Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

Water and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

Intercalated Mullite Glass‐Ceramic Composites From Co‐Sintering of Aluminosilicate Glass and Kaolinite

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT The co‐sintering of kaolinite with varying contents of jadeite‐type (Jd) glass yields mullite‐containing glass‐ceramic composites with tunable properties, offering fine control over the crystallizing phases and residual glass content. The Jd glass phase drastically decreases the sintering temperature by instigating a liquid phase sintering ...
