Used to perform complex chemical analysis, this magnet offers researchers the world's highest field for ion cyclotron resonance (ICR) mass spectrometry.
A recent high-field EPR study by MagLab users from Wayne State and Grand Valley State Universities has demonstrated that minor changes in the periphery of a nickel-containing molecule can lead to a dramatic reorganization of its electron distribution. This in turn, induces a major shift in the reactivity of this compound.
State-of-the-art ion cyclotron resonance magnet system offers researchers significantly more power and accuracy than ever before.
Ten years ago the 900 Ultra-Wide Bore magnet became available to an international user community for Nuclear Magnetic Resonance spectroscopy and Magnetic Resonance Imaging at the National High Magnetic Field Lab. Since then 69 publications have been published from this instrument spanning many disciplines and the number of publications per year continues to increase with 26 in just the past 18 months demonstrating that state of the art data continues to be collected on this superb magnet.
Paleobiogeochemist (no, that's not a typo) Nur Gueneli put some ancient dirt into our magnets to learn more about the Earth's earliest inhabitants.
MagLab users have employed a combination of ab-initio theory and a newly developed high-pressure, high-field ferromagnetic resonance technique, which is uniquely sensitive to anisotropic magnetic interactions, to gain insights into the importance of spin-orbit coupling effects in a range of organic materials where this effect is usually considered to be small. The findings may be applicable to topics as diverse as spintronics and topological spin phases.
An understanding of the formation mechanism of endohedral metallofullerenes may pave the way towards targeted synthesis of these nanomaterials, which are attractive for use in biomedicine and renewable energy. Their bottom-up synthesis is investigated and charge transfer from the encapsulated metal to carbon cage is determined to play a key role in formation.
Square-planar high-spin Fe(II) molecular compounds are rare. Using an easily modifiable pincer-type ligand, the successful synthesis of the first compound of this type that breaks the FeO4 motif was achieved, and the first spectroscopic evidence that the geometry and spin state persist in solution was obtained.
The explosion of the Deepwater Horizon oil rig in April 2012 resulted in the release of ~5 million barrels of crude oil into the Gulf of Mexico ecosystem, a fraction of which washed ashore onto Gulf beaches. We compare the detailed molecular analysis of hydrocarbons in oiled sands from Pensacola Beach to the Macondo wellhead oil (MWO) by Fourier transform ion cyclotron resonance mass spectrometry to identify major environmental transformation products of polar, high molecular weight petrogenic material from Pensacola Beach.
Targeted theranostic nanovehicles are capable of targeting cerebrovascular amyloid associated with Alzheimer’s Disease and serving as early diagnostic and therapeutic agents across multiple imaging modalities. Assessed in animal models at 21.1 T, these nanovehicles were loaded with gadolinium-based magnetic resonance imaging (MRI), iodine-based single photon emission computerized tomography (SPECT) or fluorescent contrast agents as well as anti-inflammatory and anti-amyloidogenic pharmaceuticals to demonstrate targeted enhancement and treatment in cerebral amyloid angiopathy.
