Solubility in supercritical carbon dioxide
… solubility of compounds in supercritical carbon dioxide are described. A comparative study is made of the methods used in the measurement of the concentration of benzoic acid and caffeine in supercritical carbon dioxide. The difference in measurement techniques did not have much effect on the …

Absorption of Dietary Titanium Dioxide
Food grade Titanium dioxide (fgTiO2) is used as a colouring additive in the food industry, and it is present in food, capsules, and toothpaste. We are exposed to a median of 2.5 mg fgTiO2 per day in the UK through such sources. These are persistent micro and nanoparticles that have been reported in …
