Summary: In this study, 2D SnO2 nanosheets were synthesized and their sensor characteristics were revealed through various characterization techniques. It was found that due to the high specific-surface-area and increased surface acidity, 2D SnO2 exhibits a high signal towards NH3 in dry air but undergoes sensor response inversion in humid conditions.

Summary: Fe-Co-Ni magnetic nanowire arrays (MNWs) with three-dimensional periodic structures were prepared by DC electrodeposition. XRD results revealed that the Fe-Co-Ni MNWs had a strong preferred orientation in the direction of the bcc FeCo (110) structure. VSM results indicated that the Fe-Co-Ni MNWs had relatively low coercivity, suggesting their soft magnetic properties. Further investigation demonstrated a magnetization reversal mechanism combining curling rotation and coherent rotation. The Fe-Co-Ni MNWs with three-dimensional periodic structures prepared in this study have potential applications in the fields of sensing and spintronics.

Summary: This study investigates the characteristics of Si nanowire (SiNW) heterojunction structure with a two-dimensional SnS2 thin film. The SiNW array, created by the metal-assisted etching method, has a lower reflectivity compared to Si planar substrate. The three-dimensional interface between SiNW and SnS2 thin film improves the diode characteristics. Furthermore, transport mechanisms of the SiNW heterojunction have been examined.

Summary: Recently, metal-dichalcogenides (MDs) have attracted much attention for future optoelectronic devices due to their unique electronic and optical properties. However, the presence of structural defects hinders the application of MDs in device integration by trapping free charge carriers. In this study, ultraviolet (UV) treatment was used to successfully passivate defects in SnS2, resulting in significant improvement in the performance of the photodetector. The UV-treated SnS2 exhibited higher responsivity, external quantum efficiency, and faster response speed compared to the untreated SnS2.

Summary: Core-shell nanowire heterostructure is a new architecture for photodetector applications, which enhances light absorption and improves photodetector performance with enlarged active surface area. SnS2, as a coating material, has gained increasing interest in next-generation optoelectronic materials. In this study, the hydrothermally grown SnS2 and Si nanowire (SiNWs) core-shell heterostructure exhibited enhanced optoelectronic performance. The uniform coating of hydrothermally grown SnS2 on Si nanowire increased the effective junction area of the heterostructure, resulting in improved optoelectronic properties over a broad spectral range (300 - 1100 nm). Specifically, under 340 nm illumination, the core-shell photodetector showed high responsivity (-383 A/W) and extremely high external quantum efficiency (-2 x 105 %) at a low optical power (-20 nW/mm2). This SnS2/SiNWs core-shell heterostructure with significantly enhanced optoelectronic performance holds great potential for high-efficiency photodetector development.

Summary: CoPt nanowires with low Pt content and optimized catalytic properties for methanol oxidation reaction (MOR) were successfully synthesized by electrodeposition. By controlling the synthesis conditions and adding saccharine, the crystalline structure of the nanowires can be changed, leading to improved electrocatalytic performance. The resulting CoPt nanowires exhibit significantly higher catalytic activity than the best reported CoPt nanoparticles, making them promising catalyst candidates for MOR.

Summary: Sulfite determination in foods and alcoholic beverages is achieved using a biofunctionalized Pt-nanoparticle-modified polypyrrole nanowire array (PPyNWA) with the enzyme sulfite oxidase (SOx). The PPyNWA is prepared by dual-step anodisation, followed by deposition of PtNPs and adsorption of SOx. The resulting biosensor shows ultrasensitive detection of sulfite with good analytical performance. The nanobiosensor is also successfully applied to sulfite determination in beer and wine samples with high recovery efficiency.

Summary: In distributed key-value stores, the selection of replica servers is crucial for reducing response time. However, existing replica selection algorithms suffer from poor timeliness of feedback information. To address this issue, this paper proposes an Accelerated Information Dissemination (AID) mechanism that allows both client and replica server to store records about the status of replica servers and piggyback multiple records in the key-value pairs. The results show that AID significantly improves the timeliness of feedback information, especially in large-scale deployments.

Summary: The COVID-19 pandemic in northern Taiwan resulted in the implementation of Level 3 alert measures, significantly impacting air quality and providing an unprecedented opportunity to understand future control strategies for air pollutants. This study comprehensively investigated the variations in sources, chemical characteristics, and human health risks of PM2.5. The study found that PM2.5 mass concentrations and inorganic ions were greatly reduced during the alert period, while organic matter and elemental carbon decreased to a lesser extent, causing a shift in the chemical composition of PM2.5. The study also identified the primary sources of PM2.5 and highlighted the need for continued efforts in reducing carbonaceous matter emissions.
