How Water Promotes Catalysis of Methane to Methanol August 3, 2020 - Researchers unraveled how water helps catalyze the conversion of methane, the main component of natural gas, into methanol, a liquid fuel. The work supports the efficient production of methanol and other useful chemicals and could help reduce the amount of greenhouse gases released by the flaring and venting of methane. Read more »
Rotavirus VP3 Is a Multifunctional Capping Machine August 3, 2020 - Rotavirus, a major cause of infantile gastroenteritis, is responsible for the deaths of about 200,000 children per year. Although vaccines are available, the virus still circulates, and a fuller understanding of the viral structures is needed. Here, scientists investigate the structure and function of the last unsolved rotavirus structural protein. Read more »
Artificial Antiferromagnets Facilitate Studies of Domain-Wall Motion July 30, 2020 - Researchers fabricated artificial spin lattices that undergo a paramagnetic-to-antiferromagnetic phase transition. These artificial antiferromagnets enable studies of dynamical properties that are critical to understanding, and ultimately implementing, real-world applications such as advanced computing and data-storage technologies.

COSMIC Probes Evolution of Single-Atom Platinum Catalyst July 24, 2020 - Researchers synthesized a single-atom platinum catalyst that outperformed, by a factor of 15, conventional platinum-based catalysts, which are used for fuel cells and automotive emissions control. Operando x-ray spectromicroscopy at the ALS’s COSMIC beamline revealed how electronic interactions affect the material’s morphology. Read more »
Antiferromagnet Transmits Coherent Spin Waves July 22, 2020 - Researchers discovered how pure spin currents (also known as spin waves) can be efficiently and coherently transmitted through an electrically insulating antiferromagnetic material. The work represents a notable milestone in the use of antiferromagnetic materials for low-power spintronic devices at room temperature. Read more » 
Antibody from SARS Survivor Neutralizes SARS-CoV-2 July 15, 2020 - Using structural data from the ALS and cryo-electron microscopy, researchers have characterized how an antibody binds to and neutralizes SARS-CoV-2. This work provides the basis for therapeutic and vaccine development for the SARS-CoV-2 virus, which is responsible for the COVID-19 pandemic. Read more » 
Long Chains Stabilize Higher-Efficiency Solar Cells June 19, 2020 - Perovskite thin films have many attractive properties for use in photovoltaics, but their assembly into practical devices has led to trade-offs between efficiency and stability. The addition of surfactant-type molecules with hydrophobic chains helped produce perovskite solar cells that are both efficient and stable. Read more »
Unexpected Rise in Ferroelectricity as Material Thins June 18, 2020 - Researchers showed that hafnium oxide surprisingly exhibits enhanced ferroelectricity (reversible electric polarization) as it gets thinner. The work shifts the focus of ferroelectric studies from more complex, problematic compounds to a simpler class of materials and opens the door to novel ultrasmall, energy-efficient electronics.
