A team of UK researchers led by none other but Nobel Laureate Andre Geim – one of persons involved in graphene‘s discovery in 2004 – has shown that the wondrous two dimensional material graphene can used as a proton exchange membrane in fuel cells. The find took everybody by surprise since no one expected graphene could allow protons to pass through
Graphene could be used to make bullet-proof armour – up to ten times better than steel
It might not come as a surprise to hear that the world’s strongest material, graphene, was found to be a great impact absorber as well. After all, there always seems to be a study that adds to the growing list of graphene’s useful properties, be it lightness, flexibility or electrical conductivity. It’s been labeled as a wonder material because of
Graphene rubber bands: flexible, low-cost body sensors
Graphene, the wonder material shows its potential once again: now, using graphene and rubber bands, engineers have created a flexible sensor which has significant medical value and can be made cheaply. You really should know about graphene by now – we’ve written dozens of articles about it just in the past couple of years; but if you don’t, here’s your
Adding lithium makes graphite both transparent and conductive. A great game changer for the industry
Materials found in nature often speak of at least one comprise. Metals for instance are highly conductive, but not transparent. Plastics on the other hand can be made to be transparent, but they’re very poor electrical conductors. This annoying tradeoff has aggravated scientists for some time in their efforts to design better solar cells or touchscreen displays, which need the
Super-stretchable yarn made from graphene could change the industry
Chemical researchers at Penn State and Shinshu University report they’ve managed to isolate strong, stretchable graphene oxide fibers that are easily scrolled into yarns and have strengths approaching that of Kevlar. The fiber can be then further refined to act as a powerful and lightweight electrical conductor or can be directly used as a higher power cable. “We found this
Graphene: unlimited heat conductivity
It’s official – graphene is the wonder material of the millennium. A team of researchers at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the National Univ. of Singapore found that thermal conductivity of graphene diverges with the size of the samples. What’s the big deal? Well, the findings show that the thermal conductivity of graphene is not
Making graphene in a kitchen blender
A team led by Jonathan Coleman at Trinity College Dublin reports they’ve patented a technique that can easily produce large quantities of quality graphene. The method is so simple that the researchers have even been able to scale it down for use in a kitchen blender. The exact ‘recipe’ has yet to be disclosed, but nevertheless ZME readers are warranted they
Graphene speakers easily outperform traditional designs
I feel like a broken record – graphene is awesome at this, graphene is awesome at that… graphene is just awesome! A few months ago, we were telling you about the first graphene ear buds, which were really promising, but researchers still had a lot of work to make them commercially viable. Well, they’ve turned it up a notch, and designed the
Breakthrough: first time monolayer graphene made in bulk
We’ve written extensively about graphene here on ZME Science, awarding it much praise and promise. Truly, if you read a bit about what graphene can do [strength, conductivity, cost, etc], you’ll soon learn to love it. So, why aren’t we seeing graphene used everywhere, from computers to aerospace like so many science papers herald its potential applications? Well, serious graphene
Carbon nanotubes may help increase the efficiency of tomorrow’s solar cells
Every time a new manufacturing or development technology concerning solar cells was introduced, the futurists and tech pundits were quick to hail the coming of a new generation. The first were the monocrystal silicon cells doped with Phosphorus and Boron in a pn-junction; these are expensive to produce, yet comprise 80% of the total solar panel market. The second generation cells
Graphene Technology Could Give Us Predator Vision Contact Lenses
As a kid, looking at the Predator movies gave me goosebumps; it wasn’t the physical superiority of the Predator, but the technological advantages. I mean, he has all that shooting stuff, and teleportation and camouflage, and the vision… it was all too much! But the way science is crazily developing, we’re already starting to experiment with all that… and I’m
Graphene proves to be fantastic radio waves absorber
Ultra strong, a fantastic electrical conductor, and even suitable for better beer storage, graphene is dazzling the w0rld with its potential applications. Now, it seems there’s another use to add for the growing list of applications for the atom thick hexagon carbon structure. Scientists at Queen Mary University of London and the Cambridge Graphene Centre found that simply by layering a sheet
New graphene treatment may help the wonder material turn mainstream
Graphene, a 2-D array of carbon atoms arranged in a hexagon shape, is one of the most researched material today. We’ve written extensively before about its properties and uses, and indeed the future seems to belong to graphene where it’s sure to dominate the electronics industry. Before this can happen, however, graphene production and manipulation needs to become cheap and
Synthetic fuel production may become cheaper after using carbon nanofibers
In transportation, there aren’t that many alternative energy sources like in conventional industry, where you can supply a plant or even a home using solar, hydro or wind power. Before electric vehicles make a significant contribution (don’t hold your breath for too long), alternative means of fueling engines need to be found. This is why biofuels are growing so feverishly,
New technique that allows self-soldering of carbon nanotubes may help replace silicon transistors
Carbon nanotubes and graphene have been hailed time and again as the wonder materials that will change the face of technology in the future. Before silicon can be dethroned from its reigning position, however, a lot of manufacturing issues need to be addressed. A new technique developed by researchers at University of Illinois provides a simple and straight-forward way of
Scientists grow graphene on silver
The wonder material Graphene, the new wonder material that promises to open a new age in technology, just got a whole lot better. Researchers have reported improved interfacing of graphene with other 2-D materials – basically ‘growing’ graphene on silver. This resulted in an exceptionally pristine sample, presenting opportunities for ultrafast electronics and advanced optics/ “Silver is a widely used
World’s smallest radio shows graphene advantage
A team from Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard has managed to take advantage of graphene’s unique properties (it’s strength and electric conduction) to create a nano-mechanical system that can create FM signals – in other words, the world’s smallest radio. “This work is significant in that it demonstrates an
Graphene layered tanks may let beer stay fresh for far longer on the shelf
Scientists at Rice University have developed a method that combined graphene nanoribbons (GNRs) and a polymer to produce a lightweight storage medium for compressed gas. The resulting material may prove to be extremely useful in the auto industry where manufacturers are trying use compressed natural gas to its fullest potential or in the beverage industry where it could help beer
First computer made out of carbon nanotubes spells silicon demise in electronics
In an inspiring breakthrough, Stanford researchers have created the first ever working computer made entirely out of carbon nanotubes. The technology is still very infant, as the computer operates on just one bit of information, and can only count to 32. Theoretically, however, it can be scaled up to perform billions of operations given enough memory. With more refining, computers such
Graphene transistors made using DNA assembly
As electronics become ever thinner, smaller and faster, scientists always need to think ahead and develop solutions to accommodate the computing needs of the future. For one, it becomes clearer with each passing day that silicon – the most used material in electronics – can’t be used anymore for tomorrow’s tech since we’re nearing its maximum potential. Graphene, the wonder
