“…The splendid civilization of the Chinese nation has left behind many stone cultural relics that attract worldwide attention, such as the grottoes, stone carvings, steles, statues, and various buildings of the past dynasties. The stone cultural relics have important historical and cultural significance and research value [1][2][3][4]. As one of the ancient stone building materials, the stone tiles have been developed more than three thousand years.…”

The Song Dynasty stone tiles are one of the representatives of ancient Chinese building materials and reflect the technical level and the aesthetic concept of architecture in the Song Dynasty. Studying the mechanical properties of the Song Dynasty stone tiles is a great significance to design and develop restoration materials. The stone cultural relics are different from modern buildings, because of their particularity, cultural relics protection should preserve their original historical features as much as possible. It is a challenge to sample and perform traditional tests, which require numerous large specimens. The nanoindentation technique and the homogenization calculation method based on the Mori-Tanaka model were proposed to calculate the mechanical parameters of the Song Dynasty stone tiles. With the help of X-ray diffraction (XRD) and scanning electron microscope (SEM), the indentation morphology and mineral composition in indentation area were quantitatively analyzed. The mechanical properties, such as elastic modulus, hardness and fracture toughness of the Song Dynasty stone tiles in Henan, China, were investigated by nanoindentation test. The homogenization approach based on the Mori-Tanaka model was developed to upscale mechanical parameters from micro-scale to meso-scale, which were further compared with uniaxial compression results of non-standard samples. The results show that there is a positive linear correlation between elastic modulus, hardness and the fracture toughness under micro-scale. The average elastic modulus of red stone tiles and green stone tiles are 29.47GPa and 30.21GPa respectively. Compared with the parameter results obtained by upscaling, the deviation rates are 10.3% and 9.6%, respectively. The mechanical parameters of the Song Dynasty stone tiles obtained by nanoindentation test and homogenization approach is reliable.The proposed methods in this work provide the basis and reference for obtaining the mechanical strength index of the Song Dynasty stone tiles.

“…

Water vapor barrier coatings with the ability to prevent water vapor molecules passing through coatings or decrease the transmission rate of water vapor molecules can be applied in various fields, such as food packaging, [1,2] encapsulation of electronic devices, [3,4] cultural relic's protection, [5,6] anticorrosion of metals, [7,8] optical crystal moistureproof, [9,10] and so on. As one of the most important components in high power laser system, potassium dihydrogen phosphate (KDP) crystal is water-soluble which is more susceptible to moisture deliquescence.

Developing siloxane‐based coatings with excellent water vapor barrier ability is of great importance due to their wide applications for various optical‐related fields. To improve the water vapor barrier ability of polysilsesquioxane coatings, this research proposes a strategy of introducing carbon quantum dots (CQDs) into organic‐bridged polysilsesquioxane coatings to enhance their water vapor barrier property. The CQDs are prepared by the pyrolysis of citric acid and then the composite coatings are prepared by thioether‐ester‐bridged silsesquioxane precursor in situ hydrolysis and condensation in the presence of CQDs. The experimental results show that the CQDs disperse well in the polysilsesquioxane matrix which is conducive to provide long diffusion pathway of water vapor molecules and also introduce individual “bubble pores” into the composite coatings. Thus‐obtained composite coatings not only show fivefold enhancement in water vapor barrier ability compared to the polysilsesquioxane coating without CQDs, but also perform good light transparence and good UV radiation‐resistant property, which would satisfy the requirements of optical‐related moisture‐resistant application fields.
