A CMOS Lab-On-A-Chip For Neuron Monitoring And Stimulation

Ghallab Y.H., Ismail Y., Center of Nano Electronics and Devices (CND) at American University in Cairo/ Zewail City of Science and Technology, Cairo, Egypt, EG

Many tools have been established to monitor neural activity such as patch pipettes and microelectrodes, which are electrolyte filled glass tubes used to create intracellular contacts by rupturing the cell membrane and directly measuring the [...]

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 [...]

A Study of the Effect of Al2O3 Nanoparticles on the Cure behavior of Bisphenol A Epoxy Resin

Halim S.F., National Institute for standards, EG

Epoxy resins based composites are used as laminates for printed circuits boards, aerospace, ballistic and engineering hardware components, automotive parts, electrical components and rehabilitation products. However, some of its interior characteristics such as thermal stability, [...]

All-solid-state polymer electrolyte with plastic crystal materials for rechargeable

Sheha E., Benha University, EG

In this paper, we report the synthesis and properties of a series of composite polymer electrolytes formed by dispersion of a non-ionic organic plastic material succinonitrile (SN) into poly(vinyl alchole) complexed with magnesium acid salt. [...]

Electrosynthesis of Intrinsically Conducting Polymers/Silicon Nanocomposites: Formation Mechanism and Optical Properties

Harraz F.A., Salem A.M., Central Metallurgical R&D Institute (CMRDI), EG

When a silicon wafer is subjected to electrochemical etching in fluoride-based solution, silicon surface develops pores, often called porous silicon (PSi). A variety of pore sizes ranging from a few nanometers up to a few [...]

Carbon coated FeRu and CoRu nanomagnets and their potential for medical application

El-Gendy A.A., Hampel S., Leonhardt A., Khavrus V.O., Büchner B., Klingeler R., National Institute for standards, EG

This work presents a novel synthesis procedure for carbon-coated magnetic nanoparticles and their detailed characterization regarding structure, morphology, and magnetic properties. To be specific, the high pressure chemical vapour deposition technique (HPCVD) has been applied [...]

Poly(caprolactone)–Pluronic– poly(caprolactone) amphiphilic copolymer nanoparticles for controlled 5-Fluorouracil delivery

Mohamed M.M., Faculty of Allied Medical Science, Pharos University in Alexandria, EG

5-Fluorouracil (5-FU), a pyrimidine analogue that interferes with thymidylate synthesis, has a broad spectrum of activity against solid tumors. However, 5-FU has limitations that include a short biological half-life, incomplete and non-uniform oral absorption, toxic [...]

A Fully Symmetric and Completly Decoupled MEMS-SOI Gyroscope

Sharaf A., Sedky S., Serry M., Elshurafa A., Ashour M., Habib S.E.-D., American University in Cairo, EG

Gyroscopes are sensors that measure rotation rate and are extremely important in many applications such as navigation and vehicle stability control. Despite being manufactured in many technologies in various shapes and sizes, micro-electromechanical (MEMS) gyroscopes [...]
