By examining volcanic rocks retrieved from deep in the ocean, scientists have found they can estimate the carbon dioxide stored beneath much of the earths surface – a development that could enhance understanding of how volcanoes affect climate. The research by University of Florida scientists and others will be reported this week in the journal Nature.
Scientists examined chunks of basalt, a type of volcanic rock formed when lava cools, from 12,000 feet below the Pacific along a massive geographical formation called the midocean ridge. The scientists discovered in these basalts traces of carbon dioxide and other compounds that originated deep within the Earths mantle, the source of most volcanic activity. Because compounds from this inaccessible region had never been found so well preserved, the rocks gave scientists a rare peek at what the mantle consists of – and what it might spew into the atmosphere through volcanoes.
"Most lava erupts at the surface and has lost its gases. From a geochemists point of view, you need to know what the composition of the mantle really is," said Mike Perfit, a UF geology professor and co-author of the Nature paper. "This kind of data might be useful in talking about the contribution of the mantle to the atmosphere and hydrosphere and how those concentrations might affect the climate."

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
