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 [...]

Graphene-Based Nanostructures for Advanced Sensing Applications

Abdul-Wahed A., Serry M., The American University in Cairo, EG

New nanostructured Schottky junctions based on graphene/platinum grown on different substrates are fabricated and investigated. The integration of graphene layer (s) on regular M-S junctions was only possible by using an ALD grown platinum thin [...]

Solar Energy System Prototype with a Maximum Power Point Tracking (MPPT)

Abdelmoaty A.A., Helmy A., Rezk A.A., Ismail Y., The American University in Cairo, EG

The paper shows the design and implementation of a novel power management unit that combines (mixes) several power harvesting sources and delivers (routes) the power to the working load and the battery. The system can [...]

Novel Aluminum-CNT composites for structural applications

Esawi A.M.K., Salama E., The American University in Cairo, EG

The latest enhancements in the mechanical behaviour of Al-CNT composites achieved by the research group are presented : an increase in tensile strength, indentation hardness and Young’s modulus of 69%, 72% and 23%, respectively. The [...]

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 [...]
