The layered P2-Nax MO2 (M: transition metal) system has been widely recognized as electronic or mixed conductor. Here, we demonstrate that Co vacancies in P2-Nax CoO2 created by hydrogen reductive elimination lead to an ionic conductivity of 0.045 S cm(-1) at 25 °C. Using in situ synchrotron X-ray powder diffraction and Raman spectroscopy, the composition of the superionic conduction phase is e...
Study of physisorbed and chemisorbed carbon dioxide (CO2) species was carried out on the NaX zeolite modified by cationic exchanges with bivalent cations (Ca2+ Ba2+) temperature-programmed desorption CO2 (CO2-TPD). Others results were obtained infrared to complete study. The this research showed, in physisorption region (213 - 473 K), that increase slightly interactions molecule adsorbents and/...
A series of experiments were designed to utilize the Taguchi method for investigating the effects of important parameters on the synthesis of NaX zeolite and to find the best conditions of synthesis. An L9 orthogonal design of Taguchi approach was applied to design experiments consisting of 9 trails. The effect of molar composition, including SiO2/Al2O3 and Na2O/Al2O3 ratios, and the crystalliz...
this study was carried out to evaluate how various amounts of nanozeolite decrease the effects of aflatoxins (af) on color and oxidative stability of the broiler thigh meat. three hundred and thirty six one-day-old ross 308 male broiler chickens were divided into six groups including a control group, which received diet without af and nanozeolite, and five treatment groups that received diet wi...
In the present work, the nano-NaX zeolite and micro-NaX zeolite were synthesized via hydrothermal method. Then, the adsorption capacities and isotherms of pure gases CO2 and CH4 on the synthesized zeolite nanoparticles were determined at three temperatures of 288, 298 and 308 K and various pressures from 1 up to 20 bar. Adsorption capacities of CO2 on the nano-sized zeolites NaX were showed to ...

This paper discusses the unprecedented microscopic findings of micellar growth in colloidal system (CS) of catalyzed piperidinolysis of ionized phenyl salicylate (PS-). The giant vesicles (GV) was observed under the optical polarization microscope (OPM) at [NaX]=0.1M where X=3-isopropC6H4O-. The conditions were rationalized from pseudo-first-order rate constant, kobs of PS- of micellar phase at...
برای جداسازی هیدروژن از مخلوط های گازی غشاءجدید Pd-SiO2/PSS/NaX با استفاده از نانو زئولیت سدیم، NaX و بر پایه فولاد متخلخل، PSS طراحی و ساخته شد. در ابتدا نانو زئولیت سدیم به روش هیدروترمال سنتز و با استفاده از خلاء بر روی سطح فولاد متخلخل نشانده شد و در گام بعدی کاتالیست Pd-SiO2 سنتز و به روش سل-ژل بر روی پایه PSS/NaX رسوب داده شد. در نهایت کاربرد مجموعه Pd-SiO2/PSS/NaX برای تصفیه هیدروژن مورد...
