Effect of sliding friction in harmonic oscillators
Miguel V. Vitorino, Arthur Vieira, Mário S. Rodrigues
Sliding friction is ubiquitous in nature as are harmonic oscillators. However, when treating harmonic oscillators the effect of sliding friction is often neglected. Here, we propos…
Frequency dependent visco-elastic properties of a water nanomeniscus : an AFM study in Force Feedback Mode
Simon Carpentier, Mario S. Rodrigues, Luca Costa +2
Recently, using an Atomic Force Microscope and a single cantilever excited at different frequencies it was shown that water nanomeniscus can exhibit a transition in mechanical resp…
Proximity effect on hydrodynamic interaction between a sphere and a plane measured by Force Feedback Microscopy at different frequencies
Simon Carpentier, Mario S. Rodrigues, Elisabeth Charlaix +1
In this article, we measure the viscous damping and the associated stiffness of a liquid flow in sphere-plane geometry in a large frequency range. In this regime, the…
Out of equilibrium anomalous elastic response of a water nano-meniscus
Simon Carpentier, Mario S. Rodrigues, Luca Costa +3
We report the observation of a transition in the dynamical properties of water nano-menicus which dramatically change when probed at different time scales. Using a AFM mode that we…
Variable frequency characterization of interaction at nanoscale in linear dynamic AFM: an FFM primer
Simon Carpentier, Mario S. Rodrigues, Joël Chevrier
Using electrostatic coupling between an AFM tip and a metallic surface as a test interaction, we here present the measurement of the force between the tip and the surface, together…
Small amplitude Dynamic AFM: quantifying interactions with different tip detection and excitation schemes in presence of additional resonances
Luca Costa, Mario S Rodrigues
Quantifying the tip-sample interaction at the nanoscale in Amplitude Modulation mode AFM is challenging, especially when measuring in liquids. Here, we derive formulas for the tip-…
