Transitions other tests

Mechanieal Tests and Polymer Transitions 15 Other Tests... 

Experimental studies within the PNP gas cloud program were conducted and evaluated by the Fraunhofer Institute for Chemical Technology using flammable mixtures of hydrogen and other fuels with air in different shapes (sphere, hemisphere, tube), confined or unconfined. They are described in more detail in section 8.5.2. Experimental results from other test programs in the USA (explosion series in FLAME ) or Norway (jet ignition with transition to detonation in acetylene-air mixtures) were also taken into account. All tests were close to the go - no go boundary between deflagration and detonation. 

Dissolution of transition-metal salts in an IL improves the 1-hexene/ n-hexane separation via the formation of a metal-olefin complex with silver nitrate outperform the other tested materials. Therefore [BM1M][N03] plays an important role in the separation process, due to its ability to isolate the silver cation fi om the nitrate anion, thereby producing a large amount of silver ions for the metal-olefin complexation, resulting in improved performance. 

Note 9—DSC will not differentiate between solid-liquid and solid-solid transitions other techniques must be used for example, melting point in accordance with Test Method D 87. 

The technique most often used (i.e., for an atom transfer) is to hrst plot the energy curve due to stretching a bond that is to be broken (without the new bond present) and then plot the energy curve due to stretching a bond that is to be formed (without the old bond present). The transition structure is next dehned as the point at which these two curves cross. Since most molecular mechanics methods were not designed to describe bond breaking and other reaction mechanisms, these methods are most reliable when a class of reactions has been tested against experimental data to determine its applicability and perhaps a suitable correction factor.
