Researchers reach graphene-based junctions that are both electrically and mechanically stable

A research team jointly led by University of Warwick and EMPA has tackled a challenging issue of stability and reproducibility in working with graphene, that meant that graphene-based junctions were either mechanically stable or electrically stable but not both at the same time.

Graphene and graphene like molecules are attractive choices for electronic components in molecular devices, but have proven very challenging to use in large scale production of molecular devices that will work and be robust at room temperatures. The joint research team from the University of Warwick, EMPA and Lancaster and Bern Universities has reached both electrical and mechanical stability in graphene-based junctions.

XG Sciences partners with Niagara Bottling to advance graphene PET innovations in food & beverage packaging

XG Sciences (XGS) recently announced that it has entered into an Intellectual Property License, Joint Development and Commercialization Agreement with Niagara Bottling, a market leader in beverage packaging innovation and one of the largest beverage companies in the U.S.

The agreement provides XG Sciences with an exclusive license to Niagara’s patents and proprietary know-how related to the use of graphene nanoplatelets in PET in certain bottle applications. Under the agreement, Niagara will assist XGS with field engineering support to install products into the manufacturing lines for new customers – greatly reducing the manufacturer’s time to market.

Graphene Composites exceeds crowdfunding target for graphene bulletproof shields

Graphene Composites, a UK-based company developing graphene-enhanced bulletproof shields, has exceeded its crowdfunding target. GC attempted to raise £300,000 on Crowdcube, but ended up raising £510,680 (around 676,625 USD).

Graphenest launches two graphene products with pre-order campaign

Graphenest has launched two products, based on a proprietary graphene production method, now available to pre-order with a campaign price for a limited time.

The first product is HexaShield, a graphene-based paintable coating for RF electromagnetic interference (EMI) and radiation shielding. It reportedly provides drastic weight reduction, and reduced manufacturing cost as compared to metals, while achieving the required protection for the Gigahertz frequency range.

Graphene Flagship partners present a graphene-enhanced leading edge for the Airbus A350

Graphene Flagship partners Aernnova, Grupo Antolin-Ingenieria and Airbus have produced a leading edge for the Airbus A350 horizontal tail plane using graphene-enhanced composites. As the first part of the tail plane to contact air, the leading edge is subjected to extreme temperatures caused by compressive heating of the air ahead of the wing. Thus, it must possess excellent mechanical and thermal properties.

“Aernnova supplied the resin to Grupo Antolin-Ingenieria who added graphene directly to the resin and applied milling forces,” said Ana Reguero of Aernnova. “This creates small graphene particles – an important step to get good graphene infiltration within the resin, avoiding unwanted impurities, such as solvents, which can alter the viscosity of the resin. It is important to maintain the correct viscosity of the resin to ensure the optimal outcome during the resin transfer molding of the leading edge.”
