In this report, we summarize the results of research related to development of an electrically-triggered reversible-adhesive material. The material is made of an epoxy comprised of diglcidyl ether of bisphenol-A (DGEBA) and 4,4’-diaminodiphenylsulfone (DDS). By combining the epoxy with PCL a “bricks and mortar” morphology is created with reversible adhesion properties. A phenomenon known as differential expansive bleeding (DEB) is the driving force of the self-healing and reversible-adhesion. The epoxy/PCL was embedded within electrically conductive carbon nanofibers (CNF) created from electrospun poly(acrylonitrile) (PAN). The material’s high conductivity allowed convenient heating with a power source. Initial tests revealed a lack of …

The purpose of this project was to develop a laboratory experiment to be conducted by future Nuclear Engineering Track (NET) students that adequately demonstrates adsorption of the lanthanide neodymium, an extraction technique used in nuclear fuel reprocessing. Nuclear fuel reprocessing is the chemical separation of various elemental components in spent nuclear fuel. These components, once isolated, can be recycled or reused and ultimately minimize the volume of radioactive waste. There were several steps taken to accomplish this task. First, an independent study of Dr. Hyung Jun Park’s work on phosphorus based adsorbents was conducted. Research was also done on current …
