This review reports the recent significant progress for achieving the synthesis of various types of polymer-based nanocomposites and understanding of the basic principle which determine their optical, electronic and magnetic properties. Some of the polymeric nanocomposite materials show remarkable electrical as well as optical properties regarding towards interest for applications in OLEDs. Nanoparticles which are basically inorganic, plays important role in the opto-electronic field. A nanoparticle with conjugate polymer matrix makes polymer nanocomposite and that nanocomposite used as an active emissive layer between the structures of optoelectronic device like OLEDs, OPVs etc. Application of such polymeric nanocomposite materials are discussed in this present communication with their success and failure, towards their optical as well as electrical properties in the fabrication of OLEDs.

Abstract The double perovskite structure is interesting for many researches in various fields of physics and their technological applications. The LaPbFeTiO6 (LPFTO) compound is a very important for many technologies because it has dielectric and electrical properties. It has made an attractive semiconductor material for the electronic field, such as the realization of filters or capacitors. In this work, LaPbFeTiO6 was prepared by the sol-gel method.The structural, morphological and electrical properties of this sample were studied using different techniques. X-ray diffraction analysis, the sample crystallized in the rhombohedral system with space group R C. The surface of the sample and the average grain size were examined by scanning electron microscope (SEM). The electrical conductivity and dielectric characterizations were studied as a function of frequency and temperature (200-380K) by impedance spectroscopy. Indeed, the dielectric constant increases with increasing temperature. The AC conductivity obeys the Jonscher power law. The activation energy obtained from the complex impedance and the conductivity are close. The frequency dependence of the electrical impedance shows the existence of a relaxation phenomenon.

Among the various applications of carbon nanotubes (CNTs) that have been investigated since the discovery of their exceptional potential in the electronic field, great interest has been directed towards the creation of carbon-based materials capable of replacing Indium Tin Oxide (ITO) as a transparent electrode. Such transparent conductive films find application in touch panels, LCD screens, OLED displays, photovoltaic cells, and many others. This review presents a collection of techniques that have been proposed during the last decade for the modeling of carbon nanotube-based materials by means of equivalent electrical networks. These networks represent the electrical properties of CNT-based conductive thin films in a way that can be easily included in circuit simulators for the simulation-assisted design of the different devices under static and dynamic conditions.

This study examined the impact of a live, interactive electronic field trip (EFT), called Scientist Online: The Science of Mosquitoes via the Streaming Science platform and Skype in the Classroom network for connecting university entomologists with middle and high school youth around the world. More than 150 students viewed the program, and 60 answered post-quantitative and qualitative questions regarding their perceptions of the EFT and knowledge related to mosquitoes. Students reported an increased knowledge about mosquitoes, mosquito-borne illness, mosquito-borne illness prevention and protection, entomology and related careers, and the mosquito life-cycle. Future research should determine how interactive, synchronous video programs with scientists can impact participants’ behavior intentions, specifically for making lifestyle choices based in science, as well as decision-making for improving their health and the planet.

The field programmable photonic gate array (FPPGA) is an integrated photonic device/subsystem that operates similarly to a field programmable gate array in electronics. It is a set of programmable photonics analogue blocks (PPABs) and of reconfigurable photonic interconnects (RPIs) implemented over a photonic chip. The PPABs provide the building blocks for implementing basic optical analogue operations (reconfigurable/independent power splitting and phase shifting). Broadly they enable reconfigurable processing just like configurable logic elements (CLE) or programmable logic blocks (PLBs) carry digital operations in electronic FPGAs or configurable analogue blocks (CABs) carry analogue operations in electronic field programmable analogue arrays (FPAAs). Reconfigurable interconnections between PPABs are provided by the RPIs. This chapter presents basic principles of integrated FPPGAs. It describes their main building blocks and discusses alternatives for their high-level layouts, design flow, technology mapping and physical implementation. Finally, it shows that waveguide meshes lead naturally to a compact solution.
