Summary: This study proposes a method to achieve effective light confinement using non-patterned black phosphorus and patterned silver periodic nanostructures. It is found that the absorption response of the system can be dynamically adjusted by controlling the Fermi level of black phosphorus with voltage. Furthermore, the study explores the in-plane anisotropy of the system by investigating parameters such as the width of silver nanoribbons and the distance between silver and black phosphorus.

Summary: We study the simultaneous narrowband and broadband light absorption enhancement of monolayer graphene on a metallic substrate with a periodic array of small holes. The absorption peaks of graphene are proven to stem from the hybrid modes of delocalized surface plasmon polaritons propagating on the substrate surface and localized magnetic plasmons confined within individual holes. The positions, maxima, and bandwidths of the absorption peaks can be tuned through changing the hole array period. The maximum absorption values at the narrowband and broadband peaks can reach up to 65% and 85%, respectively. The bandwidths of the absorption peaks can be conveniently adjusted, with the narrowband peak reduced to several nanometers and the broadband peak expanded to tens of nanometers.

Summary: The control of surface plasmon using metal micro-nano structures and metal/material composites can generate novel phenomena such as optical nonlinear enhancement, transmission enhancement, orientation effect, high sensitivity to refractive index, negative refraction, and dynamic regulation of low threshold. These phenomena have significant potential in fields such as nano-photonics, super-resolution imaging, energy, sensor detection, and life science. Silver nanoparticles, with their high sensitivity to refractive index change, convenient synthesis, and controllable shape and size, are commonly used in surface plasmon sensors. This review summarizes the basic concept, fabrication, and applications of silver-based surface plasmon sensors.

Summary: A graphitic carbon nitride-wrapped titanate nanotube array (gC(3)N(4)-wrapped TNA) heterojunction photoelectrode was successfully fabricated via a chemical vapor deposition-like process, showing significant enhancement in current density and photo-response under visible light. The enhanced performance can be attributed to the effective charge separation at the gC(3)N(4)/TNA interfaces, leading to accelerated water splitting and oxygen generation. Additionally, the gC(3)N(4)-wrapped TNA photoelectrodes are developed under neutral conditions, making them highly applicable for practical devices.

Summary: Traditional TiO2 semiconductor is a promising photocatalyst, but its application for NO removal under sunlight conditions is gaining attention in materials science. Combining and optimizing TiO2 with carbon materials, such as CNT, have received significant attention for gas pollution treatment. The combination of CNT and commercial TiO2 by ball-milling results in spherical TiO2 particles with an average diameter of 80-100 nm and CNT with a length and diameter of several nanometers and approximately 8-10 nm in the composites. The 0.7%wt CNT in the CNT/TiO2 composite achieves the best photocatalysis for NO removal in a natural environment simulation model.

Summary: Ag and ZnO nanoparticles were synthesized using a green synthesis method from a Pinus latteri tree extraction. The synthesized nanoparticles were characterized using DSC/TGA analyses, XRD patterns, and FE-SEM images. The average particle sizes of the synthesized Ag and ZnO nanoparticles were approximately 25 nm and 45 nm, respectively. XRD patterns confirmed the presence of Ag metal and ZnO wurtzite crystalline phases. Additionally, the agar-well diffusion method showed that both Ag and ZnO nanoparticles exhibited strong inhibitory activity against E. coli bacteria. Specifically, the antibacterial activity of Ag nanoparticles was higher than that of ZnO nanoparticles under the same conditions.

Summary: Cu2O/TiO2 heterojunctions were synthesized by a simple photoreduction method, showing potential photocatalytic activity for environmental treatment. The morphology and size of the materials were examined using high-resolution transmission electron microscopy (HRTEM) imaging. X-ray photoelectron spectroscopy (XPS) analysis revealed the chemical state of copper in the materials. Photoluminescent (PL) spectrum and XPS analyses confirmed the presence of electron trap centers as oxygen vacancies (F center) and oxygen vacancies losing one electron (F+ center). The oxygen vacancies significantly contributed to the visible-light-driven photocatalytic activity of Cu2O/TiO2 heterojunctions.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
