Para hydrogen induced polarization in hydrogenation reactions

TL;DR: This setup condenses the PHIP protocol into a pulse-program that can be readily shared in the manner of traditional pulse sequences and speeded calibration and improved quality assurance by enabling the B0/B1 fields to be tuned based on the direct acquisition of thermally polarized and hyperpolarized NMR signals.

TL;DR: Recent trends both on the characterization of immobilized homogeneous transition metal catalysts and onThe characterization of surface species on transition metal surfaces are presented.

TL;DR: It is demonstrated for the first time that, contrary to these expectations, supported metal catalysts such as Pt/Al2O2 and Pd/ Al2O3 do exhibit PHIP effects and can be used for the production of spin-polarized fluids for MRI applications and for developing new research tools for mechanistic and kinetic studies on heterogeneous hydrogenation processes.

TL;DR: The feasibility of propane hyperpolarization via hydrogenation of cyclopropane with parahydrogen with NMR signal enhancement sufficient for 2D gradient echo MRI of ∼5.5 mL phantom with 1×1 mm2 spatial resolution and 64×64 imaging matrix is demonstrated.
