Impact Of Next Generation Am-Pet Helmet And Support Structure On Subjects' Neck, Samantha Melroy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ambulatory Micro-dose Positron Emission Tomography (AM-PET) is a portable PET brain scanner that does not require patients to remain still but allows them to move as they regularly would over the course of the scan (i.e. clapping hands, walking in place, and other stationary movements). Traditional PET scanners require patients to remain still for an extended duration in a small confined cavity. This is problematic for those who have conditions such as Parkinson's and Autism; in many cases, they must be sedated before the test can be performed. West Virginia University's AM-PET Helmet allows for these regular human movements to …

Redox Stable Anode Materials For Sofc Application, Tony Thomas Jan 2017

Redox Stable Anode Materials For Sofc Application, Tony Thomas

Graduate Theses, Dissertations, and Problem Reports (ETD)

The common material design for solid-oxide fuel cells (SOFCs) is based on the cermet (ceramic-metal composite) material group, for example anode compositions like nickel with yttria stabilized zirconia (Ni/YSZ). One of the main limitations of these material groups is that they may undergo unwanted thermal expansion during redox cycles, causing dimensional instability at the anode. The state-of-the-art Ni/YSZ anode experiences a linear expansion of up to 1% when oxidized, causing an irreversible microstructural change, decreasing the electrochemical activity. The problem cumulatively increases if the cell design is anode supported as this puts the electrolyte under tension, causing it to crack …
