Abstract: A photochromic material can include nanoparticles of lanthanide-activated strontium aluminate (NLSA) embedded into polyethylene terephthalate (PET). The PET may further include electrospun polypropylene nanofibers (PPNF) incorporated therein. In some embodiments, the photochromic material may be transparent. In other embodiments, the photochromic material may be scratch resistant. In some embodiments, the photochromic material may be configured to form concrete. In still other embodiments, the photochromic material may be configured to form windows. The electrospun polypropylene nanofibers may be a roughening agent in the PET. The photochromic material may exhibit a green coloration after exposure to ultraviolet (UV) light. The NLSA may have a diameter of about 80 nm to about 120 nm. The PPNF may have a diameter of about 75 nm to about 180 nm. The photochromic material may be superhydrophobic.

Abstract: The acid-induced steel corrosion inhibitor based on rotten eggs provides a corrosion inhibitor that is biodegradable, has low toxicity, is water-soluble, easily produced, and is low-cost through the use of waste material, namely, white eggs (EWs). The corrosion inhibitor is added to a corrosive medium in an aqueous medium to protect the metal surfaces and steel interfaces on metal production equipment, such as pumps, tubing, and casing. The corrosion inhibitor based on rotten white eggs is loaded with metal nanoparticles (EWMNPs). The eco-friendly less destructive corrosion inhibitors based on metal nanoparticles synthesized with rotten white eggs are efficient to protect steel from corrosion, while still dissolving in oil streams produced without or with salt water and being soluble in acidic mediums containing chlorides. The corrosion inhibitors have low toxicity to marine life when discharged into the ocean, thereby protecting the marine life, particularly near the system's drain.
