Composition‐Tuned Enhancement of the Anomalous Nernst Effect in FeCo–Pt Thin Films on Rigid and Flexible Substrates

Advanced Engineering Materials, EarlyView.
Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Unraveling the Effect of Tramp Elements on Phase Transformations in Steels by Combining CALPHAD Modeling and Experiments

Advanced Engineering Materials, EarlyView.
This study investigates how tramp elements from increased scrap usage influence phase transformations in low‐alloyed steel. Combining dilatometry and microscopy reveal that tramp elements delay transformations, reduce critical cooling rates and increase hardenability.

Relativistic lattice Boltzmann methods: Theory and applications [PDF]

Physics Reports, 2020
We present a systematic account of recent developments of the relativistic Lattice Boltzmann method (RLBM) for dissipative hydrodynamics. We describe in full detail a unified, compact and dimension-independent procedure to design relativistic LB schemes capable of bridging the gap between the ultra-relativistic regime, $k_{\rm B} T \gg mc^2$, and the ...

Stacking‐Engineered Magnonic Topology and Transport in Honeycomb Homobilayers

Advanced Functional Materials, EarlyView.
ABSTRACT Topological magnons have emerged as a promising platform for dissipationless bosonic transport. However, a straightforward and effective strategy to engineer such topological states in real materials has yet to be fully realized. Here, a general scheme for controlling magnonic topological states via stacking engineering in van der Waals ...

Discretization of the velocity space in solution of the Boltzmann equation

, 1997
We point out an equivalence between the discrete velocity method of solving the Boltzmann equation, of which the lattice Boltzmann equation method is a special example, and the approximations to the Boltzmann equation by a Hermite polynomial expansion ...

Entropic lattice Boltzmann methods: A review

Computers & Fluids, 2023
في أواخر التسعينيات وأوائل عام 2000، كان مفهوم نظرية H المنفصلة ووظائف Lyapunov كوسيلة لضمان استقرار حلال بولتزمان المشابك تحولًا في النموذج في بناء حلالين حركيين منفصلين وفتح الباب أمام مناقشات ووجهات نظر جديدة حول هذه المسألة. اقترح البناء الإنتروبي إعادة تنظيم مشغل تصادم الاسترخاء عن طريق تغيير كل من جاذب التوازن وعملية الاسترخاء من خلال إدخال ...
