MagLab at Argonne
The National High Magnetic Field Laboratory (MagLab) presents a special MagLab at Argonne Day Monday, April 8, 2013, from 8:45 a.m. to 4:00 p.m. in Building 402, Rooms E1100 and E1200.
The day will feature presentations that highlight the research performed at MagLab. Topics and fields of research range from energy storage to electon magnetic resonance. View the agenda below.
8:45 a.m. Welcoming Remarks
9:00 a.m. Energy Storage
Presenter: Albert Migliori
Electrochemical electrical energy: Modification of electrocatalyst electronic structure during catalysis to explore the way catalysts work and how to improve them. Li imaging via NMR and more in situ in batteries. Electronic structure via quantum oscillations and cyclotron resonance for metals used in energy storage and conversion.
Special purpose nuclear reactors: Electronic structure of metallic fission fuels such as UN and more. Engineered systems to include micro pumped hydroelectric energy storage and water-to-air heat exchanges for solar thermal.
Grid stability and optimization: The potential to test devices and systems at grid power levels without actually disrupting the grid using the MagLab/LANL 1.4GW generator may be absolutely unique.
9:30 a.m. Ion Cyclotron Resonance
Presenter: Alan Marshall
Petroleomics: Correlation and Prediction of the Properties and Behavior of Petroleum Crude Oil and Its Products from Comprehensive Chemical Composition of Its Constituents.
Applications: Oil/Water Emulsion Stability Prediction; Identification of Deposits Before they Form in Pipes; Oil Spill Identification and Evolution; Biofuels.
Biological Applications of Ultrahigh-Resolution Mass Spectrometry: Top-Down Proteomics to Identify and Quantitate Proteins and their Post-Translational Chemical Modifications.
Mapping Contact Surfaces in Ligand and Protein: Protein Complexes by Solution-Phase Hydrogen/Deuterium Exchange Monitored by FT-ICR Mass Spectrometry.
10:00 a.m. Nuclear Magnet Resonance and Magnetic Resonance Imaging
Presenter: Lucio Frydman
Magnetic Resonance Opportunities: These include magnetic resonance investigations on battery-oriented material, solid state NMR on polymers with potential applications in reversed osmosis, studies on membrane-bound proteins of the kind involved in a number of photosynthetic processes.
Beyond conventional NMR and MRI analyses: High-field 600 MHz solid state DNP NMR facility -which could eventually be endowed with microimaging capabilities. The advent of a 36 T hybrid magnet system with ppm resolution and stability, capable of implementing solid state NMR of insensitive nuclei.
10:30 a.m. Break
11:00 a.m. Electron Magnetic Resonance
Presenter: Steve Hill
Catalysis: Many catalytic processes involve paramagnetic species such as radicals or transition metal ions that undergo changes in oxidation state (i.e. spin) during the reaction cycle. The very high-fields and frequencies available for EPR at the MagLab enable studies of catalytic reactions with improved sensitivity and resolution (i.e. ability to resolve different reaction products).
Carbon-based Photovoltaics: Organic spins are characterized by weak spin-orbit coupling, resulting in very little g-factor anisotropy. Yet this anisotropy is a property of considerable structural diagnostic value. As such, it can provide crucial knowledge for understanding functionality. The MagLab high-homogeneity high-field magnets coupled to expertise in high-frequency EPR enables resolution of unprecedentedly small g-anisotropies.
Hard Ferromagnets: The EPR/FMR techniques provide a direct measure of magnetic anisotropy. Ferromagnetic resonance (FMR) excitations are often inaccessible using commercial spectrometers for the hardest (most anisotropic) magnetic materials. However, this is not the case a the MagLab, which provides access to frequencies and fields that exceed commercial instruments by more than an order of magnitude.
11:30 a.m. Magnet Technology
Presenter: Mark Bird
25T – 40T magnets for x-ray scattering: Conceptual design of pulsed and dc magnets with field ranging from 25 T dc to 40 T pulsed will be presented. The dc work is based on the technology being developed for the 32 T all-superconducting magnet using YBCO tape for the innermost coils. The magnet will be installed at the MagLab as the world’s first user facility using High Temperature Superconductors (HTS).
The MagLab has performed a design study developing concepts of split and conical magnets in the range of 25 – 30 T using similar technology. Superconducting DC Split magnets making 25 T that are of similar size to the existing 16 T split magnet at SNS appear to be possible. The pulsed work is based on a collaboration between the MagLab and the APS that has produced the “hourglass” concept that enables diffraction studies.
