Simple procedure for the fabrication of flexible NMR shim coils

Autor: Jérôme Polesel-Maris, Vincent Martinez, Cedric Hugon, Xiaonan Li, Dimitrios Sakellariou

Publikováno v: Comptes Rendus Chimie. 16:967-971

Photolithography allows simple fabrication of flexible NMR shim coils. Here we demonstrate this procedure by fabricating optimized first-order shim coils for a transverse field orientation “Halbach” permanent magnet cylinder.

Publikováno v: Microporous and Mesoporous Materials. 178:79-83

A novel one-sided NMR magnet has been validated for accurate measurements of diffusion in thin samples. Results are presented from the measurement of self-diffusion in several solvents, including the room temperature ionic liquid 1-butyl-3-methyl imi

Permanent magnet assembly producing a strong tilted homogeneous magnetic field: towards magic angle field spinning NMR and MRI

Autor: Cedric Hugon, Sandrine Cazaux, Philippe Hardy, Angelo Guiga, Dimitrios Sakellariou, Guy Aubert

Publikováno v: Magnetic Resonance in Chemistry. 48:903-908

We introduce a cylindrical permanent magnet design that generates a homogeneous and strong magnetic field having an arbitrary inclination with respect to the axis of the cylinder. The analytical theory of 3 D magnetostatics has been applied to this p

Publikováno v: Microporous and Mesoporous Materials. 178:31-33

A Nuclear Magnetic Resonance (NMR) instrument providing a rotating field oriented at the magic angle with the rotation axis has the potential to record high resolution NMR spectra from static heterogeneous samples exhibiting susceptibility broadening

A Systematic Approach to the Design, Fabrication and Testing of Permanent Magnets Applied to Single-Sided NMR

Autor: Dimitris Sakellariou, Cedric Hugon, Guy Aubert

Publikováno v: AIP Conference Proceedings.

In this paper, we discuss the application of a systematic approach to magnet design to single‐sided magnets [1]. This approach, based on analytical expressions of the spherical harmonic expansion terms for basic magnet blocks allows to compute exac
