Another important property of Chinese anatase titanium dioxide is its photocatalytic activity, which enables it to break down organic pollutants and harmful chemicals when exposed to light. This makes it an attractive choice for applications in environmental remediation, such as air and water purification systems. Additionally, its photocatalytic properties have also been studied for use in self-cleaning surfaces, such as windows and building facades, where it can help to reduce maintenance costs and keep surfaces looking clean.

As mentioned above, these oxide NPs are harmful in part because both anatase and rutile forms are semiconductors and produce ROS. Particularly, P25 kind has band-gap energies estimated of 3.2 and 3.0 eV, equivalent to radiation wavelengths of approximately 388 and 414 nm, respectively. Irradiation at these wavelengths or below produces a separation of charge, resulting in a hole in the valence band and a free electron in the conduction band, due to the electron movement from the valence to conduction bands. These hole–electron pairs generate ROS when they interact with H2O or O2 [43,44]. It was described that they can cause an increase in ROS levels after exposure to UV-visible light [45]. The NBT assay in the studied samples showed that bare P25TiO2NPs produce a large amount of ROS, which is drastically reduced by functionalization with vitamin B2 (Fig. 5). This vitamin, also known as riboflavin, was discovered in 1872 as a yellow fluorescent pigment, [46] but its function as an essential vitamin for humans was established more than sixty years later, and its antioxidant capacity was not studied until the end of the XX century [47,48]. This antioxidant role in cells is partially explained because the glutathione reductase enzyme (GR) requires it for good functionality. This enzyme is the one in charge of the conversion of oxidized glutathione to its reduced form which acts as a powerful inner antioxidant and can quench the ROS [49,50]. The cost of this action is that the glutathione is converted to the oxidized form and needs to be recovered by the GR. Consequently, the cells need more vitamin B2. Another glutathione action is the protection against hydroperoxide. This activity is also mediated by riboflavin. Therefore, local delivery of this vitamin seems to significantly help the cells in their fight to keep the oxidative balance, once they are exposed to high levels of ROS.

  • Another advantage of using a 2-tier cooling rack is the improved airflow around your baked goods. Proper cooling is crucial to achieving the best texture and flavor in your treats. When items are spaced out on a single tier, airflow can be limited, leading to sogginess or uneven cooling. By utilizing a multi-tiered design, you ensure that air circulates freely around each item, allowing them to cool evenly and retain their intended texture. This is especially important for delicate pastries and cookies that require precise temperature management.
