Title: Innovations of James G Kempf
Introduction
James G Kempf is a notable inventor based in Arlington, MA (US). He has made significant contributions to the field of nuclear spin hyperpolarization, holding a total of 3 patents. His work has advanced the understanding and application of magnetic resonance measurements.
Latest Patents
Kempf's latest patents include a method for enhancing nuclear spin polarization in a porous matrix. This innovative approach utilizes a hyperpolarized source material that is co-confined with target molecules in a porous molecular matrix. The matrix may consist of a D4R-polysiloxane copolymer, such as polyoligosiloxysilicone number two (PSS-2), which has recesses of an appropriate diameter. By transferring a source material, such as parahydrogen, into the matrix along with the target molecules, and applying external pressure, the spin polarization transfer from the source material to the target molecules is enhanced. This process significantly improves the signal strength of the target molecules in subsequent magnetic resonance measurements.
Another notable patent by Kempf is a sample introduction system and method for polarization. This system features an input stage designed to receive a sample molecule carrier and cool it from a first temperature to a second temperature as it travels along the input stage. The system also includes a closed volume that holds multiple sample molecule carriers in a high magnetic field created by an adjacent magnet, facilitating efficient output from the closed volume.
