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.
Triple point: Physicists pinpoint key property of material that both conducts and insulates
It is well known to scientists that the three common phases of water – ice, liquid and vapor – can exist stably together only at a particular temperature and pressure, called the triple point.
Material turns 'schizophrenic' on way to superconductivity
(Phys.org) —Rice University physicists on the hunt for the origins of high-temperature superconductivity have published new findings this week about a material that becomes "schizophrenic"—simultaneously ...
Researchers create highly conductive and elastic conductors using silver nanowires
Researchers from North Carolina State University have developed highly conductive and elastic conductors made from silver nanoscale wires (nanowires). These elastic conductors could be used to develop stretchable ...
'Nanocable' could be big boon for energy storage
Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported ...
Reversible doping: Hydrogen flips switch on vanadium oxide
If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks ...
Researchers find possible evidence of Majorana fermions
Pair claim they have turned hydrogen to metal
High-voltage engineers create nearly 200-foot-long electrical arcs using less energy than before (Update)
Photos taken by the researchers show plasma arcs up to 60 meters long casting an eerie blue glow over buildings and trees at the High Voltage Laboratory at the University of Canterbury in New Zealand.
Chandra finds superfluid in neutron star's core
(PhysOrg.com) -- NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in ...
Demonstration electric car draws energy from the road
New transparent insulating film could enable energy-efficient displays
Johns Hopkins materials scientists have found a new use for a chemical compound that has traditionally been viewed as an electrical conductor, a substance that allows electricity to flow through it. By orienting ...
Kirigami art could enable stretchable plasma screens
The art of paper cutting may slice through a roadblock on the way to flexible, stretchable electronics, a team of engineers and an artist at the University of Michigan has found.
From metal to insulator and back again
New work from Carnegie's Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Re ...
