By storing the cantaloupe fruit in the optimum conditions, it can be provided over a longer period of time with a more optimal quality in the domestic markets; its exports to other countries can be expanded and developed. This study was intended to utilize ethylene absorbents in order to preserve postharvest characteristics in the cantaloupe fruit. Therefore, fruits of Cucumis melo were stored ...
TiO2 is a very well-known and well-researched material due to the stability of its chemical structure, biocompatibility, and its physical, optical and electrical properties. In this study, the synergistic effect of nano-TiO2 immobilized on activated carbon, zeolite Y and ZSM-5 on the removal of styrene vapors from polluted air was investigated. The prepared catalysts were characterized by SEM, ...
Objective(s): Binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. Materials and Methods: Template free ZSM-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/ZSM-5 hybrid composites with nano chitosan...
در این مقاله، زئولیت nayبه روش سل-ژل و بدون حضور الگوهای آلی و افزودنی ها سنتز شد. سپس با استفاده از روش تبادل یونی به زئولیتagy تبدیل شد. در مرحله بعدی، نانوذرات منگنز دی اکسید در منافذ زئولیت agy به روش فضای محدود(cs) سنتز شدند. کامپوزیت nano-mno2/zeolite agy به روش های sem، xrd، ir و aas مورد شناسایی قرار گرفت. رفع و دفع آلودگی 2-کلرو اتیل فنیل سولفید (شبه عامل خردلی) و دی متیل متیل فسفونات ...
Many eff orts to improve the performance of heterogeneous catalysts and adsorbents focus on creating materials that are highly active and selective for their target reactants and products. Th is typically involves the use of porous solids with high surface areas, for instance crystalline or amorphous inorganic compounds, whose diff usional access, adsorption, and reaction properties depend stro...
Functionalized nanoporous materials have been developed recently as bio/chemical sensing materials. Due to the huge specific surface of the nano-materials for molecular adsorption, high hopes have been placed on gravimetric detection with micro/nano resonant cantilevers for ultra-sensitive sensing of low-concentration bio/chemical substances. In order to enhance selectivity of the gravimetric r...
