Abstract Real-time stress sensing based on mechanoluminescence materials has been widely studied for structural health monitoring of bridges, buildings, high-pressure vessels, and other infrastructure surfaces. However, this approach is difficult to detect the information closed mechanical structures. Here, we propose a delayed memory strategy record structure by flexible film composed with CaA...

The reaction pathway for the Ca3Al2O6 formation up to 1300 C; from mechanochemically treated mixtures of amorphous aluminum hydroxide and CaCO3; was studied in situ by differential thermal analysis, constant heating rate dilatometry and timeresolved neutron powder diffraction. The experiment was carried out, in an open system, on a sample with the nominal Ca3Al2O6 stoichiometry. The results obt...

Alkaline earth aluminates with the overall nominal compositions Mg0.5Sr0.5Al2O4 (MSA), Ca0.5Sr0.5Al2O4 (CSA) and Ca0.5Mg0.5Al2O4 (CMA) doped with 0.5 or 1 mol% of Eu2+ ions were obtained by a modified aqueous sol-gel method and annealed in a reductive atmosphere at 900, 1000, 1100 and 1300 °C. The sample compositions and their structures were studied by XRD employing the Rietveld method. Solid ...
