Summary: This study fabricates graphene sheets decorated with Au nanoparticles using milliwatt femtosecond laser reduction, revealing enhanced reduction of graphene oxide sheets and nucleation and growth of Au nanoparticles during the in situ laser treatment. Three stages of reactions are considered, involving spontaneous redox reactions, laser-induced decomposition, and localized surface plasmon resonance enhanced photoreduction. The Au nanoparticles form densely and evenly distributed square-lattice-like microcrack networks, enabling the development of flexible graphene/Au strain sensors with high gauge factors and linear behavior up to 25.4% strain, demonstrating the potential for highly functional, low-cost, flexible, and wearable graphene-based electronics.

Summary: The coupling of piezoelectric and plasmonic effects has been proven to enhance the photocatalytic performances. In this study, a new piezoelectric composite composed of Na0.5Bi0.5TiO3 nanoplates coated with Ag particles was prepared, showing excellent piezo-photocatalytic performances. The plasmonic effect of Ag nanoparticles widened the catalysts' spectral absorption range, and the electric field from the deformation of Na0.5Bi0.5TiO3 piezoelectric nanoplates greatly enhanced the separation and migration efficiencies of photo-generated charge carriers in Ag@ Na0.5Bi0.5TiO3 composites. With simultaneous full-spectrum lights and ultrasonic excitation, the piezo-photocatalytic activity of Ag@ Na0.5Bi0.5TiO3 achieved a significant degradation rate of 98.8% RhB in just 30 minutes.

Summary: The plasmonic Ag@AgBr nanoparticles were successfully synthesized on a TiO2 nanorod array through a secondary hydrothermal method. The crystallization time of Ag@AgBr was found to significantly affect the crystallinity, size, and optical properties of the ternary arrays. With an increase in crystallization time, the crystalline behavior of Ag@AgBr improved, leading to larger nanoparticles and a redshift in the surface plasmon resonance bands. The Ag@AgBr/TNR arrays exhibited enhanced photocatalytic efficiency in the degradation of methyl orange due to the synergistic effect of improved solar light response and efficient charge transfer.

Summary: Heavy metal germanate glasses with silver and erbium were prepared using the melt-quenching method. Controlled thermal treatment led to the formation of Ag nanoparticles, which were monitored using in-situ UV-Vis spectroscopy. TEM images showed that Ag nucleation began after 60 minutes and reached an average size of 4.3 nm after 210 minutes. The luminescent properties were influenced by the size of the Ag nanoparticles, as observed through nanoclusters Ag emission and upconversion of Er3+. Overall, the results highlight the importance of controlling the size of Ag nanoparticles for tunable emission in these glasses, suggesting their potential for optical applications.

Summary: Bi2Se3 nanoplatelets were synthesized with Ag deposition on Al2O3(100) substrates, resulting in enhanced photocurrent and photosensitivity under UV and visible light. This enhancement is attributed to narrow bandgap of Bi2Se3, Schottky field at Ag-Bi2Se3 interface, surface plasmon resonance from Ag, and highly conductive surface from Ag-Bi2Se3.

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: 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.
