Trapping carbon dioxide in an icy age
A fish on the ocean floor off California gazes at a sight no human has seen first-hand: a modified Raman spectrometer gathering data on a carbon dioxide sample. Jill Pasteris, Ph.D., Washington University professor of earth and planetary sciences, heads a Washington University group collaborating with researchers at the Monterey Bay Area Research Institute (MBARI) to determine the feasibility of storing the greenhouse gas carbon dioxide on the ocean floor. The Raman spectrometer is the first-ever deployed on the ocean floor.

In collaboration with oceanographers from the Monterey Bay Aquarium Research Institute (MBARI), a team of geologists at Washington University in St. Louis is using a rare instrument on the ocean floor just west of California. One of their earliest projects was to see if its possible to capture carbon dioxide from the atmosphere and store it on the ocean floor. The research is supported by the Department of Energy.
The geologists, headed by Jill Pasteris, Ph.D., professor of earth and planetary sciences in Arts & Sciences, and their MBARI colleagues are the first to deploy a Raman spectrometer on the ocean floor. The instrument combines a portable focusing lens with a potent laser to examine minerals, gases and liquids - even seawater itself. Pasteris group and their MBARI colleagues are using Raman spectroscopy to see what carbon dioxide in either a pure liquid or a complex solid phase will do on the sea floor. They also are examining the feasibility of synthetically trapping carbon dioxide in solids called clathrate hydrates, ice-like solids that form a cage around gas molecules, such as methane, trapping them and storing them. Such solids occur naturally on the ocean floor. The hope is that someday carbon dioxide can be trapped in a similar way.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
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...
