Summary: In this study, an extensive molecular dynamics investigation was conducted on the thermomechanical properties of cylindrical Fe, Ni, and Fe/Ni core/shell nanowires under uniaxial tensile strain. The nanowires were found to be elastically softer than bulk iron, with a weakening effect observed as sample diameter increased. Additionally, shape memory effect was observed in Fe/Ni core/shell systems grown along specific crystal directions, making them potentially attractive for technical applications.

Summary: By modulating pyrolysis temperature, catalysts with different carbon shells (amorphous carbon, graphene or graphite shells) coated theta-Fe3C and/or alpha-Fe nanoparticles are acquired. It is found that O-Fe3C is confirmed to be FTS active with superior CAC chain growth ability, showing higher C5+ selectivity and lower CH4 selectivity. Meanwhile, graphene shell inhibits iron nanoparticles aggregation and stabilizes the catalysts.

Summary: Chemotherapy is a common anticancer treatment but its disadvantages include toxic effects on both cancer cells and healthy tissues. Encapsulation and targeting drugs is a solution to this problem. This study developed multifunctional 5-FU nanocarriers using a layer-by-layer method, with biocompatibility and drug activity confirmed through MTT tests. Real-time observation of these nanocarriers and drug accumulation in the target was successfully demonstrated using fluorine magnetic resonance imaging (F-19-MRI).

Summary: Soft magnetic composite (SMC) cores were obtained by Spark Plasma Sintering (SPS) using pseudo core-shell powders, consisting of a core of soft magnetic particle surrounded by a thin layer of nanosized soft ferrite. Different compositions of pseudo core-shell powders were prepared, and the compacts were characterized using various techniques. The electrical resistivity of the SMC cores is significantly higher than that of supermalloy, and the magnetic properties are affected by the sintering temperature and time. The initial relative permeability and power losses of the SMC cores are stable up to a certain frequency.

Summary: Ni/Ni3C core-shell nanoparticles with an average diameter of approximately 120 nm were synthesized via a chemical solution method. It was observed that a thin Ni3C shell measuring approximately 1-4 nm formed on the surface of the nanoparticles over time, and the Ni core consisted of multiple grains. The saturation magnetization of the core-shell nanopowders decreased in proportion to the amount of Ni3C. The synthesis mechanism of the Ni/Ni3C core-shell nanoparticles was proposed based on XRD, XPS, and TEM analyses.

Summary: Double perovskites have been investigated as catalyst electrode materials for electrochemical water splitting. Metal-doped double perovskites were prepared and studied for oxygen evolution reaction (OER) in an alkaline medium. The results showed that a specific catalyst configuration exhibited excellent OER properties with low overpotential, low Tafel slope, and long cycling stability. A-site doping altered the electronic properties and surface structure of the catalyst, which enhanced its performance.

Summary: This study investigates the formation and interaction of charge-ordered clusters and the change of orbital order in cold-pressed Fe3O4 through comprehensive magnetoimpedance analysis. The findings reveal the significant impact of physical and magnetic inhomogeneities on the impedance response, as well as the shielding and deshielding of charge-ordered clusters. The study demonstrates the complex interplay between charge ordering and magnetic ordering in Fe3O4 nanoparticles and provides insights into the electrical properties of these materials.
