“…Considering surface roughness and wettability in this study, increasing contact angles were observed with increased surface roughness. This data is also supported by Afida Jemat et al’s comparison of 3 biomaterials which showed that increased contact angles can also be found with higher surface roughness ( Jemat et al, 2018 ). Yu-Hua Pan et al, also showed in a comparison between control and GDP-treated zirconia disks that increased surface roughness is associated with higher contact angle ( Pan et al, 2020 ).…”

Introduction: To overcome the genuine bioinert properties of zirconia ceramic, functionalization of the surface with the bioactive protein fibronectin was conducted.Methods: Glow discharge plasma (GDP)-Argon was first used to clean the zirconia surface. Then allylamine was treated at three different powers of 50 W, 75 W, and 85 W and immersed into 2 different fibronectin concentrations (5 µg/ml and 10 µg/ml).Results and Discussion: After surface treatment, irregularly folded protein-like substances were attached on the fibronectin coated disks, and a granular pattern was observed for allylamine grafted samples. Infrared spectroscopy detected C-O, N-O, N-H, C-H, and O-H functional groups for fibronectin treated samples. Surface roughness rose and hydrophilicity improved after the surface modification, with MTT assay showing the highest level of cell viability for the A50F10 group. Cell differentiation markers also showed that fibronectin grafted disks with A50F10 and A85F10 were the most active, which in turn encouraged late-stage mineralization activity on 21d. Up-regulation of osteogenic related mRNA expression from 1d to 10d can be observed in RT-qPCR data for ALP, OC, DLX5, SP7, OPG and RANK biomarkers. These physical and biological properties clearly indicate that an allylamine and fibronectin composite grafted surface significantly stimulated the bioactivity of osteoblast-like cells, and can be utilized for future dental implant applications.

“…It was reported in a separate study that the effect of self-cleaning is the result of the twin effects of the surface roughness and hydrophobicity (Shirtcliffe et al 2010). A higher surface roughness contributed to a higher contact angle, and hence a higher hydrophobicity (Jemat et al 2013). The combined effect allowed the droplets to stay on the top of the surface and roll off together with the soil.…”

The biomimetic application was studied for banana leaves (Musa acuminata Colla), which have been commonly used as a traditional cleaning technique for ironing plates. In this study, banana leaf surfaces were subjected to horizontal sliding forces of 5 N, 10 N, 15 N, and 30 N, using a heated plate at 100 °C, 200 °C, 300 °C, and 500 °C. The self-cleaning behavior of the banana leaves was determined by measuring the adhesion force, roughness, and contact angle, which were subsequently correlated with the surface morphology. Based on the results of this study, the adhesion force decreased from 6.39 nN ± 0.42 nN at 100 °C to 0.50 nN ± 0.50 nN at 500 °C with a load of 30 N, whereas the roughness increased from 0.79 µm ± 0.21 µm at 100 °C to 1.12 µm ± 0.30 µm at 500 °C. Furthermore, the contact angle decreased from 124.8° at 100 °C to 104.0° at 500 °C with a load of 30 N. This study established that the morphology of the banana leaves was altered with the temperature during sliding, which correlated with the surface characteristics.

“…Titanium dioxide (TiO 2 ) coatings are widely used in biomedical applications and self-cleaning coatings owing to their wear and corrosion resistance, and biocompatibility. [1][2][3][4] However, TiO 2 coatings have drawbacks, such as failure caused by bacterial infection in biomedical applications, 5 and TiO 2 photocatalytic activity is limited within the visible region owing to low sunlight absorption. [6][7][8] Hence, various methods have been tested to overcome this problem, including mixing with different oxides such as zirconium oxide (ZrO 2 ) and stannic oxide (SnO 2 ) to increase the photocatalytic activity of TiO 2 .…”

Titanium dioxide (TiO2) powder mixed individually with 10 and 30 weight percentage (wt%) ZnO was thermally sprayed onto a grade B API 5 L carbon steel substrate by atmospheric plasma spraying. The effect of the addition of ZnO (10 wt% and 30 wt%) on the microstructures and wettability properties of the TiO2/ZnO coatings was investigated. The characterization of the coatings was carried out using scanning electron microscopy, X‐ray diffraction (XRD), laser confocal microscope, and sessile droplet system. The XRD analysis of the coating revealed that the anatase phase of TiO2 in the powder state transformed into rutile phases for the produced TiO2/ZnO coatings. Surface microstructure analysis revealed that the coatings had typical micro‐roughened surfaces of plasma spraying products. The coating with 30 wt% ZnO produced a coating with remarkable pores and microcracks compared with the TiO2 coating and coating with 10 wt% ZnO. Additionally, the increase in the wt% of ZnO increased the surface roughness value of the produced coatings and substantially changed the wettability properties of the TiO2 coating from hydrophilic to hydrophobic.
