Recent Graphene news:
Talga Resources announced its plan to construct a graphene demonstration plant in central Germany. The plant is to produce between 100 t/y and 200 t/y of graphene, with feedstock sourced from Talga’s Swedish projects.
Talga says that the decision to proceed with a demonstration plant followed Talga’s success in moving its high-grade Swedish graphite ores from laboratory to bench top scale and replicating graphene process results in multiple countries with several parties. According to the company, the next stage of development will expand to a locked-cycle demonstration scale plant able to produce meaningful quantities of graphene and graphite for larger customer samples and material graphene sales in 2015.
Graphene NanoChem announced that it has launched the commercial deployment of its latest product offering, an oilfield recovery additive named PlatsurF through Scomi Oiltools, its joint venture partner. PlatsurF removes blockages caused by drilling residues or from production waste and reverses shortfalls in production caused by formation damage. The company states that smartfluids product "vastly improves" production rates in previously damaged wells with reduced waste generation.
Scomi will supply PlatsurF to the market, and has placed an order on behalf of an international oil company that is serviced by Scomi for an approximate 50 well drilling programme in Thailand using PlatsurF. Graphene NanoChem relays that the order will consist of an initial deployment of 40 drums of recovery additive for two wells in Thailand, as part of Scomi introducing the additive as a "product substitution".
Scientists at the University of Basel demonstrated for the first time that electrons in graphene can be moved along a predefined path. This movement occurs without loss and could provide a basis for electronics applications.
Electrons are known to move through graphene practically undisturbed – similar to rays of light. Attempts have been made to find a way to guide them, which the Basel team has now accomplished. The developed mechanism is based on a graphene property - combining an electrical field and a magnetic field makes the electrons move along a snake state. The line bends to the right, then to the left due to the sequence of positive and negative mass – a phenomenon unique to graphene that could be used as a novel switch that can be incorporated into a wide variety of devices and operated simply by altering the magnetic field or the electrical field.
Researchers from the University of Minnesota used an ultrathin black phosphorus film of only 20 layers of atoms to demonstrate high-speed data communication on nanoscale optical circuits. They report that the devices show improved efficiency compared to graphene-based ones.
The University of Minnesota team created intricate optical circuits in silicon and then laid thin flakes of black phosphorus over these structures using facilities at the University's Minnesota Nano Center. The team showed that the performance of the black phosphorus photodetectors even rivals that of comparable devices made of germanium, considered the gold standard in on-chip photodetection.
2-DTech is spearheading a project to improve anti-corrosive coatings through incorporation of graphene via a scalable and commercially-viable process. Copper has been in extensive use for this purpose, but its disadvantages are enough for 2-DTech to explore the production of high crystalline quality silicon-doped graphene as a replacement.
The introduction of silicon as a dopant aims to fortify the multi-layer graphene’s domain boundaries. This could result in an improvement in anti-corrosive silicon-graphene conductive films for application on to copper substrates via thermal chemical vapor deposition (TCVD). The combination would create an extremely thin coating while protecting against corrosion without disrupting the intra-domain
Haydale has recently ordered an additional significantly larger reactor, the HD200, to fulfill anticipated increased customer orders following successful sampling and supply from the smaller units.
The company also said that it has ordered a further three Rotovac HD60 units for delivery by the end of June and that the two new reactors delivered in December 2014 have become operational.
A website named Getinews reported The first mass produced graphene-enhanced phone. It is supposedly intended for a 30,000 piece production, and will contain graphene smartphone touch screen, battery and thermal films. The phone's core technology is provided by the Chongqing Institute of Technology and the Chinese Academy of green intelligent Ningbo Institute of Material Technology and Engineering.
According to reports, the graphene phone has a better touch performance and longer standby time and better thermal performance. While graphene-enhanced touchscreens are not unheard of, graphene batteries a little more of a stretch so it should perhaps be taken with a grain of salt.
