Application


  • Insight into the Morphology-Dependent Catalytic Performance of CuO/CeO(2) Produced by Tannic Acid for Efficient Hydrogenation of 4-Nitrophenol.: Examines the catalytic performance of CuO/CeO2 nanoparticles synthesized using tannic acid, focusing on their efficiency in hydrogenating 4-nitrophenol (Ye et al., 2021).

  • Proteomic analysis deciphers the multi-targeting antivirulence activity of tannic acid in modulating the expression of MrpA, FlhD, UreR, HpmA and Nrp system in Proteus mirabilis.: This research deciphers how tannic acid modulates the expression of several virulence factors in Proteus mirabilis through proteomic analysis (Durgadevi et al., 2020).
