylvania scientists used transmission electron beam ablation lithography to “carve” nanostructures from thin sheets of gold, silver, aluminum and other metals. The researchers said TEBAL provides a more dependable method for producing quality versions of such microscopic devices, while also permitting simultaneous, real-time atomic imaging of the devices as they are made. …
New Scientist reports a single hydrogen atom has been snipped off a molecule and then added back on again, marking the first time a single chemical bond has been broken and reforged in a controlled, reversible way. Update: The work was done at 4.7 degrees kelvin Update 2: some points from Robert Freitas This is …
The cheapest launch for a moderate sized payload is the Dnepr rocket. It costs $10 million and can launch 4500 kg to LEO. $2222/kg.

Cree, Inc. (Nasdaq:CREE), a market leader in LED solid-state lighting components, today announced commercial availability of XLamp(r) LEDs with minimum luminous flux of 100 lumens at 350 mA. XLamp LEDs are the first LEDs to be available in volume with this level of performance. This advance sets a new standard in lighting-class LED brightness and …
This pdf discusses a recent presentation by Geordie Rose, CTO of Dwave Systems The main thing is that Dwave believes that they are still on track to release a commercial system May, 2008 that will be one hundred times faster for certain business relevant problems. This would probably be the 512 qubit machine. The 1024 …
