“…Chemical characterization of the carotenoid extract identified major components as C50 carotenoids, probably decaprenoxanthin and/or sarcinaxanthin. Scanning electron microscopy revealed minimal surface changes in bacteria during carotenoid-rich phase after UV-B irradiation exposure.These findings highlight the likely ability of LAPM80 strain's C50 carotenoids to improve UV-B iiradiation resistance, indicating their potential for developing natural photoprotective compounds for the dermo-cosmetic industry.…”

How mechanochemistry affects the composition and properties of disordered fluorite BaSnF4? by Mercadier, Briséïs, Legein, Christophe, Duttine, Mathieu, Body, Monique, Gutierrez, Ana Gabriela Porras, Leclerc, Sandrine, Lebedev, Oleg,  Masquelier, Christian, Dambournet, Damien

“…Microstructural analysis obtained by X-ray line refinement and Williamson–Hall diagrams showed that increasing the ball milling time resulted in a decrease in particle size from 13 to 6 nm and suppressed the occurrence of microstrains, which were identified as twinned regions by microscopy analysis. Prolongation of the ball milling treatment is also associated with a decrease in ionic conductivity with identical fluoride ion jump activation energy. 119Sn Mössbauer spectroscopy revealed the presence of a new signature assigned to Sn(IV) in an oxide–fluoride environment. …”
