Rare earth metals: Will we have enough?

Life in the 21st century wouldn't be the same without rare earth metals. Cell phones, iPads, laptops, televisions, hybrid cars, wind turbines, solar cells and many more products depend on rare earth metals to function. Will ...

New PV cell generates electricity from IR and UV light

(PhysOrg.com) -- A prototype of a new type of photovoltaic (PV) cell that generates electricity from visible, infrared and ultraviolet light has been demonstrated by a group of Japanese scientists. It could lead to the development ...

Neuron transistor behaves like a brain neuron

(Phys.org)—Researchers have built a new type of "neuron transistor"—a transistor that behaves like a neuron in a living brain. These devices could form the building blocks of neuromorphic hardware that may offer unprecedented ...

Direct imaging of active orbitals in quantum materials

In quantum materials based on transition metals, rare-earth and actinide elements, electronic states are characterized by electrons in orbitals d and f, combined with the solid's strong band formation. Until now, to estimate ...

New path forward for next-generation lithium-ion batteries

In the quest for a radically better lithium-ion battery, a promising direction is the so-called "lithium-rich" cathode, in which the cathode contains a higher proportion of lithium than normal. While it has the potential ...
