Effect of Copper Content on the Microstructure and Mechanical Properties of As‐Cast Refractory MoNbTi Multiprincipal Element Alloys

Advanced Engineering Materials, EarlyView.
Copper addition profoundly impacts MoNbTi multiprincipal element alloys. This study reveals copper's dual role, promoting microstructural refinement and strengthening intermetallics at optimal concentrations. An ideal copper content significantly boosts hardness and compressive strength, achieving superior mechanical performance.

Non-equilibrium theories of rarefied gases: internal variables and extended thermodynamics

Continuum Mechanics and Thermodynamics, 2018
Limits of classical constitutive laws such as Fourier and Navier–Stokes equations are discovered since decades. However, the proper extensions—generalizations of these—are not unique.

(Nb,Ti)(C,N)‐Precipitates in High‐Strength Low‐Alloyed Steels—Modeling, Characterization and Validation

Advanced Engineering Materials, EarlyView.
Steel samples are investigated using complementary simulations and measurements. Transmission electron microscopy in bright‐field mode, combined with energy‐dispersive X‐ray spectroscopy maps for titanium and niobium, reveals distinct particle populations. Simulations reproduce these in size and composition.

Improved Strength and Corrosion Resistance of Ti–50Zr Alloy Through Heat Treatment

Advanced Engineering Materials, EarlyView.
This work systematically analyzes the effects of heat treatment on mechanical properties and corrosion behavior of Ti‐50Zr alloy produced via vacuum arc melting. Microstructure transforms from coarse lamellar α phase in as‐cast condition to fine and uniformly distributes acicular α′ phase in heat‐treatment state.

Steepest Entropy Ascent Model for Far-Non-Equilibrium Thermodynamics. Unified Implementation of the Maximum Entropy Production Principle

, 2014
By suitable reformulations, we cast the mathematical frameworks of several well-known different approaches to the description of non-equilibrium dynamics into a unified formulation valid in all these contexts, which extends to such frameworks the concept

A non-equilibrium thermodynamics model for combined adsorption and diffusion processesin micro- and nanopores [PDF]

, 2012
A non-equilibrium thermodynamics model able to analyze the combined effect of diffusion and adsorption in porous materials is proposed. The model considers the coupled dynamics of the diffusive phase, described by a diffusion type equation, and the ...

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Cosmological and thermodynamics analysis in Weyl gravity

European Physical Journal C: Particles and Fields, 2020
In the framework of modified Weyl gravity, we observe the equilibrium picture of the thermodynamical laws for flat Friedmann–Robertson–Walker metric with chameleon scalar field and analyze the validity of the generalized second law of thermodynamics and ...

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...
