DNA Nucleosides in a Tunneling Gap and Carbon Nanotube Nanopore DNA Reading Could Speed DNA Sequencing 1000 Times

Tunneling measurements with functionalized electrodes. (A) A gold probe and a gold substrate are functionalized with a monolayer of 4-mercaptobenzoic acid, and the size of the gap between two electrodes maintained under servo control at a value such that the two monolayers do not interact with one another, resulting in a tunnel current signal that …

Bringing Quantum entanglement from 4 Degrees Kelvin up to 50 Degrees

Arxiv- (11 page pdf) Bringing entanglement to the high temperature limit We show the existence of an entangled nonequilibrium state at very high temperatures when two linearly coupled harmonic oscillators are parametrically driven and dissipate into two independent heat baths. This result has a twofold meaning: first, it fundamentally shifts the classical-quantum border to temperatures …

Possibly Revolutionary Dry Contact Printing of Carbon Nanotubes Patterns to Any Surface

Rice University has developed dry printing of nanotube patterns to any surface which could revolutionize microelectronics and more. Rice graduate student Cary Pint has come up with a way to transfer patterns of strongly aligned, single-walled carbon nanotubes (SWNTs) from a substrate to another surface – any surface – in a matter of minutes. The …

Compact Proton Beam Accelerators and Handheld Fusion Reactors

Previously this site had reported on the DARPA project to create chip scale high energy atomic beams as a path to commercial nuclear fusion. There is a DARPA budget document with a bit more description that what was previously referenced. The Chip-Scale High Energy Atomic Beams program will develop chip-scale high-energy atomic beam technology by …

UK Develops Cheaper Recovery of Uranium from Radioactive Water

Researchers at the UK’s Birmingham University have recovered uranium from the radioactive waters of uranium mines using bacteria and inositol phosphate, a chemical parallel of a cheap waste material from plants. The same technology can also be used to clean up nuclear waste. Professor Lynne Macaskie Sunday presented the group’s work to the Society for …
