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:
Just a couple of weeks ago we released The Graphene Handbook, and now Lulu.com, our print on demand publisher is offering a 30% discount. You can now get the book for just $104.99! Just use coupon LULUVIP14234 when you check out. This great offer is valid through December 5th, so hurry up ;-)
If you prefer the digital edition (PDF download), it costs $97. We also offer site and enterprise license options.
Reading the Graphene Handbook, you'll learn all about:
The book also provides:
Haydale announced that it listed its HDPlas range of graphene (and CNT) materials for trade on the INSCX exchange, a global marketplace for nanomaterials and nanocommodities. The company appointed Fullerex as Haydale's agent.
INSCX is used by both researchers and commercial companies to purchase nanomaterials and products.
Researchers from Nokia's Research Center in Cambridge developed a new humidity sensor based on graphene oxide. The researchers say that the new sensor is ultra fast (the fastest humidity sensor ever reported, in fact), thanks to the graphene 2D structure and its superpermeability to water molecules. The sensor Nokia developed is thin (15 nm), transparent and flexible.
The sensor's response and recovery time (the time to go from 10% to 90% of the high humidity value and vice versa) is less than 100 ms. The response rate is a function of the thickness of the GO, the thicker the film, the slower the sensor. Nokia has filed several patent applications regarding this work.
Graphene Nanochem teams up with Scomi Oiltools to develop and market Graphene-enhanced drilling fluids
A couple of weeks ago Graphene Nanochem announced that it hopes to start selling htier graphene-enhanced PlatDrill drilling fluid soon, and now the company announced that they signed an agreement with Malaysia's Scomi Oiltools, a global supplier of drilling fluid services. Scomi will exclusively market a range of formulated PlatDrill series to the oilfield chemicals market.
Graphene NanoChem says that PlatDrill fluids deliver superior performance with lower environmental impact as well as better lubricity, load bearing capacity and higher viscosity properties. The first of the PlatDrill series were tested successfully tested and earmarked for deployment in Malaysia and Myanmar (pending the identification of suitable well sites by Scomi's customers).
Localized hyperthermia is a solid tumor treatment that uses heat (above 43 degrees Celsius) to boost the cytotoxic effects of chemotherapy or radiotherapy and also increases the permeability of tumor cells to drugs. Graphene Oxide is a possible agent because it absorbs light in the near-infrared range.
Researchers from Portugal and Spain studied in vitro laser dosage and cell irradiation exposure time. It was discovered that cell culture temperature (after irradiating cells that had taken up graphene oxide) increases preferentially with laser power rather than with exposure time. Moreover, when the laser power is increased, cell necrosis leads to an increase of cytokine release to the surrounding medium.
Four years since launching Graphene-Info, the site has grown dramatically together with the Graphene industry - it is being read now by tens of thousands of monthly readers and almost 3,000 people are subscribed to are mailing list. I often get requests from companies wanting to exposure their new products or services to the Graphene community and in general increase their presence in this industry.
While still offering advertisement banner campaigns, today I am launching a new option in Graphene-Info - company sponsorships. This will be an affordable (starting at $250 per year) way to promote your business and services in Graphene-Info. You can get more exposure, connect with Graphene-Info's excellent graphene branding and of course show your support!

Turkey's Grafen and Germany's LUM launched a new research towards water-based colloidal exfoliation process (called Liquid-Phase Direct Chemical Exfoliation)to produce graphene nanoplatelets in bulk. Grafen says that the new process is environmentally friendly, and will enable low-cost GNP production.
The companies report that initial phase research has already provided them with some strong results. The process converts large volume of raw graphite powder to graphene GNPs with nearly pristine crystal structure.
