Abstract:
... Vacancy engineering has been shown to be an effective way to tune the electromagnetic parameters of electromagnetic wave (EMW) absorbers and improve their absorption properties. However, the current methods to induce the formation of sulfur vacancies are not enough, and the contribution of sulfur vacancies to EMW absorption has not been clearly described. This work proposes a method to induce sulf ...

Abstract:
... Failures of mine tailings storage facilities (TSF) can have profound and long-lasting effects on the downstream receiving environment. Virtually all spills to date have been into river systems without large lakes that may buffer downstream impacts. In August 2014, the failure of the Mount Polley copper (Cu)-gold mine TSF in British Columbia, Canada, released ~25 × 10⁶ m³ of water and solids; globa ...
