The online magazine Physics World has awarded the research team of Pablo Jarillo-Herrero, a researcher of the MIT, for making a discovery that led to the development of “twistronics”. This promising technique can adjust the electronic properties of graphene by rotation of its adjacent layers. Their first achievement was the creation of magic-angle graphene, which behaves like a high temperature semiconductor.

Branched nanoparticles are one of the most promising catalysts.
Scientists can control their branch sizes and surfaces to make them more stable and more effective catalysts.
Metalenses are ultrathin, flat surfaces that use nanostructures to focus light. They have attracted tremendous attention because they can overcome limitations of conventional bulky, curved and heavy refractive optical lenses and they are poised to revolutionize everything from microscopy to cameras, sensors, and displays.
