Methane oxy-steam reforming over a highly efficient Ni/Al2O3 nanocatalyst prepared by microwave-assisted impregnation method

An alumina-supported nickel catalyst was prepared by impregnation of Ni2+ solution onto mesoporous alumina under microwave irradiation (denoted as M-Ni/Al2O3). For comparison, a catalyst with the same nickel content was prepared by conventional impregnation method (denoted as UM-Ni/Al2O3). Both M-Ni/Al2O3 and UM-Ni/Al2O3 catalysts were applied to the syngas (H2 + CO) production by methane oxy-s...

Microwave Absorption and Infrared Stealth Characteristics of Bamboo Charcoal/Silver Composites Prepared by Chemical Reduction Method

Bamboo charcoal coated with silver (BC/Ag) was prepared by activation and chemical reduction processes at different AgNO3 contents (10-30 wt.%). The spectroscopic characterizations of the formation processes of BC/Ag composites were studied using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. These composites were introduced in epoxy resin to be a microwav...

Excellent Field Emission Properties of Short Conical Carbon Nanotubes Prepared by Microwave Plasma Enhanced CVD Process

Randomly oriented short and low density conical carbon nanotubes (CNTs) were prepared on Si substrates by tubular microwave plasma enhanced chemical vapor deposition process at relatively low temperature (350–550 C) by judiciously controlling the microwave power and growth time in C2H2 + NH3 gas composition and Fe catalyst. Both length as well as density of the CNTs increased with increasing mi...

Characteristics of Acoustic Emission Signals from Composites

Certain characteristics of acoustic emission (AE) signals from graphite-epoxy composite specimens were correlated last year with the mechanical behavior of the materials. Moisture degradation, which reduced the ultimate strength, resulted in a change in the AE amplitude distribution early in the loading history. Also, AE having distinct frequency spectral types tended to occur at or near singul...

Microwave-Assisted Sintering of Al–ZrO2 Nano-Composites

Abstract In this project, nano-ZrO2 particles were dispersed in aluminum powder by a Y-shape mixer. The particle size of ZrO2 powder was < 40 nm and the amount of ZrO2 reinforcement varies from 3 to 15%.The mixed powders were compacted .Subsequently the compacted discs were sintered both in the microwave oven and in the conventional muffle furnace .Using microwave –assisted sintering method led...
