The existence of oxidation embrittlement in previously developed ceramic‐matrix composite (CMC) systems at intermediate temperatures (500–900°C) has motivated the development of all‐oxide CMCs. Studies of the damage tolerance of an all‐oxide CMC suggest that it relies on distributing fiber bundles heterogeneously in a…

Experiments with the continuous precipitation of calcium carbonate are reported in this study. Particle size distributions were measured on-line and interpreted by means of the simultaneous nucleation and the transformation models developed in part 1 of this sequence. Three regimes of precipitation are reported in thi…

Electromigration occurs along grain boundaries in polycrystalline thin-film conductors when the grain size is significantly larger than the conductor width. As circuit feature sizes have been reduced, microstructures have become near bamboo and alternate diffusion mechanisms must operate within the bamboo grains. In t…

The paper presents the results of an investigation on the electrical performance of artificially contaminated non-ceramic insulators as a function of resting time. Resting time is defined as the time interval between the application of contamination and start of testing. New (unaged), full scale, 69 kV non-ceramic ins…

The electrochemical behavior of the 2,2‘-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), a reversible redox probe, has been examined after it has been intercalated into the interlayer spacing of anionic clays (also called layered double hydroxides, LDH). The cyclic voltammetry response of [Zn-Cr-ABTS] and [Zn-Al-…

Qualitative ab initio theory is used to compare the electronic structures of nickel dithiolate complexes and the monosulfinates arising from O2 oxidations. The results are used to examine the electronic factors involved in the reaction mechanism. The frontier molecular orbitals (FMOs) of the dithiolate complexes are d…

Recent studies have suggested that hydride precipitation at the metal/oxide interface could play a detrimental role on the waterside corrosion rate. Nevertheless, the mechanism of that detrimental role is not completely understood, and two hypotheses were investigated to understand the mechanism that controls the role…
