Technology Review – Cars that park themselves and automatically convoy with other cars could reduce congestion and emissions. The biggest benefits will come with fully automated cars. Cars that park themselves—a trick GM has demonstrated with its EN-V concept vehicle—could save fuel by eliminating the need for drivers to circle the block waiting for a …
The Journal of Physical Chemistry C- Fe2O3-Graphene Rice-on-Sheet Nanocomposite for High and Fast Lithium Ion Storage Graphene nanosheet (GNS)-supported Fe2O3 nanorice and nanoparticles were synthesized by a microwave-assisted hydrothermal technique. The Fe2O3-GNS rice-on-sheet composite showed a better suitability as an anode material for Li-ion batteries. It exhibited a very large reversible capacity of 1184 mAh/g …
Today Anwar al-Awlaki was killed by a U.S. drone strike. Awlaki, identified by U.S. intelligence as “chief of external operations” for al Qaeda’s Yemen branch and a Web-savvy propagandist for the Islamist cause, was killed in an attack by missiles fired from multiple CIA drones in a remote Yemeni town. The US is continuing to …
The 71st Carnival of Nuclear Energy is up at NEI Nuclear notes Atomic Insights looks at how oil and gas companies benefit from any backlash against nuclear power. In the six months since the great northeast Japan earthquake and tsunami, the world market price of Liquified Natural Gas (LNG) has increased by 33% and the …
Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away seemed to show up a tiny fraction of a second early. “We tried to find all possible explanations for this,” said report author Antonio Ereditato of the Opera collaboration. Opera Collaboration website The OPERA particle detector may have spotted neutrinos traveling …
Researchers under ETH-Zurich professor Colombo Bolognesi are working on a new gallium nitride transistor technology using silicon(110) as a substrate. As the new combination of materials has many advantages, gallium nitride is poised to conquer the electronics market and help power the green revolution. For the first time, researchers from CNRS France and ETH Zurich …
Physics World – A tiny bubble of graphene could be used to make an optical lens with an adjustable focal length. That is the claim of physicists in the UK, who have shown that the curvature of such bubbles can be controlled by applying an external voltage. Devices based on the discovery could find use …
In recent years, some physicists have found some cuprates in which the transition to zero resistance occurs at a lower temperature than the Meisner effect. So at low temperatures, the cuprate acts like a normal superconductor. As the temperature rises, it goes through a first transition and loses its zero resistance while maintaining the Meisner …
Dr. Richard Nebel used to be the lead researcher at EMC2 Fusion. EMC2 Fusion is funded by the Navy to develop inertial electrostatic fusion. The EMC2 fusion processed were developed by Dr Bussard (Bussard Ramjet and a lot of other work). Dr Nebel is now at Tibbar Technologies. (H/T Talk polywell Electrostatic Mode Locking and …
The Hamilton project has shown that US productivity growth has stalled since about 1973. The underperformed of 2% per year has resulted in the US being half as rich per capita as it could have been if we had maintained the 1948-1973 trend I was on the World Transformed interview series and discussed existential risks …
Neural implants have the potential to treat disorders and diseases that typically require long-term treatment, such as blindness, deafness, epilepsy, spinal cord injury, and Alzheimer’s and Parkinson’s. However, implantable devices have been problematic in clinical applications because of bodily reactions that limit device functioning time. Graphene neural implants could be made to last longer (perhaps …
