Spatial Contributions to Nuclear Magnetic Shieldings [PDF]
The Journal of Physical Chemistry A, 2021 We develop a methodology for calculating, analyzing, and visualizing nuclear magnetic shielding densities which are calculated from the current density via the Biot–Savart relation. Atomic contributions to nuclear magnetic shielding constants can be estimated within our framework with a Becke partitioning scheme.

A lightweight magnetically shielded room with active shielding
Scientific Reports, 2022 AbstractMagnetically shielded rooms (MSRs) use multiple layers of materials such as MuMetal to screen external magnetic fields that would otherwise interfere with high precision magnetic field measurements such as magnetoencephalography (MEG). Optically pumped magnetometers (OPMs) have enabled the development of wearable MEG systems which have the ...
