Collaborate Disseminate
Fans of the Mission Impossible movies may recall the agents’ use of a slim, throat-mounted device that changes the user’s voice. Well, Chinese scientists have now developed something similar, that could one day allow the mute to speak &hellip… Continue reading Stick-on device could let the speechless "speak"
Incredibly thin, flexible, strong and electrically conductive, graphene has the potential to revolutionize electronics and materials. One of the main hurdles though is that it’s tricky to manufacture on large scales. Now researchers at the Un… Continue reading Bacteria recruited to produce graphene on the cheap
Carbon dioxide is kind of painted as the villain of the 21st century, and it’s not enough to just reduce our emissions now – we need to remove some of what’s already in the atmosphere. Now, researchers at Karlsruhe Institute of Technology (KI… Continue reading Carbon dioxide could be converted into graphene
The wonderful potential of graphene has been well covered on our pages, with its supreme strength, ultra-thin profile, and excellent electrical and thermal conductivity opening up all kinds of possibilities. One thing missing from all of this… Continue reading Making "green" graphene from gum trees could cut production costs by 200 times
It wasn’t long ago that graphene seemed to take the science and engineering communities by storm. You can make bits of it with a pencil and some sticky tape, yet it had all sorts of wonderful properties. The key, of course, is that it is a single layer of atoms. …read more
Even though the majority of the Earth is covered in water, a surprising number of people around the world don’t have easy access to clean drinking water. The oceans of course are full of salt, and it is difficult to filter that salt out. Researchers at the University of Manchester …read more
Of all the fictional cyborgs who turn against humanity to conquer the planet, this is as far from that possibility as you can get. These harmless mushrooms seem more interested in showing off their excellent fashion sense with a daring juxtaposition of hard grid lines with playful spirals. But the purpose of this bacteria-fungus-technology hybrid is to generate electricity. The mushrooms are there to play nurse to a layer of cyanobacteria, the green gel in the photo, while the straight black lines harvest electricity.
Cyanobacteria do not live very long under these kinds of conditions, so long-term use is out …read more
Some of the creepy-crawlers under our feet, flitting through the air, and waiting on silk webs, incorporate metals into their rigid body parts and make themselves harder. Like Mega Man, they absorb the metals to improve themselves. In addition to making their bodies harder, silk-producing creatures like worms and spiders can spin webs with augmented properties. These silks can be conductive, insulating, or stronger depending on the doping elements.
At Italy’s University of Trento, they are pushing the limits and dosing spiders with single-wall carbon nanotubes and graphene. The carbon is suspended in water and sprayed into the spider’s habitat. …read more
It is sort of an electronics rule 34 that if something occurs, someone needs to sense it. [Bblorgggg], for reasons that aren’t immediately obvious, needs to sense ants moving over trees. No kidding. How are you going to do that? His answer was to use graphene.
Actually, his super sensitive sensors mix graphene in Silly Putty, an unlikely combination that he tried after reading (on Hackaday, no less) about similar experiments at Trinity College resulting in Gputty. The Gputty was highly sensitive to pressure, and so it appears is his DIY version called Goophene. At Trinity they claimed to be …read more
