Detailed temperature dependence of the low-field ALC in TMS-Pentacene
We wish to investigate the evolution of the low-field ALC peaks with temperature of TMS-Pentacene, so we can extract the temperature dependent electron spin relaxation rate. Our... -
A GENERAL METHOD OF MEASURING ANTIOXIDANT CAPACITY
Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which... -
Probing the [FeFe]-hydrogenase using muon spectroscopy
During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra... -
