Magnetic teeth hold promise for materials and energy

A mollusk with teeth that can grind down rock may hold the key to making next generation abrasion-resistant materials and nanoscale materials for energy. The mollusk, called a gumboot chiton, scrapes algae off ocean rocks using a specialized set of teeth made from the magnetic mineral magnetite. The teeth have ...

Self-growing materials that strengthen in response to force

A strategy inspired by the process responsible for muscle growth could lead to the development of stronger, longer-lasting materials. Hokkaido University researchers have developed a strategy to fabricate materials that become stronger in response to mechanical stress — mimicking skeletal muscle growth. Their findings, published in the journal Science, could ...

Elusive Higgs-Like State Created in Exotic Materials

If you want to understand the personality of a material, study its electrons. Table salt forms cubic crystals because its atoms share electrons in that configuration; silver shines because its electrons absorb visible light and reradiate it back. Electron behavior causes nearly all material properties: hardness, conductivity, melting temperature. Quanta ...

Mantis shrimp inspires next generation of ultra-strong materials

Researchers at the University of California, Riverside and Purdue University are one step closer to developing super strong composite materials, thanks to the mantis shrimp, a small, multicolored marine crustacean that crushes the shells of its prey using a fist-like appendage called a dactyl club. Their latest research, to be ...

Light helps develop programmable materials

Light of a certain wavelength can be used to put so-called active materials into motion and control their movement. In the future, this discovery can become significant in widely different areas such as environmental protection, medicine and the development of new materials which can be programmed. Joakim Stenhammar at Lund ...

Lasers could rapidly make materials hotter than the Sun

Lasers could heat materials to temperatures hotter than the centre of the Sun in only 20 quadrillionths of a second, according to new research. Theoretical physicists from Imperial College London have devised an extremely rapid heating mechanism that they believe could heat certain materials to ten million degrees in much ...
