99Tc is the most significant long-lived product of uranium fission, producing the largest fraction of the total long-lived radiation emissions of nuclear waste. Tc 7+ compounds are highly mobile in the environment. Relatively little is known regarding the solid state chemistry of Tc. Recently we studied the structural properties of (NH4)TcO4 (Tc7+) and confirmed that this is isostructural...

Because of their radioactive nature, solid technetium-99 oxides have been rarely studied, and there is
a dearth of modern spectra and diffraction patterns in the literature. This publication aims to address
this by detailing a low-temperature synthesis method for pure, crystalline alkali pertechnetates,
along with complete analysis by static and magic-angle-spinning nuclear magnetic...

One of the problematic types of LRW are alkaline wastes generated in some types of spent
nuclear fuel reprocessing. Environmental friendly biological techniques of LRW treatment
are not widespread because of its extremely high salt contents and alkalinity usually not
suitable for organisms. The aim of this work was to explore the use of microorganisms
from extremely alkaline habitat to...

Techetium has a great number of oxidation states (usually we say 9 but in fact much
more) and is evidently one of the elements with the most complicated chemistry. This is
due its position in the center of 4d elements row with 7 electrones available for chemical
bonding. One of the very special options complicating technetium chemistry is its ability to
cluster formation and especially the...
