A Space-Based Solar Screen Against Climatic Warming, Michael Noah Mautner
A Space-Based Solar Screen Against Climatic Warming, Michael Noah Mautner
Chemistry Publications
The expected global warming may be reversed by space-based screen that would intercept a fraction of the solar radiation incident on Earth. Warming by 2-5oC could be prevented by intercepting 3-7%, respectively, of the incident solar radiation. The screen may be constructed for example of a thin film, a grid of film supported by a mesh or fine-grained dust deployed in orbit about the Earth. For an average film thickness or particle radius of 0.001 cm, the required mass is 1014 - 1015 g, equivalent to a medium sized lunar mountain or asteroid. The material may …
Observation Of Eliminative Cationic Polymerization Within Van Der Waals Clusters, M. Samy El-Shall, K. E. Schriver
Observation Of Eliminative Cationic Polymerization Within Van Der Waals Clusters, M. Samy El-Shall, K. E. Schriver
Chemistry Publications
We report the first observation of eliminative cationic polymerization within van der Waals (vdW) clusters following electron impact ionization at pressures of 10−8 Torr. The elimination reactions of C2H3Cl+ within the clusters terminate after three successive steps, each involving elimination of HCl or Cl. The results provide a mechanism for the early stages of gas phase cationic polymerization of vinyl chloride and demonstrate the feasibility of using vdW clusters as a means of studying gas phase cationic polymerization.
