PHASE TRANSFORMATION IN THE FORMATION OF FAUJASITE FROM FLY ASH [PDF]

open access: yesIndonesian Journal of Chemistry, 2010
Faujasite was hydrothermally synthesized from fly ash at 100oC in alkaline solution by reflux with 5M HCl and fusion with NaOH pretreatments. Phase transformation in the formation of faujasite was performed by variation of NaOH/fly ash weight ratios and ...

SYNTHESIS OF FAUJASITE WITH HIGH THERMAL STABILITY FROM FLY ASH [PDF]

open access: yesIndonesian Journal of Chemistry, 2010
Faujasite was hydrothermally synthesized from fly ash at 100oC in alkaline solution by reflux with various concentration of HCl and fusion with NaOH (weight ratio of NaOH/fly ash = 1.2) pretreatments.

Transition phases of zeolite Faujasite type to Sodalite by thermal treatment [PDF]

open access: yesSemina: Ciências Exatas e Tecnológicas, 2015
The zeolites can have several functions as catalysts (biofuel production) and molecular sieves (treatment of contaminated areas). This study aims to characterize the zeolites obtained in the transition of a Faujasite like zeolite into a Sodalite, when ...

Nanometric Faujasite (FAU) Zeolite Ion-Exchanged With Metal Ions for Hemostatic and Antimicrobial Applications: A Thromboelastographic and Microbiological Study. [PDF]

open access: yesChem Asian J
Faujasite nanozeolite (NanoFAU) and its ion‐exchanged forms (Ag+, Ba2+, Ca2+, Mg2+) were synthesized and characterized to assess their biomedical potential. NanoFAU‐Ca showed superior hemostatic activity, while NanoFAU‐Ag exhibited strong antimicrobial effects against S. aureus and C. albicans.

Enhancing Dose Efficiency of Optimum Bright-Field Scanning Transmission Electron Microscopy Using a Phase-Shifted Electron Probe. [PDF]

open access: yesSmall Methods
ABSTRACT Observing beam‐sensitive materials using scanning transmission electron microscopy (STEM) at low electron dose conditions is challenging due to the low signal‐to‐noise ratio (SNR) of images. In this study, we aimed to improve the SNR of optimum bright‐field (OBF) STEM by introducing phase shifts to the incident electron probe using lens ...

Potential Zeolites Related to Faujasite (FAU): Structures and Energetics. [PDF]

open access: yes, 2020
We present a small set hypothetical zeolite frameworks that are structurally related to faujasite. They are found by examination of the -t nets of the Frank-Kasper phases, which optimize the conditions for regular-tetrahedral nets.

Energetic Characterization of Faujasite Zeolites Using a Sensor Gas Calorimeter [PDF]

open access: yes, 2021
In addition to the adsorption mechanism, the heat released during exothermic adsorption influences the chemical reactions that follow during heterogeneous catalysis. Both steps depend on the structure and surface chemistry of the catalyst.
