Phononic crystals

Prof. Ned Thomas and colleagues have succeeded in creating a synthetic crystal that can very effectively control the transmission of heat — stopping it in its tracks and reflecting it back. This advance could lead to insulating materials that could block the escape of heat more effectively than…   more
