Superfill (bottom-up) phenomena relevant for Damascene processing typically rely on the time-dependent interplay of various organic and inorganic additives with both the metallic copper surface and with cuprous ions as intermediates of the copper electro-reduction in the near-surface regime. In-situ STM, in-situ SXRD (Surface X-Ray Diffraction) measurements combined with DFT calculations provide new...
The selective catalytic reduction (SCR) reaction belongs to the gas-solid multiphase reaction, and the adsorption of NH3 and NO play an important role in the reaction. The adsorption behaviors of NH3 and NO were studied with the diffuse reflectance infrared transform spectroscopy (DRIFTS) methods; these results showed that there were obvious adsorption phenomena of NH3 and NO on the catalysts. NH3...
In this study, nitrate reduction using laboratory synthesized nanoscale zero-valent iron (NZVI) was discussed. On the other side, denitrification of nitrate with Fe0 nanoparticles combined with zeolite was also investigated. The effects of iron-to-nitrate ratio and the affiliation of zeolite were studied systemically. The results show that nitrate with the concentration of 80 mg/L was mostly removed...
