We theoretically predict and numerically simulate the discrete plasmonic Talbot effect in dielectric graphene plasmonic waveguide (DGPW) arrays at THz wavelengths. The super-modes in DGPW arrays are analyzed by using super-mode theory and the field intensity distributions in the designed DGPW arrays are explained by the superposition of different super-modes and simulated by using commercial software...
A series of activated carbon (AC) supported nickel oxide (NiO) catalysts were prepared by aqueous reduction preparation methods with nickel nitrate as a precursor. The effects of preparation procedure and reducing agent on catalyst structure and catalytic property were investigated. Based on the information obtained from physico-chemical characterizations and sorbitol dehydration performances, preparation...
Multi-walled carbon nanotube–tungsten carbide composites were prepared by the reduction and carbonization process using multi-walled carbon nanotubes (MWCNTs) and WO 3 precursor by molecular level mixing and calcination. The pre-prepared MWCNT–tungsten carbide composites were characterized by scanning electron microscope and transmission electron microscope. Furthermore, the crystal phase...
