Laser-ultrasound decodes the mechanics of nanoporous silicon.
Nanostructuring of supplies results in fully new, typically stunning properties; this makes them extremely attention-grabbing for brand new fields of software and applied sciences. Nonetheless, whether or not these supplies may be processed into strong parts and thus discover their means into functions relies upon very a lot on their mechanical properties. These are often significantly tough to find out with out altering them by means of the measuring course of and even destroying the supplies. A German-French analysis group led by Patrick Huber (DESY and TU Hamburg) has now developed a non-contact
