Ni-Substituted SrFeMoO as an Electrode Material for Symmetrical and Reversible Solid-Oxide Cells.

This work develops a novel perovskite SrFeNiMoO (SFNM) simultaneously using as a fuel electrode and oxygen electrode in a reversible solid oxide cell (RSOC). SFNM shows outstanding electrocatalytic activity for hydrogen oxidation, hydrogen evolution, oxygen reduction, and oxygen evolution. In situ exsolution and dissolution of Fe-Ni alloy nanoparticles in SFNM is revealed.

B-Site Super-Excess Design SrVFeMoO-Ni as a Highly Active and Redox-Stable Solid Oxide Fuel Cell Anode.

In-situ exsolution type perovskites as solid oxide fuel cell (SOFCs) anode materials have received widespread attention because of their excellent catalytic activity. In this study, excessive NiO is introduced to the SrVFeMoO (SVFMO) perovskite with the B-site excess design, and in-situ growth of FeNi alloy nanoparticles is induced in the reducing atmosphere to form the SrVFeMoO-Ni (SVFMO-Ni) composite anode. Here, with H or CH as SOFCs fuel gas, the formation of FeNi nanoparticles further enhances the catalytic ability.

Quantification of Structural Defects Using Pixel Level Spatial Information from Photogrammetry.

Aging infrastructure has drawn increased attention globally, as its collapse would be destructive economically and socially. Precise quantification of minor defects is essential for identifying issues before structural failure occurs. Most studies measured the dimension of defects at image level, ignoring the third-dimensional information available from close-range photogrammetry.

In vivo study of effects of artesunate nanoliposomes on human hepatocellular carcinoma xenografts in nude mice.

To investigate the effect of artesunate nanoliposomes on cultured cells in vitro and hepatocellular carcinoma xenografts in BALB/c-nu mice. Fluorescence polarization was applied for measurement of mitochondrial membrane fluidities; inhibition test of tumor cell proliferation in vitro was performed and nude mice xenograft model from human hepatocellular carcinoma (HCC) was established. Cytotoxicity of these compounds was evaluated by MTT assay on hepatocellular carcinoma xenografts in nude mice.

Effects of artemisinin derivative on the growth metabolism of Tetrahymena thermophila BF5 based on expression of thermokinetics.

The toxic effects of artesunate and dihydroartemisinin on the growth metabolism of Tetrahymena thermophila BF5 were studied by microcalorimetry. The results showed that: (1) low concentrations of artesunate ( View Article and Find Full Text PDF
