A Slowly Relaxing Rigid Biradical for Efficient Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy: Expeditious Characterization of Functional Group Manipulation in Hybrid Materials

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

A new nitroxide-based biradical having a long electron spin-lattice relaxation time (T-1e) has been developed as an exogenous polarization source for DNP solid-state NMR experiments. The performance of this new biradical is demonstrated on hybrid silica-ba ...

Ferroelectricity from spin supercurrents in LiCuVO4

Martin Mourigal, Mechthild Enderle

We have studied the magnetic structure of the ferroelectric frustrated spin-1/2 chain material LiCuVO4 in applied electric and magnetic fields using polarized neutrons. A symmetry and mean-field analysis of the data rules out the presence of static Dzyalos ...

A relationship between the dipolar and the chemical-shift scaling factors of cyclic radio-frequency irradiation schemes is introduced. This scaling factor theorem is derived analytically using Average Hamiltonian Theory, and its validity is illustrated num ...

The challenge of T1 contrast agents for high-magnetic field MRI

Lothar Helm

Magnetic resonance imaging (MRI) is one of the most powerful diagnostic techniques used in clinics. The need for higher spatial resoln. and better sensitivity led to the development of imagers working at high magnetic fields. The routine clin. use of 3 T M ...

Nested Surface Coils for Multinuclear NMR

Rolf Gruetter

This article introduces the design of surface coils for multinuclear applications. The relative sensitivities of several NMR-visible nuclei of biological interest are considered, and the motivations to operate an RF coil at multiple frequencies, both seque ...

Probing surface site heterogeneity through 1D and INADEQUATE P-31 solid state NMR spectroscopy of silica supported PMe3-Au(I) adducts

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

Grafting of (Me3Si)(2)N-AuPMe3 on SiO2-(700) leads to the formation of [( SiO)Au-PMe3] located in different surface environments due to the presence or absence of adjacent siloxane bridges, as shown both by P-31 solid state NMR and by its conversion into a ...

ROYAL SOC CHEMISTRY2011

Relaxation processes induced by the antisymmetric part of the chemical shift anisotropy tensor (henceforth called anti-CSA) are usually neglected in NMR relaxation studies. It is shown here that anti-CSA components contribute to longitudinal relaxation rat ...

Dynamic Actuation of Magnetic Beads for Immunoassays on-chip

Yves Moser

This thesis was carried out in the frame of the European project DetectHIV aiming the development of a new biosensor platform for the highly sensitive detection of the HIV capsid protein p24. We explore the implementation of a magnetic bead-based lab-on-a- ...

Solid-state nitrogen-14 nuclear magnetic resonance enhanced by dynamic nuclear polarization using a gyrotron

Geoffrey Bodenhausen, Marc Anthony Caporini

By combining indirect detection of N-14 with dynamic nuclear polarization (DNP) using a gyrotron, the signal-to-noise ratio can be dramatically improved and the recovery delay between subsequent experiments can be shortened. Spectra of glassy samples of th ...

MP2RAGE, a self bias-field corrected sequence for improved segmentation and T-1-mapping at high field

Rolf Gruetter, Tobias Kober, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

The large spatial inhomogeneity in transmit B, field (B-1(+)) observable in human MR images at hi h static magnetic fields (B-0) severely impairs image quality. To overcome this effect in brain T-1-weighted images the, MPRAGE sequence was modified to gener ...
