Adding graphene to alumina makes it 50% tougher

Graphenea researchers discovered that adding graphene to ceramic alumina can make it stronger - it is up to 50% less likely to break under strain. Graphenea's method is simple, fast and scalable, and it makes the alumina a hundred million times more conductive to electricity:

Will we see anti-bacterial graphene band-aids soon?

So, here's yet-another area where graphene may be useful: it turns out that graphene kills bacteria simply by slicing though them. This may enable simply graphene-based anti-bacteria "band-aids" soon:

MIT's new graphene based solar cells to achieve world's highest energy conversion efficiency

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:…

Will graphene be a good basis for 3D printing?

In past years we've seen graphene being used for many applications: transparent and flexible touch displays, sensors, batteries, solar panels, water purifications systems and more.



Today American Graphite Technologies (AGT) announced that it is going to research the possibility of using graphene-based materials as the workking materials for 3D printing. AGT will collaborate on this with Ukraine's Kharkiv Institute of Physics and Technology ("KIPT"):…

BGT promises first graphene-based touch panels by Q3 2013

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.…

Graphene and Molybdenite based flash memory is efficient, flexible, small and fast

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:…

New graphene-based earphone-sized speaker

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:…

Graphene research program to get €1 billion over ten years from the EU

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):…

Graphene Oxide used to soak radioactive waste

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…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
