Weyl points in MoTe2
Ruling out Weyl points in MoTe2

Sometimes the hunt for new kinds of fundamental particles doesn't take place inside high-energy particle colliders, but rather in the low-energy degrees of freedom of exotic quantum materials.

Improving HOIP solar cells by controlling structural instabilities

Hybrid organic-inorganic perovskites (HOIPs) have become the most promising next generation solar cell material due to inexpensive processing and high efficiency.

Real-time observation of nanowire lithiation for energy storage

Lithium-ion batteries (LIBs) can store energy from alternative intermittent sources via chemical reactions, for later use in electronics, transportation, and grid load leveling.
