Introduction Photodiode play important roles in optical communication systems nowadays. In this field, fiber optic cable is used as an information signal transmission medium between the light sources, sensors and photodiode. Many materials can provided to make the photodiode substrate in order to produce the detector to be used in application that require higher bandwidth and long distance tran...

The metal-catalyzed polymerization of simple olefins, such as ethylene and propylene, has been one of the transformational discoveries in chemistry of the 20th century. It is difficult to imagine today’s civilization without ubiquitous plastics, such as polyethylene and related polymers. Although often attributed to Karl Ziegler and Giulio Natta, the winners of the 1963 Nobel Prize in Chemistry...

Titania supported vanadium oxide catalysts have been demonstrated to be very efficient catalysts for the selective reduction of NOx with NH3 and have found widespread industrial application for the control of NOx emissions from stationary sources (1). Characterization studies have demonstrated that supported vanadium oxide catalysts consist of a two-dimensional metal oxide overlayer on the oxid...

A novel template synthesis of bone-shaped (dumbbell-shaped, dogbone-shaped) nanomaterials is demonstrated. Porous anodic alumina (PAA) templates with uniform nanochannels were fabricated using a four-step anodization process and used to form bone-shaped carbon nanostructures with stem and end diameters and lengths of 40 nm, 70 nm, and 5 μm, respectively. These nanomaterials, which we refer to a...

In order to study the activity of the different desaturases present in the pheromone biosynthetic pathway of the Egyptian armyworm, Spodoptera littoralis, we report the preparation, characterization and the desaturase inhibition of a series of monoand gemdifluorinated analogues of myristic acid with halogen substitution at C8-C11 positions of the aliphatic chain via specifically positioned dith...
