The sustainability of social media is a common subject of study. With the emergence of cultural and creative industries, many studies have begun to explore the advantages and disadvantages of the integration of social media with cultural and creative industries. However, there remains a lack of research on the sustainability of cultural and creative social media. Therefore, the present study uses the example of a non-profit cultural and creative organization as its case. The use of social media content discovery technology explains the sustainable use of cultural and creative social media and how participation and interaction with cultural and creative brands are promoted from the perspective of artists or ordinary people. In addition, the analysis of concrete and abstract information explores how content orientation and brand perception impact emotions and behavior. We use social media content discovery technology to analyze 9529 image posts. The results show that for abstract themes, for example, art or design, people can be more easily guided by information with the help of images, which stimulate positive emotions, resulting in more actual engagement behavior, including posting and sharing. With respect to emotional responses, images with smiles are found to have a significant effect in guiding positive emotions, which are expressed through actions, such as active participation and feedback. By examining the meaning of the information in the images, we find that images with abstract themes have a good connection with the brand image. Although the information is less easily shown, it can guide significant outcomes that are positively correlated with the information. Therefore, strengthening brand image and content themes can effectively consolidate trust in brand content and the sustainable development of cultural and creative social media.

Bi 4 Ti 3 O 12 high-temperature piezoelectric ceramics composed of 0.03 mol (Nb, Ta) 5+ substituting B site and x mol CeO 2 (x = 0-0.05, abbreviated as BCTNT100x) substituting A site were synthesized by the conventional solid-state reaction method. The effects of Ce additive on the structures and electrical properties of resulting Bi 4 Ti 3 O 12 -based ceramics were systematically investigated. In-situ temperature-dependent X-ray diffraction (XRD) confirmed that the phase structure of BCTNT100x ceramics change from orthorhombic structure to tetragonal structure as temperature increased. The ceramics at Ce content x = 0.03 illustrated optimal performances with superior piezoelectric constant (d 33 = 36.5 pC/N), high Curie temperature (T C = 649 • C), and large remanent polarization (2P r = 21.6 μC/cm 2 ). BCTNT3 ceramics also possessed high d 33 of 32.5 pC/N at an annealing temperature of 600 • C, with electrical resistivity preserved at 10 6 Ω cm at 500 • C. These results demonstrate that BCTNT100x ceramics can be used as high-temperature piezoelectric devices.

The molten-salt method was used to synthesize CaBi 2 Ta 2 O 9 (CBTa) powder, and the influence of temperature on the structure and micromorphology of products was investigated using X-ray diffraction and the scanning and transmission electron microscope. The results showed that highly crystalline CBTa nanoplates exhibit single orthorhombic symmetry and could be obtained in the temperature range of 850-900°C. Among which, the nanoplates prepared at 900°C have optimal properties (average grain size of 1.7 μm and uniform size distribution). Above 900°C, various CaO-Ta 2 O 5 binary compounds, Bi 2 O 3, and BiTaO 4 formed due to the decomposition of CBTa and subsequent reactions of decomposition products, transforming plate-like grains to cuboid nano-particles with a small amount of prismatic grains. Possible reaction mechanisms at different synthesizing temperature were proposed. This work provides a method for the preparation of template grains to synthesize textured CaBi 2 Ta 2 O 9 high-temperature piezoelectric ceramics by the template grain growth method.
