Effect of the addition of Y and Y2O3 on microstructure and mechanical properties of 15Cr-15Ni ODS steel

Nuclear Materials and Energy, 2022
15Cr-15Ni ODS steels with the addition of Y or Y2O3 were fabricated via the mechanical alloying and hot isostatic pressing, followed by forging treatment (named as 15Cr-15Ni-Y and 15Cr-15Ni-Y2O3, respectively). The morphology of as-milled powders of 15Cr-

Manipulating Atomic Disorder and Mesoscale Architectures for High‐Efficiency Thermoelectric Modules

Advanced Science, EarlyView.
The in situ reaction of PbTiO3 precursor reacts in situ with the Bi0.5Sb1.5Te3 matrix, effectively enlarging the energy barrier for minority carrier excitation and suppressing bipolar diffusion, and predominantly scattering mid‐to‐low frequency phonons. Ultimately, a single thermoelectric module was fabricated to achieve a competitive efficiency of ∼7%
