Bilayer nanographene system uses "defect" to allow ions to pass through

Würzburg University researchers have created a defect in graphene that allows ions to pass through, which could lead to new applications in water filtration or sensor technology.

Defects that allow scientists to control the permeability of graphene for different substances can be very useful: ‘So-called defects can be created in the carbon lattice of graphene. These can be thought of as small holes that make the lattice permeable to gases,’ says chemistry professor Frank Würthner from Julius-Maximilians-Universität (JMU) Würzburg in Germany.

ADNOC Gas and Baker Hughes install Levidian's LOOP technology at their operational gas processing plant

ADNOC Gas and Baker Hughes have installed Levidian’s LOOP technology at the Habshan Gas Processing Plant. The Gulf operator claims it marks the first-ever deployment of the technology at an operational gas processing site.

Carbon will be captured from methane, the main constituent of natural gas, and transformed into graphene, as part of a pilot trial. The LOOP unit is capable of producing more than 1 tonne per annum (tpa) of graphene and 1 tpa of hydrogen, making it a dual-purpose innovation aligned with global energy transition goals. Future industrial-scale installations are expected to deliver 15 tpa.

SmartIR’s graphene-based radiator launches on SpaceX Falcon 9

SmartIR, a University of Manchester spinout, has announced that graphene-based adaptive radiator has launched aboard SpaceX’s Falcon 9 Transporter-12 as part of Mission 2, a collaboration with Hydra Space and Alba Orbital.

This mission addresses a critical challenge in the space sector: the need for cost-effective thermal management solutions. Current low-orbit satellites often rely on heaters, which increase power consumption, while long-orbit satellites utilize heavy and bulky systems such as thermal louvres. SmartIR’s graphene-based radiator offers a solution to this problem, enabling satellites to flexibly manage thermal energy. The technology fully vents heat from all surfaces when in Earth’s shadow and selectively shields only the side exposed to the sun during orbit.

Researchers design PV-powered supercapacitor with high energy and power density

Researchers from Korea's DGIST, Kyungpook National University, France's University of Bordeaux (CNRS), Collège de France and Japan's Komaba Institute for Science (KIS) recently designed a solar-powered faradaic supercapacitor, with a graphene layer as its anode, that can reportedly achieve a power density of 2,555.6 W kg and an energy efficiency of 63%. The system uses nickel-based compounds to enhance the electrochemical performance of its electrodes.

To build these electrodes, the scientists used a nickel-based carbonate and hydroxide composite material, which are said to optimize their conductivity and stability. They initially tested transition metal ions such as manganese (Mn), carbon monoxide (Co), copper (Cu), iron (Fe), and zinc (Zn) and found that the optimal nanostructure of the electrodes depended on the transition metals used.

New graphene-based laser lift-off process enables ultrathin flexible displays

Researchers from Seoul National University of Science and Technology, Korea Advanced Institute of Science and Technology and Korea Institute of Machinery and Materials recently reported a graphene-based laser lift-off technique that prevents damage while separating ultrathin OLED displays. This advancement could open the door towards ultra-thin, stretchable devices that fit comfortably against human skin, revolutionizing wearable device technology.

Polyimide (PI) films are widely used in these applications due to their excellent thermal stability and mechanical flexibility. They are crucial for emerging technologies like rollable displays, wearable sensors, and implantable photonic devices. However, when the thickness of these films is reduced below 5 μm, traditional laser lift-off (LLO) techniques often fail. Mechanical deformation, wrinkling, and leftover residues frequently compromise the quality and functionality of ultrathin devices, making the process inefficient and costly.
