One can find pKa values for the conjugate acids of some actual (good) to compare with hypothetical (bad) leaving groups: for example in the bacterial conversion of serine to cysteine, the conjugate acid of the hypothetical leaving group hydroxide ion is water. But sometimes in the absence of...
which is usually believed to be unfavourable but in fact has little influence on the performance. The conversion during the charge/discharge process is free of any massive structural evolution, but with some tiny shuffling or adjustments of atom/ion species. The results not only unravel that the...
The active material also may be useful for: an analytical and prepative-scale chromatographic support; an ion exchange media; a coupling agent for biological materials such as enzymes, whole cells, yeasts, proteins, microbes, pharmaceuticals including timed-release drugs, and vaccines; stabilization ...

The absorption peak at 960 cm−1 is typical of the Si-O-Si stretching indicating the presence of Si-O-(Al) bonds. The Si-OH group are responsible for the shoulder at 860 cm−1. Figure 2. IR spectra for allophane (a) and for ZnAl-SO4 LDH (b). In Figure 2b, the infrared...
2.6. Ion Exchange Process The ion exchange process is used when the desired interlayer anions are not fit to be incorporated utilizing urea or coprecipitation strategies. The preferred anion replaces the anions existing in a formerly arranged layer double hydroxide. Nitrate and chloride anions are ...
a hydrogen atom is donated by the SiO or SiOH oxygen atom to form a stable leaving group such as water or alcohol in a hydrolysis reaction. At low pH, a hydroxide ion (during hydrolysis, formed by deprotonation of a water molecule) or a SiO ion (during condensation, also formed via dep...
