Thermal analysis reaches the nanoscale
Researchers in the US have developed a technique that can probe the thermo-mechanical properties of materials on the nanoscale. Until now, it was only possible to measure such properties on the scale of micrometres, which meant that many important details like phase transitions at surfaces and interfaces in heterogeneous materials were missed. The new method is based on heated atomic force microscopy and will be useful for studying temperature-related phenomena like glass transition temperatures that occur on very small length scales.
