Read moreScientists have proposed a new communications scheme that would use silicon wires carrying a constant current to drive electrons from a transmitter to a receiver. By changing its magnetization, a contact would inject electron spin (either up or down) into the current at the transmitter end.

Read moreA remarkable effect never witnessed before has been discovered in the ring-shaped stains of tiny dissolved particles ('coffee stains') that develop after a liquid has evaporated. While the particles on the outside of the ring are neatly organized, chaos reigns on the inside of the ring where the particles seem to have collected in a great hurry.

Read moreAn amorphous-seed mediated strategy has been developed in the Center for Nanoscale Materials Nanophotonics Group for creating bifunctional nanoparticles composed of silver and iron oxide nanodomains. These hybrid particles exhibit unique optical properties due to surface plasmon resonance from the silver and superparamagnetic responses from the iron oxide.

Read moreA European team of researchers has discovered that properties of the so-called topological insulator bismuth selenide could provide the solution to how a ground-breaking new computing technology called 'spintronics' can work at room temperature. This is a solution scientists have been waiting for ever since the technology was predicted more than two decades ago.

Read moreOne of the most serious personnel shortages in the global science and engineering workforce - numbering more than 20 million in the United States alone - involves a scarcity of real-life versions of Superman, Superwoman and other superheroes and superheroines with charm, charisma, people skills and communication skills. That's the premise behind an unusual symposium occurring here today at the 242nd National Meeting and Exposition of the American Chemical Society.
