The hydrothermal method was used to obtain two new compounds of Np(V): benzoate [(NpO2)3(py) (C7H5O2)3(H2O)2] (1) and salicylate [(NpO2)(phen)(HOC7H4O2)] (2), where py = pyridine and phen = 1,10-phenanthroline. An X-ray diffraction analysis of these

The structures of three new Np(V) complexes [(NpO2)2(phen)2(C7H5O2)2] (I), [(NpO2)2(phen)2. (o-C7H4FO2)2] (II), and [(NpO2)2(phen)2(p-C7H4FO2)2] (III), where phen = 1,10-phenanthroline, were studied. Two NpO2+ cations in the complexes are bound to ea

The previously unknown Np(VII) compound Li[C(NH2)3]2[NpO4(OH)2]·6H2O (I), containing organic cations, was synthesized and studied by single crystal X-ray diffraction. In contrast to the relatively numerous structurally characterized salts of [NpO4(O

Mixed-cation salts of the general composition NaM2[NpO4(OH)2]·4H2O, where M = Rb (I, II) and Cs (III), were synthesized and structurally characterized. The compounds differ from each other in the structural organization. The Np central atom in [NpO4

Two procedures for preparing the compounds M(NpO4)2·nH2O (M = Mg, Ca, Sr, Ba) using boric acid were suggested. In the first procedure, samples of freshly prepared salts M3(NpO5)2·nH2O (M = Ca, Sr, Ba) are treated with excess 0.5 M H3BO3 with vigoro

Early versions of satellite nadir-viewing UV SO2 data products did not explicitly account for the effects of snow/ice on retrievals. Snow-covered terrain, with its high reflectance in the UV, typically enhances satellite sensitivity to boundary layer
