Characteristics, Thermodynamics, and Preparation of Nanocaged 12CaO·7Al2O3 and Its Derivatives

“…26 Despite the fact that some characteristics of C12A7 being reviewed recently by Kim et al 28,29 with focus on fabrication and properties of fantastic C12A7-e À electride, plus a few derivatives, and partial phase diagram of relevance, it is far away from completion to provide a whole picture of material database. Referring to phase diagram, constant effort has been put on generating thermodynamic data of C12A7 phase since 1900s, [1][2][3][4][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] but uncertainty still remains for newly published data. 46,48,49 As compositions (ratios of raw materials or/ and additions) and fabrication processing (sintering time, atmosphere, and temperature) 27,[50][51][52] have great effects on resulting performances and characteristic properties of oxides, the synthesis methods for multifunctional C12A7 single crystal are still under debated.…”

“…26 Phase diagram of CaO-Al 2 O 3 system (shortened as C-A with C=CaO and A=Al 2 O 3 ) has been studied many times since 1900s. 1,[31][32][33][34][35][36][37][38]41,44,[64][65][66][67][68][69][70][71] The first knew phase diagram of C-A system was proposed by Rankin and Wright in 1909 1,64 whereas four binary compounds including C3A, C5A3, CA, and C3A5 being reported and confirmed later by Tavasci in 1937, 31 Filonenko and Lavrov in 1949, 32 and Wisnyi in 1954 33 (see Fig. 3a here, listed in AcerS Phase Diagrams for Ceramists as figure 00233, with high-alumina portion).…”

Teaching Sustainability: From Monism and Pluralism to Citizenship

“…The focus on land has significant pedagogical advantages. One of them is what has been called ‘teaching with historical perspectives’ (Tavasci & Ventimiglia, 2018). Not only does historical contextualization provide a sense of the continuing importance of land, but it also helps with resolving questions about causation and promoting transdisciplinarity (Fuller, 2018; Obeng-Odoom, 2017).…”
