Summary: The serious mismatch between bacterial infections and antibiotic production calls for the emergence of new antimicrobial materials. In this study, dopamine methacrylamide and N-isopropylacrylamide were polymerized to form a block copolymer, which was then encapsulated with polydopamine-coated magnetic nanoparticle clusters to create an antibacterial nanocomposite. The nanocomposite exhibited triple responses to light, heat, and magnetism, allowing it to effectively kill bacteria and capture/release bacteria. The results showed that the antibacterial effect of the nanocomposite was significantly higher than that of the magnetic nanoparticle clusters, and it also possessed excellent antibiofilm properties.

Summary: Family of MXenes, the 2D transition metal carbides, nitrides, and carbonitrides, has gained significant attention due to their tunable optical, electronic, electrochemical, and mechanical properties, leading to the emergence of compact nonlinear optical (NLO) devices. MXenes, as a novel 2D materials system, not only possess the advantages of classical 2D materials for NLO applications, but also demonstrate unique superiority such as high yield and scalable synthesis, stability, and switchable NLO response. This article provides a comprehensive overview of MXenes nonlinear optics, covering synthesis, linear and NLO properties, NLO applications, as well as challenges and future prospects of MXenes NLO research.

Summary: This study reports a clear experimental observation of in-plane CPGE in 1T'-MoTe2, which is found to be related to an in-plane internal DC electric field. The circular photogalvanic response is attributed to a third-order nonlinear optical effect involving this DC electric field, consistent with the crystal symmetry of the lattices in both the 1T' and T-d phases of the material.

Summary: Antimony sulfide/reduced graphene oxide (Sb2S3/RGO) nanocomposites were synthesized, and their tunable nonlinear optical properties were investigated. The results showed that the addition of graphene changed the absorption properties of the composites, and the third-order nonlinear susceptibilities were also tunable with the concentration of graphene. These tunable properties make the Sb2S3/RGO composites applicable to photonic devices.

Summary: Due to solubility issues, porphyrin-POM hybrid materials with excellent NLO properties are replaced by polymeric materials. This study evaluates the third order NLO and second hyperpolarizability of porphyrin-polyimide compounds. The results reveal the significant role of Zn ion in charge transfer process and the inverse effect due to ruffled deformation in the normal coordination structure of metalloporphyrin.

Summary: The study used modeling and simulation to demonstrate that liquid crystal surface plasmon resonance biosensors have different responses to temperature changes, and can detect variations in biological agents through shifts in surface plasmon resonance angles. The sensitivity increasing rate in homeotropic alignment was found to be higher than in homogeneous alignment, and sensors based on 5CB and 5PCH had greater sensitivity compared to E7 and E44 liquid crystals.

Summary: Three samples of 99.97% pure rolled tungsten were annealed at different temperatures, and the effects of annealing on defects and their structure were investigated. The results showed that increasing the annealing temperature can significantly decrease the density and size of defects and change their structure. Defect removal from tungsten begins at a temperature of 1400 degrees C.
