Summary: In this study, a robust self-similar under-liquid dual super-lyophobicity anti-fouling cement was reported. This material demonstrated stable underwater super-oleophobicity and under oil super-hydrophobicity through a simple mixture of cement and water. It not only possessed good mechanical robustness, but also exhibited excellent antifouling property. The material maintained its superlyophobic functionality even after mechanical damages.

Summary: In this study, carbonaceous material (CM) prepared from refinery oily sludge was successfully used to remove butyl xanthate (BX) and diethyldithiocarbamate (DDTC) from synthetic wastewater. The results showed that CM had a high removal efficiency for both BX and DDTC, with the maximum adsorption capacity occurring at neutral pH. The coexistence of physical and chemical adsorption was confirmed by chemical analysis and characterization techniques, with physical adsorption being the main mechanism.

Summary: In this study, a magnetic material Nano-beta-CD@Fe3O4 was prepared by hydrothermal method and surface modification method. Nano-beta-CD@Fe3O4 can be intelligently enriched at the oil-water interface and oil-solid interface, and it can be stably dispersed to form nanofluid under the action of ultrasound. The experimental results showed that the best treatment effect for oily sludge was achieved when the concentration of Nano-beta-CD@Fe3O4 was 0.5%, the ultrasonic frequency was 60 Hz, and the temperature was 60℃.

Summary: Treatment of oily wastewater is crucial due to its threat to drinking water safety, the environment, and human health. A solar-driven device inspired by plant transpiration has been developed, showing high purification efficiency towards various nano/submicrometer-emulsion oily wastewaters. This device can also produce fresh water from oily seawater and acid-base-corrosion oily water, highlighting its potential in addressing oily wastewater treatment challenges.
