Growth morphologies of crystal surfaces

Physical Review A, 1991
A previously proposed Monte Carlo model (Xiao et al., 1988, 1990) is extended to three dimensions, and reevaporation after accommodation and growth on dislocation-induced steps are included. It is found again that, for a given set of growth parameters, the critical size beyond which a crystal cannot retain its macroscopically faceted shape scales ...

Reflections on surface morphology

Nature Energy, 2021
Electrochromic windows can reduce buildings’ energy demand and improve occupants’ comfort, yet they struggle to fully meet market needs. Now, researchers demonstrate that polymer additives improve light and solar heat modulation of reflective electrochromic windows, with potential for durable, large-scale and low-cost manufacturing.

Comparison of Catheter Surface Morphologies

British Journal of Urology, 1990
Summary— The surface morphologies of different generic types of Foley catheter have been investigated using scanning electron microscopy (SEM). The characteristic features of each material are illustrated and it is shown that distinct differences exist between the inner and outer surfaces of latex‐based ...

Vermiculite Surface Morphology

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1963
Abstract A study of the surface morphology of vermiculites from several different sources by the electron microscope has indicated that, unlike the smooth surfaces of micas, the vermiculite surfaces show micromorphological structural variations such as small humps, prominent crystallographic steps on the basal cleavage planes ...

Antifrosting Performance of a Superhydrophobic Surface by Optimizing the Surface Morphology

Langmuir, 2020
Improving the antifrosting ability of stainless steel is crucial. In previous reports, many efforts have been dedicated to enhancing the antifrosting performance of superhydrophobic surface by fabricating different surface morphology. However, no researchers have proposed what kind of surface morphology can effectively prevent the frost based on the ...

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

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,

Surface morphology of Asian cadaveric hips

The Journal of Bone and Joint Surgery. British volume, 1985
The joint surfaces of 60 hips obtained from the cadavers of elderly Asians were studied to determine the incidence, the grade and the distribution of both non-progressive (age-related) and progressive degenerative changes. It was observed that in the Asian population of 40 to 90 years of age, non-progressive changes were common, being seen in 66% of ...

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

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.
