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.

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.

Australia-based energy storage solutions developer EnyGy has been working on a graphene-enhanced supercapacitor that can provide "increased energy storage capacity within the same package size,  known as enhanced energy density, enabling the realization of compact, fast energy storage", according to CEO Wiehann de Klerk.

The Company stated that the supercapacitor, called enyGcap, is currently undergoing trials, with a market launch expected in 2024.

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.

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.

Versarien has raised £454,822 before expenses (over USD$558,000) through a stock market placing as it continues its turnaround strategy.

Versarien said that net proceeds will be used for corporate and working capital purposes, together with providing bridge finance to extend the Company's cash runway ahead of any funds received from asset sales.

NanoXplore reported its financial results for Q3 2023. Total revenues were $28.9 million CAD, up 6% from last year. The net loss was $448,000 (compared to a loss of $1.97 million last year). The company's cash and equivalents at the end of the quarter was $39.5 million CAD. NanoXplore expects its revenues for the year ending June 30, 2024 to reach $130 million.

In September 2023 NanoXplore announced new business representing over $17 Million in annual sales. The company says its graphene initiatives are steadily growing and it is "well positioned to deliver the returns our shareholders are expecting from us".  NanoXplore's graphene enhanced composite light weighting solutions are gaining momentum, and more OEMs are interested in its products. 

Researchers at the Indian Institute of Technology (IIT) Guwahati have developed cost-effective experiments for modifying graphene oxide (GO) that can be used by other academic institutions to train personnel needed for cutting-edge projects in semiconductors, nanoelectronics, healthcare and quantum technologies.

A team led by Rajiv K Kar, assistant professor, at the Jyoti and Bhupat Mehta School of Health Sciences and Technology in IIT-Guwahati, made these discoveries regarding the use of modified graphene oxide for biomedical applications, according to a recent announcement.

Versarien has announced the launch of a portfolio of graphene and related nanomaterial-based thermoplastic polymer compounds, branded under the name Polygrene. The Company says that the Polygrene line is the culmination of extensive collaborative efforts with the International Institute for Nanocomposites Manufacturing (IINM) at WMG, University of Warwick.

The new range has potential applications across a variety of industries, including sports equipment, construction products, aerospace and automotive components. This versatility showcases the adaptability and strength of the new graphene-infused materials.

A research team, led by The University of Manchester, have reported a way to use light to accelerate proton transport through graphene, which could advance hydrogen generation technologies.

Proton transport is a key step in many renewable energy technologies, such as hydrogen fuel cells and solar water splitting, and it was also previously shown to be permeable to protons. The recent study has shown that light can be used to accelerate proton transport through graphene, despite the fact that it was previously thought that graphene was impermeable to protons. The researchers found that when graphene is illuminated with light, the electrons in the graphene become excited. These excited electrons then interact with protons, accelerating their transport through the material.
