The hydroxyl radical (OH) plays a central role in tropospheric chemistry, as well as influencing the lifetimes of some greenhouse gases. Because of limitations in our ability to observe OH, we have historically relied on indirect methods to constrain

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

The structure and properties of the needle-like phase of crystalline compounds of the general composition Co(NH3)6NpO5·nH2O, precipitated from alkaline Np(VII) solutions with [Co(NH3)6]3+ ions, were studied. The needle-like phase under the layer of
