Carbon Supported Cu and TiO2 Catalysts Applied for Ozone Decomposition

In this article a comparison was made between Cu and TiO2 supported catalysts on activated carbon for ozone decomposition reaction. The activated carbon support in the case of TiO2/AC sample was prepared by physicochemical pyrolysis and for Cu/AC samples the supports are chemically modified carbons. The prepared catalysts were synthesized by impregnation method. The samples were annealed in two...

Multiwall Carbon Nanotube Reinforcement of Polyacrylonitrile Fibers

Aligning multiwall carbon nanotubes (MWNTs) with the direction of load is desirable for maximizing tensile reinforcement in composites. This has been accomplished by spinning composite fibers containing MWNTs[1]. The shear and elongational flow fields inherent to fiber processing cause the MWNTs to align with the fiber axis. Efficient stress transfer from the matrix to the MWNTs is also a cruci...

Photonics with multiwall carbon nanotube arrays.

We investigate the photonic properties of two-dimensional nanotube arrays for photon energies up to 40 eV and unveil the physics of two distinct applications: deep-UV photonic crystals and total visible absorbers. We find three main regimes: for small intertube spacing of 20-30 nm, we obtain strong Bragg scattering and photonic band gaps in the deep-UV range of 25 approximately 35 eV. For inter...
