Disintegration and Skipping Dynamics of Bilobate‐Shaped Meteoroids for Generating Ultra‐Long Strewn Fields

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution.

Microstructure, mechanical, and thermal properties of compositionally complex (Hf,Zr,Nb,Ti)B2‒LaB6 ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.
