Brazing ZrB2 ultra‐high‐temperature ceramics to Zr metals for hypersonic thermal protection systems
International Journal of Applied Ceramic Technology, EarlyView.Abstract Porous and dense zirconium diboride (ZrB2) materials are promising ultra‐high‐temperature ceramics (UHTCs) for transpiration cooling in hypersonic applications, providing an effective means to reduce component temperatures and mitigate oxidation effects. While porous ZrB2 enables coolant flow, dense ZrB2 offers structural integrity.

Journal of Metamorphic Geology, EarlyView.ABSTRACT To gain insights into the pressure–temperature evolution of a scarcely studied portion of the Variscan basement of Corsica in southern Europe, we combined phase equilibrium modelling, Zr‐in‐rutile thermometry and apatite‐in‐garnet elastic barometry. We investigated Grt‐St micaschist rocks containing garnet grains of several millimetres in size

Parallel computing aided analyses of dynamic buckling for railway track infrastructure
Computer-Aided Civil and Infrastructure Engineering, EarlyView.Abstract This paper presents a scalable parallel computing framework for simulating track buckling under dynamic train loads, enabling large‐scale railway track stability analysis. A three‐dimensional (3D) track model is developed using finite element‐based Euler–Bernoulli beam formulations for rails, dynamic force inputs, and nonlinear interactions at
