Influence of a Hydrogen Addition to the Inert Gas and Subsequent Heat Treatments on the Microstructure and Mechanical Properties of Magnesium WE43 Fabricated by PBF‐LB/M

Advanced Engineering Materials, EarlyView.
This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.

Fabrication of Compositionally Graded NiTi Shape Memory Alloy Laminated Composites Through Hot Roll Bonding and its Characterization

Advanced Engineering Materials, EarlyView.
A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Probing progression of heating through the lower flare atmosphere via high-cadence IRIS spectroscopy [PDF]

arXiv
Recent high-cadence flare campaigns by the Interface Region Imaging Spectrograph (IRIS) have offered new opportunities to study rapid processes characteristic of flare energy release, transport, and deposition. Here, we examine high-cadence chromospheric and transition region spectra acquired by IRIS during a C-class flare from 2022 September 25 ...

Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites

Advanced Functional Materials, EarlyView.
The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.

Facet‐Junction Induced Strong Metal Support Interaction for Enhanced Alkaline Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
In this study, a novel facet‐junction strategy is proposed to enhance the strong metal‐support interaction (SMSI) between the loaded Ru atoms and the Co3O4 support. The synthesized structure with the incorporation of Ru doping and the (100)/(111) crystal plane junction has a particular influence on the catalyst's hydrogen evolution reaction (HER ...
