Researchers develop bioinspired reinforced graphene membranes that overcome mechanical limitations

Researchers from Peking University, Beijing Normal University and KU Leuven recently reported a novel method to substantially reinforce large-area graphene membranes. Their work provides a facile method to fabricate large-area graphene membranes and paves the road to practical application in the membrane separation field. 

Nanoporous graphene membranes are attractive for molecular separations, but it remains challenging to maintain sufficient mechanical strength during scalable fabrication and module development. In this work, the team drew inspiration from the composite structure of cell membranes and cell walls, and designed a large-area atomically thin nanoporous graphene membrane supported by a fiber-reinforced structure with strong interlamellar adhesion. It was found that factors like fracture stress, fracture strength, and tensile stiffness of the composite membranes can be enhanced compared with other graphene-based membranes of large scale.

Will the iPhone 16 use graphene heat sink to solve overheating issues?

Rumors suggest that the iPhone 16 may use a graphene heat sink and a metal battery case to promote better heat transfer.

This follows complaints by iPhone 15 users about overheating, which Apple fixed via software, but the iPhone 16 is rumored to have a hardware solution, too. Apple associated the overheating with poorly optimized software and issued a software fix, but more effective cooling may also help.

Researchers develop DNA aptamer-attached portable graphene biosensor for the detection of degenerative brain diseases

An international team of researchers, including scientists from University of California San Diego, Chinese Academy of Sciences, University of Texas Medical Branch and University of Illinois Urbana-Champaign, has developed a handheld, non-invasive graphene-based device that can detect biomarkers for Alzheimer’s and Parkinson’s Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone.

The biosensor consists of a chip with a highly sensitive transistor, made of a graphene layer that is a single atom thick and three electrodes–source and drain electrodes, connected to the positive and negative poles of a battery, to flow electric current, and a gate electrode to control the amount of current flow.

The team tested the device on in vitro samples from patients. The tests reportedly showed the device is as accurate as other state-of-the-art devices. Ultimately, researchers plan to test saliva and urine samples with the biosensor. The device could be modified to detect biomarkers for other conditions as well.

Researchers develop antimony alloy based reduced graphene oxide composite for faster charging sodium-ion batteries

Researchers from the University of Hyderabad (UoH) and the Tata Institute of Fundamental Research (TIFR) have developed electrode materials made of Tin antimony alloy based reduced graphene oxide composite which has the potential to enhance energy storage for sodium-ion batteries.

Sodium-ion batteries could offer enhanced energy efficiency, rapid charging capabilities, resilience to extreme temperatures, and safeguards against overheating or thermal runaway incidents. They exhibit reduced toxicity due to their lack of reliance on lithium, cobalt, copper, or nickel, which have the potential to emit environmentally harmful gases in the event of fire, according to a recent official release.

New project called GRAPHERGIA to revolutionize energy harvesting in textiles and battery technology

A consortium of 11 partners from six European countries has launched the GRAPHERGIA project, an ambitious 3.5-year Research and Innovation program, funded by €4.5 million under the Horizon Europe's Graphene Flagship initiative.

Aimed at redefining the integration of energy solutions into everyday life, GRAPHERGIA aims to transform how we use and store energy. Its main goal is to develop and deploy cutting-edge graphene-based materials into energy harvesting and storage devices. These advances would enable scalable and cost-efficient production of two-dimensional (2D) material technologies for a wide array of applications.
