Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

Advanced Engineering Materials, EarlyView.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...

Power System Grid Planning with Distributed Generation

, 2021
Distributed Generation (DG) is one of the technologies approved by the South African government for the country's generation expansion to meet future load demand and to support economic growth. DGs change the conventional power flow (generation, transmission to distribution) by injecting real and reactive power at distribution voltage levels.
