Olson, Randall J.; Coldwell, Karin D.; Compton, Bruce J.; Giddings, John C. | Sedimentation field-flow fractionation: a method for studying particulates in cataractous lens | It is shown that the technique of sedimentation field-flow fractionation (sedimentation [sed] FFF) can be used to determine the particle content and particle size distribution of normal and cataractous lenses. A 31-year-old normal human lens, for example, showed a particle content of 1.5% by weight ... | Fractionation; Cataractous Lens; Particulates | 1984 |

Armentrout, Peter B. | Threshold behavior of endothermic reactions: C+(2P) + H2 → CH+ + H | The reaction C+(2p) + H2 → CH+ + H (1) and its deuterium analog is a model system in ion-molecule chemistry. It is of interest due to its astrophysical significance, because it is an endothermic process, and because the interaction involves several potential energy surfaces. Experimental work ha... | Endothermic reactions; Translational energy; Threshold behavior | 1984 |
