It is possible to build your own Watson Jr. question-answering system, something less fancy, less sophisticated, scaled-down for personal use or business workgroup usage As with any Do-It-Yourself (DIY) project, I am not responsible if you are not happy with your Watson Jr. I am basing the approach on what I read from publicly available …
Chemistry of Materials – Self-Templating of Metal-Driven Supramolecular Self-Assembly: A General Approach toward 1D Inorganic Nanotubes The rational design of one-dimensional (1D) inorganic nanomaterials directed by self-assembled soft matters is one of the most attractive subjects in modern chemistry. In this work, the self-templating approach based on metal−cholate supramolecular self-assemblies is reported, which is distinct …
New research from the University of Pennsylvania demonstrates a more consistent and cost-effective method for making graphene Other methods make expensive custom copper sheets in an effort to get them as smooth as possible; defects in the surface cause the graphene to accumulate in unpredictable ways. Instead, Johnson’s group “electropolished” their copper foil, a common …
The US has important strategic interests in Bahrain, including the US Navy’s Fifth Fleet – patrolling oil shipping lanes, keeping an eye on Iran, and involved with the war in Afghanistan. But US officials also worry about Bahrain’s violent response to pro-democracy demonstrators. With about 30 ships (including two aircraft carriers) the Fifth Fleet patrols …
1. With development of large-scale reactors in the United States slowed by constrained debt capital markets, the absence of climate legislation, low gas prices and flagging power demand, talk in the nuclear industry has shifted to next-generation reactors that are smaller, less capital-intensive and therefore more flexible. These small and modular reactors (SMRs), generally 300 …
Capacitor effect for magnetic monopoles in spin ice. The application of a magnetic potential adds new magnetic monopoles to a crystal of spin ice which then spring apart and store magnetricity. Researchers at the LCN have created a purely magnetic version of one of the basic effects of electronics – the storage and release of …
Columbia University – At its core the Internet has “waterfalls of bandwidth,” Bergman says, and should be able to handle the traffic. But traffic jams start as the volumes of information travel through narrower channels controlled by various Internet service providers. The current optical fibers can’t recognize what kind of data is coming through; when …
Top row: An atomic image of strontium titanate with one single rare-earth (R) -oxygen layer in the middle. The structure model is shown in the middle, where red is oxygen, green is strontium, blue is titanium and yellow is the rare-earth element. The RO layer at the interface can donate electrons to neighboring atomic layers. …
Financial times- Saudi Arabia is considering two options to supply oil to make up for the shortfall from Libya The first would be to boost production and send more crude through the east-west pipeline, linking the country’s largest oilfields in Eastern province with the Red Sea port of Yanbu, for shipment to Europe. Another possibility …
At MIT, a host of researchers are exploring how to reinvent chip architecture from the ground up, to ensure that adding more cores makes chips perform better, not worse. One way to improve communication between cores, which the Angstrom project is investigating, is optical communication — using light instead of electricity to move data. Though …
Arvid Guterstam conducting an experiment. Brain scientists at Karolinska Institutet (sweden) have now shown that it is possible to make healthy volunteers experience having three arms at the same time. A related study at Karolinska is said to have resulted in people perceiving that their physical selves were located not in their own bodies, but …
