Because lithium is relatively scarce and sodium is abundant in Earth's crust, sodium-ion batteries are being investigated as viable, cost-effective alternatives to the widely used lithium-ion ...

In everyday life, we use many protective barriers: Sunscreen shields us from the sun, umbrellas keep us dry in the rain and oven mitts protect our hands from hot pans. Similarly, batteries need ...

As the world searches for alternatives to lithium-ion batteries, sodium-ion batteries are emerging as a promising solution.

Researchers develop a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a ...

In a significant breakthrough, astronomers have identified the presence of so-called “forbidden” elements in the Sun’s core.

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for ...

The divertor is one of the most core components in the fusion reactor used in the tokamak. It plays a vital role in ...

Scientists stabilize a sodium crystal structure, pushing solid-state batteries to perform at room and subzero temperatures.

Layered sodium manganese oxides (Na2/3MnO2) are promising cathode materials for developing high-capacity sodium-ion batteries. However, they suffer from severe capacity fading during cycling. In a new ...

The core goal of photovoltaic cells is to generate more electricity and reduce costs. Magnetron sputtering technology helps batteries break through efficiency bottlenecks by preparing key thin films.
