Ring magnets for magnetic beads trapping in a capillary

Hubert Girault, Anne-Laure Gassner

This paper introduces the concept of ring magnets for magnetic beads (MBs) trapping in a capillary. Such magnets enable an easy insertion of a capillary simply like a pearl on a string. With this system, high magnetic forces are obtained thanks to the prox ...

Magnetic Stationary Phases for Protein Adsorption

Anne-Laure Gassner

Magnetic beads (MB) have now proven to be a powerful tool in both research and biomedical applications. They are available in a wide range of sizes (from nm to several µm) and their surface can be modified with molecules having biological specificities and ...

Transient Heat Transfer Model and Stability Analysis of helium-cooled Superconducting Cables

Luca Bottura, Pier Paolo Granieri, Panagiota Xydi

The stability is a key issue to design superconducting magnets and to ensure their proper exploitation. This is the case of the imminent operation of the Large Hadron Collider (LHC) accelerator, which requires a good knowledge of the stability margin of it ...
