Moore than meets the eye
Photos of transistors.

Transistors replaced vacuum tubes in the mid-20th century. They were initially made of germanium and later silicon, leading to the development of integrated circuits containing millions to billions of transistors on a single chip. The Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) became the dominant type due to its smaller size, faster speed, and greater energy efficiency. Today, MOSFETs are essential components in modern electronic devices such as computers, smartphones, and power electronics.

Repairing fractured metals for more sustainable construction

Mining, refining, and processing metals commonly used in construction are estimated to contribute around three billion tons of CO2-equivalent emissions. Now, researchers have developed a new metal-healing technique that fully restores previously unrepairable metals, presenting sustainable options for manufacturers.
