Both rubies and emeralds are minerals, which is a type of rock with a consistent chemical composition and a highly ordered ...

Scientists have developed a groundbreaking material that barely changes size with temperature, defying the usual expansion of ...

Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The discovery provides essential data for ...

The only way to eliminate the threat of nuclear-armed missiles is to negotiate their elimination—not pretend some magic ...

Rubies and emeralds have the colors they do because, like many substances, they absorb some colors of light. Most visible light, like sunlight, is composed of all the colors of the rainbow: red, ...

Grid energy storage is one of the hottest areas of research and engineering today. It's all about cheap, sustainable, and efficient materials, which makes iron-air batteries stand out amongst the ...

A novel iron-based catalyst with an inverse structure significantly outperforms traditional catalysts in ammonia production, ...

Most materials expand when they get warm. Researchers have now succeeded in developing a metal alloy that practically does ...

Iron-rich rocks tend to drive reactions that ... by letting the conditions underground do the hard work in powering chemical reactions that transform hydrogen and nitrogen into ammonia.

“While previous studies mostly focus on original system design and numerical simulation, we report a rational and universal ...

The novel iron-based catalyst exhibits superior performance for ammonia (NH3) synthesis compared to a well-established, century-old counterpart. By designing this new catalyst with an inverse ...
