In addition to the toxic effects of TiO2 NPs, discussed in previous chapters, these NPs have been also shown to promote photosynthesis and nitrogen metabolism, resulting in the enhanced growth of spinach. It increases the absorption of light and accelerates the transfer and transformation of the light energy. It was also found that treatment with nano-sized TiO2 significantly increased the level of antioxidant enzymes, and decreased the ROS accumulation and malonyldialdehyde content in spinach chloroplasts under visible and UV irradiation. TiO2 NPs also increased the superoxide dismutase activity of germinating soybean, enhanced its antioxidant ability, and promoted seed germination and seedling growth.

The production process of lithopone involves a sophisticated synthesis of zinc sulfide and barium sulfate, resulting in a pigment that boasts high whiteness, opacity, and heat stability. The ratio of ZnS to BaSO4 can be adjusted to cater to specific applications, with some formulations containing up to 70% zinc sulfide and 30% barium sulfate. This flexibility makes lithopone an adaptable solution for manufacturers seeking optimal performance in their products.
