Summary: Nanostructured composite oxides, such as nest-like MnO2/TiO2, show superior sensing performance for triethylamine, highlighting the importance of composition and nanostructure modulation in gas sensors. The presence of heterojunctions and homojunctions between different oxide components further enhance the sensor response towards toxic volatile organic compounds.

Summary: Nanostructure modulation is effective for high performance TiO2-based gas sensors. By using a wet-chemistry route to precipitate directly branched TiO2 nanowire arrays on alumina tubes, the sensors exhibit enhanced response due to the unique porous architecture and quasi-aligned nanostructure. The phase junctions between the backbone and branch of the branched TiO2 nanowire arrays help resistance modulation, leading to excellent sensor properties.

Summary: In this work, MoS2 core-shell nanoparticles were prepared by liquid-phase processing of bulk MoS2 using a femtosecond laser. The core of the nanoparticles had incomplete and weak crystallinity, while the shell had high crystallinity. The formation mechanism involved laser ablation and light exfoliation. The core-shell nanoparticles exhibited high chemical activity for chemical catalysis.

Summary: A general photoelectrical deposition process is described for preferentially depositing noble metals inside surface mesopores formed in the interstitial regions between crystal arrays. The coherent crystalline structure allows for smooth electron flow and noble metal deposition in the recesses of surface mesopores, with the size and morphology of the deposited noble metals easily controlled. This approach is applicable to a wide range of functional materials and has potential for preparing excellent photocatalysts, redox catalysts, and photochromic materials.

Summary: The preparation method can greatly affect the properties of mixed-oxide materials, which often show better performance in photocatalysis and gas sensing compared to single-metal oxides. In this study, semiconductor nanomaterial hybrids based on TiO2 and ZnO were prepared using laser ablation and tested as chemiresistive gas sensors. The gas-sensing properties of the hybrids were found to be influenced by their surface chemistry, morphology, crystallinity, and phase composition.

Summary: The study aims to predict the galactic cosmic-ray flux for the Solar Orbiter mission in order to evaluate the performance of the Metis coronagraph. By comparing observations with Monte Carlo simulations, it was found that cosmic rays only interact with a fraction of the pixel sample and the overall efficiency for cosmic-ray identification is linked to certain GCR particles. This analysis will continue throughout the Solar Orbiter mission for diagnostic purposes and potential long-term monitoring of the GCR proton flux.

Summary: This letter discusses the first Solar Orbiter (SO)-Parker Solar Probe (PSP) quadrature on January 18, 2021 to investigate the evolution of solar wind from the extended corona to the inner heliosphere. By tracking the same plasma volume observed in the corona with Metis coronagraph on Solar Orbiter to PSP, it allows for the linking of local properties of the solar wind to its coronal source region. The close approach of PSP to the Sun and simultaneous Metis observation of the solar corona provide unprecedented accuracy in inferring the flow-aligned magnetic field and bulk kinetic energy flux density along the coronal current sheet.

Summary: In this study, we investigate the properties of coronal loop foot-point heating with high resolution observations. We find that the number density near the foot-points in the active region is higher than in the quiet Sun region. Numerical simulations show that a certain number of spicules are required to reproduce the synthetic AIA 171 angstrom signatures.

Summary: This study combines data acquired by remote-sensing instruments on board Solar Orbiter to investigate the eruptions and different source regions. By using different 3D reconstruction methods, the expansion process of the eruptions from their source region to the intermediate corona is traced. The analysis of Metis data provides new insights into solar eruptions, including the formation of a post-CME current sheet and the measurement of plasma temperature gradient. The application of the polarization ratio technique improves the accuracy of the data and constrains the 3D plasma distribution.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study investigates the wettability of the Ti-Cu-Fe multi-metal system, specifically the wetting behaviors of CuSi3 droplets on TC4 and 304SS plates. The results show that the CO2 + Ar gas atmosphere significantly affects interfacial mass transfer, thus influencing the wettability of the systems.

Summary: This study developed Co/MXene composites with anti-corrosion properties by varying the cobalt content. These composites exhibited remarkable electromagnetic absorption performance and high resistance to corrosion under various corrosive conditions. The study also revealed the mechanism of electron transfer from cobalt to MXene and the electromagnetic dissipation behavior originated from polarization loss alone.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.

Summary: In this study, FeOx@SPNO-C core-shell nanospheres as a catalyst for degradation of sulfamethoxazole (SMX) were successfully synthesized. The synergistic interaction between FeOx and SPNO-C, high carbon charge density, and the presence of C = O groups and N/Fe-Nx sites were found to be key factors for the enhanced degradation of SMX.
