Anharmonicity in multifrequency atomic force microscopy
(2014-07)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
In multifrequency atomic force microscopy higher eigenmodes are externally excited to enhance resolution and contrast while simultaneously increasing the number of experimental
observables with the use of gentle forces. ...
Establishing nanoscale heterogeneity with nanoscale force measurements
(2015-08-13)
Article.
Accés obert
Article.
Accés obert
Establishing the presence or absence of nanoscale compositional heterogeneity with nanoscale resolution is becoming instrumental for the development of many fields of science. Force versus distance measurements and parameters ...
Forward backward asymmetries of lepton pairs in events with a large transverse momentum jet at hadron colliders
(2002-10)
Article.
Accés obert
Article.
Accés obert
We discuss forward-backward charge asymmetries for lepton-pair production in association with a large-transverse-momentum jet at hadron colliders. The lepton charge asymmetry relative to the jet direction AjFB gives a new ...
Deconstructing the governing dissipative phenomena in the nanoscale
(2014-01)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
An expression describing the controlling parameters involved in short range nanoscale dissipation is proposed and supported by simulations and experimental findings. The expression is deconstructed into the geometrical, ...
Wearing a single DNA molecule with an AFM tip
(2015-06)
Report de recerca.
Accés obert
Report de recerca.
Accés obert
While the fundamental limit on the resolution achieved in an atomic force microscope (AFM) is clearly related to the tip radius, the fact that the tip can creep and/or wear during an experiment is often ignored. This is ...
Periodicity in bimodal atomic force microscopy
(American Institute of Physics (AIP), 2015-07-28)
Article.
Accés obert
Article.
Accés obert
Periodicity is fundamental for quantification and the application of conservation principles of many important systems. Here, we discuss periodicity in the context of bimodal atomic force microscopy (AFM). The relationship ...
Advances in dynamic AFM: from nanoscale energy dissipation to material properties in the nanoscale
(2021-04-02)
Article.
Accés obert
Article.
Accés obert
Since the inception of the atomic force microscope (AFM), dynamic methods (dynamic atomic force microscopy) have been very fruitful by establishing methods to quantify dissipative and conservative forces in the nanoscale ...
Unlocking higher harmonics in atomic force microscopy with gentle interactions
(2014-03-11)
Article.
Accés obert
Article.
Accés obert
In dynamic atomic force microscopy, nanoscale properties are encoded in the higher harmonics. Nevertheless, when gentle interactions and minimal invasiveness are required, these harmonics are typically undetectable. Here, ...
