Abstract

Rice which is one of the largest agriculture crops produces around 22% of rice husk during its milling process. This material is mainly used as fuel for energy generation, resulting in an ash, which disposal represents an environmental issue. The rice husk ash (RHA) contains over than 70% of silica in an amorphous form and a lot of applications is being developed for it all over the world. The use of silica as a filler in the tire industry is growing since it contributes significantly to the reduction of fuel consumption of the automobiles, allowing at the same time better traction (safety). This paper presents an evaluation of the use of RHA as filler in rubber tread compounds prepared in lab scale and compares its performance with compounds prepared with commercial silica and carbon black, the filler normally used in tire industry. Mechanical and rheological properties are evaluated, with emphasis for tan delta as an indicator of thread performance related with rolling resistance (fuel consumption) and wet grip/traction (safety).

23. Spectroscopy of small diameter single-wall carbon nanotubes.

Author

Jorio, A., Fantini, C., Cançado, L. G., Ribeiro, H. B., Santos, A. P., Furtado, C. A., Dresselhaus, M. S., Dresselhaus, G., Samsonidze, Ge. G., Chou, S. G., Grueneis, A., Jiang, J., Kobayashi, N., Saito, R., and Pimenta, M. A.

Abstract

Resonance Raman spectroscopy of small diameter (below 1.2 nm) single-wall carbon nanotubes (SWCNT) is presented. The diameter and chirality dependent many-body corrections to the tight binding based Kataura plot are discussed. The radial breathing modes also show small chirality dependence, giving evidence for the deviations of the small nanotube diameters from the ideal folded graphene structure. The use of spectroscopy for the characterization of small environmental effects and the (n,m) population on HiPco and CoMoCAT SWNT samples is pointed out. The richness of the intermediate frequency modes is highlighted. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
