Directa Plus announces grant to develop graphene paints and coverings

Directa Plus has been awarded a €136,000 grant from the Italian region of Lombardy to develop paints and coverings with its G+ graphene nano-platelets. “This grant from the Lombardy local government will help fund Directa Plus to develop these potentially disruptive products in a faster timeframe than we could have achieved using our own resources,” said founder and chief executive Giulio Cesareo in a statement.

Directa has created a new technology, called Grafyshield, a granular, semi-finished G+ formulation for the coatings market. Grafyshield is “designed to be easy to handle and mixable with resins using mixing equipment,” the producer and supplier of nano-platelets-based products said. The target for the new formulation is to bring anti-corrosion and flame-retardant properties to the final paint system.

Graphene oxide could help harvest ocean osmotic energy

Researchers from Deakin University's Institute for Frontier Materials (IFM) aim to harness the ocean's potential for renewable and clean energy. In a recent study, they demonstrated how a two-dimensional (2D) nanomaterial membrane technology can improve blue energy harvesting processes. Blue energy harvesting is renewable energy that uses the salt content difference between river water and seawater to generate electricity.

"Ocean energy is made up of five forms—tidal, water waves, ocean currents, temperature gradients and salinity gradient energy, offering a potential alternative, limitless energy resource," says Associate Professor Weiwei Lei, who is leading the sustainable energy generation project at IFM. "Therefore, harvesting ocean energy through artificial devices has attracted tremendous interest. In particular, salinity gradient energy, also called 'osmotic energy' or 'blue energy,' provides significant promise for the development of renewable energy. It has a potential 1 TW energy (8500 TW h in a year), which exceeds the sum of hydraulic, nuclear, wind and solar energy in 2015. With the development of nanotechnology and 2D nanomaterials, novel 2D nanomaterials' membranes with nanopores and nanochannels were designed for blue energy harvesting. However, the energy harvesting efficiency of these membranes is still too low to meet the demands of practical applications due to their high internal resistance and low selectivity of ions. New advanced 2D nanomaterial membranes with novel and robust properties will solve this problem, which is in high demand now."

Researchers construct artificial graphene nanoribbons to study behavior of electrons

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory (ANL) have created a novel testbed to explore the behavior of electrons in a special class of materials called topological insulators, which could see applications in quantum computing.

in previous work, graphene nanoribbons — small strips of graphene — were shown to exhibit promising topological states. Inspired by this, the Argonne team constructed an artificial graphene testbed with atomic precision in hopes to further explore those topological effects.

University of Manchester strikes graphene partnership with Khalifa University

The University of Manchester has entered a partnership with Abu Dhabi-based Khalifa University of Science and Technology, with the aim to deliver a funding boost to graphene innovation. Professor Dame Nancy Rothwell, President & Vice-Chancellor of The University of Manchester, and Professor Sir John O’Reilly, President of Khalifa University  officially signed a contract between the two institutions during a VIP visit by a Manchester delegation to the United Arab Emirates (UAE). 

This international partnership will further accelerate Manchester and Abu Dhabi’s research and innovation into graphene and other 2D materials. The Research & Innovation Center for Graphene and 2D Materials (RIC-2D), based in Khalifa University, is part of a strategic investment program supported by the Government of Abu Dhabi, UAE. This partnership will expedite the development of the RIC-2D at Khalifa University as well as help building capability in graphene and 2D materials in collaboration with Graphene@Manchester, a community that includes the academic–led National Graphene Institute (NGI) and the commercially-focused Graphene Engineering Innovation Centre (GEIC), a pioneering facility already backed by the Abu Dhabi-based renewable energy company Masdar.

Researchers develop graphene-enabled single fiber actuator inspired by human muscles

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) and Pusan National University in South Korea recently developed a graphene-enhanced  actuator for robotics applications, that is inspired by mammalian skeletal and muscle structures. The new actuator is based on soft fibers with strong contractive actuation properties.

The team explained that they based their work on liquid crystal elastomer (LCE) actuators, promising soft actuator materials with unusually large reversible dimensional change (shrink/relaxation) upon actuation, which is rarely observed in other kinds of actuator materials but highly significant to ideally mimic natural skeletal muscle behavior. Many actuators developed in the past are based on LCE materials, a class of polymers that can rapidly change shape in response to environmental stimuli. Despite their shape-morphing advantages, LCE polymers are known to be associated with the relatively poor mechanical properties and weak actuation behavior. To overcome this limitation, the researchers incorporated graphene fillers within the LCE actuators. In addition to enhancing their mechanical properties, the team expected the graphene fillers to enable light-driven, rapid and remotely controllable actuation, owing to the photothermal conversion capability of graphene.
