Limitation exposed in promising quantum computing material

Quantum computers promise to perform operations of great importance believed to be impossible for our technology today. Current computers process information via transistors carrying one of two units of information, either ...

New class of solar cells, using lead-free perovskite materials

Lead-based perovskites are promising materials for low-cost and high-efficiency solar cells. However, the intrinsic instability and the toxicity of lead (Pb) have raised serious concerns of the viability of Pb-based perovskites, ...

NASA catches the scattered remains of former Tropical Storm Tara

NASA's Aqua satellite captured an infrared image of the remnants of former Tropical Storm Tara after it dissipated near the coast of western Mexico's Jalisco state. Jalisco is a western Mexican state along the Eastern Pacific ...

Spin-polarized surface states in superconductors

When it comes to entirely new, faster, more powerful computers, Majorana fermions may be the answer. These hypothetical particles can do a better job than conventional quantum bits (qubits) of light or matter. Why? Because ...
