GaAs(1-y-z)P(y)Bi(z) - New Near Lattice-Matched Materials to GaAs

Susan E. Babcock*, April S. Brown^, Maria Losurdo**, Thomas F. Kuech*, Luke J. Mawst*, Dane Morgan* *University of Wisconsin - Madison, ^Duke University, **Institute of Inorganic Methodologies and Plasmas (IMIP), CNR, Bari, Italy
The IRG has developed a new material, GaAs1-y-zPyBiz, as an alternative to the nitride–based bismide materials, specifically GaAs1-y-zBiyNz. Alloying in both Bi and N complicates growth, since both elements are sparingly soluble in GaAs. GaAs1-yPy,

Soft Robotic Concepts in Catheter Design: an On-demand Fouling-release Urinary Catheter

V. Levering, Q. Wang, P. Shivapooja, X. Zhao, and G. P. López - Duke University
Biofilms form on submerged or moist surfaces when bacteria attach and excrete slimy biopolymers to protect themselves, and they are particularly problematic when they develop on urinary catheters.

Patterning and Actuating Soft Materials

Daniel Morales, Etienne Palleau, Orlin Velev, Michael Dickey Department of Chemical and Biomolecular Engineering, NC State University
This image is a photograph of a pattern of copper ions in a hydrogel. Anodizing a penny (copper) in contact with a negatively charged polyelectrolyte hydrogel creates the pattern. These patterned regions have several interesting implications: 1. It creates patterns of ions (so-called ‘ionoprinting’) that are stable in water.  Patterned ions may be useful as tools for studying biology (e.g., Ca ions are critical in biology).
