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...

Inhibiting Ice Recrystallization by Corn Cob Hemicelluloses
The Problem:​ When frozen foods, such as ice cream and frozen desserts, undergo ice recrystallization over time, they develop a gritty and icy texture. This recrystallization occurs with and without the temperature fluctuations. Currently, several polysaccharide gums, such as guar gum and locust bean gum, are used as stabilizers in ice cream to stabilize...
