Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

Advanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Dynamic Testing of Cold Gas Sprayed Bipolar Plates–Porous Transport Layer Coating System in Proton Exchange Membrane Water Electrolysis

Advanced Engineering Materials, EarlyView.
Through direct application of porous transport layer (PTL) on the bipolar plate (BPP) with thermal spraying, the interfacial contact resistance is improved. With the cold gas sprayed BPP–PTL coating system, a proton exchange membrane water electrolysis cell with a cell voltage of Ucell = 1.9 V can be operated up to i = 2.5 A/cm2 in a dynamic mode ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Modelling and optimization of Ge/GaAs uni-travelling carrier photodiodes

Scientific Reports
Uni-Travelling-Carrier Photodiodes (UTC-PDs) are pivotal for the advancement of high-speed optical communication systems. Current UTC-PDs have a trade-off between high performance and low production costs. The performance of conventional Ge/Si UTC-PDs is

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

Advanced Engineering Materials, EarlyView.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.
