This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists' pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

Market demand is another critical factor that influences the anatase price. As more industries recognize the potential of anatase in improving their products' performance and efficiency, the demand for this compound is expected to rise As more industries recognize the potential of anatase in improving their products' performance and efficiency, the demand for this compound is expected to rise As more industries recognize the potential of anatase in improving their products' performance and efficiency, the demand for this compound is expected to rise As more industries recognize the potential of anatase in improving their products' performance and efficiency, the demand for this compound is expected to riseanatase price. For instance, the growing need for eco-friendly solutions in the construction industry has led to an increased demand for anatase-based photocatalytic coatings that can help reduce air pollution. Similarly, the development of new technologies like perovskite solar cells has opened up new opportunities for anatase, further driving up its demand and price.

For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.
