Laboratory Simulation of In-situ Leaching of Polyhalite

open access: yesProcedia Earth and Planetary Science, 2011
AbstractDeeply buried polyhalite is a kind of sulfate which contains about 28% potassium sulfate. Extraction potassium from polyhalite using in-situ leaching technology can help to resolve the problem of potassium shortage. This paper indicates a modeling study of leaching polyhalite in laboratory.

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...
