This paper studied the electrical resistivity and piezoresistivity of specimen of cement paste made with multiwall carbon nanotubes (MWNTs). The twelve sodium dodecyl benzene sulfonate (SDBS) was used as surfactant. Specimen had a MWNTs to SDBS ratio of 1/4 and contained 0.2% NWNTs by weight. Different dispersal durations, 15min, 30min, 45min, were adopted. The test results show that under the same period of curing, when the dispersal time of MWNTs was 45min, the electrical resistivity of the composite was the biggest and the curve was the varied;with the age growth, the electrical resistivity increased obviously;with the increase of moisture content, the resistivity decreased significantly.

Abstract Background Predatory flagellates and ciliates are two common bio-contaminants which frequently cause biomass losses in Chlorella mass culture. Efficient and targeted ways are required to control these contaminations in Chlorella mass cultivation aiming for biofuel production especially. Results Five surfactants were tested for its ability to control bio-contaminations in Chlorella culture. All five surfactants were able to eliminate the contaminants at a proper concentration. Particularly the minimal effective concentrations of sodium dodecyl benzene sulfonate (SDBS) to completely eliminate Poterioochromonas sp. and Hemiurosomoida sp. were 8 and 10 mg L−1, respectively, yet the photosynthesis and viability of Chlorella was not significantly affected. These results were further validated in Chlorella mass cultures in 5, 20, and 200 m2 raceway ponds. Conclusions A chemical method using 10 mg L−1 SDBS as pesticide to control predatory flagellate or ciliate contamination in Chlorella mass culture was proposed. The method helps for a sustained microalgae biomass production and utilization, especially for biofuel production.
