Alginate/Montmorillonite nancomposites for the delivery of curcumin

Ramadan A.R., Ahmed M., The American University in Cairo, EG

Curcumin is a well-known traditional medicine with anti-inflammatory and antioxidant properties. Its pharmacological mechanism of action and safety have been studied to investigate its use in clinical and therapeutic applications. However, its low water solubility [...]

Carbon Nanotube Bucky Papers with Tailored Porosity for Filtration Applications

Esawi A.M.K., Ramadan A.R., ElNur R., The American University in Cairo, EG

In this work, Carbon Nanotube Buckypapers (CNT-BPs) were prepared using vacuum filtration. Morphology and pore size distribution were investigated using scanning electron microscopy (SEM) and nitrogen gas adsorption. The prepared BPs were subsequently exposed to [...]

Cellulose Acetate Nanocomposite Membranes for Water Desalination Applications

Ramadan A.R., Esawi A.M.K., El Badawi N., Mahmoud M., The American University in Cairo, EG

Interest in the use of membranes in water desalination applications has been increasingly developing due to their numerous advantages. Among the various desalination technologies, ‎Reverse Osmosis (RO) membrane processes are steadily becoming more reliable and [...]

Ethylene Vinyl Acetate – Cloisite Nanocomposite Membranes and their Gas Separation Behavior

Ramadan A.R., Esawi A.M.K., Abdel-Hafiz A., Charmette C., Ayral A., The American University in Cairo, EG

The current work aims at understanding the correlation between EVA-montmorillonite clay nanocomposite membrane morphology and gas permeation properties. 5wt% of Cloisite-20A and 30B organoclays were added to EVA having 18wt% vinyl acetate. Nanocomposite membranes were [...]
