As one example, there may be a plurality of holes formed in the touch surface. Suction may be applied to a first hole of the plurality of holes and pressurized air may be emitted from a second hole of the plurality of holes.FUKUMOTO, MasaakiHACHISU, Taku...
Attractive and repulsive tip-sample interaction regimes of a force microscope operated with an amplitude modulation feedback were investigated as a function of tip-sample separation, free amplitude, and sample properties. In the attractive regime, a net attractive force dominates the amplitude reduction...
(via the determination of minima observed inFvs.dcurves as the tip is first brought into contact and then retracted from the surface). Note that due to the “snapping into contact” of the cantilever upon approach, static force spectroscopy measurements will not yield information on attractive ...
When the dominant interaction is either attractive or repulsive, the magnitude of the phase shift (Δφ) increases with decreasing set-point ratio rsp=Asp/A0, and the Δφ-vs.-rsp plots are nearly independent of the drive amplitude, A0. These observations indicate that the cantilever vibration...
What actually occurs as two molecules approach is that the van der Waals attractive forces increase to a maximum, then decrease and become repulsive (Figure 15.8B). The van der Waals radius is defined as one half the distance between two equivalent atoms at the point of the energy minimum (...
Calling the repulsive force as blackbody radiation and the attractive force as blackbody force, scientists showed that this blackbody force (pull) can be stronger than the blackbody radiation (push). And for tiny particles, this type of force can even be stronger than the pull of gravity. ...

representation of the changes in resonance frequency (solid black curve) of the AFM cantilever due to the magnetic force gradient; in this case, the frequency shift (dashed red curve) reflects an attractive force gradient, and the frequency shift (dashed blue curve) reflects an repulsive force ...
In the image recorded with the magnetized tip (Fig. 4b) a slight negative contrast was detected in cor- respondence of the biggest NP, indicating a weak attractive tip-NP interaction. Conversely, a positive contrast was detected in correspondence of smaller NPs, indicating a repulsive tip-...
