TITLE
Hyperpolarization
Researches with NV center, 129Xe and Parahydrogen
■ ABSTRACT
NMR (Nuclear Magnetic Resonance) has been
harnessed as the key spectroscopic technology in both industry and science
field. However, the high cost and effort of implementation and maintenance of
NMR/MRI (Magnetic Resonance Imaging) due to the difficulty in maintaining
strong magnetic field and cryogenic condition were the problematic even those
great advantages. The best way to overcome these drawbacks is to take advantage
of hyperpolarization effect that leads to the beyond the Boltzmann
distribution, allowing lowered demand for strong magnetic field. Dynamic
nuclear polarization (DNP) has been one of the most widely used method to
induce hyperpolarization on target materials. However, DNP exhibits low
efficiency and poor stability due to its harsh condition such as strong
magnetic field and cryogenic condition. Therefore, there has been much efforts
to induce hyperpolarization on targets using safe materials at room
temperature. Several promising tools (NV Center in diamond, 129Xe, and
parahydrogen) that can induce hyperpolarization in normal condition will be
introduced and discussed. Especially, parahydrogen system is currently set up
in Korea Military Academy and I will share some interesting results from it.
