Chemistry – A European Journal, EarlyView.A semi‐empirical Stokes‐Einstein‐based model for describing the diffusion of organic, organometallic and coordination compounds is developed for the interpretation of diffusion constants obtained by diffusion‐ordered NMR spectroscopy (DOSY). This model uses the molecular volume as a descriptor and shows a high accuracy, enabling application to ...

Electrochemistry of Uranium [PDF]
Nature, 1946 AN account of the polarographic reactions of the uranium ions has just been published1. During 1944, experiments on this subject were made at this Laboratory, the publication of which has been delayed by war conditions. In general, our results confirm those of Kolthoff and Harris.

Deep Underground Science and Engineering, EarlyView.The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.
