Purdue professor solves 140-year fluid mechanics enigma
West Lafayette IN (SPX) Oct 08, 2015 -
A Purdue University researcher has solved a 140-year-old enigma in fluid mechanics: Why does a simple formula describe the seemingly complex physics for the behavior of elliptical particles moving through fluid?
The findings have potential implications for research and industry because ellipsoid nanoparticles are encountered in various applications including those involving pharmaceuticals ...

Caution: Shrinks when warm
Storrs CT (SPX) Oct 09, 2015 -
Most materials swell when they warm, and shrink when they cool. But UConn physicist Jason Hancock has been investigating a substance that responds in reverse: it shrinks when it warms. Although thermal expansion, and the cracking and warping that often result, are an everyday occurrence - in buildings, bridges, electronics, and almost anything else exposed to wide temperature swings - physicists ...

Nanoscale photodetector could boost capacity of photonic circuits
Washington DC (SPX) Oct 07, 2015 -
Photonic circuits, which use light to transmit signals, are markedly faster than electronic circuits. Unfortunately, they're also bigger. It's difficult to localize visible light below its diffraction limit, about 200-300 nanometers, and as components in electronic semiconductors have shrunk to the nanometer scale, the photonic circuit size limitation has given electronic circuits a significant ...

Liquid cooling moves onto the chip for denser electronics
Atlanta GA (SPX) Oct 07, 2015 -
Using microfluidic passages cut directly into the backsides of production field-programmable gate array (FPGA) devices, Georgia Institute of Technology researchers are putting liquid cooling right where it's needed the most - a few hundred microns away from where the transistors are operating.
Combined with connection technology that operates through structures in the cooling passages, the ...

Poland seeks missiles for its MiG-29 fighters
Warsaw, Poland (UPI) Oct 9, 2015 -
Poland has reportedly begun the process to obtain 40 radar-guided R-27R1 missiles, the main armament on Poland 's Soviet-era MiG-29 fighters.
Polish news site Defence24 says the acquisition process is being conducted by the Ministry of National Defense's Armament Inspectorate.
The missiles obtained should be guaranteed by the manufacturer to be usable for at least 96 months if de ...

Airbus DS ready to start testing exoplanet tracker CHEOPS
Paris, France (SPX) Oct 14, 2015 -
Airbus Defence and Space has finished building the structural model for ESA's CHEOPS (CHaracterising ExOPlanet Satellite), Europe's first mission to search for exoplanetary transits by performing ultra-high precision photometry on bright stars already known to host planets.
Airbus Defence and Space, as prime contractor of CHEOPS, is preparing the first spacecraft test campaign in Spain. Th ...
