University of California, Irvine scientists recently discovered a one-dimensional nanoscale material whose color changes as temperature changes. The team’s results appeared in Advanced Materials (“Sensitive Thermochromic Behavior of InSeI, a Highly Anisotropic and Tubular 1D van der Waals Crystal”).

“We found that we can make really small and sensitive thermometers,” said Maxx Arguilla, UC Irvine professor of chemistry whose research group led the study. “It’s one of the most applied and translatable works to come out of our lab.”

Arguilla likened the thermometers to “nanoscale mood rings,” referring to the jewelry that changes color depending on the wearer’s body temperature. But instead of simply taking a qualitative temperature reading, the changes in the color of these materials “can be calibrated and used to optically take temperature readings at the nanoscale,” Arguilla said.

James Cook University researchers have achieved a significant breakthrough that allows them to convert microplastics to a highly valuable material. The study is published in the journal Small Science.

A new material can withstand ‘billions’ of electrical cycles without wearing out — and scientists say it could transform electronics within 10 to 20 years.

The first materials scientists might have been early humans who—through trial-and-error experiments—discovered the first “cutting-edge” technologies. They found that the best arrowheads and other tools could be made from certain types of natural, structural materials, which at the time included stones and animal bones.

A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto “dying to align”: Misaligned filaments “die” spontaneously to form a ring structure at the center of the dividing cell. The study, led by the Šarić group at the Institute of Science and Technology Austria (ISTA), was published in Nature Physics. The work could find applications in developing synthetic self-healing materials.

Atomic-scale 2D magnets can be polarized to represent binary states — the 1s and 0s of computing data. These can lead to far more dense and energy-efficient components.

Two teenagers won $50,000 for creating an ultrasonic microplastics filter, offering hope in the fight against plastic pollution.

The body is pretty good at repairing itself, but some parts of our anatomy struggle to bounce back after an injury.

One such material is cartilage – the spongy yet firm connective tissue that keeps our bones from rubbing and jarring against each other. Over time, the translucent or ‘hyaline’ components of cartilage can become heavily degraded, resulting in painful conditions like osteoarthritis and chondromalacia.

Scientists have been working on a way to regenerate hyaline cartilage for years, and now a team led by Northwestern University in the US has achieved a breakthrough. They have developed a biomaterial that, injected into damaged cartilage in living sheep, acted as a scaffold that promoted cartilage regrowth in active joints.

Fascinating study!

A new study suggests that cloud-to-ground lightning likely provided the necessary material for the first organisms on Earth to form.
