Cambridge Making Carbon Nanotubes Ribbons at Centimeter Lengths with 9 Gpa Strength, Which is Four Times Stronger than Kevlar

The Times UK reported claims that Alan Windle’s team at Cambridge University had created the world’s strongest ribbon. I finally tracked down specifics of this work. UPDATE: Details on hypersonic skyhooks/rotovators [orbital ropes] that would be enabled with these materials as well as lunar and Mars space elevators. Background on strength of materials, units of …

Stem cell blood supply breakthrough and other stem cell breakthroughs

Human blood have been grown from embryonic stem cells for the first time during research that promises to provide an almost limitless supply suitable for transfusion into any patient. This could lead to trials of the blood within two years, and ultimately to an alternative to donations that would transform medicine. If such blood was …

Carbon nanotubes as strong as theory and irradiation makes them stronger

True strength properties of carbon nanotubes measured and they match with theoretical predictions. Previous measurements came up a lot weaker than theory. Not only do the new measurements show that defect free carbon nanotubes are as strong as predicted but the an irradiation strategy can fix defects and provide cross links to help carbon nanotube …

Achieving a Mundane Technological Transhuman Singularity

Some people have criticized the technological Singularity and Transhumanism because of the upside being things that they do not believe can be achieved.Also, the primary technologies that are often described as enabling the Singularity and Transhumanism are Molecular Nanotechnology and greater than human intelligence general AI. There has been virtually no effort or money spent …

Dwave Systems has $17 million in added funding to make a quantum computer with thousands of qubits by the end of 2008

Dwave Systems closed a $17M financing round as of the end of January 2008. These funds will be used primarily to push the level of integration of our chips into the low thousands of qubits by the end of the year. In parallel with this central effort we will be working on running experiments on …

Silicon spintronics closer for cheap continuation of Moore’s law

From EEtimes, Naval Research Laboratory (NRL) scientists will next month describe a technique that would allow spintronics to be inserted into the standard silicon CMOS processes using ferromagnetic materials similar to those already used for magnetic random access memory. Our demonstration showed a 30 percent polarization of the injected electrons, which is not bad considering …
