Directa Plus signs contract to use graphene product to recover crude oil from European wells

Directa Plus recently announced that it has been awarded a supply and service contract from an unnamed international oil and gas company. The contract will involve treating and recovering crude oil from producing wells onshore across Europe.

Specifically, Directa Plus will be paid EUR150,000 to use its graphene-based Grafysorber technology, a product that is used to treat water contaminated by hydrocarbons, to treat several thousand cubic meters of sludges and by-products over the next six months.

Graphene research groups from Manchester University win £70,000 award

Two teams from the University of Manchester are the winners of a £70,000 prize for novel applications of graphene. Both teams are addressing key societal challenges on future energy and food security: seeking breakthroughs by using 2D materials to produce hydrogen to generate energy, and by designing polymer hydrogels to increase food production.

The Eli and Britt Harari Enterprise Award, in association with Nobel Laureate Sir Andre Geim, is awarded each year to help commercialize graphene concepts from Manchester University students, researchers and graduates. The prize is supported by former Manchester physics student, Dr. Eli Harari, founder of global flash-memory giant, SanDisk

Graphene may be the key to next-gen membranes that filter c02

A way to cut CO2 levels, produced from burning fossil fuels and released into the atmosphere, is through carbon capture, a chemical technique that removes CO2 from emissions ("postcombustion"). The captured CO2 can then be recycled or stored in gas or liquid form, a process known as sequestration.

Carbon capture can be done using high-performance membranes, which are polymer filters that can specifically pick out CO2 from a mix of gases, such as those emitted from a factory's flue. These membranes are environmentally friendly, they don't generate waste, they can intensify chemical processes, and can be used in a decentralized fashion. They are now considered as one of the most energy-efficient routes for reducing CO2 emissions. Now, scientists (led by Kumar Varoon Agrawal) at Ecole Polytechnique Federale de Lausanne (EPFL) have developed a new class of high-performance membranes that exceed post-combustion capture targets by a significant margin. The membranes are based on single-layer graphene with a selective layer thinner than 20 nm, and have highly tunable chemistry, meaning that they can pave the way for next-generation high-performance membranes for several critical separations.

Stanford team finds novel form of magnetism in twisted bi-layer graphene

Stanford physicists recently observed a novel form of magnetism, predicted but never seen before, that is generated when two graphene sheets are carefully stacked and rotated to a special angle. The researchers suggest the magnetism, called orbital ferromagnetism, could prove useful for certain applications, such as quantum computing.

We were not aiming for magnetism. We found what may be the most exciting thing in my career to date through partially targeted and partially accidental exploration, said study leader David Goldhaber-Gordon, a professor of physics at Stanford’s School of Humanities and Sciences. Our discovery shows that the most interesting things turn out to be surprises sometimes.

End-to-end processing chain of 2D materials successfully demonstrated as part of project "HEA2D"

Project "HEA2D", which started in 2016 and set out to investigate the production, qualities, and applications of 2D nanomaterials, recently demonstrated end-to-end processing chain of two-dimensional nanomaterials. The project is a collaboration between AIXTRON, AMO, Coatema, Fraunhofer and Kunststoff-Institut für die mittelständische Wirtschaft (K.I.M.W.).

It was stated that the "HEA2D" consortium successfully demonstrated an end-to-end processing chain of two-dimensional nanomaterials as part of its results. 2D materials integrated into mass production processes have the potential to create integrated and systemic product and production solutions that are socially, economically and ecologically sustainable. Application areas for the technologies developed and materials investigated in this project are mainly composite materials and coatings, highly sensitive sensors, power generation and storage, electronics, information and communication technologies as well as photonics and quantum technologies.

Graphmatech launches new graphene-enhanced conductive processable composite material

Sweden-based startup Graphmatech announced the launch of a new graphene-enhanced composite material. The new product, called Aros Create, is made of Nylon Aros Graphene pellets with a volume resistivity of less than 1 Ωcm while maintaining polymer lightweight, flexibility, processability, and recyclability.

The new composite may be used for extrusion, compression molding and injection molding and reportedly has unique electrical and tribological properties (low and stable coefficient of friction and high wear resistance). The potential applications are diverse, but the company's main focus is on electrical circuit components, LED, conductive coatings, additive manufacturing, EMI / RFI shielding, and charge dissipative coatings.

Graphene enables researchers to control infrared and terahertz waves

Researchers from the University of Geneva (UNIGE) in Switzerland and the University of Manchester in the UK have found an efficient way to control infrared and terahertz waves using graphene. "There exist a class of the so-called Dirac materials, where the electrons behave as if they do not have a mass, similar to light particles, the photons," explains Alexey Kuzmenko, a researcher at the Department of Quantum Matter Physics in UNIGE's Science Faculty, who co-conducted this research together with Ievgeniia Nedoliuk.

The interaction between graphene and light suggests that this material could be used to control infrared and terahertz waves. "That would be a huge step forward for optoelectronics, security, telecommunications and medical diagnostics," points out the Switzerland-based researcher.
