Per- and polyfluoroalkyl substances (PFAS) are considered to be forever chemicals. Many are toxic; others are highly mobile or accumulate in the food chain. However, all are extremely persistent a .
Researchers at the Department of Analytical Chemistry, at the University of the Basque Country, employed a Linkam THMS600 in the study of the phase transition of plattnerite [ß-PbO2 lead (IV) oxide]-based historical painting.
UrFU chemists have developed a sensor that can determine the pH level of human saliva. This is a fluorophore with a strong and steady emission that detects even minor pH changes in biological fluids (tenths). Micro doses of the chemical are used in the analysis, as well as a spectrometer in which the substance is irradiated with a specific light (its lifetime is tens of thousands of hours). In 5–7 seconds, the pH data emerges.
