Nanoscale Metallic Particles Detected in Brain Tissue

Researchers detected nanoscale deposits of elemental copper and iron in brain tissues isolated from Alzheimer’s disease subjects. The discovery suggests new directions of study to determine the role that elemental metals might play in neurochemistry, neurobiology, and the development of neurodegenerative disease.

Chemical (and Strategic) Transformations at Beamline 9.0

The Chemical Dynamics beamline, used for gas-phase vacuum ultraviolet (VUV) experiments, was one of the first beamlines built at the ALS. Since then, the program has undergone several strategic transformations, enabling the study of complexity in clusters, aerosols, and nanoparticles using both VUV and soft x-ray radiation.

Main Attraction: Scientists Create World’s Thinnest Magnet

A one-atom-thin 2D magnet that operates at room temperature could lead to new applications in computing and electronics—such as high-density, compact spintronic memory devices—and new tools for the study of quantum physics. X-ray experiments at the ALS characterized the material’s magnetic parameters under high temperature. Read more »

Deconstructing the Infectious Machinery of the SARS-CoV-2 Virus

Scientists collaborated to model the complex protein responsible for SARS-CoV-2 replication, revealing its potential weak spots for drug development. The investigation hinged on data collected from many advanced imaging techniques, including small-angle x-ray scattering (SAXS), crystallography, and small-angle neutron scattering (SANS).

Mineral Microstructures Shed Light on Planet-Scale Dynamics

To explore what happens to minerals under the extreme conditions in Earth’s mantle, researchers developed an x-ray technique that bridges the gap between methods that reveal bulk properties and those that focus on individual crystals. Use of the technique has shed light on the dynamics of tectonic-plate subduction in Earth’s lower mantle. Read more »

Tuning Semimetallicity Using Thin Films and Interfaces

With support from ALS data, scientists gained new insight into a semimetal’s unusual electronic behavior. The work lays out a basic strategy for engineering the band structures of semimetallic compounds using dimensional confinement and reveals a new way of creating two-dimensional electron/hole gases by exploiting interfacial bonding.

Researchers Set Sights on Another COVID-19 Target

Early in the COVID-19 pandemic, it was quickly established that the receptor binding domain (RBD) of the SARS-CoV-2 spike protein is a prime target for neutralizing antibodies. Now, scientists have found a second region of the spike protein that is targeted by dozens of antibodies, some of which exhibit ultrapotent neutralizing activity. Read more »

Label-Free Characterization of Organic Nanocarriers

A technique developed at the ALS enables accurate characterization of organic nanocarriers (molecules that encapsulate other molecules) without the need for disruptive labeling. The method will enable faster, more precise development of exciting new technologies, ranging from targeted drug delivery to oil-spill remediation. Read more »PPT-icon-35 PDF-icon-35
