Graphine paper 10 times stronger than steel

By Jeff Hughes Published April 21, 2011

Scientists at the University of Technology Sydney have developed a new graphene paper, a composite material made from processed graphite that is as thin as paper but is stronger than steel.

The UTS research team’s breakthrough with the material is the result of their unique production and heat testing method which found out these exceptional properties for the graphene paper.

The research team, supervised by Professor Guoxiu Wang, took raw graphite, purified it, filtered it with chemicals and pressed it into sheets. The graphene paper not only has ten times the strength of steel but is extremely flexible, is two times as hard and six times lighter with lower density. The graphene nanostack sheets also vaunt excellent thermal, electrical and mechanical properties.

Ali Reza Ranjbartoreh, the lead researcher on the team said, “ Not only is it lighter, stronger, harder and more flexible than steel it is also a recyclable and sustainable manufacturable product that is eco-friendly and cost effective in its use.”

The properties and promises of the graphene paper make it seem like a dream material. Indeed, it holds much potential for the automotive and aviation industries. Ranjbartoreh went on to say that the use of the graphene material would allow companies to create lighter and stronger cars and planes which would be more fuel efficient and eco-friendly. These improvements would be cost favorable for both consumers and companies alike.

A jump to the graphene paper wouldn’t be so large for aerospace companies such as Boeing who have already replaced metal with carbon-based materials. Austrialia, the country where the research was conducted, is home to plenty of the raw graphite and would welcome the boost to their industry from the graphene paper production.

Range Rover’s first electric SUV has 48,000 pre-orders

Land Rover Range Rover Velar SVAutobiography Dynamic Edition

Range Rover, the brand made famous for its British-styled, luxury, all-terrain SUVs, is keen to show it means business about going electric.

And, according to the most recent investor presentation by parent company JLR, that’s all because Range Rover fans are showing the way. Not only was demand for Range Rover’s hybrid vehicles up 29% in the last six months, but customers are buying hybrids “as a stepping stone towards battery electric vehicles,” the company says.

BYD’s cheap EVs might remain out of Canada too

BYD Han

With Chinese-made electric vehicles facing stiff tariffs in both Europe and America, a stirring question for EV drivers has started to arise: Can the race to make EVs more affordable continue if the world leader is kept out of the race?

China’s BYD, recognized as a global leader in terms of affordability, had to backtrack on plans to reach the U.S. market after the Biden administration in May imposed 100% tariffs on EVs made in China.

Tesla posts exaggerate self-driving capacity, safety regulators say

The National Highway Traffic Safety Administration (NHTSA) is concerned that Tesla’s use of social media and its website makes false promises about the automaker’s full-self driving (FSD) software.
The warning dates back from May, but was made public in an email to Tesla released on November 8.
The NHTSA opened an investigation in October into 2.4 million Tesla vehicles equipped with the FSD software, following three reported collisions and a fatal crash. The investigation centers on FSD’s ability to perform in “relatively common” reduced visibility conditions, such as sun glare, fog, and airborne dust.
In these instances, it appears that “the driver may not be aware that he or she is responsible” to make appropriate operational selections, or “fully understand” the nuances of the system, NHTSA said.
Meanwhile, “Tesla’s X (Twitter) account has reposted or endorsed postings that exhibit disengaged driver behavior,” Gregory Magno, the NHTSA’s vehicle defects chief investigator, wrote to Tesla in an email.
The postings, which included reposted YouTube videos, may encourage viewers to see FSD-supervised as a “Robotaxi” instead of a partially automated, driver-assist system that requires “persistent attention and intermittent intervention by the driver,” Magno said.
In one of a number of Tesla posts on X, the social media platform owned by Tesla CEO Elon Musk, a driver was seen using FSD to reach a hospital while undergoing a heart attack. In another post, a driver said he had used FSD for a 50-minute ride home. Meanwhile, third-party comments on the posts promoted the advantages of using FSD while under the influence of alcohol or when tired, NHTSA said.
Tesla’s official website also promotes conflicting messaging on the capabilities of the FSD software, the regulator said.
NHTSA has requested that Tesla revisit its communications to ensure its messaging remains consistent with FSD’s approved instructions, namely that the software provides only a driver assist/support system requiring drivers to remain vigilant and maintain constant readiness to intervene in driving.
Tesla last month unveiled the Cybercab, an autonomous-driving EV with no steering wheel or pedals. The vehicle has been promoted as a robotaxi, a self-driving vehicle operated as part of a ride-paying service, such as the one already offered by Alphabet-owned Waymo.
But Tesla’s self-driving technology has remained under the scrutiny of regulators. FSD relies on multiple onboard cameras to feed machine-learning models that, in turn, help the car make decisions based on what it sees.
Meanwhile, Waymo’s technology relies on premapped roads, sensors, cameras, radar, and lidar (a laser-light radar), which might be very costly, but has met the approval of safety regulators.
