Rapid urbanization in southeastern China in the past 25 years is responsible for an estimated warming rate much larger than previous estimates for other periods and locations, according to a new study funded by NASA.
Researchers led by the Georgia Institute of Technology report that the mean surface temperature in the region has risen 0.09 degrees Fahrenheit (0.05 degrees Celsius) per decade since 1979. Also, nighttime low temperatures have risen much faster than the daytime high temperatures. The average reduction of the day-to-night temperature range was 0.24 degrees F (0.132 degrees C) per decade. Their findings will appear in the June 29 print edition of the journal Proceedings of the National Academy of Sciences.
To estimate the temperature changes due to urbanization, researchers used a new approach that integrated meteorological station observations, model-assimilated temperature predictions, satellite-measured greenness and Chinas census data. The modeling data -- provided by the National Oceanic and Atmospheric Administrations Centers for Environmental Prediction and the U.S. Department of Energy -- is considered more accurate than previous information because of its improvements in accounting for temperature range differences affected by cloud cover and soil moisture, the researchers note.

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...

The trend-forward world of display technology relies on innovative materials and novel approaches to steadily advance the visual experience, for example through higher pixel densities, better contrast, larger formats or user-friendler design. Fraunhofer ISC’s newly developed materials for optics and electronics now broaden the application potential of next generation displays. Learn about lower cost-effective wet-chemical printing procedures and the new materials at the Fraunhofer ISC booth # 1021 in North Hall D during the SID International Symposium on Information Display held from 22 to 27 May 2016 at San Francisco’s Moscone Center.
