Phase Separation and Mechanical Properties in Si‐Poor Sodium‐Borosilicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
We demonstrate an unexpected phase separation and the related mechanical property enhancements in a sodium‐borosilicate glass. ABSTRACT Phase separation is a well‐known approach to increase the damage tolerance of oxide glasses. Here, we report the separation of a silicon‐ and boron‐rich phase in a Si‐poor sodium‐borosilicate glass.

Linking Structural and Mechanical Properties to Multimodal Sensory Perception of Fibrousness in Plant‐Based Meat Analogs

Journal of Texture Studies, Volume 57, Issue 4, August 2026.
Macrostructural fiber alignment quantified by the image‐based Fiberlyzer method strongly predicts both perceived visible and oral fibrousness in plant‐based whole‐cut meat analogs. Integrating structural imaging, directional mechanics, and sensory analysis provides a robust framework to interpret and design fibrous texture independent of visual ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Atmospheric Noise Forcing Increases Multiyear El Niño Events

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Despite their pronounced climate impacts, the physical processes that control the frequency of multiyear El Niño events remain incompletely understood. Using an Interactive Ensemble (IE) coupling strategy, we find that atmospheric noise forcing plays an important role in modulating the frequency of multiyear El Niño events.
