Summary: A multifunctional dressing based on bacterial cellulose (BC) deposited with a tannic acid/Cu2 + ion/Mg2 + ion (TCM) complex film is developed in this study. The TCM complex exhibits robust interfacial adhesion and good photothermal properties to effectively eradicate bacteria in the wound area under near-infrared (NIR) irradiation. The released Cu2 + and Mg2 + ions from the TCM complex are favorable for endothelial cell proliferation, migration, and tube formation in vitro, promoting angiogenesis and collagen deposition in bacteria-infected wounds.

Summary: Mercury (Hg) in seawater poses a risk to organs and the nervous system when consumed through the food chain. Therefore, there is a need for a rapid and convenient sensor to detect and monitor Hg(II) in seawater. A ZnO-CNTs/Nano-Au modified glassy carbon electrode was prepared and found to have a larger specific surface area, increased ion adsorption, and enhanced conductivity. Differential pulse voltammetry (DPV) was used to determine trace amounts of Hg(II) in seawater, with optimized conditions of accumulation potential, accumulation time, pH value, film thickness, and concentration. The proposed method showed a linear relationship between oxidation peak current and concentration, with a detection limit of 0.0118 μM and recovery values of 94.2% to 98.4% in coastal water analysis. The ZnO-CNTs/Nano-Au-modified electrode demonstrates high sensitivity, convenient operation, and practical applicability.

Summary: This research introduces a seawater desalination system powered by photovoltaic and solar thermal energy, designed for remote regions lacking access to fresh water. The system's performance is demonstrated through experiments, focusing on factors such as photovoltaic power output, power quantity, and water yield under varying solar conditions. A PLC controller is used to adjust the water pump based on sensor data, and a load switching time system is implemented to optimize energy usage in different environments. An improved Perturbation and Observation algorithm is proposed as a new Maximum Point Power Tracking method to enhance the system's efficiency. Simulation tests show that the improved algorithm performs better in tracking the maximum power point and reduces oscillation. Hardware experiments confirm the stability and flexibility of the system, with a daily energy production of 5.18 kWh and freshwater yield of 335.81 kg. The unit's maximum yield can reach 565.75 kg per day and the maximum daily power generation is 8.12 kWh.

Summary: To protect human health and life, it is necessary to detect cadmium ions in seawater with high sensitivity. A Nano-Fe3O4/MoS2/Nafion modified glassy carbon electrode was prepared using a drop coating method. The electrocatalytic properties of the modified electrode were measured using Cyclic Voltammetry (CV). Differential Pulse Voltammetry (DPV) was used to study the stripping Voltammetry response of the modified electrode to Cd2+. Under the optimal conditions, a linear relationship between Cd2+ concentration and detection limit of 0.053 mu g/L was achieved in the range of 5-300 mu g/L, with a recovery rate ranging from 99.2 to 102.9% in seawater.

Summary: The subgrade filling materials have an impact on the settlement of expressway widening projects with a soft soil foundation. Through on-site monitoring and finite element simulation, the settlement and lateral displacement of a lime soil subgrade and a mixed gravel and lime soil subgrade are analyzed and compared. The results show that although the settlement trends are similar for both subgrade types, the mixed gravel and lime soil subgrade has larger settlement and lateral displacement values compared to the lime soil subgrade. Additionally, the differences in foundation surface settlement, lateral displacement, and subgrade layered settlement between the two subgrade types vary with distance, depth, and time.

Summary: In this study, an immunosensor was constructed using a multi-wall carbon nanotube-chitosan oligosaccharide nanocomposite membrane loaded with phenanthrene antibody. The immune reaction, coupled with strong electron transfer ability of multi-walled carbon nanotubes and film formation ability of chitosan oligosaccharides, was used to amplify the detection signal. The sensor showed a high sensitivity for phenanthrene detection in seawater, with a detection limit of 0.30 ng·mL(-1) and a wide detection range (0.5-80 ng·mL(-1)). It provided a stable, sensitive, and accurate method for real-time monitoring of marine environments.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
