Electroforming Thin Fe Foils Using ChCl/Urea Deep Eutectic Solvent: Effects of MnCl2 and Current Density on Microstructure and Corrosion Behavior

MetalMat, EarlyView.
This study reports the electroforming of Fe thin foils using ChCl/urea DES. It analyzes the effect of current density and MnCl2 addition in the electroformed samples’ composition and corrosion behavior. It presents new insights into Mn incorporation via Fe₂O₃ doping in the Fe matrix.

On the Convergence of Conjugate Gradient and GMRES Algorithms in the Forward Backward Sweep Method for Optimal Control

Optimal Control Applications and Methods, EarlyView.
Optimal control combines state and adjoint equations, which yield the state (x$$ x $$) and adjoint (lambda) variables as a function of the control variables (u$$ u $$). This structure allows us to design strategies for iteratively updating the control variable, based on conjugate gradient (CG) or GMRES algorithms.

Applying Dynamics/Cost Parameter Continuation to the Optimal Guidance of Variable‐Speed Unicycle

Optimal Control Applications and Methods, EarlyView.
(a) Classical parameter continuation method diverges. (b) Dynamics/cost parameter continuation method converges. ABSTRACT The problem of a variable‐speed unicycle guidance to the stationary target is considered. The vehicle should be guided to the origin while minimizing the energy loss due to the induced drag.

Mesoporous Hollow Carbon Spheres/Nanofibers Anchored With Conductive Bimetallic for Efficient Microwave Absorption

Rare Metals, EarlyView.
ABSTRACT To break electromagnetic wave absorption (EMA) tech's single‐attenuation bottleneck, enhancing multi‐wave absorption synergy in composites is key for microstructure design. This study uses mesoporous hollow carbon spheres to make metal nanospheres with cobalt, iron, and nickel nanoparticles, then encapsulates them via electrospinning into a ...

Multi‐Functional S‐HA/ASTA NPs Coating on Biodegradable ZE21B Alloy for Cerebrovascular Applications

Rare Metals, EarlyView.
ABSTRACT Magnesium (Mg) and its alloys have attracted extensive attention of researchers in the field of cerebrovascular implants due to their good mechanical properties and biosafety. However, rapid degradation and delayed endothelialization pose challenges. To address these issues, this study introduces a multifunctional composite coating.
