71. In situ Mapping and Characterization of Biodegradable Polymers within Soil Bacteria using Surface-Enhanced Micro-Raman Spectroscopy
Published: Date unknown
Authors: Santanu S. Kundu, Michael S. (Michael Stephan) Waters, Irene G. Calizo, Angela R Hight Walker, Kathryn L Beers
Abstract: Several species of environmental bacteria can be optimized to produce commercially harvestable biodegradable polymers (e.g. polyhydroxyalkanoates), and to degrade pollutants (e.g. halogenated aromatic compounds). Polyhydroxyalkanoates (PHAs) are incr ...

72. Magnetic Field-Induced Biomimetic Self-Assemblies of Cobalt Nanoparticles
Published: Date unknown
Authors: Guangjun Cheng, D B Romero, Angela R Hight Walker
Abstract: Under the influence of a 300-Guass magnetic field, 15-nm Co nanoparticles can assemble into centimeter-long rigid chains in the colloidal solution. The magnetic field-induced (MFI) chains are retained after the removal of the magnetic field, but they ...
