Wed 27 Jan 2016. Physicists develop a cooling system for the processors of the future. Researchers have found a solution to the problem of the overheating of active plasmonic components for high-speed data transfer in the optoelectronic microprocessors that are tens of thousands of times faster than the microprocessors currently in use today. It was demonstrated how to efficiently cool optoelectronic chips using industry-standard heatsinks despite the high heat generation in active plasmonic components. Based on the results of numerical simulations, it was concluded that if an optoelectronic chip with active plasmonic waveguides is placed in air, its temperature will increase by several hundred degrees Celsius, which will cause the device to malfunction. Multi-layered thermal interfaces of nano- and micrometer thickness, combined with simple cooling systems, can reduce the temperature of the chip from several hundred degrees to approximately ten degrees with respect to the ambient temperature. This opens the prospects for the implementation of high-performance optoelectronic microprocessors in a wide range of applications, including supercomputers and compact electronic devices. More

Mon 21 Dec 2015. A new course for extracting uranium from seawater. An ultra-high-resolution technique used for the first time to study polymer fibers that trap uranium in seawater may cause researchers to rethink the best methods to harvest this potential fuel for nuclear reactors. Despite the low concentration of uranium and the presence of many other metals extracted from seawater, reserachers were able to investigate the local atomic environment around uranium and better understand how it is bound by the polymer fibers using X-ray Absorption Fine Structure (XAFS) spectroscopy.

Mon 14 Dec 2015. Nuclear Waste Storage Sites in Rock Salt May be More Vulnerable Than Previously Thought. rock salt, used by Germany and the United States as a subsurface container for radioactive waste, might not be as impermeable as thought or as capable of isolating nuclear waste from groundwater in the event that a capsule or storage vessel failed. A recent research has used field testing and 3-D micro-CT imaging of laboratory experiments to show that rock salt can become permeable. This new finding has implications for oil and gas operations, and, most notably, nuclear waste storage. More

Tue 3 Nov 2015. Chemical complexity promises improved structural alloys for next-gen nuclear energy. Designing alloys to withstand extreme environments is a fundamental challenge for materials scientists. Energy from radiation can create imperfections in alloys, so researchers are investigating ways to design structural materials that develop fewer, smaller flaws under irradiation. Advanced structural materials that can withstand radiation are a critical national need for nuclear reactor applications. Next-generation reactors will be expected to serve over longer lifetimes and withstand higher irradiation levels. More
