TL;DR: In this article, a di(2-ethyl hexyl) orthophosphoric acid system was used for the extraction of tracer-level cerium from a 10 M HNO3 aqueous phase into a 0·75 M, or 0·30 M, solution in n-heptane.

TL;DR: In this paper, the partition of tracer-level lanthanides, yttrium, and americium between various tri-n -butyl phosphate (TBP) phases and aqueous nitric acid phases has been studied radiometrically as a function of solvent concentration, Nitric acid concentration, and Z.

TL;DR: In this article, a flow sheet utilizing this solvent extraction system and involving both the trivalent and tetravalent states of Bk has been devised, using a raw berkelium fraction, isolated in the preliminary processing of an exhaustively neutron-irradiated plutonium sample, as feed, and a Bk 249 product was isolated in approximately 97% yield with established alpha decontamination factor and beta decentamination factor of approximately 6 × 10 3 and 9 × 10 5 respectively.

TL;DR: In this article, the authors investigated the mutual separation of Th(IV), Pa(V), and U(VI) in the system aqueous HCl-TBP (tributyl phosphate) without diluent.

TL;DR: In this article, a search was undertaken for acids belonging to the hydrogen fluoride system, and it was found that due to the extremely acid nature of the solvent, the substances capable of acting as acids in it were indeed limited in number.

TL;DR: In this paper, an octavalent oxyfluoride, OsO 3 F 2, the parent of the trifluoroperperosmates, M I OsO3 F 3 (M I = K, Cs, Ag), was described together with its reaction with hydrochloric acid under varying conditions.

TL;DR: In this paper, a number of peroxide, peroxide hydrate, and superoxide samples were scanned in the rock salt region of the infra-red and a special modification of the KBr disc technique was developed.

TL;DR: In this article, the valence-state ionization potentials of the metal dicyclopentadienyl derivatives of Ni and Cu were examined in relation with the dπ valence state ionisation potentials, and the relative instability of the compounds of these metals deriving from the higher valence states of high co-ordination number was discussed in relation to valencestate excitation energies.

TL;DR: In this paper, a stable rhodium(III) perchlorate hexahydrate, Rh(ClO4)3·6H2O, has been prepared by reaction of perchloric acid with Rhodium (III) chloride.

TL;DR: Inorganic salts are appreciably soluble in organic media, principally of the oxygenated forms (alcohols, ketones, ethers, esters), when they are capable of forming neutral molecules in solution as discussed by the authors.

TL;DR: The mass range 124 −135 of iodine isotopes formed in 170 MeV proton-induced fission of uranium has been studied using an electromagnetic isotope separator to prepare mass-determined samples for Geiger-Muller counting as mentioned in this paper.

TL;DR: In this paper, the hindrance factor in alpha decay is defined in terms of constants A and B which are empirically determined for each element and determined by fitting even-even alpha-decay rates.
