Science, 1984
Since the discovery in 1969 of a man-made surface-active material that would bond to bone, a range of materials with the same ability has been developed. These include glass, glass-ceramic, and ceramic materials which have a range of reaction rates and from which it should be possible to select a surface-active material for a specific application.

Surface-Active Particles with Microstructured Surfaces
Langmuir, 2005Interfaces adsorbing solid particles have recently attracted great attentions in the field of materials science, because they are useful as templates of well-ordered particle arrays or of microstructured hollow spheres. The solid particles are adsorbed at the interfaces and form self-assembled structures when the particles have suitable wettability to ...

Surfactants are characterized by their ability to reduce the surface tension of aqueous fluids; this enables them to act as detergents, wetting agents, emulsifiers. James (1965) has defined them as molecules with two different structural elements, one being a hydrophobic hydrocarbon (water-repellent) group, and the other a hydrophilic polar (water ...

Spatiotemporal Addressing of Surface Activity
Science, 2001We have modified surface catalytic activity in real time and space by focusing an addressable laser beam to differentially heat a platinum (110) single-crystal surface. Ellipsomicroscopy imaging of local conditions (such as reactant and product local coverages) enabled us to close the loop between sensing and actuation (both spatiotemporally resolved).

Cell Surface Glycosyltransferase Activities
1980Publisher Summary Three basic components are involved in the reactions catalyzed by glycosyltransferases. These are the enzyme itself, a sugar donor, and a sugar acceptor. Often divalent cations are needed for catalytic activity. Another component, α-lactalbumin also participates in the reactions of some galactosyltransferases.

Journal of Colloid and Interface Science, 1969
Abstract The effects of high concentrations of urea to increase surface pressure and alter surface potentials of stearic and palmitic acid monolayers were examined at temperatures between 15° and 40°C. Results of the investigation show that penetration of urea into an interfacial region depends upon the presence of molecules at the interface, where ...

Active Contours and Active Surfaces
2012Active contours and active surfaces are means of model-driven segmentation. Their use enforces closed and smooth boundaries for each segmentation irrespective of the image content. They are particularly useful if such properties cannot be derived everywhere from the data.
