Graphene-Info is the web's leading resource on graphene material technology
Graphene is the world's strongest, thinnest and most conductive material, made from carbon. Graphene's remarkable properties enable exciting new applications. Our site brings you daily news and resources, all graphene focused.
Recent Graphene news:
Researchers from Australia and Ireland developed a flexible yarn made from graphene oxide. This strong, lightweight, highly conductive and high capacitance fiber may be a great material for wearable textiles.
The researchers report that the new yarns and fibers exhibit the best electrochemical capacitance ever - of as high as 410 F/g. To create the fiber, the researchers used a novel wet-spinning technique that can produce both GO and r-GO yarns of unlimited lengths. Those yarns are strong (with a Young’s modulus that is greater than 29 GPa), have a high electrical conductivity of around 2500 S/m and a very large surface area – about 2600 m2/g for graphene oxide and 2210 m2/g for the reduced material.
Grafen Chemical Industries announced that Dubai based investment company Al-Hamlah Investment Group plans to invest $1.8 million in the company - to help fund its R&D, production and supply business.
Grafen is currently focused on its CrowdLit business model, a customer specific supply chain nanomaterials development process. Grafen will use the funds mainly towards this model , but will also support it's current graphene R&D.
Young researchers from the EU to develop an ultra-compact graphene-based mid-infrared broadband light source
The EU launched a new project called Graphenics that aims to develop an ultra-compact graphene-based mid-infrared broadband light source. The project include researchers from Belgium, Austria, Poland and Canada. The hope to achieve a highly compact and portable device, that will pave the way to mid-infrared broadband light sources in applications such as medical diagnostics and optical safety testing of water.
The researchers say that the main issue stopping the widespread adoption of broadband mid-infrared light source is the source compactness and portability. The researchers hope to develop a chip in which both the chip and the pump laser exciting the chip are made extremely compact.
Researchers from the University of Cincinnati say that adding even a small fraction of graphene flakes to a polymer-blend bulk-heterojunction (BHJ) solar cell can improve the performance of those solar cells. In fact, the efficiency increased threefold compared to the same cell without graphene.
The researchers explain that graphene's very high charge conductivity helps to maximize the energy absorbed by the plastic solar cell. The performance of these cells is still "well below" the highest efficiency achieved in organic photovoltaic (OPV) devices.
I'm happy to announce that today I launched a new graphene photos gallery here on Graphene-Info. If you're looking for photos of graphene, this may be useful.
I have listed those photos in five sections: graphene prototypes, graphene photos, graphene products, graphene materials and computer generated renders of graphene or related materials. Enjoy!
Researchers from Harvard University, FEI Corporation and the Lawrence Berkeley National Lab, in collaboration with Graphenea, invented a new atomic “chisel” made from a single silicon atom that can be used to make pores or nanostructures in graphene. This can be used to create clear edges for nanoribbons, open nanopres for DNA sequencing and fabricate a host of nanostructures for use in future molecular electronics devices and make nanopores for DNA sequencing applications.
The atomic "chisel" is made from a silicon atom and is controlled by a high-energy beam in a transmission electron microscope. This produces a catalytic wedge. The kinetic energy from the electron beam helps to selectively chip off carbon atoms from the graphene lattice one by one so we obtain nice clean holes or edges in the carbon material.
UK-based Perpetuus Carbon Technologies announced that it entered the graphene supply market. The company will soon start production of customer-tailored surface modified graphene materials (excellent quality stacked graphene flakes) in its new 100 annual ton facility. The company can provide 50Kb batches within 48 hours and ton-sized orders within 28 days. The price of their graphene materials is £50 ($83) per kilogram.
The company also holds an R&D arm (called Perpetuus Research and Development). The development activities focus on graphene based ink, and also include transparent condcutive films (for ITO replacement), stress strain actuators and printable coatable electrodes for use in lithium Ion batteries.
