Study on Coordination Chemistry of U(Ⅵ) with N,N-dimethyl-6-amide-pyridine-2-carboxylic Acid

open access: yesYuanzineng kexue jishu, 2023
The very strong complexing capacity of pyridine-2,6-dicarboxylic acid (DPA) with lanthanides/actinides of different oxidation states in aqueous solutions makes it a selective complexing agent or stripping agent in various separation systems. Besides DPA,

Lectures on Stability and Constant Scalar Curvature [PDF]

open access: yesCurrent Developments in Mathematics, 2007
An introduction is provided to some current research trends in stability in geometric invariant theory and the problem of Kaehler metrics of constant scalar curvature. Besides classical notions such as Chow-Mumford stability, the emphasis is on several new stability conditions, such as K-stability, Donaldson's infinite-dimensional GIT, and conditions ...

Recovery of Scandium from Sulfuric Acid Aqueous Solutions using Ion-Exchange Resin

open access: yesJournal of MMIJ, 2022
Ion-exchange process with chelating resins was investigated for recovery scandium from sulfuric acid aqueous solutions. An iminodiacetic acid type chelating resin, Diaion CR11, had a higher Sc adsorption selectivity than other elements.
