Graphenano announces collaboration with Tecnivial on graphene signs

Graphenano Composites has signed an agreement with Tecnivial to improve the properties of the composites used in its traffic safety signs for airports, railways and roads by the incorporation of graphene. The signs are reportedly based on a compound formed by Advantex fiber fabrics mixed with thermosetting plastic resins and doped with graphene nanoparticles.

First Graphene reports on the progress of its graphene-enhanced cement project

First Graphene has provided an update on its work with the University of Adelaide (UoA) on graphene for enhancement of industrial building products. The UoA is testing FGR graphene, with the aim of making smart cement with conductive graphene flakes with aims to address the concerns of cracking and corrosion and provide conductivity for better monitoring of the health of concrete structures.

According to FGR, the first test results indicate the addition of 0.03% standard graphene is the optimal quantity of graphene from the test conducted to date, showing a 22 - 23 % increase in compressive and tensile strength, respectively. The addition of more standard graphene does not reportedly increase or decrease the strength of the concrete material when compared to the control in this test work.

MITO receives a $224,988 grant to develop an additive that enhances the toughness of composite materials

MITO Material SolutionsMITO Materials Solutions logo image has been awarded a National Science Foundation (NSF) Small Business Innovation Research (SBIR) grant of $224,988 to develop a graphene oxide-based nano-additive that doubles the interlaminar toughness of composite materials utilized in aerospace, recreation, and automotive industries.

The main focus of this project is the development of new hybrid nanofillers based on Graphene Oxide (GO) and Polyhedral Oligomeric Silsesquioxane (POSS). These nanofillers can be added to epoxy/vinyl ester/polyester matrices through a "Master Batch" process to enhance the interlaminar fracture toughness of commercial composites.

Graphene-fed spiders spin ultra-silk

Italian and British researchers have created a unique kind of material, produced by spiders that were "fed" with miscrosopic flaked of graphene and CNTs.

The scientists fed "special" water to three species of spiders. Dispersed within it were microscopic flakes of graphene, or carbon nanotubes. When silk was subsequently gathered from the spiders, it was found that the graphene/nanotubes had been passed into the fibers. As a result, its tensile strength and toughness were much higher than that of regular spider silk.

Applied Graphene Materials enters agreement to develop and commercialize a new graphene ink technology

Applied Graphene Materials has outlined details of a new graphene-enhanced ink technology and signed a development deal with the University of Sheffield Advanced Manufacturing Research Center. A patent for this new development, called Structural Ink, has been registered and once fully commercialized, the product will be targeted at the advanced composites industry.

The technology will aim to enable users to increase mechanical toughness, through the addition of graphene. This is ultimately designed to improve performance, enable further weight reduction and reduce total manufacturing costs.

Talga reports impressive concrete strength test results using its graphene

Australia-based technology minerals company, Talga Resources, recently announced impressive initial concrete prototype strength results from trials undertaken at the commercial concrete/cement laboratory of Betotech Baustofflabor in Germany.

Graphene and graphite enhanced cement and concrete are key priority product targets for Talga. Concrete test prototypes were formulated with Talga graphene and graphite additives combined with a European industry cement and aggregate mixture. Results from the trial showed significant increases, about 26% in flexural strength and 14% in compressive strength, using Talga materials over reference concrete at 28 days cure time.

Graphene assists in creating lighter car parts

Researchers at The University of Alabama used graphene to fabricate a lighter car hood, as part of an attempt to reduce the weight of a Chevrolet Camaro. The new hood is made of a mixture of graphene and carbon fiber, as opposed to the original hood which is made of aluminum.

The hood is half the weight of the original hood, a crucial adjustment as a larger team of students work to turn the Camaro into a plug-in hybrid as part of a national contest called EcoCAR 3.

Sir Richard Branson excited about graphene's future in aerospace

In a recent speech, Virgin Atlantic president Sir Richard Branson raised the prospect of planes being made entirely from graphene within 10 years. Counting on graphene's mechanical strength and light nature, he hopes the aerospace industry could welcome light, durable planes that will cut fuel expenses, among other advantages.

He was quoted saying "hopefully graphene can be the planes of the future. 10 years down the line. They would be massively lighter than the current planes, which again would make a difference on fuel burn." Branson likened the push for graphene planes to urging Airbus and Boeing to make planes from carbon fibre, a battle he won. Boeing's latest 787 Dreamliner planes are made from 50% carbon fibre and other composite materials, as opposed to the traditional 100% aluminium. They use 30% less fuel than their standard alternatives.

Rice team's CNT-reinforced graphene foam is conductive and strong

Researchers at Rice University have constructed a graphene foam, reinforced by carbon nanotubes, that can support more than 3,000 times its own weight and bounce back to its original height. In addition, its shape and size are easily controlled - which the team demonstrated by creating a screw-shaped piece of the material.

The 3D structures were created from a powdered nickel catalyst, surfactant-wrapped multiwall nanotubes and sugar as a carbon source. The materials were mixed and the water evaporated; the resulting pellets were pressed into a steel die and then heated in a chemical vapor deposition furnace, which turned the available carbon into graphene. After further processing to remove remnants of nickel, the result was an all-carbon foam in the shape of the die, in this case a screw. The team said the method will be easy to scale up.
