Programmable Interfacial Energy Alignment in Plasmonic Metal‐Organic Frameworks for Selective Molecular Probing on Complex Heterogeneous Surfaces

open access: yesAggregate, Volume 7, Issue 8, August 2026.
A programmable plasmonic MOF–microgel SERS chip enables adaptive 3D interfacial coupling and energy level–wavelength dual selectivity on complex heterogeneous solids. It delivers nondestructive, spatially resolved identification and semiquantitative assessment of multiphase bronze corrosion from model stratigraphy to excavated artifacts.

Influence of Si Content and Milling Duration on the Microstructure and Mechanical–Tribological Properties of AlCoCrFeNiSi High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Si‐doped AlCoCrFeNi high‐entropy alloys are synthesized by mechanical alloying to reveal the effect of Si content and milling time on phase evolution, microstructural refinement, and tribological behavior. A transition from FCC to BCC structure, significant grain refinement, and enhanced hardness and wear resistance are achieved, with the 4 at% Si ...

Beyond Single‐Active Sites: The Emergence of High‐Entropy Perovskites in Energy and Environment Catalysis

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
This review examines high‐entropy perovskites (HEPs) as a promising catalyst platform for energy and environmental applications. The focus is on configurational entropy engineering, design and synthesis, and computational understanding. These materials possess tunable active sites, enhanced stability, and improved electronic interactions, leading to ...

None 炉心損傷事故の安全解析コードにおける多成分多相流の熱流動現象の数値シミュレーション技術の高度化を図ることは、安全評価の信頼度を向上する上で重要な課題の一つである。核燃料サイクル開発機構と九州大学によって実施された本共同研究では、炉心損傷事故(CDA)を解析する高速炉安全解析コードに適用可能な多成分系蒸発/凝縮現象の一般化モデルを新たに開発した。このモデルは、CDA条件下での多成分相変化現象を模擬するため、蒸発/凝縮過程の特性を熱伝達および質的拡散による律速モデルを用いて記述している。さらに、既存の多成分凝縮実験および新たに実施した気泡凝縮実験の解析によって、本モデルが非凝縮性ガスを含む蒸気の凝縮過程を適切に再現することを確認し、用いられたモデル化手法の妥当性を示した。
