Novel in vitro and ex vivo models were created for studying the physical properties of the retinal surface and interfacial spreading of the ophthalmic drugs over retinas. In vitro model experiments showed that droplets of all tested drugs sank rapidly in the silicone oil to contact with the plasma-treated glass, and then rapidly spread over the glass surface. In the ex vivo model, the migration phase was followed by contact with, and rapid spread/absorption by the retinal interface. The wetting behavior of drugs under contact with the glass substrate and retinas was similar. Characteristic time scales of drugs spreading, controlled by the viscous dissipation, were close. All tested drugs migrated to the retinal surface and rapidly spread across the retinal surface. This suggests that intravitreal drugs might be used effectively in eyes filled with a silicone oil tamponade, as they rapidly migrate to, and spread over the retinal surface.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43467135","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}

Herein, this work fabricated a radiative cooling porous film with superhydrophobic self-cleaning using poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly (vinylidene fluoride) (PVDF). The PVDF-HFP/PVDF film consists of micropores with nanoparticles both inside and at the surface. The micro/nanostructures enhanced the scattering of solar light, which in combination with the infrared emissivity of both PVDF-HFP and PVDF polymers makes the film show excellent radiative cooling ability with a sub-ambient temperature drop of 16°C. The micro/nanostructures roughened the surface of the film, which in combination with the low surface energy property of both PVDF-HFP and PVDF polymers endows the film with superhydrophobic self-cleaning property. The self-cleaning function defends the film from contamination and maintain sustainable radiative cooling for lasting applications. The integration of cooling and self-cleaning into a film paves a way to multifunctional and long-life radiative cooling materials.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47529345","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}

In this study, Al2O3 ceramic coating was synthesized on the surface of 2D quartz fiber fabric in aqueous solution near room temperature. Surface morphology and chemical composition were studied to evaluate the quality of the coating by SEM, AFM, XPS and FT-IR. The annealing behavior at high temperature was evaluated by electronic universal testing machine after high temperature processing. Al2O3 coating could improve its annealing behavior effectively. The maximum load that the coated fabric can bear was 2.5 times as higher as that of the original fabric, proving the superior high temperature mechanical property of the coated fabric. The coating on the surface of the fiber could block the damage of the high temperature to the quartz fiber, improving the crystallization phenomenon of the quartz fiber at high temperature, followed by the improve in the high temperature mechanical property of the fabric.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43173377","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}

It is known that water condensation on graphene leads to a change in the electrical properties and affects the graphene sensor sensitivity. To date, there is no data on the effect of temperature on surface properties of graphene synthesized on copper. It is shown for the first time that a change in the crystal orientation of copper (111), (110) and (100) leads to different structuring of water on copper and on graphene layer. An increase in temperature alters the density of water distribution and the pattern of water structuring. The analysis of the influence of grain boundaries on graphene synthesis is given. A change in the size of defects is shown to alter the qualitative nature of roughness for copper and graphene. Various methods of roughness processing allow us to explain the inconsistency of existing works comparing the roughness of the metal and graphene coating. The roughness measurement serves to prove our previously proposed hypothesis about the local stratification of graphene and copper due to large surface defects. The results obtained are important for the development of graphene-based sensor technologies.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46689579","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}

TC4 substrate, undoped MAO sample and optimally doped MAO sample were oxidized at 650°C, 750°C and 850°C respectively. The results show that the best doped MAO samples show excellent high-temperature oxidation resistance at three temperatures. Compared with the undoped MAO sample, the maximum oxidation weight gain per unit area of the optimally doped MAO sample decreased by 10.8%, 19.6% and 22.1%, respectively. This is mainly because the thickness, hardness and adhesion of MAO coating are all increased by doping CeO2 particles, and a dense protective layer can also be formed on the surface of TC4 substrate. The invasion of oxygen medium is effectively prevented.

The results shown that the microgroove arrays oriented perpendicular to the flow direction were beneficial to drag reduction, and the drag reduction rate of up to 7.2% was obtained. Meanwhile, the microgroove arrays induced by laser ablation changes the wettability of paint surface to hydrophobicity. The contact angle (CA) shows a slightly decrease trend with the increase of the periodic scale. Besides, the anticorrosion properties of these microgrooves make them advantageous in harsh environments. The fabricated drag-reducing paint microstructures, with the features of self-cleaning and durability, have the potential to be applied on vehicles to realize speed improvement and energy saving.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46002426","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}

In this system, the preparation of high-quality photoanode is essential for achieving efficient solar hydrolysis. Polymeric carbon nitride has emerged as a promising photocatalyst for solar water splitting due to its visible light absorption, suitable band edge positions and good chemical stability. However, considerable difficulties have been encountered for the preparation of robust and well-bonded carbon nitride films on conductive substrates. Herein, a combined strategy of electrophoresis and vapor deposition results in robust and high performing carbon nitride film photoelectrodes with good bonding on substrates, suitable thickness for light absorption, and enhanced charge separation and transfer abilities. The unique structure of the photoanode thus facilitates the oxidation of water and leads to an optimal photocurrent density of approximately 120 μA cm-2 at 1.23 VRHE.

The color stability yield by the surface plasmon resonance mates the commercial requirement in items of colorfastness ratings of 3-4 for wash, 4 for light, 4-5 for dry rubbing, and 3-4 for wet rubbing. These findings established that this treatment successfully endowed OCFs with long-lasting antimicrobial capabilities and thermal stability due to the interaction with the microparticles.
