Summary: TiO2/KNbO3 nanocomposite was prepared by a two-step hydrothermal method, and impedance-type sensors based on TiO2/KNbO3, TiO2, and KNbO3 were fabricated. The TiO2/KNbO3-based sensor exhibited a large impedance change over 5 orders of magnitude, which was 1-2 orders of magnitude larger than that of TiO2- and KNbO3-based sensors. The improved humidity sensing performance of the TiO2/KNbO3 nanocomposite was attributed to the heterojunction at the TiO2/KNbO3 interface and the Grotthuss mechanism. This study highlights the significance of the two-step hydrothermal method in fabricating high-purity nanocomposites with excellent humidity sensing performance.

Summary: Hf1-x(In0.5Nb0.5)(x)O-2 (x = 0, 0.005, 0.05, and 0.1) ceramics doped with (In+Nb) were prepared by a solid-state reaction method. Dielectric measurements showed that environmental moisture significantly influenced the dielectric properties, with the best humidity response observed in the sample with x = 0.005. Nanosized particles of Hf-0.995(In0.5Nb0.5)(0.005)O-2 were fabricated by a hydrothermal method and their humidity sensing properties were studied. The material exhibited a large impedance change of nearly four orders of magnitude over a relative humidity range of 11-94%, which was attributed to the defects created by doping and improved adsorption capacity for water molecules.

Summary: In this study, electrochemical impedance spectroscopy was used to investigate copper oxide (CuO) nanowire networks assembled between metallic microelectrodes by dielectrophoresis. The influence of relative humidity (RH) on the electrical characteristics of the CuO nanowire-based system was evaluated by measuring the impedance Z. The results showed a slight increase in Z with increasing RH at low humidity, followed by a significant decrease in Z at RH above 50-60%. These trends can be attributed to water chemisorption and physisorption at the nanowire interface, which affect electronic transport and enhance ionic transport. The obtained equivalent circuit parameters from fitting impedance spectra were used to discuss the possible physicochemical processes at the nanowire surface. The findings of this study have important implications for predicting the behavior of nanostructured CuO in humid environments and advancing nanowire-based systems for sensor applications.

Summary: The current study investigates the role of reactive oxygen species (ROS) in the bioeffects of different types of magnetite nanoparticles (MNPs) - bare (Fe3O4), humic acids (Fe3O4-Ha), and 3-aminopropyltriethoxysilane (Fe3O4-APTES) modified MNPs. The study found that Fe3O4-HA MNPs had the lowest amount of Fe2+ ions, while Fe3O4-APTES MNPs had the highest amount of Fe2+ ions. Bioluminescent cellular and enzymatic assays were used to monitor the toxicity and antioxidant activity of the MNPs. The results showed that the modified MNPs had toxic effects at higher concentrations (>10(-2) g/L) and stimulated ROS production by bacteria in a wide concentration range (10(-15)-1 g/L).

Summary: A self-powered carbon dioxide (CO2) gas sensor based on CeO2/CdS triboelectric nanogenerator (TENG) was developed, which exhibited good sensitivity and selectivity. The resistive type and self-powered CO2 gas sensing performance of CeO2, CdS, and CeO2/CdS nanomaterials were compared. CeO2/CdS heterostructure was confirmed to form a type II heterojunction through XPS analysis. The CeO2/CdS showed a regular nanosphere morphology with a size range of 30-60 nm. The resistive type CO2 gas sensor achieved a sensor response of 3.96 at 1000 ppm CO2, while the self-powered CO2 gas sensor achieved a response of 30 at the same concentration. The minimum response and recovery times for 250 ppm CO2 were found to be 1835 and 835 ms, respectively. The self-powered CeO2/CdS TENG-based CO2 sensor demonstrated high sensitivity, selectivity, and quick responsiveness.

The value of the conductivity is determined by analyzing the frequency dependence of the complex permittivity in a specific range of frequencies. The temperature dependence of the conductivity shows two distinctive regions: the Vogel-Fulcher-Tammann dependence above the glass transition temperature, and the Arrhenius dependence below it, indicating a change in conduction mechanism after the freezing of ionic mobility.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.
