Electret Filter Media with Biodegradable & Thermoplastic Fibers
High-Filtration, Biodegradable Nonwoven Fabrics The Problem: Nonwoven fabrics used in filtration media and devices are primarily made from non-biodegradable materials such as polyester and polypropylene. Such filtration media, especially single-use filtration media such as masks and wipes, are a substantial contributor to plastic pollution. This evidences...

Structured Glass-Ceramic Scintillators
The Problem: For portal imaging at MeV energies, electronic portal imaging devices (EPIDs) based on indirect flat panel detector (I-FPD) technology, as depicted below, have become standard. The highest-performing I-FPDs that are currently available have very low (~1%) detective quantum efficiency (DQE) performance at MeV energies. This limitation is...

A Charge Pump Gate Drive for SiC MOSFETs to Reduce Switching Losses
The Problem:Compared to other transistors, silicon carbide (SiC) MOSFETs have improved properties due to lower conduction loss and specific capacitance and higher switching speed and maximum junction temperature. However, high turn-on switching losses due to lower transconductance remains a problem; thus, it is still difficult to implement SiC MOSFETs...

Dynamic Mixer for 3D Printing Fiber-Containing Reactive Polymer Systems
The Problem:Large-scale additive manufacturing (AM) of thermoset polymer composites requires mixing of fiber-containing components at the point of deposition. Traditional baffle-type passive mixers significantly increase the energy and pressure required to pump material while also limiting the fiber content in the deposited material. Passive-type mixers...
