Phys.org / New research shows how 'hot electrons' can reshape metals in billionths of a second
Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior.
Tech Xplore / Can AI's power problem become a clean-energy opportunity?
Artificial intelligence has triggered a new gold rush. This time, companies are competing not for land or minerals, but for access to electricity.
Phys.org / Christmas in July: Engineers capture gigapixel 3D video of snowflakes
For the first time, researchers can witness nanometer-scale thickness changes across a melting snowflake with a compact, lensless chip that captures gigapixel video at 30 frames per second across centimeter-scale fields.
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Tech Xplore / Seed crystals push solvent‑free perovskite cells to 25.53% efficiency
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are helping to reduce reliance on electricity generated from fossil fuels. While most solar cells used today ...
Tech Xplore / Tiny memory switches could shrink 5G and 6G radio-frequency chips
Mobile phones today handle far more wireless signals and services than earlier generations. The same is true of the sophisticated equipment behind mobile networks, such as base stations, and emerging technologies such as ...
Phys.org / There's a business case for companies to embrace sustainability, if it's pitched the right way
Sustainable business practices are often seen as a luxury that only rich countries can afford. And these days, some of the biggest economies, including the U.S., are backtracking on those commitments.
Phys.org / Melts in your mouth, but not in your car: The ongoing scientific quest to create heat‑resistant chocolate
There are few pleasures greater than letting a piece of chocolate melt slowly on your tongue. Indeed, the proximity of chocolate's melting point to our own body temperature is one reason it is so widely appreciated.
Tech Xplore / Prototype device polarizes light with heat for denser optical signals
Researchers have found a way to speed up components that control light polarization in optical communication and computing. Polarization is a property of light that can carry additional information along with the primary ...
Tech Xplore / Elephant-inspired cement tiles cool buildings without electricity
Inspired by the cracked, water-trapping skin of elephants, Penn researchers have developed a low-cost cement tile that cools buildings by capturing and slowly evaporating water—turning a structural flaw into a climate solution.
Phys.org / Vapor-controlled supramolecules can switch color, glow and phase
Controlling interactions between molecules and their functions from the molecular level to the macroscopic scale is challenging in supramolecular and materials chemistry. To this end, a research team led by associate professor ...
Phys.org / Frozen fiber couples light and sound 1,000 times more strongly than standard glass fibers
Researchers have developed a new type of optical fiber by freezing a glass capillary filled with liquid. It guides light and sound waves simultaneously and enables highly efficient coupling between them. The high coupling ...
