Flexible, semitransparent power source made with novel comb-teeth structure
Foldable display shows no crease after 100,000 folding cycles
Single molecule performs multiple logic operations simultaneously
Computing at the speed of light: Team takes big step toward much faster computers
University of Utah engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines.
Using quantum methods to read classical memories offers surprising advantages
Pentagon-backed 'time cloak' stops the clock (Update)
Pentagon-supported physicists on Wednesday said they had devised a "time cloak" that briefly makes an event undetectable.
Crystals ripple in response to light: First propagating surface phonon polaritons in a van der Waals crystal
Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to ...
Using light to control light: Engineers invent new device that could increase Internet download speeds
(Phys.org)—A team of scientists and engineers at the University of Minnesota has invented a unique microscale optical device that could greatly increase the speed of downloading information online and reduce ...
Groundbreaking optical device could enhance optical information processing, computers
At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. ...
Engineers develop a stretchable, foldable transparent electronic display (w/ Video)
(Phys.org) —Imagine an electronic display nearly as clear as a window, or a curtain that illuminates a room, or a smartphone screen that doubles in size, stretching like rubber. Now imagine all of these ...
Making a better invisibility cloak
The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ...
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Watching electrons move in topological insulators with femtosecond resolution
Topological insulators are exotic materials, discovered just a few years ago, that hold great promise for new kinds of electronic devices. The unusual behavior of electrons within them has been very difficult ...
All-optical magnetic switching promises terahertz-speed hard drive and RAM memory
(Phys.org) —Researchers at the Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used ...
