چکیده

This Communication reports simultaneous tracking of structural and kinetic information for the photoinduced elimination reaction of 1,2-diiodotetrafluoroethane in solution by transient X-ray diffraction. The transient structure of .CF2CF2I is determined to be a classical mixture whereas .CH2CH2I is bridged. Compared with the gas phase reaction, the secondary dissociation of .CF2CF2I into C2F4 and I is slowed down by a factor of 6 in solution. Transient X-ray diffraction offers a complementary method for capturing transient structures in solution which might be invisible or "optically silent" in time-resolved optical spectroscopy.

TOPOLOGY OPTIMIZATION OF STRUCTURES UNDER TRANSIENT LOADS

In this article, an efficient methodology is presented to optimize the topology of structural systems under transient loads. Equivalent static loads concept is used to deal with transient loads and to solve an alternate quasi-static optimization problem. The maximum strain energy of the structure under the transient load during the loading interval is used as objective function. The objective f...
