Researchers at Cornell University and Columbia University have developed a way to stack two-dimensional semiconductors and trap electrons in a repeating pattern that forms a specific and long-hypothesized crystal. The team also devised a new optical sensing technique that enabled them to observe numerous electron crystals with different crystal symmetries.

Scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory are using solid phase processing approaches to create materials with improved properties. Focusing on a lightweight aluminum silicon alloy widely used in the defense, aerospace, and automotive industries, the team used shear force to restructure the alloy at the nano-level. The distribution of the silicon was changed at the atomic level, making the microstructure much more robust than identical materials produced conventionally.

Physicists from the University of Wisconsin-Madison have observed reef-forming corals at the nanoscale and identified how they create their skeletons. The researchers used a spectromicroscopy technique to probe the growing skeletons, and results showed amorphous nanoparticles present in the coral tissue, at the growing surface, and in the region between the tissue and the skeleton. The results provide an explanation for how corals are resistant to acidifying oceans caused by rising carbon dioxide levels and suggest that controlling water temperature, not acidity, is crucial to mitigating loss and restoring reefs.

An international team of researchers has designed a highly sensitive nitric oxide and nitrogen dioxide sensor that can be implanted in the body. All of the components are biodegradable in water or in bodily fluids but remain functional enough to capture the information on the gas levels. The researchers made the device’s conductors out of magnesium and used nanoscale silicon for the functional materials.
