Summary: An experimental analysis was conducted to optimize the structure of Ni-Ni(OH)(2)/NiO core-shell nanowire electrodes for pseudocapacitor applications. The thickness and composition of the active phase shell were found to be affected by thermal treatments at different temperatures, resulting in varying capacitance values. Tailoring the capacitance of the electrodes by controlling the nanowire length was evaluated, showing that mass transfer resistance can be negligible within a certain range.

Summary: An anodic aluminum oxide (AAO) template is used to prepare highly ordered Co nanowire arrays with smooth and uniform surfaces. The Co nanowires exhibit high coercivity due to their strong shape anisotropy and magnetic dipolar interactions. Heat treatment results in the formation of a Co3O4 (shell)-Co (core) structure, which further increases the coercivity and remanence ratio of the nanowires.

Summary: Nanomaterials, especially magnetic nanowires, have garnered attention across various fields for their ability to identify objects based on their magnetic signatures. Ferromagnetic resonance (FMR) is the fastest measurement method and shows potential to identify multiple high-frequency signatures simultaneously. Iron, cobalt, and nickel MNW samples were fabricated and measured using an FMR-identification (FMR-ID) system, which was optimized for DC bias fields parallel to the nanowires and microwave frequencies of 20 GHz or higher. This MNW-based FMR-ID labeling system is effective for applications requiring small identification markers.

Summary: In this paper, a Cr(OH)(3) NSs@ZIF67 (NSs = nanosheets) electrocatalyst is prepared on foam Ni via a simple and rapid electrochemical deposition method. Excellent electrocatalytic activity of Cr(OH)(3) NSs@ZIF67 is demonstrated. It can use the overpotential of 281 mV and 390 mV respectively to drive 10 mA cm(-2) and 50 mA cm(-2). The Cr(OH)(3) NSs@ZIF67 electrode shows the highest initial current density compared with the other two monomer electrodes and exhibits excellent stability. It has the largest electrochemical activity specific surface and lowest charge-transfer resistance, promoting the development of low-cost non-noble metal composites in energy chemistry.

Summary: Fe-based nanowires containing nonmagnetic elements, fabricated using a pulse electrodeposition method in porous anodic alumina membranes, exhibit magnetic tunability. The magnetic properties of Fe100-xSnx NW arrays, with a diameter of about 35 nm, such as coercivity and squareness values, decrease with increasing Sn content. The structure of the FeSn NWs, dominated by Fe or FeSn alloy crystal phase, can be either single domain or pseudo-single domain states depending on the Sn content.

Summary: FeCr-based nanowire arrays were fabricated using pulsed ac electrodeposition technique, with varying Cr electrolyte concentrations impacting their morphological, compositional, structural, and magnetic properties. The addition of Cr enhanced coercivity and squareness of Fe NWs, while alloying with Cr kept properties almost constant but affected the NW length compared to pure Fe NWs. Increases in Cr concentration led to reduced magnetostatic interactions and potentially higher local interactions within the FeCr NW arrays.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
