In addition to the already discussed influence of the actual micro topography at the coordination point, other conditions may influence the true adhesion forces that act between the solid partners. In the case of van-der-Waals forces the average distance a as shown in Section 5.1.1, Fig. 5.11, may be changed by the presence of adsorption layers (Fig. 5.23). 

Mass-movement topography and relating micro-topography mapping... 

Step C Landform unit map/landform classification map is prepared using the above topographic map. The map should contain mass-movement topography and relating micro-topography such as valley head slope, head hollow, knick line. 

Figure 11. Probable shallow landslide blocks estimated from topsoil depth and micro-topography (Topsoil depth was measured by SSP, micro-topography was described by surface survey using LiDAR).

Estimation of probable shallow landslide blocks by traverse measurement of topsoil Hazard mapping using SSP was demonstrated at a hill slope composed of granite and compared with micro-topography observed by field investigations and LiDAR measurements.

Micro topography On smooth surfaces, the cells are able to spread, perhaps forming greater number of hemi-desmosomes as anchors to the substrate. In contrast, on rougher surfaces, the cells appear to form local contacts that allow the cells to span across the space between surfaces [21]. 

The full investigation of the tribocorrosion tests requires generally the use of in situ tools like open circuit measurements, polarization measurements, current transients, impedance spectroscopy, and noise measurements, and ex situ tools like elemental surface analysis techniques, optical or electron microscopy, micro-topography, micro and nanohardness measurements texture and internal stress analyses.

The analysis of biomolecules by AFM is sometimes [3] referred to as surface biology, as opposed to the so-called test-tube biology, because the immobilisation of oligonucleotides on sohd surfaces is central to the design, fabrication and operation of DNA-based microdevices, such as biosensors, DNA micro- and nanoarrays, microPCR and lab-on-a-chip devices. As the analysed biomolecules are in close contact and very often in intimate interaction with the surface, sample preparation for the AFM analysis of surface-immobihsed biomolecules is both critical and dehcate. The biomolecules need to be firmly anchored on the substrate, which has to have a sufficiently minimal or easily discriminated topography [1]. The Kleinschmidt method [6] for the DNA...
