The nickel-based superalloy 718 after processing through three thermomechanical routes, i.e., forged, hot rolled, and cold was investigated considering its δ-phase (Ni3Nb–DOa) intergranular precipitation. samples were subjected to different combinations of annealing aging heat treatments obtain grain boundary character distribution (GBCD) as well volume fractions morphologies. While precipitation can be beneficial avoid growth during recrystallization, an increase in fraction detrimental...
Nanocomposite generators convert mechanical energy into electrical and are attractive low-power solutions for self-powered sensors wearables. Homogeneous dispersion, high concentration, orientation of the embedded filler strategies have been assumed to maximize voltage output in nanocomposite generators. This work contrast these assumptions by studying dominance interphase low concentrations (¡10%) random dispersions a ZnO/PDMS generator with peak-to-peak generation capabilities (≈150 V)....

Abstract This manuscript reports room-temperature one-step synthesis of earth-abundant semiconductor ZnSiN 2 on amorphous carbon substrates using radio frequency reactive magnetron co-sputtering. Transmission Electron Microscopy and Rutherford Backscattering Spectrometry analysis demonstrated that the has occurred as nanocrystals in orthorhombic phase, uniformly distributed carbon. The technique large-area deposition an substrate can be interesting for flexible electronics technologies. Our...
