The Stability Constants of Nickel(II) Complexes with Chloride, Thiocyanate, Sulfate, Thiosulfate, and Oxalate Ions, as Determined by a Solvent Extraction Method [PDF]

Bulletin of the Chemical Society of Japan, 1976
Abstract The stability constants of nickel(II) complexes in 1 mol dm−3 sodium perchlorate media were determined at 25 °C by means of a solvent extraction method. The values thus obtained for logβ1 and logβ2 are: 0.0 and no second complex (Cl−), 1.1 and 1.6 (SCN−), 1.0 and 1.4 (SO42−), 0.9 and 1.3 (S2O32−), and 3.7 and 6.6 (C2O42 ...

Variation of stability constants of thorium and uranium oxalate complexes with ionic strength [PDF]

, 1993
Extraction of Th(IV) and UO{sub 2}{sup 2+} by a solution of TTA and HDEHP, respectively, in toluene was used to obtain stability constants of their oxalate complexes in 1, 3, 5, 7 and 9 M ionic strength (NaClO{sub 2}) solutions. The complexes formed were

The Synergistic Effect in Solvent Extraction. The Effect of the Chelating Ligands on the Stability Constant of Lutetium β-Diketonate Adducts with TOPO [PDF]

Bulletin of the Chemical Society of Japan, 1969
Abstract The steric effect and the inductive effect of the functional groups of β-diketones on the adduct formation between lutetium chelates and TOPO in benzene was studied by using various β-diketones with aliphatic groups (acetylacetone, dipropionylmethane, pivaroylacetone, diisobutyryl-methane and dipivaroylmethane), aromatic groups (

The thermodynamic chemistry of the aqueous copper-ammonia thiosulfate system [PDF]

, 2006
A fundamental thermodynamic study was undertaken in order to establish the speciation of copper(I) and copper(II) during the leaching and recovery of gold from thiosulfate-copper-ammonia solutions. Despite considerable research into this complex leaching

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
