Phase Transformations, Microstructural Effects, and Photocatalytic Activity of Tungsten Trioxide‐Geopolymer Composites

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
 . ABSTRACT Water and air pollution are pervasive issues, impacting the majority of global citizens. In response, geopolymers functionalized with photocatalytic metal oxides have emerged as sustainable materials for environmental remediation. This study examines how the Si/Al molar ratio (1 and 2) and photocatalytic WO3 loading (WO3/Al molar ratios of ...

Cs+ and Sr2+ adsorption selectivity of zeolites in relation to radioactive decontamination

Journal of Asian Ceramic Societies, 2015
Zeolites are used as adsorbents of cationic elements in the radioactive decontamination process of water, soil and others. We determined Cs+ and Sr2+ adsorption selectivity of some zeolites to know effective zeolite species for the decontamination of ...

Advanced Porous Materials for Maritime Carbon Capture

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

Using Chemometrics for Unraveling Complex Property Activity Relationships in Zeolite Catalyzed Sugar Conversion

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
ABSTRACT The catalytic conversion of biomass‐derived sugars to 5‐hydroxymethylfurfural (5‐HMF) over zeolites is challenging due to internal mass transfer limitations arising from their microporous framework. To overcome this chronic issue, we prepared a set of micro‐mesoporous zeolites (22 samples), whose properties were fully characterized in our ...

Thermal degradation of impact‐modified PMMA in mechanical and chemical recycling

The Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 31-43, January 2026.
Abstract Poly (methyl methacrylate) (PMMA) is a thermoplastic with outstanding tensile strength, UV resistance, and a high level of transparency that has been used widely for optical applications such as glazing in the automobile industry. Mechanical recycling, the most widespread method, degrades the physical properties and prevents reusing PMMA in ...
