Influence of Mn on Cementite Coarsening and Ferrite Grain Growth During Annealing of a Cold Rolled Medium Carbon Steel

To improve the formability of cold‐rolled medium carbon steels, the grain growth of ferrite with pinning of cementite particles during soft‐annealing was investigated through experiments and simulations in a hypoeutectoid Fe–0.29 mass%C–0.51 mass%Mn steel.Between the annealing times of 1.8 × 10 4 (5 h) and 3.6 × 10 5 s...

Code and data for: When may spray-capture models treat droplets as well mixed? A criterion and a surface-loading closure

MATLAB code and saved results for the paper "When may spray-capture models treat droplets as well mixed? A criterion and a surface-loading closure" by Ali M. Sefidan. The code resolves reaction and diffusion inside a single droplet of aqueous monoethanolamine (MEA) absorbing CO2. Carbamate formed near the interface dif...

Stability and Control of Fractional-Order Fuzzy Stochastic Clifford-Valued Neural Networks with Hybrid Markovian Switching, Cyber-Attacks, and Event-Triggered Multi-Agent Synchronization

We develop a rigorous stability and control theory for a class of Caputo fractional-order, Takagi–Sugeno (T–S) fuzzy, Itô stochastic, Clifford-valued neural networks (FFSCNNs) operating as agents of a leader–following multi-agent system. The model simultaneously incorporates (i) a Clifford (geometric) algebra state spa...

Optical tracking of mixed ionic-electronic transport in conjugated polymers

While OMIECs are widely used for bioelectronics, the dynamic relationship between ionic and electronic transport in these materials is generally poorly understood, hindering the rational design of new materials. To investigate mixed charge transport in detail, we developed an optical method to monitor electrochemical (...

Avenyra Geometric Memory Physics: Complete Spectral Certificates, Exact Tomography, and Correlation-Resolved Probe Survival in an Endogenous Memory Controller

Avenyra Geometric Memory Physics v3.0.0 develops a mathematical-physics framework for a controller in which accumulated geometric history changes the space of permitted future motion. It connects an exact signed-area update to spectral ordering, reconstructible observables, stochastic evolution, passive probe survival,...

Microstructural evolution, boride layer growth kinetics, and activation energy of dual-activator borided AISI 1040 steel

This study investigates the microstructural evolution, boride layer growth kinetics, and activation energy for boron diffusion in AISI 1040 steel borided using a dual-activator medium. Boriding was performed at 1173, 1223, and 1273 K for 2, 4, and 6 h. The phase composition of the boride layers was characterized by X-r...
