Summary: Zn-Sb alloy films were successfully prepared by electron beam evaporation through ion beam assisted deposition, with controlled structure and chemical composition. The experiment demonstrated that the carrier concentration of the film can be effectively regulated by adjusting the ion beam current, leading to enhanced thermoelectric properties within the optimal carrier concentration range for Zn-Sb based materials. The IBAD technique shows great promise in fabricating Zn-Sb films with excellent thermoelectric performance and potential for producing other thermoelectric materials.

Summary: This study investigated the glass-forming range, microstructural features, and soft magnetic properties of (Fe(1-x-)yCo(x)Ni(y))(86)B-14 alloys. It was found that Fe-rich compositions have the largest glass-forming range and exhibit nano-scale grains with bcc and fcc structures after ultra-rapid annealing. The coercivity and saturation magnetic polarization of the nanocrystalline alloys are affected by Co and Ni content, with Co addition generally increasing coercivity and saturation magnetic polarization, while Ni addition has the opposite effect.

Summary: The co-implantation of Sr and Ag ions induces amorphisation and subsequent recovery of the glassy carbon structure, resulting in a graphite-like structure after annealing. Instrumented indentation experiments show enhanced mechanical performance of the irradiated glassy carbon substrates, with only partial reversibility after annealing. The conductivity of glassy carbon is reduced after Sr and Ag co-implantation, but increased after annealing.

Summary: 3D nanostructures are crucial for creating custom devices with unique functionalities. This study presents a method using ion beams to induce bending and folding in membranes, resulting in the formation of nano-kirigamis with controlled angles and directions. The approach involves milling 2D patterns into the membrane using helium or neon ion beams, followed by broad and uniform irradiation using gallium ion beams to induce out-of-plane bending. This technique allows for the fabrication of complex 3D nanostructures and branched nanowires.

Summary: In this work, two previously incompatible techniques are combined to define electronic devices. By using focused ion beam (FIB) to shape three-dimensional crystals and two-dimensional electrostatic accumulation of charge carriers, a sacrificial protective layer is used to preserve the surface quality. The accumulation of charge carriers using ionic liquid gating demonstrates the superconductivity of the accumulated carriers, and this technique opens new possibilities for electrostatic charge tuning in materials.

Summary: Three annealing treatments were designed to regulate the morphology and distribution of alpha phase in Ti-55511 alloy weld. Double annealing showed the highest enhancement in joint strength, with an increase in yield and tensile strengths. The improvement was mainly attributed to the alternate distribution of newly formed lamellar alpha and acicular secondary alpha phase achieved through the transformation and growth of punctated martensite phase and the precipitation of acicular secondary alpha phase. This study provides a novel annealing treatment to improve the strength of titanium alloy EBW joints.

Summary: In this study, Sb/Fe2S3 nanocomposites were fabricated and used as anode materials for sodium-ion batteries. The Sb/Fe2S3-15% composite exhibited high reversible capacities at different current rates, outperforming most Sb-based anodes. The reversible behavior of Fe2S3 and Sb phases during charge/discharge cycling was demonstrated, and the presence of exfoliated graphite facilitated Na+ diffusion and e(-) conduction.

Summary: Co0.5Ni0.5CrxFe2 - xO4 nanoparticles with various chromium concentrations (0.0 <= x <= 1.0) were synthesized using the hydrothermal method. The structural, characteristic, dielectric, and magnetic features of the nanoparticles were analyzed using XRD, FT-IR, SEM-EDS, TEM-SAED, and VSM measurements. The results showed that the nanoparticles had a hexagonal crystal structure and their morphology changed from spherical to oval-shaped with increasing chromium content. The nanoparticles exhibited spinel structure formation and soft ferromagnetic property. The electromagnetic constitutive parameters and microwave absorption properties were determined based on S-parameters and return losses. The microwave absorption occurred in the frequency range of approximately 11 GHz to 12.4 GHz in the X-band and extended towards the Ku-band.

Summary: The rapid development of portable electronic gadgets has encouraged the research of energy-storage systems in the last decade. Hybrid-ion capacitors, which combine the features of capacitors and batteries, have gained significant interest due to their high power density, energy density, and long lifespan. While lithium-based energy storage technology is widely studied for electric grid storage, the unstable commercialization caused by price increments and intermittent availability of lithium reserves has led to the exploration of sodium-based technologies as potential substitutes. Sodium-ion capacitors, with lower costs and standard electrode potentials compared to lithium-ion capacitors, are regarded as innovative energy storage technologies. However, the large size of sodium ions poses challenges in terms of reaction kinetics, energy density, and lifespan. Transition metal oxide-based candidates have emerged as promising options for sodium-ion capacitors due to their large theoretical capacity, environmental friendliness, and low cost. This study provides a summary of the current advancements in research on transition metal oxides and sodium-based transition metal oxides as electrode candidates for sodium-ion capacitor applications, as well as an examination of the state of exploration and future prospects of transition metal oxides for sodium-ion capacitors.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
