Hyperpolarization Update #7 (Well, that worked)

This is the first clear hyperpolarized measurement we took on the single-sided NMR. (This is a picture from my phone because we were having technical difficulties with saving single-scan data.) Compare to the second figure.

A quick recap: I’m troubleshooting a setup to do hyperpolarization, a technique that allows us to take much faster measurements of chemical samples using NMR (nuclear magnetic resonance, which uses magnets and radio pulses to give you information about chemicals, think MRI) . Hyperpolarization speeds up measurements because it increases the amount of signal you pick […]

Hyperpolarization Update #6 (I hyperpolarized a thing!)

The black line shows what the signal looks like before the sample is hyperpolarized, and the red line shows what the signal looks like after the sample is hyperpolarized. Notice that for each of the humps on the black line there is a much larger dip in the red line. (Hyperpolarization flips the sign of the signal so the bump goes down instead of up, but the important thing is that the bump is bigger.)

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 […]
