Summary: In this study, Al2O3 ceramic membrane was modified to be hydrophobic by grafting 1H, 1H, 2H, 2H-per-fluorodecyltriethoxysilane, and its properties were characterized in detail. The CO2 capture performance of the modified ceramic membrane was investigated through experiments. Results showed that the wetting resistance of the modified membrane was significantly improved, and the contact angle increased from 49.8 to 130.9 degrees. With the use of ethanolamine (MEA) as an absorbent, the CO2 mass transfer rate and capture efficiency using the modified hydrophobic ceramic membrane were greatly increased compared to the original membrane. After 72 hours of immersion in MEA solution, the quality and pore size of the ceramic membrane did not show significant changes. This study provides valuable insights for the industrial application of gas-liquid membrane contactors with ceramic membranes for CO2 capture.

Summary: This paper proposes a dynamic modelling of two-lane pavement photovoltaic arrays based on cellular automata theory, and explores the influence of random vehicle shadows on the output characteristics. A mathematical model of two-lane pavement PV arrays considering bypass diodes and blocking diodes is established. An asymmetric two-lane Nagel-Scheckenberg (ATNS) model is introduced to characterize the change of irradiation intensity caused by vehicle shadows. Simulations and experiments show that the slowing probability and shading degree significantly affect the output characteristics, and the dynamic random vehicle shadows result in a changing multi-peak state of the power-voltage curve.

Summary: This study analyzes the factors influencing hydrate re-formation characteristics by simulating two-phase flow in hydrate sediment. The results show that temperature and pressure exhibit three stages of change in the water-dominated two-phase flow process. A lower effective sectional velocity of water enhances the hydrate re-formation process. Meanwhile, the gas phase impedes mass transfer on the water-hydrate interface and acts as a nucleation site to promote hydrate re-formation. The onset time of flow blockage is linearly positively correlated with the effective sectional velocity of water, but the amount of hydrate re-formation decreases with increasing velocity.
