Multiphoton lithography (MPL) is a technique that uses ultra-short laser pulses to create complex three-dimensional (3D) structures at the micro- and nanoscale. It is based on the principle of multiphoton absorption (MPA), ...
The potential of an ultrafast form of transmission electron microscopy to measure sound waves in nanostructures has been demonstrated by three RIKEN physicists. This could help realize a high-resolution imaging method that ...
