Recent Graphene news:
Graphene 3D Lab, the company focused on the development and commercialization of technologies which improve the capabilities of 3D printing, has released a video which shows the use of one of its conductive graphene filaments in a game controller. The filament can be used in 3D printing circuitry, capacitive touch sensors and electromagnetic and radio-frequency shielding:
Researchers from the National Cheng Kung University in Taiwan designed a new method for tweaking the properties of graphene by introducing defects into it. Precise control over the amount and nature of defects could bring about new applications of graphene in everything from drug delivery or electronics.
The scientists used a technique called electrochemical exfoliation to strip graphene layers from graphite flakes. By varying the voltage they discovered they could change the resulting graphene’s thickness, flake area, and number of defects – all of which alter its electrical and mechanical properties.
Manchester University has teamed up with Amsterdam-based paints and coatings company Akzo Nobel, to investigate graphene oxide-based paints that provide protection against rust and corrosion for large metal structures, such as oil rigs, tankers and bridges.
This collaboration between Akzo Nobel and Manchester University is part of a €1m partnership in corrosion research. Akzo Nobel says graphene oxide could provide an ultra-strong, non-corrosive coating for a wide range of industrial applications. Corrosion in its various forms is estimated to cost the global economy $3 trillion a year. Products to protect against corrosion represent an $18 billion world market.
Researchers at the University of Wollongong's Institute for Superconducting and Electronic Materials designed a graphene-based flexible, foldable, and lightweight energy storage device for use in next-gen wearable technology and also as a potential device for medical implants, like pacemakers.
The scientists devised a 3D structure: liquid graphene was mixed with a polymer and the combination was then solidified to form the carbon nanotubes. The resulting structure was made-up of three parts: graphene, a conductive polymer, and carbon nanotubes. These three parts take the form of single atom-thick networks, resembling carbon formed cylinders. The novel design is efficient because by separating out the layers of carbon, researchers are able to use both surfaces in the structure for charge accumulation. The scientists expect this design to lead to ultra-fast and efficient battery devices.
Researchers from Tsinghua University in Beijing demonstrated a graphene-based LED that not only can be tuned to emit different colors of light, but can do so across nearly the entire visible spectrum: from blue (450-nm wavelength) to red (750-nm wavelength)—basically all colors but the darkest blues and violets. Such a color tunable LED has never before been realized.
The scientists made the light-emitting material from the interface of two different forms of graphene. These forms are graphene oxide (GO) and reduced graphene oxide (rGO). Placed at the interface of the GO and rGO is a special type of partially reduced GO that has optical, physical, and chemical properties that lie somewhere in between those of GO and rGO. The most important "blended" property of the interfacial layer is that it has a series of discrete energy levels, which ultimately allows for the emission of light at many different energies, or colors.
The U.S-based graphene materials producer and applications developer Angstron Materials announced securing $5 million in capital to increase manufacturing capacity for its single and few-layer graphene materials and bring key technologies to market.
The company began seeking Pre-Series A funding in late 2014. According to the company, the investment partner (only named as a "key player in advanced materials and consumer electronics") brings extensive business and industry expertise to the table, along with a portfolio of major customers and collaborators.
Ionic Industries, a spin-off of minerals explorer Strategic Energy Resources, cooperated with Monash University to develop extremely thin graphene-based supercapacitors, able to store large amounts of energy. According to Ionic, the first battery prototype should be available within six months and more sophisticated prototypes in three to five years.
The supercapacitors are tiny - smaller than the diameter of human hair, actually. They were created following two years of rigorous experiments, using an ion beam to etch the supercapacitors on to wafers made of graphene. They are said to be able to be fully recharged in minutes and last longer than present battery technologies.
