Graphene coating may solve the glass corrosion problem

Oct 21, 2016

Researchers at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS), have demonstrated a graphene coating that protects glass from corrosion. Their research has been said to hold potential for solving problems related to glass corrosion in several industries.

Graphene coating against glass corrosion image

The IBS scientists grew graphene on copper and transferred either one or two atom-thick layers of graphene onto both sides of rectangular pieces of glass. The effectiveness of the graphene coating was evaluated by water immersion testing and observing the differences between uncoated and coated glass. After 120 days of immersion in water at 60 C, uncoated glass samples had significantly increased in surface roughness and defects, and reduced in fracture strength. In contrast, both the single and double layer graphene-coated glasses had essentially no change in both fracture strength and surface roughness.

Saint Jean Carbon develops hybrid graphene sheets with superconductivity

Oct 20, 2016

Saint Jean Carbon, a carbon science company engaged in the exploration of natural graphite properties and related carbon products, has announced the development of hybrid graphene sheets with superconductivity. The work is the ongoing development of a number of different areas of research between Saint Jean and University of Western Ontario.

The hybrid graphene nanosheets were created by depositing yttrium barium copper oxide (YBCO) superconductor particles and were developed by using the matrix-assisted pulsed laser evaporation (MAPLE) method. With increasing irradiation time, the amount of YBCO nanoparticles deposited on graphene is increased. In addition, the microstructures and elemental composition of YBCO nanoparticle deposited on graphene sheet by the MAPLE process were studied in terms of particle size and shape as a function of the deposition time/irradiation time. It is noted that the shape and size of the YBCO nanoparticles are more uniform with increasing the deposition time. When it increases to 2 hours, the average diameter of the spherical YBCO nanoparticles deposited on graphene sheets is around 50 ± 10 nm. This study demonstrates that MAPLE is a suitable process for depositing inorganic superconductor nanoparticles on graphene sheets without additional chemical agents.

Russian team makes graphene with high stability under ozonation, with great potential for nanoelectronics

Oct 20, 2016

Scientists from Russia's National Research Nuclear University MEPhI have succeeded in producing graphene with a very high stability to ozonation using high-temperature sublimation of silicon carbide (SiC). The resulting graphene maintains contact with ozone for more than 10 minutes (while ordinary graphene loses its properties after only three or four minutes under such conditions). These results may hold great potential for the development of nanoelectronics.

To further examine the effects, scientists from Greece, France and Sweden were brought onto the team. Using computer modeling, the experts were able to figure out why SiC-graphene was more stable under the impact of aggressive oxygen free radicals. The new graphene's abnormal stability appeared to be associated with the low roughness of epitaxial graphene on SiC-substrate (epitaxy is a natural buildup of one crystalline material upon the surface of another).

Graphene-based transparent electrodes to promote stroke and epilepsy research

Oct 20, 2016

Scientists at the University of Wisconsin–Madison have looked into graphene-based microelectrocorticography (uECoG) arrays, used in neuroscience researcher, searching for possibilities to expand the use of the arrays in areas such as the research of stroke or epilepsy. Researchers at the University of Wisconsin-Milwaukee, Medtronic PLC Neuromodulation, the University of Washington, and Mahidol University in Bangkok, Thailand were also involved in this study.

Graphene transparent electrodes for neuroscience image

The researchers see graphene as one of the most promising candidates for transparent neural electrodes, because the material has a UV to IR transparency of more than 90%, in addition to its high electrical and thermal conductivity, flexibility, and biocompatibility. That allows for simultaneous high-resolution imaging and optogenetic control, according to the team.

Grafoid enters agreement to sell its share in Braille Batteries

Oct 19, 2016

Grafoid logoMincom Capital has announced it has entered into a non-binding letter of intent with Grafoid to acquire Grafoid's 75% interest in Braille Holdings which owns Braille Battery. The proposed purchase price is $2 million USD, of which $1 million USD will be paid in cash and $1 million USD will be paid in shares issued to Grafoid from the treasury of Mincom. To fund this acquisition, Mincom plans to raise around $3 million USD.

Grafoid stated that "We see future market opportunities for high performing next generation batteries in the bus and truck manufacturing sectors and we see trends emerging in marine, aviation and medical equipment and other industrial sectors that might benefit from graphene-based energy solutions".

Applied Graphene Materials supplies graphene for next-gen fishing rods

Oct 18, 2016

Applied Graphene Materials has announced that it has supplied its graphene material for use in the production of a range of fishing rods, made by UK's Century Composites. Century has unveiled a new range of fishing rods containing the AGM's GNPs, sold under the brand Graphex.
