Computing surface curvature would seem to be a simple application of differential geometry, but problems arise due to noise and the quantized nature of digital images. We present a method for determining principal curvatures and directions of surfaces estimated from three-dimensional images.

Bioinspired Structured Surfaces
Langmuir, 2012Nature has evolved objects with desired functionality using commonly found materials. Nature capitalizes on hierarchical structures to achieve functionality. The understanding of the functions provided by objects and processes found in nature can guide us to produce nanomaterials, nanodevices, and processes with desirable functionality. Various natural

Controlling the Structure of Proteins at Surfaces
Journal of the American Chemical Society, 2010With the help of single molecule force spectroscopy and molecular dynamics simulations, we determine the surface-induced structure of a single engineered spider silk protein. An amyloid like structure is induced in the vicinity of a surface with high surface energy and can be prohibited in the presence of a hydrophobic surface.

The Interpolation of Object and Surface Structure
Cognitive Psychology, 2002One of the main theoretical challenges of vision science is to explain how the visual system interpolates missing structure. Two forms of visual completion have been distinguished on the basis of the phenomenological states that they induce. Modal completion refers to the formation of visible surfaces and/or contours in image regions where these ...

Surface Tension and Surface Structure of Water
Science, 1967The surface tension-temperature relationship for water is smooth and linear when account is taken of the expansion of the surface with temperature. This plot permits the calculation of thermodynamic properties for 1 square centimeter of surface. Molar surface quantities are derived by assuming a hexagonal water surface structure.

Abstract Having determined what types of atoms are present upon a surface, the next important problem is to discover their arrangements with respect to each other and with respect to the underlying atoms of the solid. There are two parts to this problem-the determination of the symmetry of the surface atomic arrangement and the ...
