Thu 23 Jul 2015. Boosting Wireless Power Transfer with Magnetic Field Enhancement. Wireless power transfer works by having a transmitter coil generate a magnetic field; a receiver coil then draws energy from that magnetic field. One of the major roadblocks for development of marketable wireless power transfer technologies is achieving high efficiency. New research shows that passing wireless power transfer through a magnetic resonance field enhancer (MRFE) – which can be as simple as a copper loop – can boost the transfer efficiency by at least 100 percent as compared to transferring through air alone. MRFE use could potentially boost transfer efficiency by as much as 5,000 percent in some systems. By placing the MRFE between the transmitter and the receiver (without touching either) as an intermediate material, the researchers were able to significantly enhance the magnetic field, increasing its efficiency.

Sat 13 June. Hybrid scanner combines five molecular imaging technologies. Scientists are taking medical imaging research and drug discovery to a new level by developing a molecular imaging system that combines several advanced technologies for all-in-one imaging of both tissue models and live subjects. Each imaging technology has its own strengths. Direct positron imaging is a nuclear medicine technique that allows researchers to gain physiological information from radiolabeled imaging agents that bind to targets in the body, which are then imaged with a specialized detector. The hybrid system applies both conventional and hyperpolarized MRI. The former is ideal for soft-tissue contrast, and the latter has extremely fine imaging resolution due to a revolution in the technology called dynamic nuclear spin polarization (DNSP), which is used to track minute biochemistry in the body -- such as the transition of the naturally occurring chemical pyruvate to lactate.

Mon 18 May 2015. First Proton Collisions at World's Largest Science Experiment Should Start in Early June. The LHC at CERN in Geneva was restarted last Aplril for its second three-year run after a two-year pause to upgrade the machine to operate at higher energies. At higher energy, physicists worldwide expect to see new discoveries about the laws that govern our natural universe. The world's largest particle accelerator, the Large Hadron Collider made headlines when its global collaboration of thousands of scientists in 2012 observed a new fundamental particle, the Higgs boson. After that, the collider was paused for the extensive upgrade. Much more powerful than before, as part of Run 2 physicists on the Large Hadron Collider's experiments are analyzing new proton collision data to unravel the structure of the Higgs. More

Wed 25 Mar 2015. Researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key information for engineering the electronics of tomorrow. In the race to miniaturize electronic components, researchers are challenged with a major problem: the smaller or the faster your device, the more challenging it is to cool it down. One solution to improve the cooling is to use materials with very high thermal conductivity, such as graphene, to quickly dissipate heat and thereby cool down the circuits. Researchers have demonstrated that heat propagates in the form of a wave, just like sound in air. This was up to now a very obscure phenomenon observed in few cases at temperatures close to the absolute zero.Their simulations provide a valuable tool for researchers studying graphene, whether to cool down circuits at the nanoscale, or to replace silicon in tomorrow's electronics.
