New polyoxadiazole-based supported ionic liquid membranes were designed and elaborated for the first time to be used as a middle- high-temperature polymer electrolyte membrane fuel cell application. The proposed molecular design combined hydroxyl-functionalized sulfonated polyoxadiazole, hydrophilic polyvinylpyrrolidone specific protic liquid, thus allowing elaboration of with remarkable physic...
Polyacrylonitril (PAN)-supported chitosan (CS) nanocomposite membranes were prepared by cross-linking the CS with 3-aminopropyl-triethoxysilane (APTEOS) via sol-gel method. Pervaporative performances of the CS-SiO2/PAN membrane for dehydration of aqueous alcohol solutions were investigated. From SEM cross-sectional images of the membrane, the spongy pores and the finger-like pores we...
Background: Polyamines present in human body are frequently considered as markers of occurrence of cancer. Therefore, the availability of simple and efficient method for determination of their level in body liquids and tissues is of some interest. Methods: Supported liquid membrane technology coupled with HPLC seems to be an appropriate technique to follow the level of polyamines in human blood...
