When plastic waste breaks down into the smallest fragments, less than 1 micrometer wide—or 1,000 times finer than human hair—it can’t be detected at wastewater treatment plants. But researchers have ...

The internal temperature of automobile driving motors rises to around 200 °C, which requires high residual magnetization and heat resistance. The coercivity of currently used neodymium-iron-boron ...

A magnetic powder that can rapidly suck out all the microplastics in water could be used by water treatment plants to better remove the contaminants. At present, most of these plants can remove only ...

Goudsmit Magnetics of Waalre, the Netherlands, has introduced a rotating magnetic separator designed for the ferrous-metal-free processing of lithium-ion powder intended for batteries. The company ...

Found in everything from wind turbines and electric cars to MRI machines and mobile phones, rare earth magnets are an essential part of the technology we depend on. That, plus their value, means there ...
