SABRE-hyperpolarization dynamics of [1-13C]pyruvate monitored by in situ zero- to ultra-low field NMR

Journal of Magnetic Resonance Open
Hyperpolarized [1–13C]pyruvate is the leading metabolite used in the emerging field of hyperpolarization-enhanced MRI. Signal amplification by reversible exchange (SABRE) is a straight forward hyperpolarization method that has recently been shown to ...

Ortho-parahydrogen catalyst test facility

IOP Conference Series: Materials Science and Engineering
Abstract With the growing interest in hydrogen as one pillar of the future energy economy, the relevance of hydrogen liquefaction for storage and transportation is increasing rapidly. However, the liquefaction process still offers much potential for improvement in terms of cost and efficiency.

Quasi-1D parahydrogen in nanopores

, 2015
The low temperature physics of parahydrogen (ph2) confined in cylindrical channels of diameter of the order of 1 nm is studied theoretically by Quantum Monte Carlo simulations. On varying the attractive strength of the wall of the cylindrical pore, as well as its diameter, the equilibrium phase evolves from a single quasi-1D channel along the axis, to ...

Probing nanoparticle proximity effects on selective butadiene hydrogenation over Pd-Au/TiO2 with parahydrogen-induced polarization NMR

Journal of Magnetic Resonance Open
Selective butadiene hydrogenation to butene is a crucial process in the petrochemical industry, however, a comprehensive understanding of the underlying structure-activity relationships remains elusive.

Overhauser enhanced liquid state nuclear magnetic resonance spectroscopy in one and two dimensions

Nature Communications
Nuclear magnetic resonance (NMR) is fundamental in the natural sciences, from chemical analysis and structural biology, to medicine and physics. Despite its enormous achievements, one of its most severe limitations is the low sensitivity, which arises ...
