Applications of Morphological Operations in Surface Metrology and Dimensional Metrology [PDF]
, 2013 In contrast to the widely used mean-line based evaluation techniques, the capabilities of morphological methods are not fully recognized in practice. Morphological operations, e.g.

The influence of surface clinker on the crustal structures and dynamics of 'a'ā lava flows. [PDF]
, 2010 Surface structures on 'a'ā and blocky lavas reflect the internal flow dynamics during emplacement and also influence the dynamics of developing flows.

Surface-chemical and -morphological gradients [PDF]
Soft Matter, 2008 Surface gradients of chemistry or morphology represent powerful tools for the high-throughput investigation of interfacial phenomena in the areas of physics, chemistry, materials science and biology. A wide variety of methods for the fabrication of such gradients has been developed in recent years, relying on principles ranging from diffusion to time ...

Evidence of coastal landforms and age determination related to the sealevel change at Nakhon Si Thammarat province in southern Thailand [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2023 We present evidence of sea-level changes over the past 15,000 years from dating sandy beach sediments in Nakhon Si Thammarat province. First, we classified various types of coastal landforms from satellite images.

Evidence for intermolecular forces involved in ladybird beetle tarsal setae adhesion
Scientific Reports, 2021 Why can beetles such as the ladybird beetle Coccinella septempunctata walk vertically or upside-down on a smooth glass plane? Intermolecular and/or capillary forces mediated by a secretion fluid on the hairy footpads have commonly been considered the ...

Mini Review: Comparison of Bio-Inspired Adhesive Feet of Climbing Robots on Smooth Vertical Surfaces
Frontiers in Bioengineering and Biotechnology, 2021 Developing climbing robots for smooth vertical surfaces (e.g., glass) is one of the most challenging problems in robotics. Here, the adequate functioning of an adhesive foot is an essential factor for successful locomotion performance.

Morphology and surface reconstructions of GaN(11̄00) surfaces [PDF]
Applied Physics Letters, 2003 GaN is grown by plasma-assisted molecular-beam epitaxy on ZnO(11̄00) substrates. Well-oriented (11̄00) GaN surfaces are obtained, and (11̄01) oriented facets are also observed. On the GaN(11̄00) surfaces under Ga-rich conditions, a surface reconstruction with approximate symmetry of “4×5” is found.

Surface Morphology of GaN: Flat versus Vicinal Surfaces [PDF]
MRS Internet Journal of Nitride Semiconductor Research, 1999 The surface morphology of GaN films grown by molecular beam epitaxy (MBE) is investigated by scanning tunneling microscopy (STM). A comparison is made between flat and vicinal surfaces. The wurtzite structure of GaN leads to special morphological features such as step pairing and triangularly shaped islands.

Anisotropic Drop Morphologies on Corrugated Surfaces [PDF]
Langmuir, 2008 The spreading of liquid drops on surfaces corrugated with micron-scale parallel grooves is studied both experimentally and numerically. Because of the surface patterning, the typical final drop shape is no longer spherical. The elongation direction can be either parallel or perpendicular to the direction of the grooves, depending on the initial drop ...
