Summary: In this study, a ZnO thin film coating on an aluminum substrate was investigated. Zn thin layers were electroplated and thermally oxidized to synthesize the ZnO thin films. The samples were characterized using various techniques and it was found that the films showed different morphologies and surface roughness depending on the annealing time. The synthesized films exhibited both hydrophobic and hydrophilic surfaces, with the sample annealed for 2 hours at 500°C showing the highest contact angle.

Summary: The oscillation behavior of liquid droplets on a hydrophobic mesh surface is different from that on a flat hydrophobic surface with the same contact angle. Higher sonic excitation frequencies lead to larger displacement of the droplet in both vertical and horizontal planes, with vertical displacement being larger. The maximum displacement of the droplet surface is greater on a flat hydrophobic surface compared to a mesh surface.

Summary: This study investigated the effects of surface roughness and surface energy on reducing dust adhesion on PV panels by preparing coatings with different wettability. It was found that the high surface energy of superhydrophilic coatings played a significant role in resisting dust adhesion, while further reducing surface energy on other coatings had limited impact on improving dust-proof ability. Additionally, large airflow velocity was beneficial for resisting dust adhesion for all types of coatings, but had limited effect on improving the anti-soiling effect of superhydrophilic coating under different tilt angles compared to other three coatings.

Summary: The study showed that ZSM-5 zeolites with higher Si/Al ratios and abundant hydrophobic Si-O-Si linkages exhibit higher catalytic activity in the ketalization of glycerol. The hydrophobic zeolites with lower affinity for glycerol help improve the interfacial solubilization of glycerol/acetone near the active sites, enhancing the catalytic action.

Summary: Investigating the interfacial properties between water and graphene is crucial for various applications due to the influence of the water-carbon interface. The study successfully detected water vapor adsorption on several layer graphene using a lab-made adsorption apparatus. The water-graphene interaction energy increased with increasing water amount, leading to a transformation in water structure and hydrophilic behavior on graphene interfaces.

Summary: Reusable soft contact lenses continue to be popular among wearers, but the additional steps required for cleaning and disinfecting may lead to non-compliant behavior and potentially impact wearers' health. Educating patients, regulating the use of contact lens care solutions, and reevaluating global standards are key strategies to better support contact lens wearers.

Summary: This study examined the impact of incubation time, lipid concentration, and ATS replenishment on the uptake of phosphatidylcholine onto CH and SH contact lens materials. The results showed that all materials exhibited increasing PC deposition over time, with SH materials having higher uptake rates than CH materials. Increasing lipid concentration in the ATS resulted in increased PC binding onto the contact lens materials, while regular replenishment of the ATS showed different impacts on PC deposition for CH and SH materials.

Summary: This study investigated the uptake of four pro-inflammatory cytokines onto six contemporary contact lens materials. It was found that both conventional hydrogels and two of the four silicone hydrogels tested showed some uptake of certain cytokines, while senofilcon A and somofilcon A did not exhibit uptake of any. Overall, the tested contact lens materials did not show significant uptake of IL-6 and had limited uptake of IL-1 beta, IL-8, or TNF-alpha.

Summary: Contact lenses in the future may have functions beyond correcting refractive errors, such as detecting systemic and ocular diseases, treating various eye conditions, correcting presbyopia, and controlling the development of myopia. Advancements in technology have led to the development of contact lenses as drug delivery devices and powered through nanotechnology. Challenges remain in integrating sensors into contact lenses and optimizing drug delivery to the ocular surface.

Summary: This study aimed to evaluate the release profiles of two drug-loaded contact lenses (CLs) in a 3D in vitro eye blink model and compare them with in vivo profiles. The results showed that the release of both drugs was more sustained and lower in the 3D eye model compared to in vitro release in vials. The findings suggest that the current 3D printed eye blink model could be a useful tool to measure the release of ophthalmic drugs from medicated CLs, but further optimization is needed.

Summary: The lifestyle choices of contact lens wearers can have negative impacts on eye health, such as poor adherence to care, sleeping in lenses, inappropriate purchases, lack of regular aftercare visits, wearing lenses while feeling unwell, wearing lenses too soon after surgery, and wearing lenses during risky behaviors. However, contact lenses can also provide therapeutic benefits. The COVID-19 pandemic introduced new challenges for contact lens wearers, including mask-associated dry eye, increased discomfort from digital device use, accidental exposure to hand sanitizers, and reduced lens usage.
