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.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
