“…Hence the droplet size distribution would be dominated by small droplets. Such a correlation among mixing energy, DOR, and the size of oil droplets had the same trend as experiments conducted under normal conditions ( Li et al, 2011a , Yang et al, 2021 ). Mukherjee et al (2012) reported an inverse dependency of oil droplet size on mixing energy during standard baffle tests.…”

Droplet size distribution of dispersed oil in deep-water is critical to the transport and biodegradation of spilled oil in deep-sea. Few studies have focused on the effects of pressure on chemically dispersed oil through experiments. This study thus simulated how the crude oil homogenously pre-dispersed by Corexit 9500A using baffled flasks would behave after being exposed to deep-water conditions. Key factors included dispersant-to-oil ratio (DOR), mixing energy (energy dissipation rate and Kolmogorov microscale), and pressure (up to 150 bar). The variations of pressure were demonstrated to have insignificant effects on the size distribution of pre-dispersed oil. Both the average and medium droplet sizes were correlated negatively with DOR and mixing energy in an established model with a p-value 0.0011. The log-normal and log-logistic distributions provided a reasonable fit to simulate the droplet size distribution. The two parameters of log-logistic distribution were dependent on DOR and mixing energy with a p-value < 0.005. The results would be valuable to advance the understanding of the behaviours and trajectories of chemically dispersed oil under deep-water conditions. The research helped provide more scientific evidence to improve the understanding of dispersed oil behaviours under high pressure and support deep-sea oil spill research and potential extension of the existing results from shallow water to deep water conditions.

With the rapid development of modern intelligent industry and the Internet of Things, the demand for multifunctional electromagnetic interference (EMI) shielding material has increased for complicated application scenes. Herein, derived from a hazardous waste, i.e., leather solid waste (LSW), a silver/LSW/poly(vinyl alcohol) (PVA) membrane has been prepared via resourceful combination of solids state shear milling (S3 M) and electroless plating technology. The debundled leather fibers prepared by S3 M can act as template for silver electroless plating and thus conductive Ag/LSW fibers with high aspect ratio and electrically conductive were achieved. Moreover, Ag/LSW fibers were integrated into film and sealed with PVA to form the Ag/LSW/PVA membrane. Owing to the high conductivity and mechanical performance of PVA, the Ag/LSW/PVA membrane (1.2 mm) exhibited EMI shielding (62 dB), mechanical robustness (tensile strength reached to 89.7 MPa), and Joule heating capability (56 s to 101.3 °C). Impressively, the multifunctional membrane exhibits great potential in future smart oil stations, where under the premise of satisfying high-efficiency electromagnetic shielding, the Ag/LSW/PVA membrane can effectively absorb heavy crude oil through the Joule heating and porous structure and achieve double protection for electronic devices.

“…It is hypothesized that dispersed oil may break into smaller droplets when entering the microchannels of frazil ice. The droplet size of dispersed oil in the water column and frazil ice was measured, respectively, using a laser in-situ scattering and transmissometer (LISST-200X) (Sequoia Scientific, Bellevue, WA) to verify the occurrence of oil breakup. The detailed measurement is shown in text S1.…”

Oil spills in the Arctic have drawn dramatic attention in recent years. Frazil ice, as the essential formation of sea ice, may affect the effectiveness of dispersants during oil spill response and the associated behaviors of dispersed oil. However, these impacts remain poorly understood, limiting the appropriate usage of dispersants in ice-covered regions. Herein this work explored the effects of frazil ice on the dispersion effectiveness of two dispersants (Corexit 9500A and hydrolyzed shrimp waste) and the migration of dispersed oil within frazil ice. We discovered that frazil ice inhibited dispersion effectiveness by attenuating water velocity. Permeable frazil ice encapsulated 11–30% of dispersed oil, implying a lower oil bioavailability. We thus proposed and verified a microscopic mechanism to unravel the migration of dispersed oil toward permeable constrictions in frazil ice. We predicted the concentration of dispersed oil encapsulated in frazil ice using bed filtration theory and verified the prediction through experiments. Furthermore, the presence of frazil ice can lead to the breakup and coalescence of dispersed oil. Overall, our findings would facilitate the appropriate planning and decision-making of dispersant-based oil spill response and a better understanding of the fate of dispersed oil in the frazil ice-infested ocean.
