Plastic to metal, steel to aluminum: The future of welding and lightweight vehicles

via TechExplore

plastic manufacturing

Making vehicle structures out of a combination of metals and plastics could make them dramatically lighter, stronger, safer and more environmentally friendly than the all-steel or all-aluminum approaches that dominate today.

But how to quickly and cheaply join all those materials together has been a sticky problem. A University of Michigan lab is developing solutions.

New type of metallic plastic can be sprayed on and made from chains of polymers

via Interesting Engineering

Scientists at the Anderson Laboratory at the University of Chicago have discovered a metallopolymer that can be made into various shapes, and remains stable in almost any environment.

A plastic material has been discovered that has metallic properties and remains stable when chilled, heated, left out in the air, or exposed to acid. Researchers are saying it could prove valuable in medical devices that are wearable, or other kinds of wearable electronics.

Award-winning — plastic-eating robo-fish is finally here to rid our waters of waste

Award-winning — plastic-eating robo-fish is finally here to rid our waters of waste

via Interesting Engineering

A robot fish that filters microplastics has been created after winning a robotics contest at the University of Surrey.

Researchers in robotics make the “robo-fish” concept a reality, according to a press release published by the University on Thursday.

“Water pollution, especially plastic pollution, is a huge problem. It’s not just the ocean which suffers but rivers, streams, lakes, and ponds. This makes it a problem without a one-size-fits-all solution,” Eleanor Mackintosh, a chemistry undergrad student at the University of Surrey and the contest winner, told New Atlas.

Scientists Turn Plastic Into Diamonds In Breakthrough

Scientists Turn Plastic Into Diamonds In Breakthrough

plastic scrapThe production of nanodiamonds from PET plastic paves the way toward a new form of recycling, and even has implications for exoplanets that rain diamonds.

In 2017, researchers in Germany and California found a way to replicate those planetary conditions, fabricating teeny tiny diamonds called nanodiamonds in the lab using polystyrene (aka Styrofoam). Five years later and they’re back at it again, this time using some good ol’ polyethylene terephthalate (PET), according to a study published on Friday in Science Advances. The research has implications not only for our understanding of space, but paves a path toward creating nanodiamonds that are used in a range of contexts out of waste plastic.

Plastic-eating superworms with ‘recycling plant’ in their guts might get a job gobbling up waste

via SCMP Scientists from Australia’s University of Queensland have discovered that a type of beetle larvae called Zophobas morio can consume and break down polystyrene. Research published in the scientific journal Microbial Genomics on June 9, 2022, says the superworms possess special gut enzymes that can break down plastic. The researchers say they now hope to study the enzymes to engineer ways the substance could be used to break down and dispose of plastic waste in the future.

Scientists at the Vrije Universiteit Amsterdam (VUA) in the Netherlands found the particles in three-quarters of meat and milk products tested and every blood sample in their pilot study.

Scientists unveil bionic robo-fish to remove microplastics from seas

Scientists unveil bionic robo-fish to remove microplastics from seas

via The Guardian

Scientists have designed a tiny robot-fish that is programmed to remove microplastics from seas and oceans by swimming around and adsorbing them on its soft, flexible, self-healing body.

Microplastics are the billions of tiny plastic particles which fragment from the bigger plastic things used every day such as water bottles, car tyres and synthetic T-shirts. They are one of the 21st century’s biggest environmental problems because once they are dispersed into the environment through the breakdown of larger plastics they are very hard to get rid of, making their way into drinking water, produce, and food, harming the environment and animal and human health.
