Compared with the Ni coating, the corrosion resistance of the Ni-Cu alloy coating has been significantly improved, with the corrosion potential Ecorr and the corrosion current density Icorr of -246 mV and 0.9 μA·cm-2, respectively. The results show that alloying can effectively prolong the incubation period of pitting nucleation and improve the self-healing ability of coating. The structure and microstructure of the coating show that the surface of the Ni-Cu coating is flat and the grains preferentially grow along the (111) close-packed surface, which also makes the coating have higher densification and significantly reduces the number of self-corrosion sites and corrosion tendency of the coating. The lower binding energy Cu2O produced by Ni-Cu coatings at the initial corrosion stage can reduce the formation of metal cation holes and prolong the incubation period of pitting corrosion. After pitting formation, the corrosion products Cu2O and Cu2(OH)3Cl of Cu in the pitting hole have a certain hindrance to corrosion and are conducive to promoting passive reconstruction, which is an important reason for the Ni-Cu alloy coating shows higher self-healing ability and higher corrosion resistance.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, such coatings are effective against various ways of spreading the bacterial cells, be it through the deposition of an aerosol created when patients cough or sneeze, or through contact transfer by patients’ hands. In this review, we briefly summarize the existing strategies for producing materials with extreme wettability by aqueous media and overview their main characteristics. Then the mechanisms behind the bactericidal effect of these materials are discussed in detail jointly with the analysis of some examples of testing the antibacterial efficiency of extreme wettability surfaces.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141656690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This multilayer configuration has a surface with increased roughness and absorption area. The valleys were porous materials, which were connected to an underlying metallic sub-layer that is susceptible to corrosion. In turn, this corrosion induced changes to the top layer. The Ni-P layer was deposited by the electroless technique using an acid nickel sulfate bath as a source of metal ions and a reducing agent of sodium hypophosphite. Etching initiated an oxidation process on the surface, forming a layer of amorphous black nickel oxide for absorption. The surface features of the black Ni-P double layer consist of an uneven surface that aids sunlight adsorption. Carbon steel (AISI 1018) with different surface finishes was used for depositing Ni-P and black Ni-P, aiming to establish correlations with solar adsorption. The sample with an increased surface roughness obtained a higher absorption percentage than a single layer. The corrosion rate was calculated as 7 mmpy for the black Ni-P layer by applying polarization curves.

They serve as crucial tools in retinal detachment surgery, acting as both intraoperative aids and short-term tamponade agents. However, the interactions between PFCLs and the retinal surface are not fully understood, limiting insights into potential complications. This study investigates the interfacial interaction between perfluorodecalin (PFCL) and the retinal surface. Wetting behavior of animal retinas by water and PFCL was analyzed, revealing water droplets’ floating phenomenon in PFCL and calculating the critical radius for this effect. Dynamics of water spreading over the retina were examined. A model experiment demonstrated that water’s tendency to float over PFCL, interacting with a hydrophilic surface like the retina, could create traction and damage the retinal surface. These findings enhance our comprehension of physical processes at the PFCL/retina interface and offer practical insights for improving ophthalmic surgical procedures.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141273489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While exfoliating graphite to graphite nanosheets holds substantial theoretical potential for significantly enhancing AIBs battery performance, traditional redox strategies have the drawback of introducing defects and functional groups. In this work, graphite nanosheets exfoliated by supercritical carbon dioxide for high-performance aluminum-ion battery cathodes exfoliated by supercritical carbon dioxide (GNS-20) was firstly explored for AIB cathodes. Electrochemical tests show that the specific capacity of GNS-20 for AIB cathode was 152 mAh g−1 at a current density of 4 A g−1 during 1000 cycles, which was 1.9 times higher than that of natural graphite (NG) and 1.47 times higher than that of defect-rich reduced graphene oxide (rGO). Further, the regulation of the interlayer pore structure of GNS-20 proved instrumental in enhancing its AIB performance. Modulating the porosity of graphite nanosheets by adjusting the exfoliation pressure had a significant impact. The porosity of graphite nanosheets at an exfoliation pressure of 20 MPa was 86.7%. While the porosity at 15 MPa was 71.5% and 69.7% at 10 MPa, corresponding to capacities of 117 and 99 mAh g−1 (4 A g−1), respectively. This approach simplifies the process and aligns with environmental principles, offering significant potential for various graphite nanosheets applications.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140971599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid silica coating was then applied to the T/C fabric to develop a highly efficient FR-coated T/C fabric with improved washing durability. The surface morphology, size distribution, and condensation degree of the hybrid silica sol particles were characterized. The thermal stability, heat release, flame retardancy, and mode of action of the coated T/C fabrics were also investigated. The coated T/C fabrics exhibited self-extinguishing performance, with the damaged length decreasing from 30 cm to 8.5 cm and the LOI increasing from 17.1% to 30%. The desirable flame retardancy of the coated T/C fabric was well maintained even after 10 washing cycles. The remarkably inhibited heat release ability suggested a decreased fire hazard.
