We report on the design of both transmission and fluorescence x-ray-absorption spectroscopy cells suitable for in situ characterization of heterogeneous catalysts. The heart of both cells is a quartz tube used to house the catalyst sample. Both cells

A new form of time-resolved optoacoustics is described. In this method a fast piezoelectric transducer placed within a large chamber is used to detect individual condensation and rarefaction components of the acoustic waves generated by the relaxing

The multiphoton induced isomerization of cis-3,4-dichlorocyclobutene (DCCB) was studied as a function of pressure. Three experiments indicated the existence of a nonthermal mechanism at neat pressures below 60 mtorr. These were: (i) the leveling off

Pt particles in a highly dispersed Pt/γ-A12O3 catalyst have been found to undergo ordering following the removal of chemisorbed oxygen with hydrogen at room temperature. The very small Pt particles are found to be disordered following an initial red

In many analytical applications there is a need for a device to measure the energy or spatial profile of a laser pulse. Such a detector is also useful as a trigger for synchronizing various electronic devices with the laser pulse. Pyroelectric detect
