Methods: Eighty K.\u0000pneumoniae isolates were obtained from 250 urine samples collected from patients in Baghdad Hospitals, Iraq, from November 2020 to March 2021.

One of the most pressing difficulties in the agricultural industry is the\u0000need to handle pesticide-related issues such as environmental contamination,\u0000bioaccumulation, and increases in insect resistance, which necessitates reducing\u0000the amount of pesticide sprayed on crops and protecting stored products. Nanotechnology is proving to be an appealing tool for achieving this goal since it provides new ways to synthesize and transport active ingredients known as nanopesticides 1\u0000. Nanoemulsions are particularly well suited to creating lipophilic\u0000functional agent delivery systems 2\u0000. The current study uses a high-energy (ultrasound) emulsification approach to create oil-in-water (O/W) acetamiprid\u0000nanoemulsions with synthetic and natural additives. The acetamiprid nanoemulsions were spontaneously formed by adding a mixture of acetamiprid and solvent\u0000in an aqueous solution containing a surfactant (tween) with continuous stirring.\u0000The nanoemulsions were then formed by ultra-sonication. Various characterization techniques for acetamiprid nanoemulsions include particle size analysis\u0000(DLS), Fourier-transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). Acetamiprid nanoemulsions are further evaluated by\u0000studying thermodynamic stability. This includes a Centrifugation assay, Freezethaw cycle nanoemulsions, Heating-cooling test, stability at room temperature of\u000025°C, pH measurement, and viscosity measurement. The droplet size and morphology of the acetamiprid nanoemulsions were measured by dynamic light scattering (DLS) and transmission electron microscopy (TEM). DLS and TEM\u0000measurements showed that acetamiprid nanoemulsions had an almost droplet size\u0000distribution (PDI < 200 nm). On this basis, an insecticide acetamiprid was incorporated into an optimized nanoemulsion system to demonstrate potential applications in pest control.\u0000Keywords: Acetamiprid nanoemulsion, nanoemulsion characterization,\u0000nanoemulsion stability.","PeriodicalId":443152,"journal":{"name":"Sumer 1","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129808443","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}
