These data may be somewhat inaccurate since they were taken (by us) from a graph (Pons, 1980, Fig. 3), and furthermore are evidently preliminary. The predicted room temperature energies are E T (300°K) a 0.71 eV, and Eq (300°K) a 0.68 eV, again, with respect to the conduction band. Thus, Pons s results are in good agreement with those of Martin et al (1980b), except for the temperature dependence of the Cr level. He finds ECr below E0 at room temperature, as we do, but the difference is smaller than that predicted by our electrical measurement data described here [Eqs. (25a) and (25b)]. It seems, therefore, that further investigations of the temperature dependences of the (EL2) and Cr levels will be necessary. 

Since the reactions are carried out at room temperature, energy savings are possible. 

This technique ensures good interfacial contact between the layers which in turn leads to low internal resistance (and thus to high rate capability) and to long cycle life. A cyclability of up to 1500 cycles to a cut-off of 80% of initial capacity at the 1 C rate at room temperature, energy densities of the... 

X-ray film has been traditionally the mainstay both of diagnostic radiology and XRD. Efforts to replace it with digital detectors, such as the photo-stimulated luminescence plate [8], have benefited both fields. There has been enormous investment in silicon-based X-ray detectors enabled by the semiconductor industry, and these are found in increasing measure in conventional X-ray diffractometers. Room temperature energy-resolving... 

The deactivation model was developed using room temperature energy transfer data that were obtained under conditions where Av = 2 events could not be detected. For collisions with He, the low temperature measurements described above did show Av = —2 transfer, and provided an estimate for the relative magnitudes of the Av = — 1 and Av = —2 rate constants. To examine the influence of multiquantum transfer on the deactivation model, we recently included Av = 2 channels. To estimate the... 

It has been shown [155,171] that the dependence of excimer emission intensity on acceptor concentration obeys the Stern—Volmer equation whether M or D is the donor, whereas a second-order equation is obtained if both types of excited state simultaneously act as donor. It seems that in poly-1-vinylnaphthalene and polyacenaphthalene films at room temperature, energy transfer to benzophenone occurs from M, although normal fluorescence cannot be detected in the emission spectrum of the polymers in these conditions [155]. Decay time measurements have shown that the excimers in solid polyvinylcarbazole are traps rather than intermediates in the energy transfer process [148]. With polystyrene, however, it has been clearly demonstrated that energy transfer to tetraphenylbutadiene occurs from both excimer and isolated excited chromophore [171].

CSA as the coupled-channel expansion in the entrance channel contains the orbital spherical harmonics, the sum over which in equation (15) achieves the partial-wave expansion. For light-heavy-light reactions at room temperature energies, the maximum value of J required is about 20 and the ESA-CSA computations will then be 20 times cheaper than the CSA...

The reclamation of scrap metal from old cars also uses cryogenic technology—cooling to low temperatures permits easier fracturing and component separation. Car bodies can be pulverized at low temperatures with about one-tenth of the room-temperature energy requirement. Rubber tires and other scrap materials are similarly processed by cryogenic recovery techniques.
