An anti-icing surface has been designed and prepared with an aluminum panel by creating an artificial lotus leaf which is highly hydrophobic. The hydrophobicity of a solid surface can be generated by decreasing its surface tension and increasing the roughness of the surface. On a highly hydrophobic surface, water has a high contact angle and it can easily rolls off, carrying surface dirt and debris with it. Super-cooled water or freezing rain can also run off this highly hydrophobic surface instead of forming ice on the surface, due to the reduction of the liquid-solid adhesion. This property can also help a surface to get rid of the ice after the water becomes frozen. In this study, a Cassie-Baxter rough surface was modeled, and an aluminum panel was physically and chemically modified based on the modeled structure. Good agreement was found between predicted values and experimental results for the contact and roll-off angles of water. Most importantly, by creating this highly hydrophobic aluminum rough surface, the anti-icing and de-icing properties of the modified surface were drastically improved compared to the control aluminum surface, and the cost will be reduced.

Non-fungible token (NFT) is a digital asset whose ownership can be validated and controlled via blockchain technology. The NFT market is a rapidly growing field, and the rarity of NFT is an essential factor that affects its price, as scarcity leads to higher demand. This study focuses on the BAYC NFT collection, which is a successful and representative collection of profile picture NFT, and analyzes how rarity affects NFT prices. This paper investigates the relationship between the rarity and price of the BAYC NFT collection using formal concept analysis (FCA) method. The results show that rarity is a major factor influencing the price of NFT and the effect is more apparent in the medium rarity range. When rarity is very high or very low, other factors become significant determinants, such as the uniqueness and appeal of NFT, and even the naturalness of NFT images. This research highlights the importance of considering rarity when assessing NFT and underscores the need for a comprehensive evaluation of NFT rarity. This study also provides valuable insights into the NFT market and can be useful for NFT investors, creators, and collectors. Furthermore, the usefulness of FCA as a tool for quantifying NFT rarity and evaluating NFT price was demonstrated.
