Heart-powered pacemaker could one day eliminate battery-replacement surgery
A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves.
New record voltage for organic solar cells opens the tech to consumer electronics
Molecular Solar Ltd, a spinout company from the University of Warwick, has achieved a significant breakthrough in the performance of solar photovoltaic (PV) cells. They have achieved and demonstrated a record ...
Increasing processor efficiency by 'shutting off the lights'
There was a time when a laptop could weigh 10 pounds and still sella time when a cell phone was larger than a pocketand a time when an iPod only played music.
'Voltage Patterning' could be next step in nanostructure lithography
Chameleon magnets: ability to switch magnets 'on' or 'off' could revolutionize computing
(PhysOrg.com) -- What causes a magnet to be a magnet, and how can we control a magnet's behavior? These are the questions that University at Buffalo researcher Igor Zutic, a theoretical physicist, has been ...
Lightning really does make mushrooms multiply
Off-grid German village banks on wind, sun, pig manure
If Germany has taken a pioneering though risky role in shifting to renewable energy, then the tiny village of Feldheim—population 150—is at its vanguard.
A single-sheet graphene p-n junction with two top gates
Researchers in Canada have designed and fabricated a single-sheet graphene p-n junction with two top gates. The standard technique, using a top and a bottom gate, can lead to damaging of the graphene layer. ...
Researchers develop battery-less chemical detector
(PhysOrg.com) -- Unlike many conventional chemical detectors that require an external power source, Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires, rather ...
Certain doped-oxide ceramics resist Ohm's Law
For months, Anthony West could hardly believe what he and his colleagues were seeing in the lab -- or the only explanation for the unexpected phenomena that seemed to make sense.
Mobile phones come alive with the sound of music, thanks to nanogenerators
Charging mobile phones with sound, like chants from at football ground, could become a reality, according to a new collaboration between scientists from Queen Mary University of London and Nokia.
