These monthly highlights, selected by MagLab Director Greg Boebinger, represent the most promising and cutting-edge research underway in the lab’s seven user facilities.
Pulsed magnets are designed to operate near their structural limits to be able to generate extremely high magnetic fields. The coils have a limited life expectancy and thus need to be replaced on occasion. Fabrication of these large coils are now being done at the MagLab where advanced nondestructive examinations can be performed. Because of more rigorous quality controls and improvements in high-strength conductors and reinforcement materials, the lifetime of these coils can be extended.
With advanced techniques and world-record magnetic fields, researchers have detected new MRI signals from brain tumors.
Combining high-field NMR with infrared microscopy, scientists learned more about how gas diffuses in a novel class of molecular sieves that could one day be used for gas separation.
Scientists will be able to apply the technique to characterize similar molecules, helping develop vaccines and drugs to treat bacterial infection.
Scientists revealed previously unobserved and unexpected FQH states in monolayer graphene that raise new questions regarding the interaction between electrons in these states.
Insights into the structure and movement of T cell surface proteins could lead to new ways to fight cancers, infections and other diseases.
With unprecedented sensitivity and resolution from state-of-the-art magnets, scientists have identified for the first time the cell wall structure of one of the most prevalent and deadly fungi.
Scientists have long pursued the goal of superconductivity at room temperature. This work opens a route towards one day stabilizing superconductivity at room temperature, which could open tremendous technological opportunities.
Researchers have discovered a new method to create encapsulated carbon nanomaterials that contain fluorine. Known as fullerenes, these nanocages are promising candidates for clean energy applications.
Scientists found that the emergence of an exotic quantum mechanical phase in Ce1-xNdxCoIn5 is due to a shape change in the Fermi surface. This finding ran counter to theoretical arguments and has led investigators in new directions.
Weyl metals such as tantalum arsenide (TaAs) are predicted to have novel properties arising from a chirality of their electron spins. Scientists induced an imbalance between the left- and right-handed spin states, resulting in a topologically protected current. This was the first time this phenomenon, known as the chiral anomaly, has been observed.
This research established experimental evidence for the long sought-after transition of a small, two-dimensional sheet of electrons to a solid state.
This work investigates a series of oxoiron complexes that serve as models towards understanding the mechanism of catalysis for certain iron-containing enzymes.
Molecular fossils of chlorophyll (called porphyrins) more than 1.1 billion years old find suggest that photosynthesis began 600 million years earlier than previously established.
A new pH sensitive contrast agent for MR imaging has been developed that produces image contrast based on the local pH and that has great potential for use in living animals and medical diagnostics.
The causes of migraines are not well understood, with treatment limited to addressing pain rather than its origin. Research conducted with hydrogen MRI is attempting to identify the "migraine generator."
This work provides important insight into one of the parent materials of iron-based superconductors.
Scientists used high magnetic fields and low temperatures to study crystals of URu2–xFexSi2. Using these conditions, they explored an intriguing state of matter called the "hidden order phase" that exhibits emergent behavior. Emergent behavior occurs when the whole is greater than the sum of its parts, meaning the whole has exciting properties that its parts do not possess; it is an important concept in philosophy, the brain and theories of life. This data provide strict constraints on theories of emergent behavior.
Recent measurements of superconducting tapes in the MagLab's 45-tesla hybrid magnet shows that the power function dependence of current on magnetic field remains valid up to 45T in liquid helium, while for magnetic field in the plane of the tape conductor, almost no magnetic field dependence is observed. Thus design of ultra-high-field magnets capable of reaching 50T and higher is feasible using the latest high-critical current density REBCO tape.
Scientists measured the first in vivo images of stimulated current within the brain using an imaging method that may improve reproducibility and safety, and help understand the mechanisms of action of electrical stimulation.
