Scanning electrochemical microscopy (SECM): an investigation of the effects of tip geometry on amperometric tip response
Article Abstract:
A study was conducted to simulate transient and steady-state amperometric tip responses with an alternating direction implicit algorithm using scanning electrochemical microscopy. The shape of the approach curves were analyzed for various electroactive disk to insulator radii ratios. The topographical sensitivity and spatial resolution of the scanning electrochemical microscope were evaluated using simulated results. Findings indicated that the diffusion round the edge of the insulating sheat had a significant effect on the approach curves.

Pattern formation and morphology evolution in Langmuir monolayers
Article Abstract:
The study of how patterns formed by Langmuir domains of a stable phase propagate into a metastable one and the morphology transition from tip splitting to side branching are presented. A model for monolayer growth is presented that can be related to the theory of dynamic phase transitions developed by Muller-Krumbhaar and collaborators, where morphological structures and morphological transitions are obtained.

Microfabrication using elastomeric stamp deformation
Article Abstract:
Elastomeric stamp deformation was used to fabricate a series of new metal thin film patterns not present on the original stamp. The rounded patterns are of nanoscale thickness, long-range order, and are created from elastomeric stamps with only straight-edged features and the feature size, separation, relief height, stamp elasticity and external force control the morphology and appearance of shape.
