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 [...]

Synthesis of conductive elastic film and conductive fabric based on crosslinked carboxymethyl starch-AgNPs composite

El-Sheikh M.A., National Research Centre, Egypt, EG

The current work is developing a novel, facile and eco-friendly method for synthesis of highly concentrated silver nanoparticles (AgNPs) using AgNO3 as a precursor, the eco-friendly carboxymethyl starch (CMS) polymer as both reducing and stabilizing [...]

Inhalable Stimuli-Responsive Theranostic Nanoparticles for Cancer in Deep Lung Tissue

Abbas Y.H., American University in Cairo, EG

Lung cancer is the deadliest solid tumour among all types of cancer. Despite advances in surgery and drug discovery lung cancer remains difficult to treat. This is a result of unavoidable exposure to carcinogens, poor [...]

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 [...]

Ultra-Low Power Node for Body Sensor Network

Yahya E., Ismail M., Ismail Y., Ismail M., Ismail Y., American University in Cairo/ Zewail City of Science and Technology, EG

Medical electronics, especially implanted devices, are operated in harsh and unstable operating conditions in which these systems must operate correctly. Medical electronics are usually powered using batteries and/or energy harvesters. This implies that they must [...]

Drain Current Model for Thin Body Undoped and Lightly Doped Double-Gate MOSFETs

Abd Elhamid H., Ineguez B., Ismail Y., Deen MJ., Zewail City of Science and Technology, EG

We developed new compact models that include the QM effects on electrical properties such as the surface potential, and drain current. The models were used to study the impact of subband engineering and holes/electrons IMREF [...]
