  Foliar application of nano-zinc oxide crystals improved zinc ...

  2022313 · Lower levels of zinc in the food lead to Zn deficiency in the local population of Pakistan. The study aimed to increase the Zn fraction of an edible vegetable for which in-house fabrication of nano-Zn oxide crystals was performed using the sol–gel method. The synthesized nano-crystals exhibited ~ 25 nm diameter, and the XRD peaks indicated a …
