Summary: By studying the substitution effect of holmium (Ho) element in Ce-Fe-B alloys, it is found that the introduction of Ho can improve the phase constitution and magnetic properties of the alloys. Ho substitution can suppress the formation of CeFe2 phase and tune the magnetic properties of the alloys. The addition of Ho has a significant effect on increasing the intrinsic coercivity, Curie temperature, and thermal stability of Ce-based alloys.

Summary: Controlling thermal energy transfer at the nanoscale and thermal properties is crucial, and this study focuses on the effects on thermal conductivity arising from the nanoscale structure of nanocrystalline silicon films and suspended optomechanical nanobeams. The research uses a micro time-domain thermoreflectance method and introduces a versatile contactless characterization technique for thermal conductivity measurements. In optomechanical nanostructures, the effect of reducing thermal conductivity due to smaller grains is smaller compared to membranes, indicating a competition of surface scattering.

Summary: The formation process of nanocrystalline layer on the rolling contact surface of bainitic steel was investigated. The results reveal that there is a cycle of nanocrystalline layer generation, spalling, and production on the surface. The decrease in the steel surface's elastic modulus indicates the initiation of fatigue damage.

Summary: Platinum diselenide (PtSe2) is a 2D material known for its exceptional electronic and piezoresistive properties, and can be grown at low temperatures in a scalable manner. The nanocrystalline structure of PtSe2 thin films grown using thermally assisted conversion (TAC) was investigated for its correlation with electronic and piezoresistive properties. The findings suggest that variations in crystallite size and orientation have a strong impact on the electronic and piezoresistive properties of the films, offering potential for tuning and optimizing PtSe2 properties for various applications.

Summary: Phase-change materials (PCMs) play a significant role in energy conservation and thermal management systems, but their excessive seepage and insufficient thermal conductivity limit their real-world applications. In this study, anisotropic-like biochar combined with chitosan was designed to encapsulate dodecane, overcoming the high manufacturing costs and environmental issues associated with PCM supporting materials. The resulting composite PCM exhibited outstanding latent heat retention, high thermal conductivity, leakage-free properties, and repeatable utilization above the melting point of dodecane. This study provides important insights for the development of next-generation sustainable energy storage.

Summary: Chalcogenide phase change materials (PCMs) offer great potential for the Optics and Photonics community, providing nonvolatility and large optical property modulation for devices with low-energy consumption and ultra-compact form factors. Precisely controlling the glassy amorphous and crystalline domains of PCMs is a challenging task, but essential for achieving intermediate optical response and repeatable reconfiguration.

Summary: This study investigates the influence of crystallographic texture on the total amount of solute segregated at grain boundaries and weighted grain boundary energy of nanocrystalline materials. The findings show that nanostructures with random texture have higher values of X-gb,X-tot and gamma(w) compared to those with {111} < 110 > texture, which has implications for the development of thermally stable nanocrystalline materials. The effect of texture is further discussed through a case study on the Ni-W system using the nanocrystalline stability criterion proposed by Kalidindi and Schuh.

Summary: Nanocrystalline CuAg foils were fabricated with high strength, electrical conductivity, and moderate ductility. Mild annealing further improved the strength and conductivity of the foils to achieve properties comparable to those of deformed CuAg of greater thicknesses. However, annealing at higher temperatures resulted in decreased strength and increased conductivity of the foils due to grain boundary segregation and precipitation of Ag atoms.
