In a new record for auxetic materials, researchers at the University of Western Ontario synthesized 2D flakes of tungsten semicarbide than can expand up to 40% under applied strain.

Plastic deformation of polycrystalline ceramics at room temperature is hindered by the lack of sufficient independent slip systems within the material’s structure. Researchers in Germany circumvented this limitation by focusing on deformation in the near-surface region, which demonstrates several useful dislocation mechanisms not available in the bulk region.

The emergence of large language models has the potential to greatly accelerate data extraction from materials science literature, but annotating the text before extraction is often still a manual task. Researchers led by Taylor Sparks at the University of Utah developed a new method that harnesses the power of Google’s Gemini Pro to reduce the need for manual annotation.

Optical devices traditionally require numerous layers to guide and transform light to achieve the desired result. Researchers at The Ohio State University showed that only a single layer of epsilon-phase tungsten trioxide, which they just experimentally confirmed is ferroelectric, can be used to create color-changing smart windows.

Materials that can display superconductivity are extremely rare in nature, and to date, no naturally occurring mineral was known to display unconventional superconductivity. Researchers led by Ames National Laboratory discovered that miassite, which previously was identified as a superconductor, actually displays unconventional superconductivity.

Successful plastic deformation of nitride ceramics has to date been limited to samples on the micro and nanoscale. Now, researchers from Yanshan University in China achieved plastic deformation in a bulk boron nitride ceramic by modifying its layered van der Waals structure.

Achieving long-term operational stability of all-perovskite solar cells remains a challenge. Researchers led by Georgia Institute of Technology made the surprising discovery that while exposing perovskites to both water and oxygen leads to instability, taking away one of those factors preserved the perovskites’ structure.

In July 2023, researchers announced the creation of high-strength, lightweight glass nanolattices by coating DNA origami scaffolds with silica. Their new open-access paper, published in January 2024, describes the functionalization of these glass-coated scaffolds by infiltrating the nanolattice with metal and metal oxide particles.

Fragility is a key glass property that helps manufacturers optimize processing parameters during glass fabrication. Measuring fragility, though, is a labor-intensive and time-consuming process. Identifying structural parameters that correlate with fragility could make predicting this property easier, and a new study led by Corning researchers reveals a correlation with the medium-range atomic ring structure.
