"Spicy world of NanoScience" since 2007
Researchers from the University of Florida and Hunan Univeristy developed DNA-directed silver nanoparticles (Ag NPs) grown on graphene oxide (GO). These so called Ag@dsDNA@GO composites act as antibacterial agents, decreasing X. perforans (a model plant pathogenic bacterium) cell viability in culture and on plants.
In a greenhouse experiment they applied this material on tomato transplants and they reported significant reduction of disease caused by bacterial spot compared to the…

A chinese company (called Powerbooster) is developing graphene-based flexible touch panels for mobile devices. The company claims they are already producing 2 million units per month and are in talks with mid-size Chinese phone makers to incorporate these into mobile phones. They hope to have products on the market by the end of the year, and they aim to invest $150 million in the next 3 years to bring this to market:…

Researchers from MIT are developing graphene and molybdenum-disulfide based solar cells that may become the world's most efficient solar cells. A single layer system (made from 1 graphene sheet and one MD sheet) achieves 1%-2% conversion while being only 1 nm thick. A silicon solar cells achieves 15%-20% efficiency but is hundreds of thousands times thicker. You can use several layers on top of each other to boost efficiency:…

Bluestone Global Tech (BGT) was founded in 2011 in New York with an aim to produce high quality graphene. We posted an interview with the company's CEO, and he says they expect graphene-based touch panels by Q3 2013 from one of their customers. He believes that the penetration rate for graphene over ITO will be quite a remarkable replacement rate of 5% in 2014.…

Researchers from EPFL designed a new flash memory cell prototype that is made from graphene and Molybdenite (MoS2). They say that the new design is efficient, flexible, small and fast. The idea is that the unique electronic properties of MoS2 (it has an "idea energy band") are combined with graphene's excellent conductivity:…

Researchers from the University of California, Berkeley, have developed a new graphene-based earphone-sized speaker - that can actually outperform the best earphones. They say that even with almost no specialized acoustic design, it performs comparably to a high quality commercial headsets (a Sennheiser MX-400 earphone, in fact). The graphene speaker is also highly efficient:…
Cabot Corporation launched the LITX G700, the company's first graphene-based additive for high energy density lithium-ion batteries. They say that this additive will allow Li-Ion battery makers to achieve superior cell performance.

Back in May 2011, a graphene research program (called GRAPHENE-CA) was shortlisted for one of two €1 billion EU research initiatives. Today we're happy to report that this project was indeed chosen by the European Commission. This is set to be a huge boost to graphene research and will hopefully accelerate commercialization of graphene based products. The EU will officially announce their decision next week (January 28):…

Researchers from Rice University and Lomonosov Moscow State University discovered that Graphene Oxide can quickly remove radioactive material from contaminated water. They found out that graphene oxide bind quickly to natural and human-made radionuclides and condense them into solids.
This discovery is obviously useful in contaminated site cleanups (such as the Fukushima nuclear plants), but is also useful in hydraulic fracturing (“fracking”) for oil and gas recovery and rare…
