Lithium ions traveling through a zinc antimonide anode cause local stress and phase transitions, a process dubbed atomic shuffling. These changes may help explain why most anodes made of layered materials eventually fail.
Scientists designed a new nanostructure that absorbs ultranarrow bands of light spectrum and can be used in a number of applications, including the creation of more sensitive biosensors.
Inspired by wounded warriors, new paint-on, see-through bandage not only protects wounds and severe burns but enables direct measurement of tissue oxygenation.
Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine's unique stealthy nanoparticles.
Using mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments - a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules.
