Surface Structural Characterization of Polymer Composite Insulators for Improved Weather Resistance
Award Summary: To date, testing of some materials such as silicone and EPDM (ethylene propylene diene monomer) rubbers has been carried out, and some general findings exist, but it remains to be understood how the materials respond to weathering under their electrical load. In this project, a combination of surface-specific spectroscopy, microscopy, and macroscopic measurements…
An automated image analysis platform for the study of weakly – adhered cells
Abstract Details of the design and implementation of an open-source platform for studying the adhesion of cells attached to solid substrata are provided. The hardware is based on a laser-cut flow channel connected to a programmable syringe pump. The software automates all aspects of the flow rate profile, data acquisition and image analysis. An example…
High-level characterization of the effects of de-icing salts on polymer composite insulator shed hydrophobicity and monomer leakage
High-level characterization of de-icing salts on polymer composite insulator Award Summary: To evaluate the long-term effects of corrosive conditions (particularly the use of de-icing salts) on the hydrophobicity of silicone used on polymer composite electrical insulators. Used a variety of analytical methods to better understand the effects of simulated ageing on polymer samples. These methods…
