Sustained income reductions during economic recession predict depression onset in people with chronic illnesses: A 6-month prospective study

The polycrystalline Sm and Mn co-substituted bismuth ferrites Bi1-xSmxFe0.95Mn0.05O3 (x = 0.08 and 0.16) with composition near the morphotropic phase boundary have been prepared using a modified solid-state reaction method. The Bi0.92Sm0.08Fe0.95Mn0.05O3 ceramic possesses single rhombohedral phase, whereas the Bi0.84Sm0.16Fe0.95Mn0.05O3 ceramic consists of both the R3c and Pnma phases. The addition of Sm and Mn not only enhances density and...
