Sea surface temperatures play a big role in keeping a tropical cyclone alive. They need warm seas of at least 300 Kelvin (80 Fahrenheit/26.8 Celsius) to maintain strength. NASA's Aqua satellite revealed that those conditions were not met where Chris is located in the Atlantic Ocean.
NASA's Aqua satellite passed over Post-Tropical Storm Chris on June 22 at 12:47 a.m. EDT. The infrared data from the AIRS instrument onboard Aqua indicated the storm is in waters that are too cool to maintain its strength. The waters are near 290 Kelvin (62F/16.8C). Credit: NASA/JPL, Ed Olsen
When NASA's Aqua satellite passed over Chris at 0447 UTC (12:47 a.m. EDT) today, June 22, the Atmospheric Infrared Sounder (AIRS) instrument captured a new infrared image of Chris' clouds and surrounding sea surface temperatures. The sea surface temperatures to the south of Chris are at least 300 Kelvin (80 Fahrenheit/26.8 Celsius) and warmer. In the area where Chris is located, AIRS revealed that sea surface temperatures are closer to 290 Kelvin (62 Fahrenheit/16.8 Celsius).
At 11 a.m. EDT on June 22, Chris was now classified as a post-tropical storm with maximum sustained winds near 45 mph (75 kmh). Chris was far to the north near 44.6 North and 46.9 West, about 335 miles (535 km) east-southeast of Cape Race, Newfoundland, Canada. Chris was moving to the west-southwest near 16 mph (kmh), and is expected to slow and turn southward. Chris' minimum central pressure is 990 millibars.
According to the National Hurricane Center, Chris "should merge with another extratropical low on Saturday [June 23]" in the north Atlantic Ocean.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
