Similarly, another high-entropy oxide, (Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)3O4, demonstrated remarkable lithium storage capabilities and stability over thousands of cycles, showcasing the advantages of ...

Unlike common lubricants that break down under high heat, spinel oxide maintains lubrication up to 700 degrees Celsius (1,292 degrees Fahrenheit) — that's nearly as hot as a metal forge. Enabling ...
