Catalytic converter initial tests

The wide use of catalytic converters in 1975 was met with some concern and criticism. Initial concerns were focused on the potential high exhaust system surface temperatures to cause fires. Extensive testing conducted by vehicle manufacturers and by others indicated that exhaust system temperatures were no... 

The initial reaction mixture is based on different topoisomerase II buffers cited in the literature. In order to study the catalytic properties of the T. maritima enzyme, several parameters, such as ATP, Mg, pH, bovine serum albumin (BSA), and spermidine, have been tested. The DNA gyrase completely converts 200 ng... 

To test this, we need a. system in which the metathesis products do not themselves metathesize, so (hat we can be sure that we are seeing the inilial products. Perhaps the best example is shown in Eq. 12.11, in which 12,2 is converted into ethylene and phenanthrene, neither of which metathesize further with the particular Mo catalyst chosen. The initial isotope distributions in the products will then truly reflect a single catalytic cycle. The results of this reverse double cross showed a 1 2 1 mixture of the and d isotopomers of the result-...
