Imaging Sequences for Hyperpolarized Solids
Molecules, 2020 Hyperpolarization is one of the approaches to enhance Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) signal by increasing the population difference between the nuclear spin states.

Accurate structural correlations from maximum likelihood superpositions. [PDF]
PLoS Computational Biology, 2008 The cores of globular proteins are densely packed, resulting in complicated networks of structural interactions. These interactions in turn give rise to dynamic structural correlations over a wide range of time scales.

Mixed-valence compounds as polarizing agents for Overhauser dynamic nuclear polarization in solids [PDF]
arXiv, 2021 In this paper we investigate a novel set of polarizing agents -- mixed-valence compounds -- by theoretical and experimental methods and demonstrate their performance in high-field Dynamic Nuclear Polarization (DNP) experiments in the solid state. Mixed-valence compounds constitute a group of molecules, in which molecular mobility persists even in ...

Nuclear magnetic resonance spectroscopy as a dynamical structural probe of high pressure hydrogen [PDF]
Phys. Rev. Lett. 122, 135501 (2019), 2019 An unambiguous crystallographic structure solution for the observed phases II-VI of high pressure hydrogen does not exist due to the failure of standard structural probes at extreme pressure. In this work we propose that nuclear magnetic resonance spectroscopy provides a complementary structural probe for high pressure hydrogen.

Spin polarization contrast observed in GaAs by force-detected nuclear magnetic resonance [PDF]
Appl. Phys. Lett. 80, 1794 (2002), 2002 We applied the recently developed technique of force-detected nuclear magnetic resonance (NMR) to observe 71Ga, 69Ga, and 75As in GaAs. The nuclear spin-lattice relaxation time is 21$\pm$5 min for 69Ga at $\sim 5$ K and 4.6 Tesla. We have exploited this long relaxation time to first create and then observe spatially varying nuclear spin polarization ...

Dynamical Response of Nanomechanical Resonators to Biomolecular Interactions [PDF]
, 2007 We studied the dynamical response of a nanomechanical resonator to biomolecular (e.g. DNA) adsorptions on a resonator's surface by using a theoretical model, which considers the Hamiltonian H such that the potential energy consists of elastic bending energy of a resonator and the potential energy for biomolecular interactions.

Probabilistic interaction network of evidence algorithm and its application to complete labeling of peak lists from protein NMR spectroscopy. [PDF]
PLoS Computational Biology, 2009 The process of assigning a finite set of tags or labels to a collection of observations, subject to side conditions, is notable for its computational complexity.
