Dirac Nodal Line in Hourglass Semimetal Nb3SiTe6
Hourglass fermion in an electronic band structure is protected by the nonsymmorphic symmetry of a layered semimetal Nb3SiTe6. Angle-resolved photoemission spectroscopy demonstrates the band features of an hourglass fermion in k-space, such as band crossings and nodal loops. Read more »
The Donnan Potential, Revealed at Last
Researchers at the ALS recently led the first direct measurement of the Donnan potential, an electric potential that arises from an imbalance of charges at the interface of a charged membrane and a liquid. The work could yield new insights in areas such as ion transport through cellular membranes, ion exchange membranes in energy storage strategies, and water purification technologies. Read more »
2022 Highly Cited Researchers

Enhanced low-temperature proton conductivity in hydrogen-intercalated brownmillerite oxide
Solid oxide materials typically need high temperatures to allow appreciable ion transport, limiting their flexibility as electrolytes for energy devices. Lu et al. now show unusually high proton conductivity in a hydrogenated oxide between 40 °C and 140 °C, which they attribute to ordered vacancy channels and high proton concentrations. Read more »
Structural Investigation of Therapeutic Antibodies Using Hydroxyl Radical Protein Footprinting Methods
Well-known high-resolution structural methods are often used to characterize antibody structures, but many require specialized sample preparation that may perturb antibody structure. We describe here the relatively new method of hydroxyl radical protein footprinting, a solution-state method that can provide structural and kinetic information on antibodies or antibody–antigen interactions useful for therapeutic antibody design.

Gas-phase synthesis of racemic helicenes and their potential role in the enantiomeric enrichment of sugars and amino acids in meteorites
Molecular-beam experiments with isomer-selective photoionization via a targeted, vinylacetylene-mediated gas-phase reaction of aromatic helicenyl radicals coupled with electronic structure calculations and astrochemical modeling reveal an elegant synthetic route to racemic helicenes – ortho-fused polycyclic aromatic hydrocarbons (PAHs), in which benzene building blocks form helically-shaped molecules.

Uncompetitive, adduct-forming SARM1 inhibitors are neuroprotective in preclinical models of nerve injury and disease
Researchers describe potent small-molecule inhibitors that are neuroprotective in preclinical models of nerve injury and disease. The cover depicts the destruction of an axon by the enzyme SARM1, shown disproportionately large to convey its catastrophic role in driving degeneration once it is activated upon injury. Read more »
