Time-resolved atmospheric pressure results

Figure 4 represent the XRD results for Tobermorite dehydration using the in-situ XRD set up. It clearly shows the time-resolved evolution of the Tobermorite structure during dehydration obtained with the above mentioned heating procedure under atmospheric pressure. Many authors [7,13] describe the first step of Tobermorite dehydration [14 A-11 A] as being a reversible process. 

The rate constants for the reactions of OH with a series of organic nitroalkanes, nitrites and nitrates and of NO with a series of peroxy radicals were measured at 298 K and a total pressure of 1 atm. The rate constants were obtained using the absolute technique of pulse radiolysis combined with time-resolved UV-VIS spectroscopy. The results are discussed in terms of reactivity trends and the atmospheric chemistry.
