Graphene oxide reinforced Nanocomposite for Naval/Marine applications

Researchers from India's VIT University developed new a basic nanocomposite material for naval/marine application devices. This material is anti-corrosive and is a high-performance functional device, which the researchers say suits the requirements for applications for marine and naval conditions (humidity, temperature, etc).

The material is a graphene-oxide reinforced/conjugated polymer nanocomposite. A PEDO-block-PEG polymer was used as a host medium, with graphene-oxide as a modifier and PVDF as crosslinker. The researchers say this is a novel composite that exhibits high performance in structure, thermal, morphology and electrical properties.

Graphene used to create tiny "drums" with possible memory and sensor applications

Researchers from TU Delft developed very small graphene membranes (or "drums") that can be used to detect extremely small changes in position and forces. These tiny drums have find applications as sensors, and may also be used as memory chips in a quantum computer.

The researchers refer to these membranes as tiny drums, and they actually demonstrated how you can use microwave-frequency light to play on those drums. The membranes acts as a mirror in an optomechanical cavity. The microwave photos were shot on the drums which acts like a mirror. The researchers were able to sense minute changes in the position of the graphene sheet - even a change of 17 femtometers, nearly 1/10000th of the diameter of an atom.

3D Graphtech Industries to investigate graphene-enabled 3D printing with CSIRO

3D Graphtech Industries, recently established in Australia by Kibaran Resources and the 3D Group, signed an initial agreement with Australia's CSIRO organization to investigate research opportunities in 3D printing using graphite and graphene inks.

CSIRO and 3DGI will jointly perform a white-paper study to identify technological problems in the 3D printing market that can be solved in an R&D program to provide a commercial solution. This is expected to take six weeks, and this initial agreement may lead to a longer-term relationship.

KAIST researchers develop new way to make defect-free graphene

Researchers at from Korea's KAIST institute developed a new method to fabricate defect-free graphene. Using this graphene, they developed a promising high-performance anode for Li-Ion batteries.

The method starts with a Pyrex tube and fill it with graphite powder. The open-ended tube is placed in another, larger tube and potassium is added to the gap between the tubes. The tubes are sealed and heated - which causes the potassium to move inside the micropores in the graphite powder - creating a potassium-graphite compound. This is placed in a pyridine solution, which expands the layer and separates them to form graphene nanosheets - which are then exfoliated to create a single graphene sheet.

Sixteen year-old suggests cleaning up the world by mixing graphene oxide with titanium dioxide

A sixteen year-old boy from Lancaster, England developed a composite material that he created from a pencil and sunscreen lotion, that can break down pollutants when exposed to UV light. He suggests using it as a "self-cleaning" coating.

The boy (Samuel Burrow) did some experiments and entered into Google's Science Fair 2014 competition and was eventually chosen as one of the 18 finalists. The grand prize in this competition is a $50,000 scholarship, a trip to the Galapagos islands and more.

New graphene characterization and standardization service company awarded £50,000 from The University of Manchester

In November 2013, the University of Manchester launched the second £50,000 Eli and Britt Harari Graphene Enterprise Award competition. A couple of days ago, they announced the winner of this year's award - Antonios Oikonomou for his Graphene Characterization and Standardization Services (GCSS) business enterprise.

GCSS, using the National Graphene Institute (at the University of Manchester) in-house expertise, will offer advanced graphene characterization, certification and standardization services. They aim to develop benchmark materials which can be developed into standards to be adopted by the industry.

MIT develops the world's most efficient transparent graphene electrode for polymer solar cells

Researchers from MIT developed a flexible transparent graphene-based electrode for graphene polymer solar cell (PSC). They report that this is the most efficient such electrode ever developed, with power conversion efficiencies of 6.1% (anode) and 7.1% (cathode).

To achieve the record efficiencies, the researchers thermally treated the MoO3 electron blocking layer and directly deposited a ZnO electron transporting layer on the graphene. The researchers say that the process is simple and reproducible.
