We’ve already seen a pen
with silver-based ink, that lets its user draw electrical circuits on ordinary paper. Now, scientists from MIT have brought similar “hands on” technology to the humble pencil – they’ve compressed carbon nanotubes together to form a pencil lead substitute, that has been used to draw gas sensors onto regular paper imprinted with gold electrodes.
The UBC coren is what happens when creative minds get to run amok without the usual constraints imposed by reality. The new single speed bicycle combines a unique shape, belt drive and plenty of high-tech composite.
Scientists at the Massachusetts Institute of Technology (MIT) have succeeded in genetically altering Ralstonia eutropha
soil bacteria in such a way that they are able to convert carbon into isobutanol, an alcohol that can be blended with or even substituted for gasoline. It is hoped that once developed further, this technology could help reduce our reliance on fossil fuels, and
lessen the amount of carbon dioxide released into the atmosphere by smoke stacks.
Diamonds may be forever, but they aren’t what they were. True, they shine just as brightly and they’re as hard as ever, but scientists from the Carnegie Institution of Washington are giving them some competition. An international team led by Carnegie’s Lin Wang have discovered a new substance that is not quite crystalline and not quite non-crystalline, yet is hard enough to dent diamonds.
As manufacturers of smartphones and mobile devices strive to make their products increasingly portable, they repeatedly come up against the constraints of existing battery technology. However, Xiaodong Li, a professor at the University of South Carolina (USC) believes that we will soon be able to employ the clothes we wear to help overcome such challenges and to this end, Li has transformed T-shirt material into an energy storage medium which could one day be used to power portable devices.
Researchers at MIT have developed a new type of photovoltaic cell made with carbon nanotubes that captures solar energy in the near-infrared region of the spectrum, which conventional silicon solar cells don’t. The new design means solar cell efficiency could be greatly increased, boosting the chances to make solar power a more popular source of energy.
While there are plenty of ways to make carbon-based products from CO2
, these methods usually require a lot of energy because the CO2
molecules are so stable. If the energy comes from the burning of fossil fuels, then the net result will be more CO2
entering the atmosphere. Now a material scientist at Michigan Technological University has discovered a chemical reaction that not only soaks up CO2
, but also produces useful chemicals along with significant amounts of energy.
Imagine if every window of the 828-meter (2,717-foot) high Burj Khalifa
in Dubai was capable of generating electricity just like a PV panel. That's the promise of solar window technology like the RSi
and Sphelar cells
systems. Rather than using costly silicon for window-based collection of solar energy, Dr Mark Bissett proposes using a very thin layer of carbon nanotubes instead.
Hopefully, you’re not just throwing your used coffee grounds in the garbage ... are you? Not only are they compostable, but they can also be used in robot hands
, biofuel engines for cars
, warm sports clothing
, and as printer ink
. Now, it turns out that they have yet another use – a scientist from The City College of New York has discovered that they’re good at soaking up stinky sewer gas.
Carbon is the fourth-most-abundant element in the universe and comes in a wide variety of forms, called allotropes, including graphite, graphene
, and the hardest natural material known to man, diamonds. Now scientists have discovered a new form of carbon that is capable of withstanding extreme pressure stresses previously only observed in diamond. Unlike crystalline forms of carbon such as diamonds, whose hardness is highly dependent upon the direction in which the crystal is formed, the new form of carbon is amorphous meaning it could be equally strong in all directions.
