Heat Create Nanostructured Metals

Authors: George Rajna

Scientists have developed a new approach for making metal-metal composites and porous metals with a 3-D interconnected "bicontinuous" structure in thin films at size scales ranging from tens of nanometers to microns. [27] A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators - resulting in leak-free machines that can stay operating longer. [26] Like watchmakers choosing superior materials to build a fine timepiece, physicists at the Centre for Quantum Technologies (CQT) at the National University of Singapore have singled out an atom that could allow them to build better atomic clocks.
