Researchers at Purdue University have created a magnetic "ferropaper" that might be used to make low-cost "micromotors" for surgical instruments, tiny tweezers to study cells and miniature speakers.
The material is made by impregnating ordinary paper -- even newsprint -- with a mixture of mineral oil and "magnetic nanoparticles" of iron oxide. The nanoparticle-laden paper can then be moved using a magnetic field.
"Paper is a porous matrix, so you can load a lot of this material into it," said Babak Ziaie, a professor of electrical and computer engineering and biomedical engineering.
monochrom is an art-technology-philosophy group having its seat in Vienna and Zeta Draconis. monochrom is an unpeculiar mixture of proto-aesthetic fringe work, pop attitude, subcultural science, context hacking and political activism. Our mission is conducted everywhere, but first and foremost in culture-archeological digs into the seats (and pockets) of ideology and entertainment. monochrom has existed in this (and almost every other) form since 1993.
