Novel Extraction of Chromatographic Resins Based on Tetraalkyldiglycolamides: Characterization and Potential Applications
TL;DR: In this article, two new extraction chromatographic resins containing the diglycolamide class of molecules have been prepared and characterized, and potential applications identified, and the new resins consist of 40 weight percent N,N,N′N′ tetraoctyldiglycamide (TODGA) and N, n,N',N′ n′ tetrakis−2−ethylhexylhexylcylcoxyldigcylcolamide (TEHDGA) sorbed onto 50-100µm particle size Amberchrom® CG

DIPEX: A new extraction chromatographic material for the separation and preconcentration of actinides from aqueous solution
TL;DR: In this article, a novel extraction chromatographic resin consisting of a liquid diphosphonic acid supported on an inert polymeric substrate for the sorption of actinides from strongly acidic chloride media is described.

TL;DR: In this paper, a goal-based dynamic action selection mechanism incorporating a model for emotions was developed for use with autonomous agents, and the model incorporated a reward prediction module that altered the effect of an event based on the error between when an event occurred and when it was predicted to occur, which resulted in the emotions returning to their steady state values unless there was continual reinforcement through the occurrence of events.

Extraction of selected transplutonium(III) and lanthanide(III) ions by dihexyl-N,N-diethylcarbamoylmethylphosphonate from aqueous nitrate media
TL;DR: In this paper, the extraction behavior of selected transplutonium (III) and lanthanide(III) ions fromnitrate solution was studied using relatively pure dihexyl-N, N-diethyl-carbamoylmethylphosphonate (DHDECMP).

THE EXTRACTION OF SELECTED ACTINIDES IN THE ( III) (IV) AND ( VI) OXIDATION STATES FROM HYDROCHLORIC ACID BY Oπ D( iB) CMPO: THE TRUEX-CHLORIDE PROCESS∗
TL;DR: In this paper, a generic actinide extraction/recovery process was developed for the removal of actinides from chloride salt wastes, based on the distribution ratios of tri-, tetra-, and hexavalent actiniders from chloride media.

The Continuation of the Periodic Table up to Z = 172. The Chemistry of Superheavy Elements*
TL;DR: The chemical elements up to Z = 172 were calculated with a relativistic Hartree-Fock-Slater program taking into account the effect of the extended nucleus as mentioned in this paper.

TL;DR: In this article, the influence of the amount of HDEHP on the height of the plate has been studied, and it was found that up to 10 % of the HP was sufficient to decrease the plate height to less than 0.33 mm, which makes possible very clear separation of adjacent rare earths at room temperature.

SCF Relativistic Hartree–Fock Calculations on the Superheavy Elements 118–131
Joseph B. Mann,James T. Waber +1 more
TL;DR: In this article, the energies of a number of configurations of the elements with atomic numbers 118-131 were computed by means of the relativistic Hartree-Fock method to establish the probable ground states.
