Graphene-Info: the graphene experts

Directa Plus, producer and supplier of graphene-based products for use in consumer and industrial markets, has announced the receipt of two orders from an Italian work-wear customer with an aggregate value for Directa Plus of approximately €500,000 over the next two financial years.

Directa Plus’s Planar Thermal Circuit graphene technology will be incorporated in around 10,000 work-wear garments. The first order for approximately 2,000 garments with a value for Directa Plus of €150,000 is expected to be delivered in the 2018 financial year, with the second order for approximately 8,000 garments with a value of €350,000 expected to be delivered by mid 2019.

The Graphene-Info team attended this year's Graphene Week, organized by the Graphene Flagship in San Sebastian, Spain, 10-14 September 2018. The event attracted over 600 visitors from all over the world, and was extremely well organized.

While the talks and lectures were clearly scientifically-oriented, the commercial angle was also evident and many institutes and companies were there to show their recent product advancements. The Graphene Flagship's booth held a fascinating array of exhibits: graphene-enhanced retina and neural prosthesis (biomedical devices) by the ICN2 as a part of Braincom, Airbus' graphene composite for the leading edge of the tail of the Airbus A350, Nokia, Ericsson and AMO's graphene-based modulators and photodetectors for optical communications, a prosthetic robotic hand enhanced with graphene nerve sensors by the IIT, University of Cambridge's insole graphene-based pressure sensor and more.

Researchers at the University of California, Santa Cruz and Lawrence Livermore National Laboratory in California have developed a new fabrication technique to make capacitors enhanced with graphene. The resulting devices store a large amount of charge over a given surface area - an important metric for measuring the performance of a capacitor.

The new technique uses a 3D printer to construct a microscopic scaffold with porous graphene and then fills the structure with a kind of material called a pseudocapacitive gel, which is a kind of capacitor material that also behaves like a battery in some ways.

Versarien recently announced it will be collaborating with fire retardant coatings supplier Advanced Insulation to work on a graphene project.

The collaboration will focus on incorporating Versarien's Nanene few layer graphene nano-platelets into sub-sea insulation materials to improve tear resistance and reducing water absorption of these materials.

Researchers from Empa and the Adolphe Merkle Institute (AMI) in Fribourg have conducted studies on a 3D lung model to examine the behavior of graphene and graphene-like materials once they have been inhaled.

Thanks to the 3-D lung model, the researchers have succeeded in simulating the actual conditions at the blood-air barrier and the impact of graphene on the lung tissue as realistically as possible – without any tests on animals or humans. It is a cell model representing the lung alveoli. Conventional in vitro tests work with cell cultures from just one cell type – the newly established lung model, on the other hand, bears three different cell types, which simulate the conditions inside the lung, namely alveolar epithelial cells and two kinds of immune cells – macrophages and dendritic cells.

Following the news on Huawei's Mate 20 X phone that will use “graphene film cooling technology” for heat management purposes, we have now found out that the graphene producer for this Huawei phone will be China-based The Sixth Element Materials.

The Sixth Element Materials will be providing the graphene product, out of the Company's current 260 tons/year capacity. However, as Huawei graphene requirements is estimated to take up almost all of TSEM's available capacity, TSEM is working on increasing its capacity to 1000 tons/year, and intends to be on stream around the beginning 2020 (but the dates are not yet finalized).

Chinese telecommunications giant Huawei has launched Mate 20 series, which includes the Mate 20, Mate 20 Pro and Mate 20 X. In its Mate 20 X phone, the largest in the lineup with its 7.2-inch OLED display, Huawei uses “graphene film cooling technology” for heat management purposes.

Huawei states that its Mate 20 X features Huawei Supercool - "the world’s first liquid multi-dimensional cooling system with Vapor Chamber (VC) and Graphene Film used in smartphones". It reportedly conducts heat away fast, keeping the device cool even under heavy loads (as the device is touted as a gaming device).
