Effect of dopants on the phase formation in microwave processed Al–Al2O3 composites

Microwave processing of undoped and doped Al powder compacts was performed for the preparation of Al?Al2O3 composites. Mg, Mg?Si and Al2O3 were used as dopants to study their effects on the oxidation of Al powder and resultant Al?Al2O3 composites.

Overview of the practically important behaviors of zeolite-based urea-SCR catalysts, using compact experimental protocol

Selective catalytic reduction with NH3 (NH3-SCR technology), based on V2O5/WO3/TiO2 catalysts, has been previously commercialized for abating NOx emissions from various stationary and mobile lean-burn or diesel engines.

Pyrite accumulation in salt marshes in the Eastern Scheldt, southwest Netherlands

AbstractPore water composition, pyrite distribution and pyrite crystal morphology of sediments from salt marshes in the Eastern Scheldt, southwestern Netherlands, were examined from July 1984 to October 1986.Hydrology and marsh vegetation were the chief determinants of pyrite accumulation.

Heterogeneous catalytic wet peroxide oxidation of paraquat in the presence of modified activated carbon

The catalytic wet peroxide oxidation (CWPO) method was applied to the degradation of paraquat, a widely used and highly toxic herbicide. The effect of ammonia pre-treatment and iron impregnation on Fenton-driven reaction efficiency was first investigated.

Influence of textural parameters on the catalytic behavior for CO oxidation over ordered mesoporous Co3O4

Ordered mesoporous Co3O4 has been synthesized by nanocasting from three-dimensional cubic KIT-6 template. The cobalt precursor is introduced into the silica pores by the ?bi-solvent? method.

Effect of manganese and calcium ions on the photoinduced water oxidation with photosynthesis organ grana from green plant

To develop the visible light-induced hydrogen and oxygen production based on the water photolysis, 2,6-dichloroindophenol (DCIP) reduction based on the photoinduced water oxidation with oxygen evolved centre (OEC) of PSII in photosynthesis organ, grana from spinach was studied.

The interaction of Zr2Fe surface with O2 and H2O at the temperature range 300–770K

The surface of metallic Zr2Fe was exposed to oxygen and water vapor, in order to study the effects of these gases, being the main degradation agents in its operation as a getter for hydrogen.

Delamination and Adhesive Wear Behavior of α-Tocopherol–Stabilized Irradiated Ultrahigh-Molecular-Weight Polyethylene

Wear and delamination of conventional ultrahigh-molecular-weight polyethylene (UHMWPE) components used in total knee arthroplasty can compromise long-term performance. Radiation cross-linking and melt-annealing reduced wear and increased delamination resistance of UHMWPE.

Mechanical Properties, Oxidation, and Clinical Performance of Retrieved Highly Cross-Linked Crossfire Liners After Intermediate-Term Implantation

Sixty Crossfire (Stryker Orthopaedics, Mahwah, NJ) liners were consecutively revised after an average of 2.9 years (range, 0.01-8.0 years) for reasons unrelated to wear or mechanical performance of the polyethylene.
