An insect's ability to survive anaerobic conditions (without oxygen) during winter pupation occurs through periodic cycling of aerobic respiration pathways needed to recharge energy and clear waste. The cellular mechanisms at play during these brief near-arousal periods can provide clues to help improve the success in storage and transplant of human organs.
Comprised of two coils, each powered by a different subsystem of the Pulsed Field Facility’s 4 MJ Cap bank, this magnet provides users with fields up to 75 tesla.
A new type of MagLab user has emerged: A Data User – who accesses MagLab data from public data repositories to advance independent research goals. In this highlight, we feature Data Users working to develop software for improved identification of intact proteins by high resolution mass spectrometry (AKA - top-down proteomics). The original dataset was published in 2017 as a benchmark study on the performance of the 21T FT-ICR system for top-down proteomic analysis of colorectal cancer cells. It has since been cited in a poster and two papers for testing new data analysis algorithms and software packages, demonstrating the enhanced impact realized by of FAIR (Findable, Accessible, Interoperable, & Reusable) MagLab data.
Researchers share new insights on the role of seasonality in dissolved organic matter (DOM) composition in large Arctic rivers.
High-resolution electron magnetic resonance studies of the spin-wave spectrum in the high-field phase of the multiferroic Bismuth ferrite (BiFeO3) reveal direct evidence for the magnetoelastic coupling through a change in lattice symmetry from rhombohedral to monoclinic. This study provides important information for designing future spintronics devices based on BiFeO3.
A new method to study how the nuclei of atoms “communicate” with one another in the presence of unpaired electron spins has been developed at the MagLab. Known as hyperpolarization resurgence (HypRes), this method benefits and expands the application of a revolutionary technique known as dynamic nuclear polarization (DNP), which provides enormous signal enhancements in nuclear magnetic resonance (NMR) experiments.
This highlight focuses on the development of new thermometry required to study quantum materials and phenomena in high magnetic fields and at ultralow temperatures. The team has demonstrated that exceedingly small quartz tuning forks bathed in liquid 3He maintain a constant calibration that is magnetic field independent, thereby opening the use of these devices as new sensors of the response of quantum systems.
