In order to develop low-temperature (below 200 °C) and SO2-tolerant catalysts for selective catalytic reduction (SCR) of NOx, a series of cheap M/bauxite (M = Mn, Ni and Cu) catalysts were prepared using bauxite as a support. Their SCR performances are much superior to typical V2O5/TiO2, the addition of M into bauxite results in significant promotion of NOx removal efficiency, especially at low...

Control of Ag electro chemical migration is crucial for long–term reliability electrical components in high–voltage applications. In this work, Cu was bonded onto an AlN substrate at temperatures between 650 °C and 950 1 h using a free Cu–P–Sn–Ni brazing filler metal with Ti as active addition. The interfacial structure the mechanical properties bond were both investigated. Three different phas...

The current work focuses on working a comparison between two solar cells made with the combination, n-TiO2/p-CuO, and n-TiO2/p-Cu2O devices. structural, optical, photovoltaic characteristics were detailed. In optical section, measurements for TiO2 (120 nm), CuO (200 Cu2O nm) thin films illustrated, then energy of transition was calculated based Tauc formula each layer. direct gap energies TiO2,...

The use of nanofluids for heat transfer has been examined in recent years as a potential method augmentation different systems. Often, the nanoparticles working fluid does not disrupt system significant ways. As result this general improvement system’s capabilities with relatively few detrimental factors, and hybrid have become an area considerable research interest. One subcategory that under ...
