Applicazioni

  • Agglomeration of celecoxib by quasi-emulsion solvent diffusion method without stabilizer: effect of good solvent.: This research explored the agglomeration of celecoxib using the quasi-emulsion solvent diffusion method, highlighting the role of methyl acetate as a good solvent to improve particle size and distribution without the need for stabilizers (Maghsoodi & Nokhodchi, 2018).
  • Formulation and in vitro evaluation of ketoprofen in palm oil esters nanoemulsion for topical delivery.: The formulation and evaluation of ketoprofen in a nanoemulsion system for topical delivery were examined, with methyl acetate used as a solvent to enhance solubility and stability of the active ingredient (Sakeena et al., 2010).
  • Preparation of surfactant-free nanoparticles of methacrylic acid copolymers used for film coating.: This paper presented a method for preparing surfactant-free nanoparticles using methyl acetate as a solvent, emphasizing its role in the formation of uniform nanoparticle dispersions for coating applications (Nguyen et al., 2006).

Traditional fluorescence-based tags, used for anticounterfeiting, rely on primitive pattern matching and visual identification; additional covert security features such as fluorescent lifetime or pattern masking are advantageous if fraud is to be deterred.

Several serine hydrolases catalyze a promiscuous reaction: perhydrolysis of carboxylic acids to form peroxycarboxylic acids. The working hypothesis is that perhydrolases are more selective than esterases for hydrogen peroxide over water. In this study, we tested this hypothesis, and focused
