▪ Abstract Manganese (IV) oxides produced through microbial activity, ie, biogenic Mn
oxides or Mn biooxides, are believed to be the most abundant and highly reactive Mn oxide …

Radionuclides in the environment is an important issue, many techniques have been
developed for the removal of radionuclides from the environment. One of those techniques is …

This chapter focuses mainly on the basic principles and methods of X‐ray absorption near
edge structure and extended X‐ray absorption fine structure spectroscopy of soils, minerals …

Although minor in abundance in Earth's crust (U, 2–4 ppm; Th, 10–15 ppm) and in seawater
(U, 0.003 ppm; Th, 0.0007 ppm), light actinides (Th, Pa, U, Np, Pu, Am, and Cm) are …

Sorption of actinides, particularly plutonium, onto submicrometer-sized colloids increases
their mobility, but these plutonium colloids are difficult to detect in the far-field. We identified …

Reactions of the light actinide ions (Th to Cm) at the mineral− aqueous solution interface
have attracted much attention during recent years. Initially research was mainly driven by the …

More than a century of non-ferrous metallurgical activities have had a severe impact on the
natural environment leading, in most heavily contaminated sites, to a complete loss of the …

Bacterial Mn (II) oxidization by spores of Bacillus, sp. strain SG-1 has been systematically
probed over the time scale 0.22 to 77 days under in-situ conditions and at differing Mn (II) …

The mineralogy of natural ferromanganese coatings on quartz grains and the crystal
chemistry of associated trace elements Ni, Zn, Ba, and As were characterized by X-ray …

Actinide speciation by means of X-ray absorption fine structure (XAFS) is reviewed with
emphasis on actinide speciation in the field of nuclear disposal safety research. The XAFS …
