High energy binding sites

On the other hand, some of the questions that the experiments tried to address continue to be asked today. Chief among these is the question of where on the nanotubes is adsorption occurring. This is especially true for the high energy binding sites. Experiments have not yet resolved the question of what gases, if any, can adsorb on the ICs. 

Bonzel and Ku investigated the interaction of CO and H2S over Pt(lOO). As shown in Figure 27, sulfur preferentially poisons the sites of high-energy binding states of CO, as indicated by the shift in the CO desorption peaks toward lower temperatures. Sulfur-platinum interaction was also studied by IR spectroscopy of coadsorbed CO. 

There is not any critical hypoxic threshold for modification of the 3-(2-carboxypiperazin-4-yl) propyl-1-phosphonic acid high-affinity binding site of the N-methyl-D-aspartate receptor, but modification is coupled to a gradual decrease in brain cell energy metaboUsm and increase in hpid peroxidation (Fritz et al. 2001).
