Salty surprise: Ordinary table salt turns into 'forbidden' forms
High-pressure experiments with ordinary table salt have produced new chemical compounds that should not exist according to the textbook rules of chemistry. The study at DESY's X-ray source PETRA III and at ...
Color-tunable photonic fibers mimic the fruit of the 'bastard hogberry' plant
(Phys.org)—A team of materials scientists at Harvard University and the University of Exeter, UK, have invented a new fiber that changes color when stretched. Inspired by nature, the researchers identified ...
High-energy X-rays shine light on mystery of Picasso's paints
(Phys.org)—The Art Institute of Chicago teamed up with Argonne National Laboratory to help unravel a decades-long debate among art scholars about what kind of paint Picasso used to create his masterpieces.

'Look Mom No Electricity': Transmitting Information with Chemistry
Rust never sleeps—Observations of electron hopping in iron oxide hold consequences for environment and energy
(Phys.org)—Rust—iron oxide—is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to ...
Molecule's carbon chain length affects oxygen's departure in key reaction for building bio-fuels
(Phys.org) —In a maze of blindingly complex reactions that snap oxygen atoms off cellulose or other bio-sources to create energy-dense fuel, the starting molecule's size has a curious effect. If the oxygen-rich ...
Understanding photosynthesis: How plants use catalytic reactions to split oxygen from water
Splitting hydrogen and oxygen from water using conventional electrolysis techniques requires considerable amounts of electrical energy. But green plants produce oxygen from water efficiently using a catalytic ...
