Reversible Parahydrogen Induced Hyperpolarization of N-15 in Unmodified Amino Acids Unraveled at High Magnetic Field

Autor: Ewoud Vaneeckhaute, Jean‐Max Tyburn, James G. Kempf, Johan A. Martens, Eric Breynaert

Amino acids (AAs) and ammonia are metabolic markers essential for nitrogen metabolism and cell regulation in both plants and humans. NMR provides interesting opportunities to investigate these metabolic pathways, yet lacks sensitivity, especially in

Hyperpolarization using signal amplification by reversible exchange (SABRE) relies on target molecules and parahydrogen coordinating to a transition metal catalyst. Identification of this coordinated state becomes increasingly important, especially s

The morphology of zeolite W (MER topology) synthesized from Hydrated Silicate Ionic Liquids (HSILs) shows a distinct temperature dependence, reflected in a fundamental difference in the underlying crystal growth mechanism as revealed by Atomic Force

Symmetry breaking of parahydrogen using iridium catalysts converts singlet spin order into observable hyperpolarization. In this contribution, iridium catalysts are designed to exhibit asymmetry in their hydrides, regulated by in situ generation of d
