The Lycurgus Cup, a world-renowned 4th-century A.D. artifact housed in the British Museum, is constructed of "dichroic" glass that shifts from jade green in reflected light to ruby red in transmitted light. This means that ...
When identical charges repel each other but are confined to the surface of a sphere, they seek the arrangement with the lowest possible energy. The idea is simple, but the problem gets harder to solve with every charge added. ...
Polymer brushes are dense layers of polymer chains that can be engineered to change how a surface interacts with its surroundings. By controlling interactions with water, ions, proteins and other materials, they can reduce ...
A new study led by an international research team including scientists at the University of South Carolina challenges the idea that the ancient Laacher See volcanic eruption in western Europe triggered a significant climate-cooling ...
Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. ...
Researchers at Umea university thought gold particles would make electronic components emit more light. Instead, they discovered an unexpected effect that could be important for the future of organic electronics.
As the climate gets warmer, the number of particles that make up clouds in the Arctic may increase or decrease, depending on the specific area. A new study indicates that the Arctic should be divided into three parts rather ...
Tiny atoms and molecules are constantly bombarding each other all around us. While we regularly measure the large-scale effects of these interactions, measuring the effect of each individual collision is far more difficult. ...
Transforming Mars into a more Earth-like world could irreversibly destroy scientific evidence about the planet's history and the possibility of extraterrestrial life. In an opinion article published in Eos, a team of Dutch, ...
They can turn up in a nonstick frying pan, a waterproof jacket, a takeout food wrapper or the foam used to fight fires. Known as "forever chemicals," these substances are ubiquitous in modern society, prized for their extreme ...
