Collaborative Research: Investigating Bacteria-Surface Interactions by Surface Engineering and Mathematical Modeling
0.0 out of 5 stars
12 Jan 2011 | Poster | Contributor(s): Dacheng Ren
Biofilms are surface-attached highly hydrated structures comprised of a polysaccharide matrix secreted by the bound microbial cells. It is well documented that biofilm cells are up to 1000 times more …
Collaborative Research: Stick-slip dynamics of micromachined interfaces
10 Jan 2011 | Poster | Contributor(s): Maarten P de Boer
Friction-based stepper motors provide a powerful actuation mechanism in micro- and nanomechanics Applications include valves, optical components (mirror and fiber positioning), memory addressing, …
Nanomechanical material size effects using an in-situ, on chip test platform
Many micro- and nanoscale materials of interest (e.g., polycrystalline silicon, silicon carbide, carbon-based solids) are brittle. Strength of brittle materials is not single valued, but is …
Mechanics of self-assembled peptides
10 Jan 2011 | Poster | Contributor(s): Justin Barone
Many systems, including peptide systems, have been identified that self-assemble into nanometer sized structures. However, continued self-assembly to the macroscopic scale has remained elusive even …
Understanding and Controlling Coupled Mechanical and Chemical Degradation Phenomena within Insertion Electrodes

Design and Manufacture of Ultra-High Temperature Ceramic Composites with Ceramic Reinforcing Phases (CeraSGel)
07 Jan 2011 | Poster | Contributor(s): Manuel Acosta
The need for materials that would enable maneuverability during hypersonic flight in atmosphere re-entry conditions has focused materials scientists on the study of Ultra-High Temperature Ceramics …
Surface Modification of Bulk-Metallic Glasses by a Laser-Peening Process
04 Jan 2011 | Poster | Contributor(s): Peter K Liaw
Laser shock peening (LSP), as a modern surface-enhancement method, can introduce residual-compressive stresses and shear bands on the surface of Bulk-Metallic Glasses (BMGs), both of which are …
The Design and Analysis of AluminideSurface Layers for Low Temperature Synthesis
04 Jan 2011 | Poster | Contributor(s): John H Perepezko
In order to realize the enhanced capabilities of high temperature alloy steels for higher energy efficiency, they must be protected against environmental attack. The application of aluminide coatings …
