“…However, it is not clear why the Nd 2 Ni 0.8 Cu 0.2 O 4+δ sample have higher conductivity than other two samples. Small amount of copper doping can increase the mean valence of nickel and copper in the Nd 2 Ni 0.8 Cu 0.2 O 4+δ sample [22].…”

Mixed ionic and electronic conducting K2NiF4-type oxide, Nd2Ni1-xCuxO4+δ (x=0~1) powders were synthesized by solid state reaction technique and solid oxide fuel cells consisting of a Nd2Ni1-xCuxO4+δ cathode, a Ni-YSZ anode and ScSZ as an electrolyte were fabricated. The effect of copper substitution for nickel on the electrical and electrochemical properties was examined. Small amount of copper doping (x=0.2) resulted in the increased electrical conductivity and decreased polarization resistance. It appears that this phenomenon was associated with the high mean valence of nickel and copper and the resulting excess oxygen (δ). It was found that power densities of the cell with the Nd2Ni1-xCuxO4+δ (x=0.1 and 0.2) cathode were higher than that of the cell with the Nd2NiO4+δ cathode.

“…It appears that there are two opposed effect of the copper addition on the catalytic activity of the Nd 2 NiO 4+δ oxygen ion conductivity increases with increasing copper content, while electrical conductivity increases with decreasing copper content. Thus, adding small amount of copper is the trade-off in two properties and as a consequence, the cathode sample with x=0.05 exhibited the lowest ASR value [26,27]. Fig.…”

In this study, Nd2Ni1-xCuxO4+δ (x=0, 0.05, 0.1, and 0.2) layered perovskite powders were synthesized by the glycine nitrate process (GNP) and the chromium poisoning effect on the electrochemical performance of the Nd2Ni0.95Cu0.05O4+δ and La0.6Sr0.4Co0.2Fe0.8O3-δ cathodes were investigated. In the case of the LSCF cathode, the strontium chromite phase formed after the exposure of the gaseous chromium species, while there was no additional phase in the Nd2Ni0.95Cu0.05O4+δ cathode. The area specific resistance (ASR) of the Nd2Ni0.95Cu0.05O4+δ cathode did not change significantly after the exposure of the gaseous chromium species at 800°C.

“…60 Increased oxidative stress can cause inflammation through the activation of the nuclear factor kappalight-chain-enhancer of activated B cells (NF-kB) transcription factor, and inflammation contributes to several neurologic diseases, such as Alzheimer's disease and Parkinson's disease. 78 MeHg has been shown to increase IL-6 release from glial cells 79 and activation of NF-kB has been observed in rat cerebrum and cerebellum. 80 Changes in gene expression can be more severe if the exposure occurs during neurodevelopment.…”

The neurotoxic consequences of methylmercury (MeHg) exposure have long been known, however a complete understanding of the mechanisms underlying this toxicity is elusive. Recent epidemiological and experimental studies have provided many mechanistic insights, particularly into the contribution of genetic and environmental factors that interact with MeHg to modify toxicity. This review will outline cellular processes directly and indirectly affected by MeHg, including oxidative stress, cellular signaling and gene expression, and discuss genetic, environmental and nutritional factors capable of modifying MeHg toxicity.
