The synthetic anhydrous crystalline CaCO 3 polymorphs—vaterite, aragonite and calcite—
were tested using dilatometry and nanoindentation. Microstructural changes in the samples …

A hitherto unknown composition is highlighted in the red and black inks preserved on
ancient Egyptian papyri from the Roman period (circa 100 to 200 CE). Synchrotron-based …

Conditions for the synthesis of vaterite without additives have been investigated (T= 30–90°
C, stirring velocity= 200–600 rpm). The obtained different CaCO 3 polymorphs were …

Wood ash found at archaeological sites is the most direct evidence of the presence of
combustion features. The preservation of wood ash within archaeological deposits is often …

Lime mortars have played an important role in constructing ancient Chinese masonry
structures, including city walls, buildings, and tombs. A tomb built with lime mortars and …

In the present work, a multi-analytical approach was used to analyze samples collected from
the wall paintings of Qasr el-Ghuieta temple, Kharga Oasis, Egypt. The temple is dating back …

This review demonstrates advances in XRF instrumentation, techniques and data
