WebApr 8, 2024 · To detect the interaction of anle138b with both fibrils as well as intermediate-I of αS, [23] we recorded dynamic nuclear polarization (DNP) enhanced MAS NMR [46] spectra in the presence of the bi-radical TEMTriPol-1 [52].We prepared the samples in a glass-forming matrix of glycerol-water, added TEMTriPol-1 and cooled to 100 K [48], … Dynamic nuclear polarization (DNP) results from transferring spin polarization from electrons to nuclei, thereby aligning the nuclear spins to the extent that electron spins are aligned. Note that the alignment of electron spins at a given magnetic field and temperature is described by the Boltzmann distribution under the thermal equilibrium. It is also possible that those electrons are aligned to a higher degree of order by other preparations of electron spin order such as: chemic… how to remove wall thermostat
