In this Director's Research Initiative (DRI) effort, we have developed surface treatments with cleavable Diels-Alder bonds that allow for a transition between wetting and non-wetting conditions via a combination of thermal and chemical treatments. These treatments are applied internally to glass capillaries to demonstrate the applicability of the technique for regulating flow in synthetic vascular systems. This report is a programmatic summary and will be supplemented by a complete technical ...
Fibers incorporated into polymer matrices suffer from poor adhesion at the fiber-resin interface. In ballistic materials such as body armor, it is imperative that the fiber-resin interface is strengthened for superior energy absorbing capabilities. To address this need, fibers are typically subjected to surface modifications. The overall aim of this work is to establish a methodology of controlling the interfacial adhesion by controlling the degree of chemical bonding between the ...
We report a highly sensitive, rapid and reliable method for the detection of Bacillus Anthracis spores at 300/mL using a piezoelectric-excited millimeter-sized cantilever (PEMC) sensor. Antibody specific to Bacillus anthracis (BA, Sterne strain 7702) spores was immobilized on PEMC sensors, and exposed to spores (300 to 3x106 spores/mL). The resonant frequency decreased at a rate proportional to the spore concentration and reached a steady state frequency change of 5 plus/minus ...
