Mon 24 Aug 2015. A new Power grid forecasting tool (PMI) that increases the accuracy of forecasting future electricity needs by up to 50%, and may also have the potential to save millions in wasted energy costs, has been developed. Accurately forecasting future electricity needs can be difficult due to sudden weather changes or other variables impacting projections minute by minute. The Power Model Integrator - PMI has been designed to assist with addressing costly errors that can lead to serious impacts, from blackouts to high market costs. Performance of the tool was tested against five commonly used forecasting models processing a year’s worth of historical power system data. Fluctuations in energy demand throughout the day, season and year along with weather events and increased use of intermittent renewable energy from the sun and wind all contribute to forecasting errors. Miscalculations can be costly, put stress on power generators and lead to instabilities in the power system. More

Mon 17 Aug 2015. Sol-gel Capacitor Dielectric Offers Record-high Energy Storage. Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. If the material can be scaled up from laboratory samples, devices made from it could surpass traditional electrolytic capacitors for applications in electromagnetic propulsion, electric vehicles and defibrillators. Capacitors often complement batteries in these applications because they can provide large amounts of current quickly. More

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.
