Researchers develop graphene-based battery-free lactic acid sensor

Scientists at the University of Bath, working in collaboration with Integrated Graphene, have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power. The new design potentially offers lower cost, better shelf-life, and ease of miniaturization compared to enzyme-based sensors. This could open up the possibility for an easy-to-use sensor to be used in remote locations, such as an athletics track, without the need for electricity-powered sensing equipment.

The sensor was able to detect lactic acid, a by-product generated by the body when it metabolizes carbohydrates or glucose for fuel, for example, during exercise. High levels of lactic acid are linked with higher risks of falling unconscious or into a coma and major organ failure.

Researchers enhance superconductivity of graphene-calcium superconductors

Researchers from Japan's Tokyo Institute of Technology and Institute for Molecular Science recently investigated the impact of high-density Ca introduction to C6CaC6 - a graphene-calcium compound which exhibits high critical temperature. In this compound, a layer of calcium is introduced between two graphene layers in a process called intercalation. 

While this material already has high critical temperatures, some studies have shown that critical temperatures and therefore superconductivity can be further enhanced through the introduction of high-density Ca.

Researchers irradiate graphene with ions to learn about its electronic behavior

Researchers from the University of Illinois at Urbana−Champaign, Sandia National Laboratories, and the University of Duisburg-Essen have shown that when graphene is irradiated with ions, the electrons that are ejected give information about its electronic behavior. 

Moreover, the Illinois group performed the first calculations involving high-temperature graphene, and the Duisburg-Essen group experimentally verified the predictions by irradiation.

Levidian suggests graphene as solution to EV tire wear pollution

Levidian has suggested to use graphene as a way to address the environmental impact of tire wear in electric vehicles, as early-stage research it conducted showcases promising results in leveraging high-quality graphene to mitigate environmental concerns linked to tire wear in EVs.

The heavier weight and greater torque of EVs has been shown to accelerate tire degradation, leading to increased rubber particulates that contaminate the environment. The widespread adoption of silica-filled compounds in tire treads, aimed at improving abrasion properties, can exacerbate the issue by causing faster migration of toxic anti-ozonant additives, particularly 6PPD.

Researchers detect current whirlpools in graphene at room temperature

Researchers from ETH Zurich in Switzerland and National Institute for Materials Science in Japan have used a nanoscale scanning magnetometer to image a distinctive hydrodynamic transport pattern—stationary current vortices—in a monolayer graphene device at room temperature. 

By measuring devices with increasing characteristic size, the team observed the disappearance of the current vortex and thus verified a prediction of the hydrodynamic model. they further observed that vortex flow is present for both hole- and electron-dominated transport regimes but disappears in the ambipolar regime.
