Analysis of chemical exchange in iridium N-heterocyclic carbene complexes using heteronuclear parahydrogen-enhanced NMR

Communications Chemistry
The signal amplification by reversible exchange process (SABRE) enhances NMR signals by unlocking hidden polarization in parahydrogen through interactions with to-be-hyperpolarized substrate molecules when both are transiently bound to an Ir-based ...

Simulation of ideal-gas flow by nitrogen and other selected gases at cryogenic temperatures [PDF]

The real gas behavior of nitrogen, the gas normally used in transonic cryogenic tunnels, is reported for the following flow processes: isentropic expansion, normal shocks, boundary layers, and interactions between shock waves and boundary layers.

Current state of the art of analyte scope in urine metabolome analysis by non-hydrogenative PHIP

Journal of Magnetic Resonance Open
Non-hydrogenative PHIP (nh-PHIP) is an NMR signal enhancement technique that offers several orders of magnitude gains in detection sensitivity. It is one of the few hyperpolarization methods that have been demonstrated to be applicable to chemical ...

Formulation of a nonanalytic equation of state for parahydrogen

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1969
A method is described for building an equation of state which gives an infinite specific heat C v at the critical point approached from the one-phase domain. Interpolated PVT data are used on isochores up to 100 K at densities to the liquid triple point.
