The morphology of the Martian surface

Space Science Reviews, 1980
Most of the southern hemisphere of Mars is densely cratered and stands 1–3 km above the topographic datum. The northern hemisphere is more sparsely cratered and elevations are generally below the datum. A broad rise, the Tharsis bulge, centered at 14° S, 101° W, is 8000 km across and 10 km above the datum at its summit. The densely cratered terrain has

Morphological modelling of surfaces

Surface Engineering, 1998
For various types of surfaces, such as rough surfaces, coatings, and interfaces, there is a need for morphological characterisation and modelling. Morphological properties of surfaces obtained from image analysis techniques can be used to provide quantitative data on surface topography, including size distribution of peaks and valleys, connectivity ...

Morphology and surface properties of fumed silicas

Journal of Colloid and Interface Science, 2005
Several series of fumed silicas and mixed fumed oxides produced and treated under different conditions were studied in gaseous and liquid media using nitrogen and water adsorption-desorption, mass spectrometry, FTIR, NMR, thermally stimulated depolarization current (TSDC), photon correlation spectroscopy (PCS), zeta potential, potentiometric titration,

Bone response to implant surface morphology

The Journal of Arthroplasty, 1998
This study was designed to measure implant osseointegration using different surface treatments. Bilateral distal intramedullary implantation of titanium cylinders 25 mm x 5 mm was performed in 60 rabbits. The 3 surfaces tested were fiber mesh, mean pore size 400 microns; grit-blasted, mean surface roughness 6 microns; and acid-etched, mean surface ...

Morphological Surface Modification

2015
Surface modification approaches can be mainly regarded as by either a physical or a chemical means (note the biological ones are considered as a subset of chemical ones), or both. This chapter focuses on the physical means, particularly, a morphological approach to surface modification.

Morphology of the Lunar Surface

1969
In the preceding Chapters 13 and 14 we got acquainted with the methods and results of the determination of lunar coordinates, which have provided the basis for lunar mapping described in Chapter 15, and made possible a topographic description of the surface of the Moon with its almost innumerable and diverse features.

Morphology of the Fan Surface

2018
Vertical incision and lateral shifting of channels across the fan form a characteristic stepped fan morphology. The incised channels are often punctuated by backfillings that become with time entrenched again and finally display inset terraces. The fan surface displays both grain roughness and a microtopography roughness which gradually diminish with ...

The surface morphology of the avian tectorial membrane

Hearing Research, 1989
The structure of the tectorial membrane of the chick was evaluated by scanning electron microscopy (SEM), using standard techniques, and, for the first time, by studying unfixed tectorial membranes with video-enhanced light microscopy techniques (AVEC-DIC).

Structured Surfaces and Morphological Wetting Transitions

Interface Science, 2001
Recent theoretical and experimental studies have shown that structured surfaces, which contain patterns of lyophilic surface domains, lead to morphological wetting transitions at which the wetting layer changes its shape in a characteristic and typically abrupt manner.

Deformation and Surface Morphology

2000
The change of crystal surface morphology as a result of deformation by twinning and mainly by dislocationinduced slip is shown to reveal a pronounced hierarchy in scales (slip lines to slip band, slip band bundles and deformation bands). The basic dislocation mechanisms of their development and experimental methods for their investigations (optical and
