Surface Controlled Dislocation Multiplication in
Metal Micro-pillars,
Wei Cai and Christopher R. Weinberger
Abstract: Understanding plasticity and strength of crystalline materials in terms of the dynamics of microscopic defects has been a goal of materials research in the last seventy years. The size-dependent yield stress observed in recent experiments of sub-micrometer metallic pillars provides a unique opportunity to test our theoretical models, allowing the predictions from defect dynamics simulations to be directly compared with mechanical strength measurements.
While easy escape of dislocations from sub-micrometer pillars is expected and provides a plausible explanation of the observed size-effect, we predict the opposite to be true in body-centered-cubic (BCC) pillars through a series of Molecular Dynamics and Dislocation Dynamics simulations. Under the combined effects from the image stress and the atomistic core, a dislocation nucleated from the surface of a BCC pillar generates one or more dislocations moving in the opposite direction before it exits from the surface. The process is repeatable so that a single nucleation event is able to produce a much larger amount of plastic deformation than that in face-centered-cubic (FCC) pillars. This self-replication mechanism calls for a different explanation of the size-dependence of yield stress in FCC and BCC pillars.

BME Seminar: William Murphy, University of Wisconsin. "Bio-inspired Assembly of Functional Materials
Thursday May 15, 2008 at 4:00 PM — Tech M345
Control over the molecules that cells encounter in their local environment is a common theme in natural tissue development. Similarly, schemes to mimic development and “engineer” functional tissues are likely to benefit from control over the cell’s local signaling environment. This concept is particularly important in stem cell-based applications, in which local signaling can direct cell fate. We are interested in assembling biomaterials that are capable of actively communicating with stem cells. To achieve cell-material interaction, we use specific, reversible interactions to build biomaterials with new capabilities, including bio-responsiveness and regulated soluble signaling. Approaches highlighted in this talk will include non-covalent assembly of biomolecules (e.g. proteins, DNA) on engineered surfaces and within synthetic hydrogels.
