European Journal of Inorganic Chemistry, Volume 28, Issue 26, September 24, 2025.Calcium silicate materials are synthesized using eggshell waste as a sustainable calcium source. Quaternary ammonium salts are employed as key structure‐directing agents, favoring the formation of the clay‐like mineral rhodesite with a significantly higher surface area than previously reported. The hemostatic performance of the synthesized materials is

Faujasite catalyzed nitrodeiodination of iodopyrazoles
Catalysis Communications, 2013 Abstract Nitrodeiodination of iodopyrazoles using nitric acid/Faujasite has been investigated. The present procedure is simple, rapid and convenient and requires no sulfuric acid or oleum and may be applied for the synthesis of several nitropyrazoles in good yields in drug and pharmaceutical industries.

A New Source of Reaction - Diffusion Coupling in Confined Systems due to Temperature Inhomogeneity [PDF]
, 2002 Diffusion is often accompanied by a reaction or sorption which can induce temperature inhomogeneities. Monte Carlo simulations of Lennard-Jones atoms in zeolite NaCaA are reported with a hot zone presumed to be created by a reaction. Our simulations show

Carbon Neutralization, Volume 4, Issue 5, September 2025.A composite solid polymer electrolyte was designed by incorporating LiX zeolites into polyethylene oxide matrix. This design enhances the ionic conductivity, achieves long‐term cycling stability (85.71% capacity retention within 800 cycles) and supports all‐solid‐state pouch cells under mechanical abuse conditions such as folding, twisting, and cutting.

Enhancing mechanical properties of ceramic papers loaded with zeolites using borate compounds as binders [PDF]
BioResources, 2013 NaY zeolite-containing ceramic papers were prepared by a papermaking technique with a dual polyelectrolyte retention system that implied the use of cationic and anionic polymers. To improve their mechanical properties, we found that some borate compounds
