Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.Abstract The novelty of this study is to present a multilayer framework for predicting the air‐entrained porosity of cement paste based on the molecular characteristics of nonionic surfactants. Air‐entraining agents enhance concrete durability against freeze–thaw damage; however, their development is labor‐intensive and cost‐prohibitive.

Optimizing Zeolite 13X Synthesis from Kaolin Clay for Higher CO2 Adsorption: A Statistical Approach
ChemCatChem, Volume 17, Issue 22, November 24, 2025.Zeolite 13X is synthesized using kaolin clay as primary raw material through controlled variation of SiO2/Al2O3 ratio; aging time; crystallization temperature; and crystallization time. Statistical analysis identifies the influence of each synthesis parameter on CO2 adsorption capacity.
