In natural subsurface formations like carbonate and shale, mixed wettability is frequently observed, characterized by heterogeneous regions at the pore scale that exhibit both hydrophilic (water-wet) and hydrophobic (oil-wet) characteristics. Despite its common occurrence, the impact of mixed wettability on immiscible fluid displacement at the pore scale remains poorly understood, creating a gap in effective modeling and prediction of fluid behavior in porous media. The primary objective of this study was to investigate how mixed wettability affects pore-scale fluid displacement dynamics, utilizing microfluidic devices designed to replicate rock-like structures with varied wettability properties. Current techniques for achieving mixed wettability within microfluidic devices often struggle with spatial control and resolution, limiting their accuracy. To address this limitation, a novel approach was employed that combined photolithography and molecular vapor deposition of perfluorodecyltrichlorosilane to precisely and selectively modify wettability within specific pore regions, achieving a mixed wettability distribution correlated with pore size for the first time. The experimental setup included five identical micromodels representing distinct wetting conditions, which were initially saturated with air and subsequently flooded by water. By systematically varying the ratio of hydrophilic to hydrophobic areas, we covered a range from fully hydrophilic to fully hydrophobic and intermediate mixed wettability configurations. Comparative displacement experiments revealed that pore-level mixed wettability has a pronounced effect on fluid displacement behavior, influencing the injection time, spatial invasion patterns, and dynamic pressure profiles. Results indicated that both the injection time and dynamic pressure decreased with an increase in the hydrophilic area fraction. Each wettability configuration displayed unique sequences of pore-filling events, emphasizing the critical role of the wettability distribution in influencing displacement dynamics. While mixed wettability exhibited a clear monotonic effect on invasion time and dynamic pressure, saturation behavior was notably nonmonotonic. Interestingly, mixed wettability scenarios with relatively medium to high hydrophilic fractions demonstrated enhanced overall sweep efficiency compared to the hydrophobic case and reduced the bypassed gas phase relative to the hydrophilic case. However, inefficiently distributed mixed wet zones were found to reduce the sweep efficiency. These findings highlight the critical influence of mixed wettability in fluid displacement processes, with significant implications for applications in oil recovery, CO₂ sequestration, and other subsurface energy technologies.</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"69165-69179"},"PeriodicalIF":8.3,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conventional test for its corrosion durability, known as the \"HOT/WET test,\" requires considerable time and effort and does not provide any local information about the corrosion. Here, we address this issue by employing open-loop electric potential microscopy (OL-EPM), a potential measurement technique based on atomic force microscopy (AFM), for corrosion inspection. To explore the applicability of OL-EPM, we observed the surface of the HDMs with different COC thicknesses in a dilute HNO₃ solution. Through time-dependent and high-resolution OL-EPM observations, we found that this technique can be used for detecting nanoscale COC defects. This is because the HDM surface under a COC defect is exposed to the solution and undergoes anodic dissolution, increasing the local potential around the defect. This is readily detected by OL-EPM even before corrosion product formation around the defects induces the topographic change. This work demonstrates that OL-EPM is useful not only for understanding the local corrosion mechanisms but also for detecting the COC defects in a much shorter time (∼3 h) than the HOT/WET test (3-4 days).</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"70020-70027"},"PeriodicalIF":8.3,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To specifically address this issue, we successfully synthesized nitrogen-doped carbon-coated halloysite nanotubes (HNT@NC) using a one-step sintering method and modified the Celgard 2325 separator on the side facing the sulfur cathode (HNT@NC-Separator). The study found that HNT@NC-Separator exhibits excellent electrolyte wettability and superb mechanical strength. Its surface has abundant polar sites that effectively capture lithium polysulfides, thereby improving the cycling and rate performance of Li–S batteries. At a current density of 0.2 C, the Li–S battery assembled with the HNT@NC-Separator achieved an initial discharge capacity of 840.8 mAh g^–1, maintaining a capacity of 486.1 mAh g^–1 after 100 cycles.

The demanding wound microenvironment, marked by heightened glucose levels, local exudate, and bacterial infections, emphasizes the pressing demand for advanced wound dressings to meet escalating clinical needs. Herein, a Janus wound dressing with an integration of an antimicrobial hydrophobic nanofiber layer and a 3D hydrophilic sponge was designed and prepared to manage and utilize wound exudate. The hydrophobic layer skillfully combined electrospun poly(ε-caprolactone) (PCL) nanofiber membranes (ENMs) and metal–organic frameworks (MOFs) with peroxidase-like properties by solvent etching, and glucose oxidase (GOx) was grafted through ligand interaction. GOx acts to consume glucose while modulating pH, thus suitable pH and self-supplied H₂O₂ were able to activate the catalytic activity of MOFs to generate ^•OH. Additionally, hydrophilic 3D sponges are constructed using gas foaming technology, which are tactfully combined with hydrophobic ENMs to form a Janus structure, which can transport exudate through the antimicrobial layer to the sponge layer, while sufficient glucose contact with GOx enhances the antimicrobial properties of the designed Janus wound dressing. Experimental results demonstrate the effectiveness of the cascade effect of GOx@PCL/MOF ENMs, ultimately releasing reactive oxygen species and exhibiting robust antibacterial properties. In vivo animal experiments reveal the ability of the Janus wound dressing to mitigate methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) infections in the early stages, thereby expediting the wound healing process. In vivo animal study, the Janus wound dressing achieved a healing rate of 54% on day 3.
