Summary: Surface grids created using FIB were used to study the grains movement behavior of an Al-Mg-Li alloy with fine equiaxed structure during superplastic deformation. The results showed that grain boundary sliding is the primary deformation mechanism, with a contribution of 34.8% to 51.6%, while intragranular dislocation slip plays an accommodating role.

Summary: This study systematically explores the structural and mechanical anisotropy of 3D-printed high entropy alloys. The results show that the selective laser melting (SLM) process creates an anisotropic structure, which influences the mechanical properties. The 0 degrees sample exhibits the optimal combination of strength and plasticity, while the 45 degrees and 90 degrees samples have reduced ductility.

Summary: Novel alloy systems, such as (FeCoNi)86Al7Ti7 high-entropy alloys, were fabricated using selective electron beam melting. These alloys exhibit ordered L12 and disordered fcc matrix phases. The equiaxed microstructure is observed on the bottom surface, while coarse columnar grains are observed along the building direction. Island-like precipitates and high-density multicomponent cubic nanoparticles are uniformly distributed in the matrix. The (FeCoNi)86Al7Ti7 HEA demonstrates superior strength and ductility, but also exhibits anisotropy in its mechanical properties.

Summary: This study reports the impact of growth rate and substrate temperature on the properties of Fe-Co-Ni alloy thin films. Films with different growth rates (ranging from 1 to 2.4 Å/s) were grown on Si 100 using high power impulse magnetron sputtering. Thermal processing was also performed by altering the substrate temperatures. The films deposited at room temperature exhibited a FCC structure, while those grown at higher substrate temperatures showed the coexistence of BCC and FCC phases. The Fe-Co-Ni films grown at higher growth rate and enhanced substrate temperature exhibited high saturation magnetization and low coercivity. Magnetization and magnetic microstructural studies using Kerr microscopy revealed anisotropic magnetic properties and magnetization reversal dominated by domain wall motion and rotation.

Summary: In 'zero-excess' lithium metal batteries, three-dimensional current collectors with high surface area can effectively reduce local current density and minimize 'dead Li'. This study focuses on the relationship between surface features and electrochemical performance by precisely controlling the surface chemistry of the 3D copper current collectors. Accurate quantification of 'dead Li' is achieved using gas chromatography. The findings contribute to a deeper understanding of the correlation between surface area and 'dead Li' and have potential implications for the application of zero-excess lithium metal batteries.

Summary: In this study, a composite EM wave absorber made of a FeCoNi medium-entropy alloy embedded in a 1D carbon matrix framework is rationally designed. The absorber shows high-density and continuous magnetic network and exhibits excellent magnetic loss ability. The enhanced EM wave absorption performance is mainly attributed to the 1D anisotropy and intrinsic physical features of the magnetic medium-entropy alloy.

Summary: In this study, an Al-Li alloy was prepared by electrodeposition on a solid aluminum electrode in a urea-LiCl molten salt system. The underpotential deposition of Li on the Al electrode was observed, forming Al(a) and AlLi(d) phases, which were confirmed by XRD measurements. The obtained Al-Li alloy deposit had a thickness of 143 μm under the potentiostatic electrolysis at -0.5 V vs. Li+/Li. The Li content in the alloy obtained at 373 K reached 6.9 wt%. Galvanostatic electrolysis at 20 A demonstrated the feasibility of obtaining Al-Li alloy coating on an aluminum plate from the urea-LiCl electrolyte at 373 K.

Summary: In this study, low-cost carbon materials and high-performance sodium- and magnesium-ion batteries were fabricated using hierarchical porous electrodes and superior electrolytes. The use of non-graphitic high-surface porous carbons (NGHSPCs) led to the formation of unprecedented n-stages, resulting in increased initial capacity and improved sodium-ion diffusion. The current approach was also scalable to full sodium- and magnesium-ion cells, achieving high energy densities.

Summary: Microwave calcination is proposed as an alternative route to prepare layered P2-Na2/ 3Ni1/3Mn2/3O2 for sodium-ion batteries. The sample obtained under the fastest conditions of a heating ramp of 20 degrees C min-1 for 2 hours showed well-crystallized rounded particles. It exhibited low internal cell resistance and high diffusion coefficients, allowing for the highest capacity at 1 C and maintaining discharge capacity for at least two hundred cycles.

Summary: Microwave calcination is introduced as a substitute for conventional heating in electric furnace for the production of high-performance electrodes for sodium-ion batteries. The microwave annealing process allows for shorter annealing time and the preparation of pure and highly crystalline Mg-doped Na2/3Ni1/3Mn2/3O2 samples. The electrochemical performance of the microwave calcined samples is superior to a reference sample prepared by conventional heating methods, as evidenced by the kinetic response at different stages of galvanostatic cycling. This improvement can be attributed to the larger crystallite size and lower microstrains achieved through microwave annealing, which result in reduced resistive behavior, higher Na+ diffusion coefficient, and lower internal resistance of the positive electrode.

Summary: The magnesium driven reaction in the olivine-type MgMn0.5Zn0.5SiO4 structure is investigated through experimental tests and density functional theory (DFT) calculations. Partial replacement of Mn in Oh sites by Zn in the MgMn0.5Zn0.5SiO4 cathode is successfully achieved using a simple sol-gel method. Comparison with the well-known MgMnSiO4 olivine-type structure provides insights into the structure and magnesium extraction/insertion properties of the novel olivine-type (Mg)(M1)(Mn0.5Zn0.5)(M2)SiO4 composition. DFT calculations further extend the study to other divalent elements in the olivine-type (Mg)(M1)(Mn0.5M0.5)(M2)SiO4 structure with M = Fe, Ca, Mg, and Ni. The results suggest that the energy density can be tuned between 520 and 440 W h kg(-1) based on the atomic weight and redox chemistry properties, offering new possibilities for cathode material development in Mg batteries.

Summary: After a delay of more than 30 years, sodium analogs are now entering the market as an alternative to lithium-ion batteries. These sodium-ion batteries address concerns about sustainability, production costs, safety, and toxicity. The electrode materials of these batteries can contain sodium, iron, or manganese, eliminating the need for cobalt cathode compounds and copper anode current collectors. Manganese, with its multiple oxidation states and abundance, is favored as a component in these batteries. However, further research is needed to explore the role of manganese in different structural families.
