Oxide glasses are an elementary group of materials in modern society, but brittleness limits their wider usability at room temperature. As an exception to the rule, amorphous aluminum oxide (a-Al O ) is a rare diatomic glassy material exhibiting significant nanoscale plasticity at room temperature. Here, it is shown experimentally that the room temperature plasticity of a-Al O extends to the microscale and high strain rates using in situ micropillar compression.

- * Research reveals that amorphous aluminum oxide can deform without breaking at room temperature through a process called viscous creep, showing significant ductility.
- * This finding suggests the potential to create more durable glass materials, enhancing the performance and reliability of electronics and batteries.
Article Synopsis
- The paper explores small angle X-ray scattering (SAXS) as an effective method for measuring the size and distribution of TiO nanoparticles, which are synthesized via pulsed laser ablation in liquids.
- Transmission electron microscopy (TEM) revealed that the TiO nanoparticles are spherical, ranging from 4-35 nm, and primarily consist of anatase and rutile phases, with minor brookite presence, alongside confirmation of high crystallinity through X-ray diffraction.
- SAXS was found to be a reliable technique for characterizing nanoparticle size and distribution, showing similar trends to TEM measurements, despite SAXS yielding slightly larger diameter readings due to its measurement of particle agglomerates.
