Magnets sustainably separate mixtures of rare earth metals

A new study describes a novel approach for purifying rare earth metals, crucial components of technology that require environmentally-damaging mining procedures. By relying on the metal's magnetic fields during the crystallization ...

Tomorrow's coolants of choice

Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating. Meanwhile, the increasing penetration of cooling applications into ...

On the way to printable organic light emitting diodes

Organic light-emitting diodes are components that no longer consist of compounds containing the semiconducting material gallium, but of so-called organic compounds in which carbon is a main component. Compared to conventional ...

New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds ...

Electric cars can clean up the mining industry – here's how

Growing demand for electric vehicles is important to help cut transport emissions, but it will also lead to new mining. Without a careful approach, we could create new environmental damage while trying to solve an environmental ...
