TL;DR: In this paper, two cast nickel-base superalloys with superior creep rupture life at high temperatures and high stresses were developed and the microstructural characteristics of γ-precipitates and the hardening behavior were studied by electron microscopy and micro-hardness testing.

TL;DR: In this paper, a fabric-based wearable piezoelectric energy harvester (fabric-WPEH) is demonstrated, which has a heterostructure of a ferroelectric polymer, poly(vinylidene fluoride-co-trifluoroethylene) and two conductive fabrics via simple fabrication of tape casting and hot pressing.

TL;DR: The M3I3 initiative aims to reduce the time for the discovery, design and development of materials based on elucidating multiscale processing-structure-property relationship and materials hierarchy, which are to be quantified and understood through a combination of machine learning and scientific insights as discussed by the authors.

TL;DR: It is found that locally connected ordering defects decreased with increasing distilled water concentration and the optimum conditions of well-ordered hexagonal pore arrangement were 2 and 10 vol% distilled water with 0.2 and 0.4 wt% NH4F, respectively.

TL;DR: In this paper, LiNbO3 or LiVO3, which is formed by NbO5 or V2O5, causes an increase in oxygen activity of the lithium ferrite and a decrease in the rate of lithium evaporation during sintering.
