Journal of the Chinese Chemical Society, EarlyView.While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Journal of Quaternary Science, EarlyView.ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Rate phenomena in uranium extraction by amines [PDF]
, 1979 Kinetics studies and other rate measurements are reviewed in the amine extraction of uranium and of some other related and associated metal ions. Equilibration is relatively fast in the uranium sulfate systems most important to uranium hydrometallurgy ...

The Behavior of Uranium in the Extraction with Benzyldodecylamine
Nippon kagaku zassi, 1961 アミン類は選択性の面で他の溶媒とくらべてすぐれているため,ウランの抽出に広く使用されている。このうちペンジル基をもつ第ニアミン類は高い抽出力をもち着目されているが,こめ種のアミン類による抽出の基礎が明らかでない。したがってベンジルドデシルアミンを使ってウランの抽出挙動および抽出機構を調べた。硫酸ナトリウム0.1～1.0mol/l,酸性度0.1～1.0Nの広い範囲でウランは1:1硫酸錯塩の形で実質上完全に有機層に抽出され,有機層内では抽出された硫酸ウラニル1分子についてベンジルドデシルアミンの4個が配位する。

Journal of Quaternary Science, EarlyView.ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.
