Machine learning reveals 5-angstrom sweet spot behind metallic glass stability

Using the second-nearest neighboring atoms to predict metallic glass stability can help researchers more accurately model the disordered solid with strong, elastic properties, according to a recent study led by University of Michigan Engineering researchers. The disordered atomic structure of metallic glasses creates a unique combination of high strength and elasticity but obscures which features control performance. Two machine learning approaches independently identified the same 5-angstrom (Å) radius as the most important to material properties. The study is published in the journal npj Computational Materials. While ductile metallic glass has been molded into components of consumer electronics, medical devices, high-end sports equipment and even spacecraft, expensive processing limits its use to these specialized applications. Understanding patterns in how the atomic structure of metallic glass impacts material properties can help researchers discover new, less costly metallic glasses for more widespread use.

Chaos as a matter of direction: Researchers build layered material where order and disorder coexist

Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, as in glass? Researchers at the University of Twente have now created a material that is both simultaneously. In two directions it is disordered; in the third, perfectly ordered. Their findings have been published in Nature Communications. In materials science, the distinction between crystalline and amorphous has been fundamental for more than a century. Crystals such as salt or diamond have a strictly repeating atomic pattern. Amorphous materials such as glass lack that long-range order. "We use that distinction every day," says Mark Huijben, a researcher at the University of Twente. "But we often assume that order or disorder is a property of the whole material. Our work shows it can also be a matter of direction."

Is glass a solid or a super slow liquid? Physicists create equilibrium glassy phase from rod-shaped particles

Glass appears to be a solid, but in theory it sometimes behaves more like an extremely slow liquid. Physicists in Utrecht now show that glass-like structures can also exist in equilibrium, which is something many theories say should be impossible. The bottom parts of medieval window panes, such as those in old cathedrals, are often thicker than the top. Has the material slowly flowed downward over the centuries, and does this mean that glass actually flows? This is a persistent myth, and the explanation lies in the way glass was produced in the Middle Ages. Because window panes were made by hand, their structure was often irregular and contained thinner and thicker parts. The panes were usually installed in the frame with the thicker side at the bottom, which made them more stable. Still, the story touches on a real physics question. What glass actually is, a solid or a very slow liquid, turns out to be more difficult to answer than it seems.

Coupling Pt Single-Atoms with Amorphous LDH Nanosheets as a High-Efficiency Sonosensitizer for Sonodynamic Immunotherapy - Research

Sonodynamic therapy (SDT) represents a minimally invasive alternative for cancer treatment. However, its efficacy is constrained by the insufficient reactive oxygen species generation of inorganic sonosensitizers due to wide bandgaps, rapid electron-hole recombination, and insufficient oxygen adsorption/activation. Herein, we report for the first time a novel sonosensitizer constructed by…

Establishing design principles for achieving ultralow thermal conductivity via controlled chemical disorder

A major challenge in thermal-management and thermal-insulation technologies, across multiple industries, is the lack of materials that simultaneously offer low thermal conductivity, mechanical robustness, and scalable fabrication routes. Discovering materials that exhibit completely insulating thermal behavior—or, conversely, extraordinarily high thermal conductivity—has long been a dream for researchers in materials physics. Traditionally, amorphous materials are known to possess very low thermal conductivity. This naturally leads to an important question: Can a crystalline material be engineered to achieve thermal conductivity close to that of an amorphous solid? Such a material would preserve the structural stability of a crystal while achieving exceptionally low thermal conductivity.
