Graphene is the world's strongest, thinnest and most conductive material, made from carbon. Graphene's remarkable properties enable exciting new applications in electronics, solar panels, batteries, medicine, aerospace, 3D printing and more!
Recent Graphene news:
Researchers at VIT University, India demonstrated the application of conjugated polymer/Graphene oxide nanocomposite for thermistor applications. The study resulted in a thermistor that boasted excellent performance, suitable for electronics and sensors. A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.
Interestingly, the study showed that lower amounts of graphene oxide (0.5, 1%) loading exhibited positive temperature coefficient, and higher loading (1.5, 2%) yielded negative temperature coefficient.
Alabama Graphite announced the closing of a $2.875 million private placement. The company issues 14,375,000 units at $0.2 each, and each unit comprises of a common share and one-half of a common share purchase warrant ($0.35 exercise price).
The proceeds of this sale will be used for drilling, testing and assessments at its graphite mines and prospects, and in addition will be used for 'graphene initiatives'.
An international team of researchers from the Center for Integrated Nanostructure Physics at the Institute for Basic Science (IBS) and Department of Energy Science at Sungkyunkwan University in South Korea, has devised a new technique for creating a graphene-based MSC (solid-state micro-supercapacitor) that is said to deliver improved electrochemical performance, with a design based on the intricate design of leaves.
The team designed their MSC film structure in compliance with vein-textured leaves in order to take advantage of the natural transport pathways which enable efficient ion diffusion parallel to the graphene planes found within them. To create this efficient shape, the team layered a graphene-hybrid film with copper hydroxide nanowires. After many alternating layers they achieved the desired thickness, and added an acid solution to dissolve the nanowires so that a thin film with nano-impressions was all that remained.
Haydale has announced further progress in North America in the form of a service agreement with InVentures Groups, as well as the opening of a new office. The location of the new office and R&D facility, which is expected to be opened this month, is still under evaluation and likely to be in New York State.
The service agreement with InVentures is a rolling one year service agreement that dictates that InVentures will provide Haydale with financial, strategic and management planning advice to develop a center of excellence and establish Haydale as a leading provider of functionalized graphene and other nanomaterials to the North American market. In return, Haydale will provide an initial HT60 reactor to the USA to enable the functionalization of graphene and other nano materials on site. This reactor will provide sampling and low volume functionalized nano materials to the US market.
This book focuses on practical graphene applications, and discusses the mechanisms of electric and thermal transport in the gated graphene, interface phenomena, quantum dots, non-equilibrium states, scattering and dissipation, as well as coherent transport in graphene junctions. Detailed analyses and comparison between theory and experiments is complemented with a variety of practical examples.
Skeleton Technologies announced the launch of a new range of supercapacitors that are said to offer the highest level of energy density on the market. Through the use of patented graphene material, the new series boasts a capacitance of 4500 farads. The company claims that the closest competitor product has a capacitance of only 3400 farads.
Skeleton Technologies plans to use the SkelCap 4500 series to maximize opportunities in the heavy transportation and industrial markets where weight and space are at a premium. The new range has been designed for mass-market applications and the needs of systems engineers. The format has been developed to meet the industry standard of a 60 mm diameter cylindrical cell. Skeleton Technologies had previously offered prismatic cells, which are more compact in modular arrangements but more expensive to produce. Skeleton Technologies also claims to have achieved one of the lowest ESR (equivalent series resistance) levels on the market at 0.095 mΩ. This factor is crucial as it greatly increases the efficiency of the cells by reducing the amount of energy that is lost as heat.
Graphene 3D Lab announced a distribution and manufacturing partnership with Polymaker. Under the terms of the agreement, Polymaker will distribute all Graphene 3D manufactured specialty and functional filaments and provide filament manufacturing services on an as required basis. Polymaker's manufacturing operation is located in China, and the company operates sales and distribution offices in China, New York, USA, Netherlands and Japan.
Graphene 3D's on-line filament store will carry unique Polymaker filaments, including PolyMax PLA, PolyFlexTM, and PolyWoodTM. Both companies plan to start offering each other's products on their respective on-line stores in July. The agreement also includes provisions for Graphene 3D and Polymaker to collaborate on the development of an expanded line of graphene filaments.
