Transmission electron microscope (TEM), ultraviolet-visible (UV/vis), electrospray mass spectrometric (ESMS), and X-ray photoelectron spectroscopic (XPS) studies are presented on a little studied rhenium hydrosol system produced by reduction of aqueous K 2 ReCl 6 with hydrazine in the presence or absence of a gum arabic protecting agent. The studies indicate that hydrazine-generated "rhenium hydrosols" are unstable in water and slowly dissolve over time in aqueous media to form the highly stable perrhenate ion.

Rhenium glass microspheres composed of metallic rhenium particles dispersed within a magnesium alumino borate glass matrix were produced by sintering ReO 2 powder and glass frit at 1050Β°C. The in vitro chemical durability of radioactive and nonradioactive microspheres was determined from chemical co
Xylan with glucuronic acid functionalities, separated from birchwood, was converted into hydrogels by dissolving it together with chitosan in acidic conditions. The hydrogels were formed at certain xylan/chitosan compositions. The mechanism of the gel formation was investigated with FTIR. Complexati
