A huge hydrogen generator at the Earth's core-mantle boundary

Splitting water into hydrogen and oxygen is a major theme in the development of clean, abundant energy source. A new study led by an international research group revealed that when water meets the iron core of the Earth, ...

An air-stable and waterproof lithium metal anode

Lithium metal anode offers a promising pathway to upgrade the energy density of lithium ion batteries for its high specific capacity (3800 mAh g-1) and low voltage (-3.04 V vs. Li/Li+). But the safety issues caused by dendrite ...

The world's first all-silicon laser

Integrated silicon photonics incorporates microelectronics and optoelectronics, a combination expected to revolutionize a variety of fields such as communication, sensing, lighting, displays, imaging and detection. Silicon ...

Researchers create single-crystal perovskite solar cells

Photovoltaic conversion is regarded as the ultimate solution to the growing demand for energy, yet traditional silicon-based solar cells are expensive to produce, and production itself involves intensive energy consumption. ...
