To prepare thermally stable and high-performance polymeric films, new solvent-soluble aromatic polyamides with a carbamoyl pendant group, namely poly(4,4Јdiamino-3Ј-carbamoylbenzanilide terephthalamide) (p-PDCBTA) and poly(4,4Ј-diamino-3Ј-carbamoylbenzanilide isophthalamide) (m-PDCBTA), were synthes
The synthesis, structure, and physical properties of \(\mathrm{La}_{3-x}\) \(M_{x} \mathrm{Ni}_{2} \mathrm{O}_{7-\delta}\), with \(M=\mathrm{Ca}^{2+}, \mathrm{Sr}^{2+}\), or \(\mathrm{Ba}^{2+}\), and \(0<x \leq 0.075\), were investigated. These compounds were prepared by a precursor method with tetr
