... y15% of all known solids containing short Xe–C, Xe–N and Xe–Cl contacts have been structurally characterized. Selected structures are shown in Fig. 2. XeII is isoelectronic to II. Not surprisingly, XeF2 is isostructural with the linear symmetric IF22 anion (present for example in its Cs+ salt), and ...

Heterogeneous catalysis on chitosan
... (DA) that controls many properties of the polymer: its acid–base properties and its solubility [50]. Indeed, the intrinsic pKa of chitosan depends on the degree of deacetylation, the ionic strength and the charge neutralization of amine groups; in practice it lies within 6.3–6.7 for fully neutralize ...
