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.

High-precision measurement of the g-factor eleven times more precise than before / Results indicate a strong similarity between protons and antiprotons
The magnetic moment of an individual proton is inconceivably small, but can still be quantified. The basis for undertaking this measurement was laid over ten...
Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that...
The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
