Barium, zinc and strontium yellows in late 19th–early 20th century oil paintings
Heritage Science, 2017 This work focuses on the study of the 19th century yellow chromate pigments based on barium (BaCrO4), zinc (4ZnCrO4·K2O·3H2O) and strontium (SrCrO4). These pigments, which are reported to shift in hue and darken, have been found in 19th century artworks.

Surface and Interface Analysis, Volume 58, Issue 1, Page 28-34, January 2026.ABSTRACT This study demonstrates how a hydroxyapatite/(HaP) structure influences and determines cell viability/proliferation on electrospun hybrid polycaprolactone/sodium‐alginate/collagen scaffolds when mesenchymal cells are seeded. Four different HaPs were tested: (1) nanometric/(nHaP), (2) micrometric/(μHap), (3) functionalized/(nHaPf), and (4 ...
