Using millions of tiny fibers of nanocellulose sheathed with a
conductive polymer coating, scientists have created sheets of paper that
can store significant amounts of electric charge. Dubbed "power paper," the material is able to be recharged
many hundreds of time, and in mere seconds. It is also
no toxic chemicals or heavy metals to create, and may offer a renewable
and prolific way to provide energy to all manner of devices.
Although methane is one of the most potent of the greenhouses gases, scientists still aren't entirely clear on all of its ground-based sources. That's why researchers from Sweden's Linköping and Stockholm universities have created a camera that's capable of imaging methane in real time. They say that it could find use in monitoring sources such as sludge deposits, combustion processes, farms and lakes.
In what seems like the most unlikely of unions, a team of scientists at the Linköping University Laboratory for Organic Electronics are working to combine flowers, bushes, and trees with electronics to produce a breed of botanical cyborgs. Led by Professor Magnus Berggren, the researchers have used semiconductive polymers to create the key components of analog and digital electronic circuits inside a rose plant.
Scientists have long believed that while an atom's outer electrons are highly mobile and often behave somewhat chaotically, the inner electrons close to the nucleus are stable. They move steadily around the nucleus and stay out of each other's way. But new research reveals that if the pressure is really extreme, like double that found at the center of the Earth, the innermost electrons of an atom change their behavior.
A new type of medical device could one day put the minds of chronic pain sufferers at ease by distributing the body's own natural pain relief signals at just the right time. Developed at Linköping University in Sweden, the tiny "ion pump" is made from organic electronics and could be implanted in patients, serving to cut off pain signals in the spinal chord before they make their way to the brain.
