Summary: Bimetallic NiMo-supported Al2O3@TiO2 core-shell microspheres were developed for the hydrodeoxygenation (HDO) of syringol. The NiMo@Al2O3 microspheres containing 20 wt% Ni and 10 wt% Mo were prepared by sol-gel and spray pyrolysis, and a TiO2 anatase shell was decorated onto their surfaces. The decorated spheres showed improved hydrocarbon selectivity in the HDO reaction compared to the undecorated spheres. Coating the NiMo@Al2O3 microspheres with a hydrophobic TiO2 shell improved the HDO performance.

Summary: This study presents the synthesis of one-dimensional Au@PtPd@Pt nanowires using a template-induced method, which exhibit exceptional electrocatalytic activity and long-term electrochemical stability for alkaline hydrogen evolution reaction (HER). The nanowires' unique structure, consisting of ultrathin 1D nanowires with a core-shell-satellite structure and trimetallic elemental compositions, contributes to their superior performance. Moreover, the integrated Au@PtPd@Pt//RuO2 electrolyzer achieves a lower operating potential, showing great potential for practical water electrolysis.

Summary: In this study, a bilayer core-shell structure self-assembled V2O3 microspheres (BCSV) was successfully prepared through a combination of hydrothermal process and subsequent heat treatment. The microstructure, defects, dielectric properties, and microwave absorption (MA) properties of BCSV were investigated, and the effect of bilayer core-shell structure on the MA properties was discussed. By adjusting the heat treatment temperature, the thickness of the V2O3 bilayer and its unique structure defects can be regulated, thereby enhancing the attenuation and multiple polarization loss of electromagnetic waves inside the microspheres. BCSV exhibits a high-performance MA property, with a reflection loss (RL) of -67.12 dB at 11.69 GHz and a broad effective absorption bandwidth of 5.49 GHz with a thickness of 2.20 mm after heat treatment at 600 degrees C. The conductivity loss, multiple polarization loss, and dielectric loss are attributed to the specific bilayer core-shell structure. Thus, this work provides a good perspective on how to create vanadium oxide-based MAMs with effective absorption and broad bandwidth.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.
