Summary: In this study, bulk nanocrystalline Cu-Zr-Nb alloys were synthesized and annealed to investigate the reasons for maintaining nanosized grains. The results showed that the grain size remained in the nanoscale range due to solute atoms segregation along grain boundaries and Zenner pinning by intermetallic precipitates.

Summary: The article assesses the solutions and dried residues from the bioleaching process of PCB using Acidithiobacillus ferrooxidans. The analysis of the residues showed a difference in the component oxidation, with the leachate consisting mainly of amorphous particles and the control solution showing crystalline components. The investigation confirmed the activity of A. ferrooxidans bacteria in solubilizing electronic waste components.

Summary: Composites of ultra-thin nanolayers of FeCo/TiN exhibit stability at high temperatures and defined magnetic properties that can be tuned by adjusting layer thickness. Using aberration-corrected microscopes and X-ray diffraction analysis, the nanostructure was found to consist of individual layers of FeCo and TiN forming a superlattice with a specific orientation relationship. Simulation of electron diffraction patterns confirmed a defined orientation relationship leading to the stabilization of tetragonal FeCo unit cells at the nanoscale.

Summary: The TiZrNb metal-matrix composites reinforced by in-situ formed borides were produced using different amounts of TiB2. The composites exhibited varying microstructures and mechanical properties with the increase in boride content. Load transfer strengthening was found to be the main contributor to the overall strength of the composite. The biocompatibility evaluation suggested a decrease in the proliferation rate of mesenchymal stem cells with an increase in boride content.

Summary: In this study, we utilized plastic deformation during end-milling to prepare epsilon-phase Mn-Al particles with micron scale external dimensions and self-similar shapes from binary as-cast feedstock. The structural evolution and magnetic properties were studied after single-pass plastic deformation processing and subsequent thermal annealing. The end-milling process parameters, especially the rotational speed of the cutting tool, were identified to produce self-similar epsilon-phase particles characterized by cold-worked microstructures at sub-micro to nanometer scales. These particles were suitable for the preparation of tau-phase based MnAl particles with enhanced permanent magnet properties through isothermal annealing. The decomposition reactions of the epsilon-phase particles were observed to have higher rates during isothermal annealing, attributed to reduced effective nucleation barriers due to reduced grain size. The end-milling derived Mn54Al46 particles exhibited large saturation magnetization, coercivity, and reasonable squareness ratios, resulting in a maximum energy product of 4.2 MGOe after annealing.

Summary: The glassy phase in (Fe1-xNix)(79)B12P5Si3C1 alloy ribbons exhibits good bending plasticity and Ni-containing glassy alloys show multistage crystallization with different activation energies. The 0.5Ni glassy alloy stands out with the largest SCL region, good soft magnetic properties, and complex crystallization processes. The development of medium-range ordered atomic configurations in the 0.5Ni alloy contributes to its enhanced magnetic softness and lower internal stress state.

Summary: The addition of nitrogen in high temperature alloys leads to the formation of different nitride phases, which can enhance the high temperature and creep properties of the materials. However, there is a scarcity of data for nickel superalloys, making it difficult to accurately predict the formation of various phases.

Summary: This study investigated the decomposition process of the isothermal alpha '' phase in beta-Ti alloys, and found that the resulting alpha + beta dual phase inherited the microstructural characteristics of the alpha ''(iso) phase. The research results indicate the existence of a strict variant selection rule between the decomposed alpha and beta phases, with a specific variant combination observed.

Summary: This paper analyzes the impact of severe plastic deformation on the structure, mechanical and thermal properties, and crystallization process of a Zr62.5Cu22.5Al10Fe5 alloy. High pressure torsion induces atomic changes and the formation of inhomogeneous chemical regions. The alloy structure after mechanical treatment is generally complex, with a residual glassy matrix containing nanocrystalline particles. The observed structural changes during the high pressure torsion process have significant effects on the crystallization process. The effect of shear strain on the crystallization and properties of the Zr62.5Cu22.5Al10Fe5 alloy was studied in detail using TEM, XRD, and DSC methods.

Summary: This study investigated the transdermal fate of ethosomes and transethosomes on human skin. The results showed that the vesicle penetration capability was influenced by their physical-chemical features, with different vesicles reaching different levels of the skin. This offers potential for tailored transdermal drug delivery based on specific cutaneous pathologies.

Summary: This research focuses on the influence of atomic arrangement on the electrical and catalytic properties of oxide thin films. The atomic arrangement of LiNiO2 thin films was investigated by uniaxial compression and annealing at 600℃ on sapphire substrates. Thin films with a rock-salt structure were grown using pulsed laser deposition method at room temperature. It was observed that the as-grown thin films transformed from a rock-salt to a layered structure after uniaxial compression at 600℃, and the layer thickness of the latter structure increased with increasing uniaxial compression pressure. Uniaxial compression provides a useful tool for oxide thin film research, contributing to the development of new functional oxide materials and adjustment of the atomic ordering of cation materials.

Summary: Nanoparticles of CrxAl0.5-xCoFe1.5O4 spinel ferrites were synthesized by co-precipitation technique to study the effects of chromium and aluminum ion substitutions on structure, magnetic properties, permeability, Curie temperature, and AC loss. The results showed that lattice constant and porosity increased with higher Cr3+ concentration, while magnetization, coercivity, and Curie temperature decreased. Additionally, magnetic loss increased with increasing Cr3+ concentration in all samples.
