Magnetic Graphene could lead to multifunction devices
http://ift.tt/hZ0OVi
A team of physicists at the University of California, Riverside has found an ingenious way to induce magnetism in graphene while also preserving graphene’s electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator – an electrical insulator with magnetic properties.
“The magnetic graphene acquires new electronic properties so that new quantum phenomena can arise. These properties can lead to new electronic devices that are more robust and multi-functional.”
The finding has the potential to increase graphene’s use in computers, as in computer chips that use electronic spin to store data.
The magnetic insulator Shi and his team used was yttrium iron garnet grown by laser molecular beam epitaxy in his lab. The researchers placed a single-layer graphene sheet on an atomically smooth layer of yttrium iron garnet. They found that yttrium iron garnet magnetized the graphene sheet. In other words, graphene simply borrows the magnetic properties from yttrium iron garnet.

(b) Optical image (without top gate) and (d) schematic drawing (with top gate) of the devices after transferred to YIG/GGG substrate (false color). (c) Room temperature Raman spectra of graphene/YIG (purple), graphene/SiO2 (red), and YIG/GGG substrate only (blue).

DARPA developing code for drone wolf pack teams of six or more
http://ift.tt/hZ0OVi
The U.S. military’s investments in unmanned aircraft systems (UAS) have proven invaluable for missions from intelligence, surveillance and reconnaissance (ISR) to tactical strike. Most of the current systems, however, require constant control by a dedicated pilot and sensor operator as well as a large number of analysts, all via telemetry. These requirements severely limit the scalability and cost-effectiveness of UAS operations and pose operational challenges in dynamic, long-distance engagements with highly mobile targets in contested electromagnetic environments.
DARPA’s Collaborative Operations in Denied Environment (CODE) program aims to overcome these challenges by developing algorithms and software that would extend the mission capabilities of existing unmanned aircraft well beyond the current state-of-the-art, with the goal of improving U.S. forces’ ability to conduct operations in denied or contested airspace. CODE researchers seek to create a modular software architecture that is resilient to bandwidth limitations and communications disruptions, yet compatible with existing standards and capable of affordable retrofit into existing platforms.

CODE would enable mixed teams of unmanned aircraft to find targets and engage them as appropriate under established rules of engagement, leverage nearby CODE-enabled systems with minimal supervision, and adapt to situations due to attrition of friendly forces or the emergence of unanticipated threats—all under the command of a single human mission supervisor. CODE envisions improvements that would help transform UAS operations from requiring multiple people to operate a single UAS to having one person able to oversee six or more unmanned vehicles simultaneously
