Apologies for cross-posting this to people in several email lists
Next week we have two seminars on Thursday the 29th in the YNiC Open
Plan area.
At 2pm
There will be a talk entitled
"NMR and MRI sensitivity enhancement by Parahydrogen Induced Polarization"
by
Kerstin Münnemann
Max Planck Institute for Polymer Research, Mainz, Germany
Despite its wide applicability in chemistry, biology and medicine,
Nuclear Magnetic Resonance (NMR) spectroscopy still suffers from its
inherently low sensitivity. Exploiting the large signal enhancements
associated with hyperpolarization techniques, such as Parahydrogen
Induced Polarization (PHIP), however, NMR or MRI qualify for monitoring
dynamic processes in real time. In this lecture, the synthesis and
hyperpolarization of several biocompatible molecules like barbiturates,
Vinylpyrrolinidon (blood plasma expander) or Dimethylcarboxylat
(precursor to fumarate) will be presented. Polarization transfer to 13C
in these molecules by using adequate pulse sequences is demonstrated.
Moreover, constant NMR signal enhancement of 1H and 13C is shown using a
continuous delivery of parahydrogen by hollow fiber membranes. This
allows the acquisition of two-dimensional NMR experiments requiring
multiple excitations with constant initial polarization. The membrane
technique can be easily extended to produce a continuous flow of a
hyperpolarized liquid as will be shown for MRI applications.
All are welcome
A separate email will announce the 4pm talk
