Owing to their novel applications as high gate dielectric materials, we aim to explore some important properties of the lanthanum doped Bi1.5Zn0.92Nb1.5O6.92 (La-BZN) pyrochlore ceramics. Particularly, we plan to investigate the temperature effects on the structural properties of the La-BZN in the temperature range of 300-473 K by the X-ray...

The fiber Bragg grating of an OADM has to be temperature compensated using negative expanding temperature coefficient. Temperature compensation package of FBG and two circulators will be used to design one channel add-drop multiplexer. Optical testing of the multiplexer will be done using optical spectrum analyzer.

Fiber bragg grating is an in fiber optical passive device used in communication and sensing applications. It is a band rejection filter used to reflect back a band the optical spectrum and allow the rest of the signal to pass through. This is an important filter device in optical communication networks and sidelobes should be as small as possible...

Owing to its smart properties as a phase change memory device, here in this project, the Sb2Te3 thin films will be deposited onto a photovoltaic Se substrate. The Se/Sb2Te3 interface will be characterized by means of X-ray diffraction, scanning electron microscopy, energy dispersion X-ray analysis, optical spectroscopy, dark and photo illuminated...

Certain phytochemicals can cure several types of diseases, and may play an important role in pharmacology as natural supplements to control various diseases as fast and reliable alternatives. Many synthetic drugs cause severe side effects that are not acceptable. Natural products with therapeutic properties have been used since antiquity in...

Unique properties of stem cells self-renewal as well as differentiation into multiple cell types make them an attractive approach for developing clinical therapies for human neurodegenerative disorders. It is demonstrated that postnatal central nervous system (CNS) harbors adult stem cells called neural stem cells (NSCs). These cells are isolated...

Conducting polymers (CPs) (like polypyrrole, polythiophene, polyaniline, …) have been applied in the design of catalytic sensors as immobilization matrixes, signal transduction systems, and analyte-recognizing components. Nanostructured conducting polymers featuring high surface area, small dimensions, and unique physical properties that could be...

Many semiconductors have been extensively studied due to their suitable value band gap and the very high electron mobility. Despite of their wide applications in device manufacturing, the utilizations of semiconductors in PEC is limited by the following facts: they corrode with photocurrent (anodic corrosion). Such degradation can be lowered by...

In this work, cupric oxide (CuO) thin film electrodes will be prepared using a simple and inexpensive electrodeposition method on the fluorine- doped tin oxide (FTO)/glass substrates. Several parameters will be controlled to enhance the conversion efficiency and stability of the prepared films under photoelectrochemical (PEC) conditions. These...

To survey the incidence of iatrogenic failure in root canal treated teeth in Palestinian population of the west bank and Jerusalem, and to correlate the prevalence of that failure with variation of tooth location and anatomical morphology between anterior, premolar and molar teeth, as determined by digital panoramic radiograph collected from all...
