Poly(Tetramethylene Oxide)-Based Segmented Ionenes Block Copolymer with Aliphatic or DABCO Hard Segments
Background Ionenes contain charges in their polymer backbones, as opposed to traditional ionomers that have charges on the pendant site of the backbone. Ionenes, whether positive or negative, typically fall into two categories- either segmented or non-segmented. Segmented ionenes contain alternating hard and soft segments along the polymer backbone,...

Zwitterion Anti-Scaling Membrane Coatings
Background Water reclamation for space flight applications (e.g., International Space Station (ISS)) requires complex engineering solutions to ensure maximum water recovery. Current vapor compression distillation (VCD) technologies are effective but produce highly concentrated brines and often cause scaling within a separation system. Scaling in water...

Carbonate-Infused Activated Carbon for Direct Air Capture Sorbents
­Background Removal of carbon dioxide (CO2) from the atmosphere by direct air capture (DAC) can be accomplished using two chief approaches, liquid and solid. Liquid systems pass air through chemical solutions containing basic ions (e.g., hydroxide ions or bicarbonate ions), heat the resulting mixture to release the captured CO2, and then reuse the...

Novel Method for Head & Neck and Respiratory Motion Correction in Positron Emission Tomography (PET)
The Problem: As the use of PET imaging continues to increase, it is imperative to address the current, inadequate means for motion correction. During PET imaging, a summation image is generated while the patient is instructed to lie still on his/her back for the duration of the scan. A typical PET scan lasts 15 to 30 minutes on average Patient motion...
