Title: Innovations by Inventor Sami Jannin
Introduction
Sami Jannin is a notable inventor based in Lausanne, Switzerland. He has made significant contributions to the field of magnetic resonance through his innovative methods and devices. With a total of five patents to his name, Jannin's work is at the forefront of scientific advancements in hyperpolarization techniques.
Latest Patents
One of Jannin's latest patents is an MRI compatible method and device for rapid Dynamic Nuclear Polarization (DNP) on a solid-state hyperpolarized sample material. This method involves preparing a target material containing high gamma nuclei with a short T1, a polarizing agent with a broad Electron Paramagnetic Resonance (EPR) line, and low gamma nuclei with a long T1. The polarizing agent is irradiated with microwave radiation while the target material is at a cryogenic temperature and exposed to a static magnetic field of at least 4.0 T. This process polarizes the high gamma nuclei by DNP, and the polarization is subsequently transferred to the low gamma nuclei through Cross Polarization. Another significant patent is a method for hyperpolarization transfer in the liquid state, which includes steps for producing a hyperpolarized sample for magnetic resonance investigations. This method efficiently provides samples with hyperpolarized long T1 nuclei, particularly carbon or nitrogen.
