Experiment reveals new mysterious properties of sound waves
COLUMBUS, Ohio—Researchers at The Ohio State University have discovered how to control heat with a magnetic field. In the March 23 issue of the journal Nature Materials, they describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by 12 percent. The study is the first ever to prove that acoustic phonons—the elemental particles that transmit both heat and sound—have magnetic properties.
Phi Beta Iota: This is important — and should be connected to other endeavors (see below) that together suggest that a radical reduction of fossil fuel needs is on the horizon. Life is about design — smaller cities, more trains, more public transport — and innovation. Ohio State and its backers — including elements of the US defense community — merit the greatest praise for pursing this line of inquiry.
