Aplicação

  • 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. Herein, we present an electrohydrodynamically printed unicolour
