Gel-based audio speaker demonstrates capabilities of ionic conductors, long thought limited in application (w/ Video)
In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music—it's the "Morning" prelude from Peer Gynt, played on an ionic speaker.
Earliest known iron artifacts come from outer space
Researchers have shown that ancient Egyptian iron beads held at the UCL Petrie Museum were hammered from pieces of meteorites, rather than iron ore. The objects, which trace their origins to outer space, ...
Researchers discover way to allow 80 percent of sound to pass through walls
Researchers develop method to inkjet print highly conductive, bendable layers of graphene
(Phys.org) —Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.
Graphene 'onion rings' have delicious potential
Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.
Smart skin: Electronics that stick and stretch like a temporary tattoo (w/ video)
Engineers have developed a device platform that combines electronic components for sensing, medical diagnostics, communications and human-machine interfaces, all on an ultrathin skin-like patch that mounts ...
Multiple groups claim to create first atom-thick silicon sheets
(PhysOrg.com) -- Since its discovery in 2004, graphene -- sheets of carbon an atom thick -- has sparked a flurry of research into the nanomaterial's potential applications for blazing fast, tiny electronics. ...
Reliable 3-D memories from silicon oxide and graphene: Visionary transparent memory a step closer to reality
(Phys.org)—Researchers at Rice University are designing transparent, two-terminal, three-dimensional computer memories on flexible sheets that show promise for electronics and sophisticated heads-up displays.
Scientists make first direct images of topological insulator's edge currents
(Phys.org) —Researchers at a SLAC/Stanford institute have made the first direct images of electrical currents flowing along the edges of a topological insulator – a recently discovered state of matter ...
Shape-shifting sheets automatically fold into multiple shapes (w/ Video)
"More than meets the eye" may soon become more than just a tagline for a line of popular robotic toys. Researchers at Harvard and MIT have reshaped the landscape of programmable matter by devising self-folding ...

'Flying carpet': Princeton team's plastic sheet can hover above ground (w/ video)
New technique could mean super thin, strong graphene-based circuits
(Phys.org)—Integrated circuits, which are in everything from coffeemakers to computers and are patterned from perfectly crystalline silicon, are quite thin—but Cornell researchers think they can push ...
Physicists find right (and left) solution for on-chip optics
(Phys.org) —A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize ...
