Summary: Nanomaterials loaded with corrosion inhibitors have the potential to achieve self-healing anticorrosion coatings, but the uncontrolled passive release of inhibitors presents challenges for scalable anticorrosion applications. In this study, a strategy for regulating the pH-responsive behaviors of a polydopamine delivery system was proposed to enhance corrosion inhibition effects in different environments. By controllable group tailoring, the delivery system showed enhanced corrosion inhibition effects in acid or alkaline environments. The study is significant for the design of pH-responsive smart coatings for scalable applications in different environments.

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 protective behavior of ZrO2-3%molY(2)O(3) sol-gel coatings on 9Cr-1Mo P91 steel was evaluated using corrosion monitoring sensors. The results showed that the coating effectively limited the transport of ions and slowed down the corrosive process, reducing the corrosion rate of the steel. The proposed sol-gel coatings are a viable option to mitigate corrosion in concentrated solar power plants.

Summary: In this study, two leachable anticorrosive pigments, cerium 4-hydroxycinnamate (Ce(4OHCin)3) and strontium zinc phosphosilicate (SZP 391), were incorporated separately into model organic coatings to protect the structural integrity of AA2198-T851 aluminum alloy under neutral salt spray and immersion test conditions. The protective films formed through the dissolution and release of inhibitor clusters from the coatings, which provided channels for the transport of inhibitive species. The protective films revealed a monolayer structure, and their inhibitive properties were confirmed by increased impedance modulus of the substrate.

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.

It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.
