    • Advances in dynamic AFM: from nanoscale energy dissipation to material properties in the nanoscale 

      Santos Hernández, Sergio; Gadelrab, Karim Raafat; Lai, Chia-Yun; Olukan, Tuza; Font Teixidó, Josep; Barcons Xixons, Víctor; Verdaguer Prats, Albert; Chiesa, Matteo (2021-04-02)
      Article
      Open Access
      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 ...
    • Establishing nanoscale heterogeneity with nanoscale force measurements 

      Chang, Yun-Hsiang, Yun-Hsiang; Olukan, Tuza; Lai, Chia-Yun; Santos, Sergio; Lin, Tze-Yu; Apostoleris, Harry; Font Teixidó, Josep; Barcons Xixons, Víctor; Chiesa, Matteo (2015-08-13)
      Article
      Open Access
      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 ...
    • Machine learning assisted multifrequency AFM: Force model prediction 

      Elsherbiny, Lamiaa; Santos, Sergio; Gadelrab, Karim Raafat; Olukan, Tuza; Font Teixidó, Josep; Barcons Xixons, Víctor; Chiesa, Matteo (American Institute of Physics (AIP), 2023-12-05)
      Article
      Open Access
      Multifrequency atomic force microscopy (AFM) enhances resolving power, provides extra contrast channels, and is equipped with a formalism to quantify material properties pixel by pixel. On the other hand, multifrequency ...
    • Probing power laws in multifrequency AFM 

      Santos, Sergio; Gadelrab, Karim Raafat; Olukan, Tuza; Font Teixidó, Josep; Barcons Xixons, Víctor; Chiesa, Matteo (2023-02-17)
      Article
      Open Access
      Quantification of conservative forces in multifrequency atomic force microscopy requires solving the general equations of the theory expressed in terms of the virials of interaction. Power law expressions are commonly ...
    • Quantification of van der Waals forces in bimodal and trimodal AFM 

      Santos, Sergio; Gadelrab, Karim Raafat; Elsherbiny, Lamiaa; Drexler, Xavier; Olukan, Tuza; Font Teixidó, Josep; Barcons Xixons, Víctor; Chiesa, Matteo (2023-05-28)
      Article
      Open Access
      The multifrequency formalism is generalized and exploited to quantify attractive forces, i.e., van der Waals interactions, with small amplitudes or gentle forces in bimodal and trimodal atomic force microscopy (AFM). The ...
