    Sudden breakups of monogamous quantum couples surprise researchers

    January 5, 2026, Categories  Physics, Technology/Electronics

    two layers of a chemical structure lie above each other with black balls hovering on top. On the top layer, there is a cyan ball with a white ball in the corresponding layer below
    An exciton forms when an electron pairs up with a hole—a mobile particle-like void in a material where an electron is missing from an atom. When paired up as an exciton, a hole and electron normally travel around together as an exclusive couple, but a new experiment probes what happens when conditions in a material break up the pair. In the image, a hole (grey sphere) resides in the bottom layer of a stacked material and is paired to an electron in the top layer (cyan sphere). None of the electrons present in the top layer (black spheres) are willing to share a spot in the material with each other or the electron in the exciton. (Credit: Mahmoud Jalali Mehrabad/JQI)

    Tiny tech, big AI power: What are 2-nanometer chips?

    January 3, 2026, Categories  Physics, Technology/Electronics

    Only a few companies are able to produce 2-nanometre chips, including Taiwan's TSMC, which dominates the industry
    Only a few companies are able to produce 2-nanometer chips, including Taiwan’s TSMC, which dominates the industry.

    Taiwan’s world-leading microchip manufacturer TSMC says it has started mass producing next-generation “2-nanometer” chips.

    AFP looks at what that means, and why it’s important:

    What can they do?
    The computing power of chips has increased dramatically over the decades as makers cram them with more microscopic electronic components.

    That has brought huge technological leaps to everything from smartphones to cars, as well as the advent of artificial intelligence tools like ChatGPT.

    Advanced 2-nanometer (2nm) chips perform better and are more energy-efficient than past types, and are structured differently to house even more of the key components known as transistor...

    A research team affiliated with UNIST has introduced a technology that generates electricity from raindrops striking rooftops, offering a self-powered approach to automated drainage control and flood warning during heavy rainfall.

    Led by Professor Young-Bin Park of the Department of Mechanical Engineering at UNIST, the team developed a droplet-based electricity generator (DEG) using carbon fiber-reinforced polymer (CFRP). This device, called the superhydrophobic fiber-reinforced polymer (S-FRP-DEG), converts the impact of falling rain into electrical signals capable of operating stormwater management systems without an external power source...
