In conclusion, LNG plays a crucial role in the contemporary energy landscape, offering a cleaner alternative to traditional fossil fuels. As countries worldwide seek to balance energy demands with environmental responsibilities, LNG's role as a bridge fuel becomes increasingly vital. While it presents certain challenges, its benefits cannot be overlooked. Addressing these challenges effectively will be essential for realizing the full potential of LNG in supporting a cleaner and more sustainable energy future.

  • Titanium Dioxide Precipitation A Comprehensive Guide
  • What is Titanium Dioxide?
  • Titanium dioxide is primarily used as a pigment in oil-based paints and coatings. Its high opacity and ability to provide superior whiteness and brightness make it an ideal choice for enhancing the appearance of pipelines, storage tanks, and machinery in oil refineries. These facilities often operate in harsh conditions, and the durability and weather resistance offered by TiO2-coated surfaces ensure longevity and minimal maintenance.

  • In conclusion, titanium dioxide is a versatile and widely used chemical compound with a range of applications in various industries. Its excellent whiteness, opacity, chemical stability, and cost-effectiveness make it an attractive option for manufacturers looking for high-quality, durable products. As demand for titanium dioxide continues to grow, it is likely that we will see even more innovative uses for this versatile compound in the future.
  • The toxicity of P25TiO2NPs was evaluated in both prokaryotic (Fig. 3) and eukaryotic cells (Fig. 4). The XTT assay was chosen to measure the cell viability in bacterial cultures of MSSA, a normal skin microbiota microorganism. The reduction in the viability of samples with bare NPs is notorious, possibly due to the described ROS production from the interaction of P25TiO2NPs with light [37]. This effect seems to be avoided when they are functionalized with vitamin B2. Also, the most concentrated vitaminB2@P25TiO2NPs sample (0.2 mg/mL) shows up to 60% more absorbance after 6 h compared to the bare NPs (due to normal cell replication). This may indicate that the antioxidant effect of the vitamin B2 coating is greater than the oxidation damage produced by the NPs. This protective capacity could be attributed to the glutathione redox cycle and the conversion of reduced riboflavin to its oxidized form [38]. Values of cell viability greater than 100% are not rare and could be understood because the XTT assay actually measure metabolic activity when reducing the tetrazole to formazan. It is usually assumed that conversion is dependent on the number of viable cells, but it could also be related to an expected increased enzymatic activity when cells are exposed to small doses of some new substance. Further analysis showed that this effect was not the only one responsible for better cell viability of vitaminB@P25TiO2NPs treated samples.
