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

open access: yesJournal 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 ...

Photolytic and thermolytic decomposition products from iron pentacarbonyl adsorbed on Y zeolite [PDF]

open access: yes, 1985
Zeolite supported iron systems obtained by photolysis and thermolysis of Fe(CO)5/Na---Y adducts are characterized via evaluation of the respective magnetic isotherms taken with a FONER magnetometer at T = 4.2 K.

Advanced Porous Materials for Maritime Carbon Capture

open access: yesAdvanced 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.

Enhancement of CO2/CH4 Adsorptive Selectivity by Functionalized Faujasite Zeolite [PDF]

open access: yesJournal of Ultrafine Grained and Nanostructured Materials, 2018
In this work, we have modified a synthesized Y-type zeolite (Si/Al = 2.5), with three different amines to investigate of the influence of adsorbent’s surface modification on CO2 selectivity over CH4.

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

open access: yesChemCatChem, 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

open access: yesThe 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 ...
