Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb-like pattern. Graphene is considered to be the world's thinnest, strongest and most conductive material - to both electricity and heat. All this properties are exciting researchers and businesses around the world - as graphene has the potential the revolutionize entire industries - in the fields of electricity, conductivity, energy generation, batteries, sensors and more.
Graphene is the world's strongest material, and so can be used to enhance the strength of other materials. Dozens of researches have demonstrated that adding even a trade amount of graphene to plastics, metals or other materials can make these materials much stronger - or lighter (as you can use less amount of material to achieve the same strength).
Such graphene-enhanced composite materials can find uses in aerospace, building materials, mobile devices, and many other applications.
Graphene is the world's most conductive material to heat. As graphene is also strong and light, it means that it is a great material to make heat-spreading solutions, such as heat sinks or films used to dissipate heat. This could be useful in both microelectronics (for example to make LED lighting more efficient and longer lasting) and also in larger applications - for example thermal foils for mobile devices. Huawei's latest smartphones, for example, adopt graphene-based thermal films.
Because graphene is the world's thinnest material, it is also the material with the highest surface-area to volume ratio. This makes graphene a very promising material to be used in batteries and supercapacitors. Graphene may enable batteries and supercapacitors (and even fuel-cells) that can store more energy - and charge faster, too.
Coatings ,sensors, electronics and more
Graphene has a lot of other promising applications: anti-corrosion coatings and paints, efficient and precise sensors, faster and efficient electronics, flexible displays, efficient solar panels, faster DNA sequencing, drug delivery, and more.
Graphene is such a great and basic building block that it seems that any industry can benefit from this new material. Time will tell where graphene will indeed make an impact - or whether other new materials will be more suitable.
The latest Graphene Application news:
Highways contractor Amey and its client Kent County Council will be testing Gipave, an Italian graphene-based asphalt supermodifier said to extend pavement life.
The trial is taking place as part of the Association of Directors of Environment, Economy, Planning & Transport (ADEPT) Smart Places Live Labs programme funded by the Department for Transport of the UK.
Collaborative research between Flinders University's Institute for NanoScale Science and Technology and the Centre for Health Technologies at the University of Technology Sydney has used VFD technology to enable the preparation of a new generation of aggregation-induced emission dye (AIE) luminogens using graphene oxide (GO).
Traditional fluorescent dyes to examine bacteria viability are toxic and suffer poor photostability, so researchers are constantly looking for alternatives. Using the VFD to produce GO/AIE probes with the property of high fluorescence is said to be very promising—with the new GO/AIE nanoprobe having 1400% brighter fluorescent performance than AIE luminogen alone.
U.S-based motorcycle maker Indian Motorcycle has launched a new graphene-based technology Called ClimaCommand Classic Seat, which aims to deliver both heating and cooling to riders and passengers. The thermo-electric technology reportedly raises the bar on cooling, providing a much more effective solution than HVAC convection systems.
A critical performance benefit of the ClimaCommand technology is that it actually produces a surface that’s cold to the touch, rather than merely pushing cool air through perforations in the surface in the manner that HVAC system offerings operate.
Brown researchers combine a ceramic material with graphene to create the toughest solid electrolyte built to date
A team of Brown University researchers has found a way to double the toughness of a ceramic material used to make solid-state lithium ion batteries. The new strategy could be useful in bringing solid-state batteries to the mass market.
“There’s huge interest in replacing the liquid electrolytes in current batteries with ceramic materials because they’re safer and can provide higher energy density,” said Christos Athanasiou, a postdoctoral researcher in Brown’s School of Engineering and lead author of the research. “So far, research on solid electrolytes has focused on optimizing their chemical properties. With this work, we’re focusing on the mechanical properties, in the hope of making them safer and more practical for widespread use.”
Sweden-based 2D fab has recently closed a new share issue of approximately €700,000. The capital will primarily be used for developing the organization and for commercializing the Company's graphene products.
The share issue was directed to a limited number of investors, having received the offer either via the company's executive management or via G&W Fondkommission. Through this transaction 2D fab received eleven new owners, among them Malmö based Polynom Investment.
