Hyperpolarization Update #5 (the creation of frankencoil)

This tangle of copper tubing haphazardly patched together is Frankencoil.

A quick recap: I’m troubleshooting a setup to do hyperpolarization (a technique that allows us to take much faster measurements of samples using NMR). Our technique for performing hyperpolarization involves transferring nuclear spins from parahydrogen to our sample. Parahydrogen is a spin state of hydrogen that you make at low temperatures. Regular hydrogen will show […]

Hyperpolarization Update #4 (Trying to make Parahydrogen)

These are the promising initial measurements that I took. Black is the control measurements of regular hydrogen, red is the samples that I was trying to enrich, and green is 2/3 of the black measurements to give a rough baseline for how much reduction in signal I should be seeing.

So the stars aligned and everything that needed to happen for me to start testing parahydrogen production finally happened! (Are we making parahydrogen? Stay tuned to find out!) A quick recap: I’m troubleshooting a setup to do hyperpolarization (a technique that allows us to take much faster measurements of samples using NMR). Our technique for […]

Hyperpolarization Update #3 (and now for something completely different)

This is a picture of the first signal we received with the coil. The signal is the regular peaks in the darker color, which correspond to "echoes". When we do more echoes we are able to get information about the chemical environment by looking at how fast they shrink.

This past week was pretty slow on the hyperpolarization side of things, so I directed my energy to a project I’ve been working on since the second semester of my sophomore year: designing a new NMR probe for our magnet. We already have a probe that works, but we want to be able to make […]
