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.

A Multiscale Picture of Oxygen Loss in Battery Electrodes

In lithium-ion batteries, oxygen atoms leak out of electrode particles as the lithium moves back and forth between electrodes. Now, researchers have measured this process at multiple length scales, showing how the oxygen loss changes the electrode’s structure and chemistry, gradually reducing the amount of energy it can store.

In a Hawaiian Lava Fountain, Fluid Magma Turns Brittle

Compared to the violent explosions of Mount Vesuvius or Mount St. Helens, Hawaiian volcanic eruptions are relatively calm, characterized by flowing rivers and fountains of lava. Here, researchers have discovered that even low-viscosity magma sometimes behaves more like brittle glass that shatters into fine particles. Read more »
