Published Atom-thin walls could smash size, memory barriers in next-gen devices
(via sciencedaily.com) For all of the still-indistinguishable-from-magic wizardry packed into the three pounds of the adult human brain, it obeys the same rule as the other living tissue it controls: Oxygen is a must. So it was with a touch of irony that a scientists offered his explanation for a technological wonder -- movable, data-covered walls mere atoms wide -- that may eventually help computers behave more like a brain. 'There was unambiguous evidence that oxygen vacancies are responsible for this,' Tsymbal said.
Published Chiral phonons create spin current without needing magnetic materials
(via sciencedaily.com) Researchers chiral phonons to convert wasted heat into spin information -- without needing magnetic materials. The finding could lead to new classes of less expensive, energy-efficient spintronic devices for use in applications ranging from computational memory to power grids.
