Corrosion Study of AA2024-T3 by Scanning Kelvin Probe Force Microscopy and In Situ Atomic Force Microscopy Scratching [PDF]

, 1998
The localized corrosion of AA2024-T3, and the behavior of intermetallic particles in particular, were studied using different capabilities of the atomic force microscope (AFM). The role of intermetallic particles in determining the locations and rates of

Amplitude Dependence of Resonance Frequency and its Consequences for Scanning Probe Microscopy

Sensors, 2019
With recent advances in scanning probe microscopy (SPM), it is now routine to determine the atomic structure of surfaces and molecules while quantifying the local tip-sample interaction potentials. Such quantitative experiments using noncontact frequency

Imaging of atomic orbitals with the Atomic Force Microscope - experiments and simulations [PDF]

, 2000
Atomic force microscopy (AFM) is a mechanical profiling technique that allows to image surfaces with atomic resolution. Recent progress in reducing the noise of this technique has led to a resolution level where previously undetectable symmetries of the ...

Interaction imaging with amplitude-dependence force spectroscopy

, 2013
Knowledge of surface forces is the key to understanding a large number of processes in fields ranging from physics to material science and biology. The most common method to study surfaces is dynamic atomic force microscopy (AFM).

Phase imaging with intermodulation atomic force microscopy

, 2009
Intermodulation atomic force microscopy (IMAFM) is a dynamic mode of atomic force microscopy (AFM) with two-tone excitation. The oscillating AFM cantilever in close proximity to a surface experiences the nonlinear tip-sample force which mixes the drive ...

Polarization contrast in photon scanning tunnelling microscopy combined with atomic force microscopy [PDF]

Journal of Microscopy, 1995
SummaryPhoton scanning tunnelling microscopy combined with atomic force microscopy allows simultaneous acquisition and direct comparison of optical and topographical images, both with a lateral resolution of about 30 nm, far beyond the optical diffraction limit.

Atomic force microscopy combined with confocal laser scanning microscopy: A new look at cells [PDF]

Bioimaging, 1993
A stand-alone atomic force microscope (AFM) has been developed, which features a large scan area and which allows operation under liquid. This system was combined with a confocal laser scanning microscope (CLSM). Information about cell structures, obtained by CLSM, can be complemented with images of the cell surface obtained with the AFM.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Atomic Force Microscopy and Scanning Ion-Conductance Microscopy for Investigation of Biomechanical Characteristics of Neutrophils

Cells
Scanning probe microscopy (SPM) is a versatile tool for studying a wide range of materials. It is well suited for investigating living matter, for example, in single-cell neutrophil studies.
