Summary: The study demonstrates the potential of separation membranes with switchable wettability in efficiently treating both oil-in-water and water-in-oil emulsions. By using a simple co-deposition method of tannic acid and diethylenetriamine, commercial polypropylene membranes are endowed with switchable surface wettability that can cyclically translate between hydrophilicity and hydrophobicity through water/ethanol treatments without losing surface wettability. Density functional theory simulations and UV-vis spectra analysis were used to illustrate the chemical mechanism behind this hydrophilicity-hydrophobicity translation.

Summary: The development of functional membranes with easy operation, low cost, high stability, and large flux is urgently required for effective treatment of increasing oily wastewater. In this work, NaA zeolite/copper mesh composite membranes (NaA@CM) for oil/water separation were prepared using low-cost, readily available, and green metakaolin as the main raw material. The hydrothermal temperature was found to greatly affect the structure and properties of NaA@CM. The composite membrane prepared at 110 degrees C (NaA@CM-110) exhibited optimum underwater superoleophobicity, large water flux, and high separation efficiency for the cyclohexane/water mixture.

Summary: The risk-taking tendency in human decision-making can be positive and pro-social when it benefits others or society. Recent research has explored the mechanisms of individual negative risk and positive prosocial behaviors and introduced the concept of prosocial risky behavior, which involves risk-taking for the benefit of others. This behavior is dangerous yet prosocial, and understanding it can contribute to a better understanding of human development.

Summary: Ti doped ta-C films were deposited using a hybrid coating system and the microstructure, mechanical, and tribological properties of the films were investigated. The Ti content in the films increased linearly with increasing Ti target current, leading to the formation of TiC phase and a transformation of the microstructure to a nanocomposite structure. The Ti doping significantly affected the hardness, residual stress, and adhesion force of the films, resulting in improved friction coefficients and wear rates at different temperatures.

Summary: Vibrio alginolyticus is a significant conditional pathogen in marine aquaculture, causing economic losses. Temperature affects its quorum sensing (QS) system, and novel regulatory factors influencing LuxR expression have been identified. These regulators have temperature-dependent or temperature-independent effects on QS-associated phenotypes, such as Asp yields and biofilm formation, indicating their importance in population phenotype modifications. Further investigation is needed to understand their role in opportunistic outbreaks of vibriosis.

It was found that all the anisotropy parameters of the subnetworks contribute positively, except for the normal contact force of the weak subnetwork. The contribution weight of the strong subnetwork is significantly greater than that of the weak subnetwork and slightly decreases with increasing shear velocity.

Summary: Phage therapy is a potential alternative to antibiotics for bacterial infections. This study found that storing phages at 4 degrees C was optimal and that 10% dimethyl sulfoxide (DMSO) was more effective in protecting the phages at lower temperatures than glycerin. Additionally, the use of hydroxyapatite and a combination of trehalose with tryptic soy broth or skim milk powder alleviated phage inactivation during storage. Furthermore, a model for predicting phage shelf-life was established with high accuracy using the Accelerated Stability Assessment Program (ASAP) based on the Arrhenius equation.

Summary: By analyzing the impact of Beijing and Shanghai on global carbon emissions, it is found that they are net carbon consumers and play important roles in international trade. Structural adjustment has become the main factor in reducing carbon emissions, rather than technological progress. Beijing's carbon emissions continue to increase, while Shanghai's carbon emissions have declined. Both cities have stable and hub roles in the global carbon network. The heterogeneous structural characteristics of carbon emissions in these two metropolises highlight the need for different carbon mitigation strategies.
