Summary: Superhydrophobic coatings are becoming increasingly popular due to their low maintenance requirements, high durability, and wide range of potential applications. These coatings can provide resistance to fouling, icing, smear, and corrosion, as well as the ability to separate oil from water. Consequently, the development of superhydrophobic materials is a topic of significant interest among academics worldwide. In this paper, a spray-coating deposition technique is utilized to deposit silica nanoparticles on glass using a sol-gel as a base. The resulting coating significantly increased transmittance to 99% at 600 nm. Water contact angle (WCA) and scanning electron microscopy (SEM) analysis of the coated layer's grade index and induced porousness demonstrated superhydrophobic behavior with a water contact angle exceeding 158 degrees.

Summary: The concentration of catalyst has a significant impact on the synthesis and properties of polyisocyanurate-polyurethane aerogels, leading to the production of low-density materials with high porosities. By reducing the catalyst amount, the size of scattering centers, particles, and pores decreases, resulting in the creation of the first transparent aerogels in this system. These transparent aerogels have potential applications in solar collectors, glazing systems, and sensors.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
