Functionalizing Carbon Nanotube Forests With 1,5-Diaminoaphthalene, Ben Pound, T. -C. Shen
UCUR
Carbon Nanotube (CNT) Forests are vertically grown carbon nanotubes. They can be as tall as millimeters, with radii from less than one nanometer (single-walled) to tens of nanometers (multi-walled). Their high surface area to volume ratio provides a unique material system for biosensor applications. However, the CNT surface does not provide covalent bonding sites to many antibodies of interest. One approach is to attach linker molecules with aromatic rings via π-stacking to the CNT surface and activating the linker molecules to bind covalently to specific antibody molecules. Unfortunately, the conventional solution-based functionalization approach often leads to collapse of the CNT …

Characterizing Sky Variability For Multi-Messenger Astronomy, Rachel Nydegger

Multi-messenger astronomy employs both electromagnetic and gravitational -wave detectors to paint a richer picture of celestial objects, providing more depth and information. The interferometers utilized for gravitational-wave observations receive input from very broad fields of view on the sky, typically a few square degrees. To have simultaneous electromagnetic observations (typically less than one square degree) requires innovative techniques for the telescopes to find the origin of radiation. One idea is to “tile” the view of the interferometer, using multiple telescopes to simultaneously point at different areas of the field to observe the source. One di"culty of this observing paradigm is …
