Nanoimprinting lithography improved

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 provide radiation shielding and more

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 …

1000 times more useful molecules for nuclear magnetic resonance quantum computing

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. …

Nanostructures near 10 nanometers are created

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. …
