Electrolyte gating uses ions to reversibly modify La0.5Sr0.5CoO3−δ, changing oxygen content and electrical, magnetic, and optical properties at 1–2 V. The team achieved ~100-cycle endurance with humidity control and 4 nm films switching in ~0.7 s. Prospects include tunable optics/photonics; future work targets diffusion and surface chemistry; collaborations.

Last summer, 12 high school students were challenged to identify a mystery polymer. As part of a summer internship—now in its second year—they visited the chemical giant Chemours where they gained access to high-tech lab equipment rarely open to the public and were provided with relevant clues and tests to help solve the puzzle. It’s as hands on as it gets and gave this young group valuable exposure to the world of STEM.

In the world of materials science, researchers are constantly seeking new ways to create more efficient, durable, and adaptable materials. One promising avenue is the study of bottlebrush block polymers, a unique class of macromolecules that self-assemble into intricate nanostructures. Researchers at the University of Minnesota have been at the forefront of this research, uncovering new possibilities for these polymers and their applications.

A class of synthetic soft materials called liquid crystal elastomers (LCEs) can change shape in response to heat, similar to how muscles contract and relax in response to signals from the nervous system. 3D printing these materials opens new avenues to applications, ranging from soft robots and prosthetics to compression textiles.

Nickel-based spinel oxides show exceptional self-lubrication at extreme temperatures, unlocking potential for aerospace and energy applications.

The reason microplastics are all around and even in us is because petroleum-based plastics last for hundreds of years. In our lifetimes they simply don’t go away. But degradable plastics, made from plants, do. Research at UCSD has now proven that those earth-friendly plastics disappear in a matter of a few months. Researchers ground up plant-based plastics into very small bits and tested them in several natural environments.

Helium may be the second-most abundant element in the universe, but on Earth it’s a finite, nonrenewable resource. Helium is so light that it’s not trapped by the lower levels of Earth’s atmosphere. And it’s extremely challenging to capture, since it’s relatively unreactive. Liquid helium is a critical ingredient in systems for cooling equipment used to study quantum systems and image atoms, as well as in the high-performance magnets used in MRI scanners and particle accelerators. But if it is not carefully contained, helium flies to the farthest reaches of the atmosphere or even out into space when it boils.

The University of Pennsylvania's MRSEC Director, Eric Stach was recently named the Scientific Director of the Singh Center for Nanotechnology. Stach’s distinguished career in materials science and engineering, specifically in transmission electron microscopy, combined with his extensive experience managing interdisciplinary research teams, positions him uniquely to lead the Singh Center towards new heights of achievement.

Northwestern Engineering’s Mark Hersam, whose research has led to more effective and sustainable nanomaterials used in electronics, energy storage, and medicine, has been elected to the National Academy of Engineering.

The Center for Dynamics and Control of Materials (CDCM) at UT Austin recently launched The Materials Universe Podcast, a show where researchers discuss the impact of materials science on our lives. Listen to interviews with CDCM researchers working on cutting-edge projects in areas such as nanomaterials, biomaterials, smart materials, and more. Learn about the latest discoveries and innovations in materials science, and how they can impact fields such as energy, medicine, electronics, and beyond.
