Summary: This work demonstrates the enhancement in plasmonic sensing efficacy by spatially-localized functionalization on nanostructured surfaces, where probe molecules are concentrated in areas of high field concentration. SERS measurements on nanostructured surfaces with homogeneous and spatially-localized functionalization with thiophenol show that the Raman signal mainly originates from high field concentration areas. TERS measurements with 10 nm spatial resolution confirm the predicted field distribution profiles.

Summary: Glass-ceramics in the xBeO-20Fe2O3-(80-x)TeO2 system with x = 0-25 mol% were synthesized and studied. The addition of BeO supported the crystallization of Fe2O3 during melting, resulting in an increase in the crystalline Fe2O3 phase and crystallite size with higher BeO content. Samples doped with BeO exhibited enhanced polymerization of the residual tellurite glass network compared to undoped samples, and all synthesized materials showed spin-glass behavior. Additionally, the Morin transition of hematite at 260 K was observed, with the intensity depending on Fe2O3 content and correlating with the amount of added BeO.

Summary: A temperature dependent Raman spectromicroscopic study was conducted on multiwall carbon nanotubes to investigate anharmonic effects, revealing non-linear shifts in the peak position of Raman D- and G-bands with temperature. Phonon softening and hardening of Raman modes were observed over a wide temperature range, with the G-peak shift explained by anharmonic properties of the graphite lattice. The width variation of the G-peak appeared to be nearly independent of temperature due to competing effects from electron-phonon coupling and anharmonic contributions.

Summary: Efficient heterojunction photocatalysts with spatial separation of photogenerated carriers are crucial to photo-catalysis. The unique carbonized polymer dots/ZnIn2S4 (CPDs/ZIS) Z-scheme heterojunction is designed to realize efficient spatial directional separation of photogenerated carriers and deliver enhanced photocatalytic performance in pollutant degradation. The CPDs generate more superoxide radicals to facilitate mineralization of organic pollutants and retain more holes for oxidation, while the Z-scheme migration mechanism of photogenerated carriers in the CPDs/ZIS composite preserves the original valence band potential of ZIS.

Summary: Micro-arc oxidation (MAO) was used to treat Ti-6Al-4V electron-beam-welded joints, and the effects on microstructure, phase composition, and corrosion resistance of the joint and surface coating were studied. The MAO treatment resulted in a phase transformation in the joint and a denser and thicker coating. The XRD analysis confirmed the presence of rutile and anatase phases in the coating. The corrosion tests showed a significant decrease in corrosion current density and an improvement in corrosion resistance due to the MAO treatment. Long-term exposure to a high-stress corrosion environment also revealed the formation of a protective layer on the joint.

Summary: The construction of heterostructures using atomic layer deposition and high-energy metal plasma implantation has a significant impact on the catalytic activity of cobalt oxide in the oxygen evolution reaction (OER). Among different metals, the heterostructure constructed with cobalt oxide and zirconium metal exhibits better OER activity than silver, titanium, and chromium metals. Increasing the number of zirconium atoms and the thickness of the cobalt oxide layer initially enhances the OER activity and then gradually decreases it. The Zr500/12CoO metal-semiconductor heterojunction has a higher barrier height and more electron-hole pairs, leading to a more positively charged metal surface and promoting the adsorption of OH-. The construction of metal-semiconductor heterojunctions provides insights into the design and surface-interface modification of efficient, low-cost, and durable electrodes for water splitting applications.

Summary: A novel terahertz anti-resonant fiber is designed with high-resistivity silicon in the fiber and nested double-layer U-shape tubes, which effectively reduce the transmission loss. The fiber's confinement loss and effective material loss are analyzed and optimized using the finite element method. The optimized fiber demonstrates a low total loss of 3.1 x 10-3 dB/m at 1 THz and a low-loss transmission bandwidth of 0.44 THz in the range of 0.5-1.5 THz. Bending analysis shows that the bending loss is less than 2.1 x 10-2 dB/m at 1 THz for bending radii bigger than 60 cm. This anti-resonant fiber exhibits excellent performance and holds high commercial potential in terahertz waveguides.
