Summary: This study investigated the inhomogeneous dealloying phenomenon during liquid metal dealloying (LMD) using Fe50Ni50+Mg and (FeCo)(50)Ni-50+Mg systems. The results showed that temperature increase enhances the inhomogeneous dealloying kinetics and leads to the formation of abnormal ligaments at the grain boundary region. The energy balance between grain boundary energy and solid-liquid interface energies is a key factor governing the inhomogeneous dealloying. Additionally, the addition of alloying elements can change the grain boundary characteristics and solid-liquid interface energy, thereby significantly affecting the dealloying mechanisms and final morphology.

Summary: A crucibleless liquid metal dealloying (CLMD) procedure was developed to prepare porous materials with improved strength and stiffness. The chemical dissolution of the backbone phase leaves behind a porous-structured matrix, which is the inverse replica of the dealloyed network structure. The ease of the CLMD method and the improved mechanical stability of the obtained porous materials may enable practical applications in various areas.

Summary: Nanoporous metals have shown great potential in various applications, and the liquid Ga-assisted alloying/dealloying strategy is a feasible and scalable method for fabricating substrate-supported nanoporous metals. The study found that the formation of wire-like and bulk-like nanoporous Ag is influenced by the interdiffusion of Ag and Ga atoms, and the thickness of the alloy layer shows a linear relationship with the mass loading of liquid Ga. The mechanical properties of the substrate-supported nanoporous Ag are excellent, which is crucial for future applications of nanoporous metals.

Summary: Porous alloy nanomaterials are important for various applications, and the evolution of individual AuAg alloy NPs during chemical and electrochemical etching processes is tracked using in situ liquid phase transmission electron microscopy. The electrochemical etching method produces NPs with more uniform pore sizes and allows for tuning the NPs porosity by modulating the electrochemical potential. The formation of an Au-rich passivation layer on the surface of NPs at initial stages of etching is critical in preserving the NP's porous shell as pores form underneath this layer during the etching process.

Summary: This study investigates the microstructure and phase decomposition in nanoporous Au-Pt materials fabricated by dealloying. The findings reveal that the enrichment of Pt at the surface and Pt depletion in the bulk during dealloying result in a homogeneous single-phase state in the material. Annealing induces diffusion-driven coarsening and the formation of Pt-rich regions with crystallographic coherence and semi-coherent regions. The study demonstrates the high kinetic stability and tunability of surface composition in nanoporous alloys through annealing.

Summary: Liquid metal dealloying (LMD) has attracted attention for its ability to produce 3D interconnected non-noble metallic materials, and the addition of Ni alloying element to soft Mg phase has resulted in a hierarchical heterostructured composite with high yield strength and noticeable elongation. The complex 3D morphology of ligament and lamellar geometries in the composite prevent the early fracture of brittle Mg-Mg2Ni lamellar phase, offering insights for hierarchical HS materials with outstanding mechanical properties for structural applications.

Summary: Reducing Young's modulus to approximate that of cortical bone is a key goal in the design of load-bearing implant materials. This study explores the use of elastic anisotropy to achieve directionally preferential bulk elastic properties in implant materials, focusing on biocompatible refractory high-entropy alloys (RHEAs). The results show that valence electron count has a dominant influence on elastic anisotropy in RHEAs, and the study discusses the potential for lowering Young's modulus by using single crystals or textured aggregates.

Summary: The hypo-eutectic alloy of Zr45Cu45Al10 was irradiated with 16 MeV and 200 MeV Au ions at room temperature. The effects of irradiation on the structure and hardness of the alloy were investigated using X-ray diffraction (XRD), Extended X-ray absorption fine structure (EXAFS), micro-Vickers hardness, and positron annihilation measurements. Amorphization was confirmed after irradiation, but the change in hardness strongly depended on the irradiation energy. The behavior of hardness showed a decrease and increase trend with increasing fluence for 16 MeV irradiation, while no decreasing trend was observed for 200 MeV irradiation. The EXAFS measurement revealed different changing ratios of Cu-Cu and Cu-Zr bonds around each Cu atom between low energy and high energy Au ion irradiation.

Summary: We propose an improved method for synthesizing borophane sheets. By incorporating hydrochloric acid into the ion-exchange reaction, we significantly increased the production yield from 20% to over 50%. Through a thorough examination, we gained insights into the underlying mechanisms and discovered that hydrochloric acid accelerates borophene production and isolates high-purity products. This method has the potential to enable the production of novel topological 2D materials with potential industrial applications.

Summary: Liquid metal dealloying is a promising technique to produce bicontinuous porous metals with high specific surface areas. However, it has not been applied to produce nickel-containing porous metals because of the lack of a suitable metallic bath. In this study, the authors demonstrate that nickel-containing porous metals can be produced by partial liquid metal dealloying, and the amount of soluble component in the resulting microstructure can be tuned by carefully choosing the bath element.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
