Toughening effect of mullite whisker within low-density ceramic proppants
Main crystal phases of low-density ceramic proppants prepared by bauxite and feldspar are granular corundum and whisker-shaped mullite. Mullite whiskers are interlocked with one another and piled up inside the pores. High aspect ratio of mullite whiskers

Structured sorbents for Direct Air Capture: The impact of materials and chemicals on performance
Abstract Structured sorbents can efficiently process large air volumes required for Direct Air Capture (DAC), but their broad implementation is limited by challenges in producing reproducible and homogeneous materials. This work presents a robust procedure to graft amines onto monolithic sorbents and systematically investigates how CO2 capture ...

The Material Basis of 18th‐Century Meissen Porcelain
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

This review explores the potential of multimetallic organic framework (MMOF) composites as photocatalysts. It demonstrates the impact of the composite architecture on the photocatalytic performance and existing challenges. The paper highlights heterojunction mechanisms and the role of each partner composites in degradation, CO2 reduction, H2 production,

The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Microstructural Analyses of Salt‐Glazed Ceramics
ABSTRACT Defining features of certain salt‐glazed studio pottery are a surface texture akin to orange peel, with mm‐scale dimples across the ware, and fine‐scale cracking within the salt glaze. There is remarkably little information in the scientific literature to explain the reasons for the formation of the orange peel effect or to specify the length ...

3D Printing of Porous Mullite From Sol–Gel Photocurable Powder‐Free Ink
ABSTRACT Porous mullite (AlVI2(AlIV2+2xSi2−2x)O10−x, where x ranges between 0.17 and 0.57) structures were fabricated by integrating sol–gel chemistry with digital light processing (DLP), enabling complex geometries with coupled micro‐ and macroporosity.

ABSTRACT Several industrial by‐products, process residues, and naturally extracted resources are rich in iron, providing a strong basis to explore their potential as cementitious materials. Cementitious composites in which ferrous carbonate is the primary binding phase have been investigated intermittently over the last decade.
