Magnets—Print, power, repeat

Oak Ridge National Laboratory scientists have improved a mixture of materials used to 3D print permanent magnets with increased density, which could yield longer lasting, better performing magnets for electric motors, sensors and vehicle applications.

Used cooking oil can be converted into biofuel with carbon derived from recycled tires—a new method developed by an Oak Ridge National Laboratory-led research team.

Materials – Cooking up biofuel

Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory-led research team has developed a simple method to convert used cooking oil into biofuel.
Discarded tires can provide material useful for lower-cost sodium-ion batteries for energy storage.

Batteries – New life for old tires

Hard carbon materials recycled from tires continue to show great promise as anodes in sodium-ion batteries for large-scale energy storage, according to an Oak Ridge National Laboratory study led by Yunchao Li.
