Bioinspired protein creates stretchable 2D layered materials

27-Jul-2022

Nature creates layered materials like bone and mother-of-pearl that become less sensitive to defects as they grow. Now researchers have created, using biomimetic proteins patterned on squid ring teeth, composite layered 2D materials that are resistant to breaking and extremely ...

New method purifies hydrogen from heavy carbon monoxide mixtures

Licensing the technology for a start-up

11-Apr-2022

Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. A research team led by Chris Arges, Penn State ...

Salvaging rare earth elements from electronic waste

Chemical engineer develops sustainable nanotechnology to selectively recover metals

25-Nov-2021

Manufacturers rely on rare earth elements, like neodymium, to create strong magnets used in motors for electronics including hybrid cars, aircraft generators, loudspeakers, hard drives and in-ear headphones. But mineral deposits containing neodymium are hard to reach and are found in just a few ...

Self-healing soft material outsmarts nature

New stretchable material entirely recovers its structure and properties at the blink of an eye – and it can do this over and over again

30-Jul-2020

A soft material that heals itself instantaneously is now reality. A team of scientists at the Max Planck Institute for Intelligent Systems and at Pennsylvania State University tune the nanostructure of a new stretchable material in such a way that it now entirely recovers its structure and ...

A megalibrary of nanoparticles

A simple, modular chemical approach could produce over 65,000 different types of complex nanorods

28-Jan-2020

Using straightforward chemistry and a mix-and-match, modular strategy, researchers have developed a simple approach that could produce over 65,000 different types of complex nanoparticles, each containing up to six different materials and eight segments, with interfaces that could be exploited in ...

A new method to study lithium dendrites could lead to better, safer batteries

14-Jan-2020

Lithium ion batteries often grow needle-like structures between electrodes that can short out the batteries and sometimes cause fires. Now, an international team of researchers has found a way to grow and observe these structures to understand ways to stop or prevent their appearance. "It is ...

In and out with 10-minute electrical vehicle recharge

01-Nov-2019

Electric vehicle owners may soon be able to pull into a fueling station, plug their car in, go to the restroom, get a cup of coffee and in 10 minutes, drive out with a fully charged battery, according to a team of engineers. "We demonstrated that we can charge an electrical vehicle in ten minutes ...
