Membrane technology is important in industrial wastewater and water treatment. Recently, the polymeric membrane widely chosen these applications. However, they are lowtemperature ranges, low corrosion resistance, lifespan. Thus, researchers actively trying to develop a better such as natural clay ceramic due their excellent chemical, mechanical thermal high-pressure application long This detail...
this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....
در این تحقیق با استفاده از مدل سازی ریاضی، تراوایی مخلوط های ch4/h2 در نانوتیوب ها کربن تک دیواره (10،10) در دمای اتاق تعیین شد. شبیه سازی ها پیشین نفوذ بسیار سریع گازهای تک جزئی را در نانوتیوب ها کربنی نسبت به سایر مواد متخلخل نشان داده بود، مخلوط های دو جزئی نیز دارای نفوذ پذیری بالایی در نانوتیوب ها می باشند و در نتیجه غشاء نانوتیوب کربنی دارایفلاکس بسیار بالایی می باشد. فلاکس غشاء برای مخلو...
Currently, exchanging trends in the expensive usage of ceramic materials such as alumina, zirconia etc. into economical ceramic raw sources have been studied extensively over the last decade for various technological applications. Despite the fact that this ceramic compound or elements offer a great performance and stability, especially at high temperature and corrosive or acidic conditions, th...
Biosensors have experienced rapid, extensive development. To maintain the bioactivity of biomolecules and to give the electrochemical output signal required, appropriate bioimmobilization matrices for biomolecules are critical. In this review, we describe some advanced membrane materials (including hydrogels, sol-gel-derived organic-inorganic composites and lipid membranes), introduce electroch...
Biofuel cells have been widely used to generate bioelectricity. Early biofuel cells employ a semi-permeable membrane to separate the anodic and cathodic compartments. The impact of different membrane materials and compositions has also been explored. Some membrane materials are employed strictly as membrane separators, while some have gained significant attention in the immobilization of enzyme...
the polysulfone-based membrane has been used in hemodialysis (hd) and it is continuously developed to maintain its sustainability on the subject of biocompatibility. during the polysulfone-based membrane development, several parameters should be considered to improve the membrane performances, such as excellent biocompatibility, appropriate ultrafiltration rate, and effective clearance of the t...
