Control of crystal nucleation by patterned self-assembled monolayers
Article Abstract:
It seems likely that high-resolution crystallization on the X-terminated regions of patterned self-assembled monolayers (SAMs) reflects the influence of mass transport, according to research involving patterning SAMs on metal substrates by microcontact printing with an elastomeric stamp. It proved possible to control the most important characteristics of the crystallization process, including the location and density of nucleating regions on the surface, by adjusting the pattern, density and sizes of features in the stamp, the functionality of the surface of the SAM and the concentration of the crystallizing solution.

Controlling local disorder in self-assembled monolayers by patterning the topography of their metallic supports
Article Abstract:
Micropatterning as a method of controlling surface properties has applications in many fields, including electronics and cell biology. A new and simple way to pattern microscopic surface structures uses self-assembled monolayers deposited on topographic islands on a metal surface. The study shows that disorder is greater at the step edges, creating fine-scale surface-energy inhomogenities that can be selectively etched.

Like-charged particles at liquid interfaces
Article Abstract:
The attraction that occurs between the micrometre-sized particles absorbed at an aqueous interface is caused by distortion of the liquid interface. The sum total of the electrostatic pressure acting on the liquid interface is described to be equivalent to an external force.
