A group of researchers from Yale University and colleagues from the University of Georgia and Massachusetts Institute of Technology demonstrated a novel approach that allows ferrofluids to be pumped by magnetic fields alone. The approach could allow this material to be used in new generation of highly compact, integrated, quiet, and efficient liquid cooling schemes… »

After writing about ferrofluid sculptures and Stanford scientists that combined carbon nanotubes and paper, in this article we’re going to write about researchers at Purdue University who have created a magnetic ferropaper. The material is made by impregnating ordinary paper (even newsprint) with a mixture of mineral oil and “magnetic nanoparticles” of iron oxide. The… »
