Today no exercises at physiotherapy, but the “hardening” in the rectus femoris muscle just above the patella was massaged loose. I’d been bothered by it for a few days. However, it’s not something to worry about.

It’s been online for a while already, but I’m sharing it here anyway: "Quantitative Trace Analysis of Dilute Mixtures Using a Benchtop NMR System with SABRE Hyperpolarization" by Bono Jimmink and Mattia Negroni #HISCORE pubs.acs.org/doi/10.1021/...
Quantitative Trace Analysis of Dilute Mixtures Using a Benchtop NMR System with SABRE Hyperpolarization
Despite their modest sensitivity, benchtop NMR spectrometers have recently attracted a great deal of attention, because of their low cost, high portability, and robustness. A solution to the sensitivity limitation of benchtop spectrometers is offered by nuclear spin hyperpolarization, by which large NMR signal enhancements can be realized. Signal Amplification By Reversible Exchange (SABRE) is one-such hyperpolarization technique, which utilizes hydrogen enriched in the para spin-isomer (pH2). However, the application of SABRE with benchtop NMR has so far largely been restricted to sample concentrations in the millimolar range. In this work, we present SABRE hyperpolarization of a mixture at micromolar concentrations, measured on a 1 T benchtop spectrometer. The observed linear dependence between hyperpolarized signals and concentration demonstrates the stability of our approach, which allows quantification in the micromolar range.

Madonna - True blue
A nice album for a quiet evening. I can’t really say much about it — I don’t even know how I got it. Probably something from or for my girlfriend. Although “Open Your Heart” does sound quite catchy.
