Promotion by SF6 of a Radiolytically Induced Chain Reaction for the Geometrical Isomerization of cis or trans-Butene-2 in Dilute Gaseous Mixtures
FOR several years SF6 has been used in radiolytic studies because of its high cross-section for capture of low-energy electrons and consequent effect on observable products resulting from positive-ion neutralization reactions. A reduced yield of H2 from irradiated propane has been reported1 and attributed to electron scavenging by the small proportions of SF6 present. On the other hand, SF6 does not affect the H2 yield from irradiated liquid unsaturates such as trans-butene-2 (ref. 2), indicating that ionic species may not be important with respect to H2 formation from these olefines.
Nitrous Oxide as a Scavenger for Electrons in the Radiolysis of Propane
RECENT investigations of the radiation chemistry of liquid hydrocarbons indicate that in these systems N2O reacts rapidly with electrons but relatively slowly with hydrogen atoms1. We have investigated the effect of N2O in the radiolysis of propane gas and the results obtained have led to information about the mechanism of hydrogen formation.
Same-Sex Marriage in the United States
This Chapter gives a brief analysis of the status of same-sex marriage in the United States prior to the US Supreme Court decisions of 2013 and the status of litigation and political reforms triggered in part by these court decisions. It shows that marriage is a central institution in the country’s rationale of family law in ways that separate it from other western countries that have allowed same-sex marriage.
