The thin plate-like ZnO photocatalyst exhibited the hexagonal phase with the energy band gap of 3.04 eV. Under UV light irradiation, the prepared ZnO photocatalyst showed 94% and 90% removal of reactive red 141 (RR141) azo dye and oxytetracycline (OTC) antibiotic, respectively. Interestingly, the enhanced photocatalytic performance of 97% and 93% toward degradation RR141 and OTC, respectively, was obtained under natural sunlight irradiation. The removal of the pollutants agrees well with the first-order kinetic model showing the rate constant of 0.043 min<sup>−1</sup>. This demonstrates the promising role of the synthesized ZnO photocatalyst for environmental protection. Furthermore, the prepared ZnO was also used for the treatment of pig manure as a novel strategy for house fly control. The treatment of pig manure with ZnO had little effect in a choice test but strongly inhibited oviposition in a no-choice test, significantly lowering the number of eggs laid. Although the treatment did not affect survival rates or development times, it imposed significant sublethal fitness costs: larvae reared on treated manure were significantly smaller, and the resulting adult population had a lower female-to-male ratio. These effects were linked to a suboptimal protein-to-carbohydrate ratio in the treated manure. Chemical analysis confirmed that the treatment altered the manure's volatile profile, reducing key attractants like butanoic acid and ammonia. The treatment of pig manure with the prepared ZnO constrains house fly populations through a dual mechanism: inhibiting oviposition and reducing the fitness of subsequent generations. This approach represents a promising and sustainable tool for integrated pest management in livestock environments.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"12 ","pages":"Article 100621"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has focused its attention on chromatic parameters, fabric properties, the UV protection factor, and antibacterial activity. The variables associated with the process of dyeing included time, temperature, pH, and Material: Liquor (M: L) ratio, which have been systematically optimized. Optimum conditions identified at 100 °C, pH 4.8, 60 min, and an M:L ratio of 1:30. In such conditions, nylon fabric showed improved coloration with greater K/S values, CIELAB color coordinates, and good shade repeatability.

The FTIR revealed good hydrogen bonding interactions between the dye and nylon polymer chains. The colored textile demonstrated good UV protection factor, which improved from 12.1 to 87.62 UPF values, meeting specific demands for high UV protective application in functional textile products for protective and healthcare apparel due to its phenolic compounds found in Babool bark.
