Solid-Phase Polarization Matrixes for Dynamic Nuclear Polarization from Homogeneously Distributed Radicals in Mesostructured Hybrid Silica Materials

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli, David Benjamin Roger Antoine Gajan

Mesoporous hybrid silica-organic materials containing homogeneously distributed stable mono- or dinitroxide radicals covalently bound to the silica surface were developed as polarization matrixes for solid-state dynamic nuclear polarization (DNP) NMR exper ...

Methods for Molecular Magnetic Resonance Imaging and Magnetic Resonance Spectroscopy using Hyperpolarized Nuclei

Riccardo Balzan

Since the introduction 10 years ago of the dissolution method, Dynamic Nuclear Polarization (DNP) became a widely applied and powerful technique to enhance nuclear magnetic resonance (NMR) signals of low naturally abundant, insensitive nuclear spins for an ...

Polarization-selective optical nanostructures for optical MEMS integration

Hans Peter Herzig, Vincent Paeder

Optical nanostructures have the potential to provide useful new functionalities, using materials and fabrication methods that are compatible with standard silicon-based processes. For example, it has been shown that a nanoscale grating coated with a metal ...

Nonlinear emission properties of an optically anisotropic GaN-based microcavity

Nicolas Grandjean, Raphaël Butté, Jacques Levrat, Gatien Cosendey, Georg Rossbach, Marlene Glauser, Munise Nevin Cobet

The pronounced optical in-plane anisotropy of a suitably designed nonpolar GaN-based microcavity, mainly inherited from the valence-band complexity of wurtzite semiconductors, allows the coexistence of two different light-matter coupling regimes along orth ...

Some methods of dynamic nuclear polarization for use in metabolic imaging

Fiodar Kurdzesau

It has been suggested already more than 60 years ago to use polarized nuclei in particle scattering experiments1, but only with the discovery of the solid effect dynamic nuclear polarization process2 the realisation of polarized solid targets became possib ...

Infrared investigation of the phonon spectrum in the frustrated spin cluster compound FeTe2O5Cl

László Forró, Helmuth Berger

We present our optical investigations on the frustrated spin cluster compound FeTe2O5Cl, which develops a long-range antiferromagnetic order below 10 K. We measure the optical reflectivity from the far-infrared to the ultraviolet with polarized light. We f ...

Identification and characterization of proteins supporting dehalorespiration in Desulfitobacterium hafniense strain TCE1

Laure Prat

Respiration is a fundamental catalytic process in the aerobic and anaerobic energy metabolism of many prokaryotic and most eukaryotic organisms. The major difference between these organisms is that various organic and inorganic substrates can be used to do ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Solution NMR structure of a designed metalloprotein and complementary molecular dynamics refinement

Matteo Dal Peraro, Wei Liu

We report the solution NMR structure of a designed dimetal-binding protein, di-Zn(II) DFsc, along with a secondary refinement step employing molecular dynamics techniques. Calculation of the initial NMR structural ensemble by standard methods led to distor ...

Design and performance of a DNP prepolarizer coupled to a rodent MRI scanner

Rolf Gruetter, Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Fiodar Kurdzesau

For most of the last forty years, the techniques of Dynamic Nuclear Polarization (DNP) have been confined to particle-physics laboratories building polarized targets, but recently it has been shown that samples similar to a solid target can be transformed ...
