The Deep Ultravi Laser microscope reveals diamond’s nanoscale transport behavior
Dissemination optical creates two DUV beams. It uses a 4F imaging system to interfere with the sample surface (diamond) to generate a microscopic sine -stringed profile. Credit: Stephen Barouss/Mulnane and Caputein Group Ultra Wade band gaps such as diamonds are promising for next -generation electronic devices, higher voltage, and higher frequencies, and operates at higher frequencies because of the large…

Storm Éowyn hits Ireland and UK, causing power outages and transport disruptions
Ireland and Scotland were put on high alert in the face of Storm Éowyn. Storm Éowyn struck Ireland, Northern Ireland and Scotland on Friday, causing havoc, leaving one person dead, hundreds of thousands of homes without power, planes grounded and schools closed, officials said. Millions of people in three countries were urged to shelter in place from the “devastating” storm…

New method estimates translatitudinal Atlantic freshwater transport
Freshwater transport is related to the stability of the Atlantic meridional overturning circulation. Credit: Zheng Huayi Researchers from the Institute of Atmospheric Physics, Chinese Academy of Sciences and Xiamen University have developed an indirect method to estimate Atlantic meridional freshwater transport (AMFT) at different latitudes. The study was published in Geophysical Research Letters. The oceans, which contain 97% of Earth’s…
