Vitamins C and B1: Amorphization, Crystallization, and Vitamin Degradation

Mauer L.J., Ismail Y., Arioglu-Tuncil S., Voelker A.L., Purdue University, US

Crystalline ingredient forms of water soluble essential vitamins C and B1 may dissolve or melt during food production, and then re-solidify in crystalline or amorphous forms. This study compared the phase transformations, amorphization, and chemical [...]

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 [...]

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 [...]
