Ca-looping for postcombustion CO2 capture: A comparative analysis on the performances of dolomite and limestone [PDF]
The low cost and wide availability of natural limestone (CaCO3) is at the basis of the industrial competitiveness of the Ca-looping (CaL) technology for postcombustion CO2 capture as already demonstrated by ~1Mwt scale pilot projects.

Electrical resistivity of carbon films [PDF]
The electrical resistivity along 500 A thick carbon films has been measured from 1.2 to 1100°K. The electrical resistivity measurements at high temperature indicate a change in the structure of the film beginning at about 670°K. In the theory of non-crystalline solids by Mott, the temperature dependence of the electrical conductivity σ, at low ...
