Graduate student Jianhui Shang holds two pans stamped from automotive grade aluminum. The pan on the right was stamped using traditional techniques. The one on the left was stamped using the same equipment, but employing Daehn’s electromagnetic bump forming technique.
A process developed at Ohio State University for shaping metal parts using magnetism has reached a new milestone -- one that may cut manufacturing costs and help preserve the environment.
The process could also expand manufacturers’ choice of available metals, and enable the use of aluminum parts in lighter, fuel-efficient automobiles.
Glenn S. Daehn, professor of materials science and engineering, and his colleagues pioneered hybrid electromagnetic metal forming in 1999, while collaborating with the “Big Three” automakers. With this process, a traditional tool and die stamps the general shape of a part out of sheet metal. Afterward, a magnetic field pushes at specific locations of the sheet metal to form fine details or complex shapes.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
