C. Diamantini from NiPS lab visits the Physics of Information Group in Lisbon

Cristina Diamantini, form NiPS Laboratory, University of Perugia, is visiting the Physics of Information Group in Lisbon. She will present the seminar: Generalized Landauer Bound as Universal Thermodynamic Entropy in Continuous Phase Transitions Date & time: 24/03/2015 at 10:00. Location: Seminar Room (2.8.3), Physics Department, Instituto Superior Técnico, Lisbon. Abstract: The classic Landauer bound can be lowered when erasure errors are permitted. Here we point out that continuous phase transitions characterized by an order parameter can also be viewed as information erasure by...

TU-Delft: NEMS switches as gas sensors

Cantilevers play an important role as linear transducers in nanoscience, with nanomechanical detection of mass and stress as a clear example. We performed gas sensing experiments with a standard functionalized cantilever driven strongly into the regime of nonlinear oscillations. We compared the cantilever response to the selective adsorption of ethanol vapour in the nonlinear regime, to the ones obtained in the conventional linear static and dynamic sensing modes. In the nonlinearly driven cantilever, the adsorption and desorption-induced frequency shifts were enhanced by over a factor of...
