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... (read more) -
Inhibiting Ice Recrystallization by Corn Cob Hemicelluloses
The Problem:โ 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... (read more) -
Molten Salt Assisted Pyrolysis Recycling of Glass Fiber Reinforced Polymer Composites
The Problem:โ Glass fiber reinforced composites (GFRPs) make up approximately 90% of all produced fiber-reinforced composite materials. Disposal of end-of-life composite parts and composite manufacturing waste has become more difficult with expanding landfill regulations, and recycling of glass fibers in is particularly challenging since state-of-the-art...

A Novel Method for the Production of Acrolein and Acrylic Acid from Glycerol in Carbon Dioxide Media
The Problem Worldwide biodiesel production is creating an overabundance of crude glycerol. It is projected that by the year 2020, the supply of glycerol will be six times more than demand. Therefore, development of sustainable processes for utilizing this organic raw material is important for the biodiesel industry. Acrolein can be produced via... (read more) -
Simultaneous Production of Lactic Acid and Propylene Glycol from Glycerol Using Solid Catalysts without External Hydrogen Supply
The Problem: Worldwide biodiesel production is increasing every year with regulatory and socioeconomic incentives to develop renewable fuels and energy. One mole of glycerol is generated along with every mole of triglyceride converted to biodiesel. As a result of the increase in biodiesel production, large amounts of glycerol are produced as a by-product.... (read more) -
Fast Separation of Rare Earth Elements Using Gas Thermochromatography
The Problem:The rare earth element market is heavily controlled by China, but to reduce reliance on China for these materials, more efficient extraction techniques are needed. However, conventional solution-phase techniques used to separate rare earth elements are generally slow and costly and require extensive sample preparation.The Solution:Researchers... (read more)
