The Graphene World Summit will address the latest advancements in the global application, standardisation and production of graphene. âLearn the latest about topics like:
Researchers at MIT and Lawrence Berkeley National Laboratory have developed a novel kind of tunable catalyst that could potentially replace costly rare metals that are currently used in fuel cells. The catalyst is made of graphite, with additional compounds attached to the edges of the 2D sheets of graphene that the material is composed of. The catalyst’s characteristics can be tuned to promote specific chemical reactions by altering the composition and the quantities of the additional compounds.
The scientists aimed at merging the attributes of two different electrocatalysts - Molecular electrocatalysts, that can be tuned through chemical treatment so their selectivity and reactivity can be customized, and heterogeneous electrocatalysts that can't be tuned precisely but are known for their durability and ease of processing into a device. The team worked towards chemically modifying graphite’s structure to provide the desired tunability.
Graphene Nanochem has inked a commercial order for its graphene-enhanced PlatQuartz lubricant additive from Scomi Oiltools. The PlatQuartz products are nanofluids designed to enable high temperature and pressure performance for water-based drilling muds, improving torque and drag when drilling.
The order is worth $390,000 and is to be deployed to an oil and gas company in India for a 3-well drilling programme.
A research partnership between the University of Central Lancashire’s College of Science and Technology and Civic Drone Center, and the University of Manchester’s National Graphene Institute yielded a graphene-enhanced UAV (unmanned aerial vehicle).
A test flight of the UAV was recently carried out, aiming to trial the graphene within the UAV to test its robustness, aerodynamic properties and how it can be integrated into the manufacturing process. The researchers work to explore how graphene can be integrated within the aerospace industry, and collaborating with the National Graphene Institute provided the partners with an opportunity to conduct research with a viable real-world application.
Skeleton Technologies is to supply graphene-based supercapacitors to Milrem's multipurpose UGV (unmanned ground vehicle) to be showcased at DSEI 2015. Milrem (Military Repair, Engineering and Maintenance) is an Estonian company whose mission is to be a partner in the defence and security sector, offering flexible product development solutions and full life cycle support for heavy vehicles. Milrem is also developing a mobile command post and an unmanned tracked vehicle for military purposes.
Skeleton Technologies' high power cells will be used to deliver energy efficiency and product reliability to the UGV, which can be used for a wide range of defense requirements including reconnaissance and observer missions, targeting weapon systems and providing support solutions such as medical supplies. The universal platform allows operators to optimize their vehicle fleet and reduce life cycle management costs with simplified maintenance and spare supplies.

Haydale has signed a letter of intent with Huntsman Advanced Materials, a leading global chemical solutions provider, to use the company’s graphene enabling technology together with Huntsman’s ARALDITE resins and heavy duty adhesives to create enhanced composites.
The agreed first step will be the development of a graphene enabled ‘master batch’ which will be used for development and validation. The companies hope that this work might open up the potential for a whole new range of advanced composite materials and products with enhanced performance and lower cost.
A newly published patent filing from LG reveals the specifications for a next-gen microwave oven that includes a graphene door to prevent the radiation inside from leaking out, ensuring more uniform heating. While the microwave itself sounds interesting, it seems that the manufacturing process, which follows a special layering approach, is the real innovation.
The process begins when a catalyst metal with microwave shielding properties such as copper is sandwiched between two layers of graphene synthesized by CVD. Next, a number of support materials are added to the structure in order to support the subsequent etching phases, which pattern the individual layers in a way that exposes both the graphene absorbent and the catalyst metal with its shielding properties for double effect.
In June 2015, researchers at the SAIT (Samsung's Advanced Institute of Technology) found a way to prolong the life of the standard lithium-ion batteries by using a new silicon cathode material "coded with high-crystalline graphene". Recent talk around the web suggests that this discovery may find its way to Samsung's Galaxy S7 and grant it a 5-day battery.
While the research is indeed impressive, and will hopefully be integrated in actual products in the future, it is important to say that we have no real indication that Samsung is close to commercializing their findings. Since the S7 is not scheduled for release until March 2016, there's still time for surprises...
As part of project GLADIATOR, The Fraunhofer Institute FEP will show an innovative organic light emitting diodes (OLEDs) with a graphene-based electrode at Plastic Electronics 2015. The fabricated OLED on transparent graphene electrodes has been realized on a small area, and the target of the next one and a half years of the project is to successfully achieve large area OLEDs.
With graphene as an electrode, the researchers at the Fraunhofer FEP hope for flexible devices with higher stability. The electrode contains CVD-produced monolayer graphene of high quality, supplied by Graphenea, in order to compete with the reference material ITO (which graphene, in this case, replaces), the transparency and conductivity of graphene must be very high. Therefore, not only the process of electrode manufacturing is being optimized, but also different ways of doping graphene to improve its properties are being examined.
