Poly (cyclotriphosphazene-co-4,4 '- diaminodiphenylsulfone) (PZD) microspheres were synthesi zed by precipitation polymerization of Hexachlorocyclotriphosphazene (HCCP) and polyfunctional organic monomers. The products characterized FTIR, SEM-EDS, XPS bet. adsorption behavior PZD for uranium (VI) in aqueous solution the influence disc ussed. results show that have a certain capacity queous solu...

Functionalized phenols based on tyramine were synthesized in order to be selectively grafted on to hexachlorocyclotriphosphazene, affording a variety of functionalized dendrons of type AB(5). The B functions comprised fluorescent groups (dansyl) or dyes (dabsyl), whereas the A function was provided by either an aldehyde or an amine. The characterization of these dendrons is reported. An unexpec...

The anodically first formed oxide on gold (oxide I) reaches two complete monolayers, ie 1.5 rnCcm_’ oxide charge, before a ssond type of oxide (oxide II) starts to form. Electrochemical redox reactions with redox couples such as the tris(o-phenantroline) ferrous/ferric ion couple and others which are well known to behave reversibly on bare gold are inhibited completely by gold covered with this...
