Summary: In this study, the effect of bending detection on the surface-enhanced Raman spectroscopy (SERS) effect of a flexible substrate was examined. The results confirmed that bending did not affect the SERS effect. A flexible AgNTs@Cu mesh substrate was successfully fabricated and demonstrated excellent sensitivity for detecting low concentrations of dyes and in-situ detection capabilities for solids and liquids with uneven surfaces. This work has the potential to provide a universally applicable SERS substrate.

Summary: The instability of hot spots is a key limiting factor for the poor spectral reproducibility of SERS. Hot spots exhibit stability thresholds to excitation power, duration, and wavelength. Lowering the excitation power below the threshold or deliberately removing unstable hot spots can significantly improve the stability and reproducibility of SERS signals.

Summary: Ag@C core-shell nanoparticles were prepared by a low-temperature heating-stirring method and subsequently modified with polyethyleneimine (PEI). Ag@C@Ag hybrid nanoparticles were then fabricated with 24-nm Ag NPs attached, demonstrating excellent optical properties for surface-enhanced Raman scattering (SERS) applications. Finite-difference time-domain simulations indicated that the signal enhancement was attributed to the Ag NPs, hot spots, and external assembly, allowing for ultrasensitive spectral analysis.

Summary: In this study, a conventional silicon wafer was treated to expose terraces within the silicon nanostructures (Si-NSs) and decorated with silver nanoparticles (Ag-NPs) to enhance the surface-enhanced Raman scattering (SERS) activity. The SERS activity of Ag-NPs-decorated Si-NSs was found to be significantly enhanced compared to pristine Si-NSs. Three electromagnetic field models were developed to support experimental observations, indicating that Si-NSs facilitate light confinement and can be cascaded within different Ag-NPs-decorated terraces.

Summary: In this study, a simple photolithographic method was demonstrated to generate highly sensitive SERS hot spot structures at desired positions. The solid-state dewetting of an Ag thin film using a continuous-wave laser resulted in the formation of closely packed assemblies of hemispherical Ag nanoislands with substantial plasmonic-field enhancement. These hot spot structures can be utilized as position-specific chemical-sensing elements in integrated analytical devices.

Summary: A novel composite substrate of graphitic carbon nitride/molybdenum disulfide/silver with a 3D surface structure was successfully developed for the recyclable detection of gefitinib in serum. The uniform and dense hotspots on the shrubby active surfaces, along with the potential synergistic chemical enhancement of g-C3N4/MoS2 heterosystem, demonstrated a remarkable SERS sensitivity. The type-II heterojunction between g-C3N4 and MoS2, assisted by the localized surface plasmon resonance of Ag NPs, enabled more efficient diffusion of photogenerated e--h+ pairs and contributed to the reliable recyclable detection of gefitinib with ultra-low detection limit and high recycling rates.

Summary: In this study, a design strategy using glutamic additive and its derivatives was proposed to improve the electrochemical stability and interfacial reactions of aqueous zinc batteries. The additives preferentially absorbed on the zinc surface, homogenized zinc plating, and weakened the interaction between water and zinc ions, leading to uniform deposition and stable electrochemical performance. The results showed improved Coulombic efficiency and capacity of the zinc batteries.

Summary: In this study, Fe(III) ions were incorporated into TiO2 hollow submicrospheres, which served as an excellent photocatalyst. The experimental parameters such as flow rate, rotation speed, and contaminant concentration were found to improve the catalyst activity. Fe-TiO2 hollow submicrospheres with different Fe wt% were prepared, and it was discovered that 2.5 wt% Fe-TiO2 exhibited the best photocatalyst activity. The Fe(III) doping not only increased the interaction between transition metal (Fe and Ti) 3d orbitals in TiO2, but also promoted the Fe(III)/Fe(II) redox kinetics and the associated photo-Fenton degradation of acetaminophen.

Summary: Anode-free lithium metal batteries (AFLMBs) are considered as potential high-energy devices in the future. To overcome the challenges of interface reactions and internal short circuits, a solvent-free approach is proposed to fabricate deformable sulfide composite solid electrolyte (SCSE-4) by incorporating lithium argyrodite (LPSC) and other materials. The SCSE-4 electrolyte exhibits high Li-dendrite inhibition capability and delivers ultra-stable cycling with high coulombic efficiency.

Summary: Carbon@titania yolk-shell nanostructures are successfully synthesized and used as a photocatalyst to degrade acetaminophen. The presence of residual carbon nanospheres is found to improve the photocatalytic efficiency. X-ray absorption spectroscopy analysis reveals the structural and electronic changes in the hollow shell. In situ XAS measurements show that the existence of amorphous carbon nanospheres inhibits the recombination of electron-hole pairs, leading to enhanced photodegradation of acetaminophen. Charge transfer from TiO2 to carbon nanospheres reduces electron-hole recombination and increases photocatalytic efficiency.

Summary: The design of therapeutic nanoplatforms based on fluorescent carbon dots (CDs) has become a viable strategy due to their aqueous solubility, biocompatibility, and ease of functionalization. Through doping heteroatoms into CDs structures, N-, Cl-, and S-doped CDs (NClS/CDs) and Se-, N-, and Cl-doped CDs (NClSe/CDs) were synthesized with superior optoelectronic properties. These doped CDs showed enhanced quantum efficiencies and were used for photodynamic therapy (PDT) by efficiently producing reactive oxygen species (ROS) under laser irradiation. Nanovesicles (NVs) loaded with camptothecin (CPT) drug were designed using NClS/CDs, which exhibited ROS-triggered drug release. The study presented an image-guided PDT and chemotherapeutic platform based on the NVs, showing potential for future cancer treatment.
