Transient enhanced

Temporal alterations in peripheral chemoreceptors are rare in vertebrates, but this group provides an example of transient enhancement of signal capture efficiency. The Red-backed salamander (Plethodon cinereus) shows dimorphic and seasonal VNO volume fluctuations. Males always possess a significantly larger vomeronasal area, and both...

The reverse time effect of diffusion was modeled by using equations 47-51. The 900 °C RTA step causes the damage anneal time, ta, to decrease relative to the 800 °C anneal. Thus, the duration of transient enhanced diffusion decreases as the RTA anneal time increases. Calculations using this model are shown in Figure 25. 

All the hypnotic subjects reported boredom and apathy. Their voices became flat and their expressions listless. One subject became hostile and mildly sadistic. All hypnotic subjects reported difficulty in thinking, and two seemed to become paranoid in the trend of their thinking. One subject reported transient visual and auditory hallucinations, which he did not specify, and transient enhancement of visual and taste sensations. This same subject reported, "... distant objects seemed more distant and unreal than usual, while objects close to me were vivid and dazzling."...

Figure 2.20 Chronoamperometric transients of disulfides molecules with sulfonate terminal copper deposition on various thiol and disulfide groups is evident, in contrast to the transient derivatized copper electrodes. The transients enhancement of inhibition provided by were measured in an acidified CuS04 electrolyte molecules with OH, COOH or CH3 terminal containing 88 Xmol L-1 PEG and 1 mmol lA1 Cl. groups [12].

The power of this method of analysis is shown, for example, in (ref.8) where the presence of the transient enhancement of water gas shift, an "activity change" process, was demonstrated. Although we were able to separate the two types of transient processes to some extent using CO measurements alone, in general, one requires measurement of more than just CO. Especially critical is measurement of O2. 

Presence of a close contact between the Pt and Ce02 appears a fundamental requirement for the occurrence of the active state. Consistently, a decrease of the particle size of the Ce02 supported on A1203 increases the efficiency in the improvement of the catalytic activity by the reduction treatment. These transient enhancements of the catalytic activity were attributed to the presence of a SMSI state induced by the reduction, which creates some highly active NM-Ce02 interfacial sites (Golunski et al. 1995). In our view, the decrease of H2 chemisorption alone is not sufficient to attribute this transient effect to a SMSI-type phenomenon. As discussed above, the onset of metal decoration requires reduction temperatures higher than 773 K.
