Durability of Concrete With Coal Gasification Slag and Coal Gangue Powder [PDF]

open access: yesFrontiers in Materials, 2022
Lack and quality decrease of supplementary cementing materials (SCMs) such as fly ash and granulated blast-furnace slag is increasingly prominent in China. Thus, the use of coal gangue (CG) and coal gasification slag (CGS) as SCMs in concrete attracted more researcher’s attention.

Enhancing Interfacial Dioxygen Bridging Dynamics of Waste-Derived Cathode Catalysts for Augmented High-Rate Performance in Li-O<sub>2</sub> Batteries. [PDF]

open access: yesAdv Sci (Weinh)
This study fabricates Fine Slag/Ti4O7@TiC hybrids with interfacial dioxygen bridge coupling to optimize oxygen redox dynamics in lithium‐oxygen batteries (LOBs). Lattice distortion from oxygen vacancies and inherent charge repulsion of Ti‐O‐C interfacial coupling reconstruct and refine the surface coordination environment.
