Huawei continues the use of graphene cooling films in its new P40 series

Huawei has launched its Huawei P40 flagship phone family, that includes three different devices: the Huawei P40, Huawei P40 Pro and, a new addition to the line-up for 2020, the Huawei P40 Pro Plus.

After many rumors about this line sporting a graphene battery - which were later disproved - it appears that Huawei's new P40 phones are using a graphene film cooling technology for heat management purposes (Huawei's SuperCool system), much like the Mate 20X and P30 line that preceded the P40.

Crumpled graphene could enable fast, simple and sensitive biosensors

Researchers at the University of Illinois at Urbana-Champaign have found that crumpling graphene makes it more than ten thousand times more sensitive to DNA by creating electrical "hot spots". This discovery could assist in addressing a known issue of graphene-based biosensors - the face that they require a lot of DNA in order to function properly.

"This sensor can detect ultra-low concentrations of molecules that are markers of disease, which is important for early diagnosis," said study leader Rashid Bashir, a professor of bioengineering and the dean of the Grainger College of Engineering at Illinois. "It's very sensitive, it's low-cost, it's easy to use, and it's using graphene in a new way."

A new graphene-carbon nanotubes hybrid catalyst could help clean energy revolution

Researchers at Aalto University, collaborating with researchers at CNRS France, have developed a graphene-carbon nanotube catalyst which gives better control over important chemical reactions for producing green technology and clean energy.

The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are the most important electrochemical reactions that limit the efficiencies of hydrogen fuel cells (for powering vehicles and power generation), water electrolyzers (for clean hydrogen production), and high-capacity metal-air batteries. The team has developed a new catalyst that reportedly drives these reactions more efficiently than other bifunctional catalysts currently available. The researchers also found that the electrocatalytic activity of their new catalyst can be significantly altered depending on choice of the material on which the catalyst was deposited.

Graphene-based platform could selectively identify deadly strains of bacteria

A team led by Boston College researchers has used a sheet of graphene to track the electronic signals inherent in biological structures, in order to develop a platform to selectively identify deadly strains of bacteria. This effort could lead to more accurate targeting of infections with appropriate antibiotics, according to the team.

The prototype demonstrates the first selective, rapid, and inexpensive electrical detection of the pathogenic bacterial species Staphylococcus aureus and antibiotic resistant Acinetobacter baumannii on a single platform, said Boston College Professor of Physics Kenneth Burch, a lead co-author of the paper.

Researchers create a graphene-based supercapacitor with the highest energy density ever

Researchers from the University College London designed new graphene-based supercapacitor materials that enable higher power density than current designs. The new materials also enables the production of bendable supercapacitors, without a liquid electrolyte which minimizes explosion risk.

The researchers say the new supercapacitor design can achieve an energy density of 88.1 Wh/L - the highest ever reported for carbon-based supercapacitors. The main innovation is the production of electrodes made from multiple layers of graphene, that enable a dense but porous material.
