Dc conductivity and dielectric spectroscopic for PVA-Ag nanocomposite films The influence of gamma irradiation on the electrical and dielectric properties of AgNO3/ PVA films was investigated. The films were prepared by casting techniques, then irradiated with different gamma doses (25, 50, 75, 100, 125 KGy). The content of the Ag in the PVA film were determined by using atomic absorption spectroscopy (AA), and were found to be 0.4 wt %. The films have been characterized through dielectric spectroscopy

The car has been a mainstay of American culture for about a century. The idea of a car in every garage has been around for almost as long. Teenagers view getting their driver's license as a rite of passage and our cross-country highways support the notion of the Great American Road Trip. We drive our cars everywhere. And after all these years, doing so has become a problem. [1] Over the last century, the Earth's average temperature has risen by 1.4 °F. Over the next century, that average

1. INTRODUCTION Laser tag is a team or individual sport or recreational activity where players attempt to score points by tagging targets, typically with a hand­held infrared­emitting targeting device. Infrared­sensitive targets are commonly worn by each player and are sometimes integrated within the arena in which the game is played. Since its birth in 1979, with the release of the Star Trek Electronic Phasers toy manufactured by the South Bend Electronics brand of Milton Bradley, laser tag has

High Speed Data Transmission of Multi-mode fibers using Orbital Angular Momentum Abstract: The design and fabrication of an optical fiber to support OAM modes for high speed data transmission. Generally OAM modes carry different charge and phase change, so the fiber has to be designed and fabricated in such a way that fiber support different OAM modes A compact low crosstalk multi ring fiber transmitting multiple orbital angular momentum is presented.Multi ring fiber consists of

Lecture 4 Density of States and Fermi Energy Concepts Reading: (Cont’d) Notes and Anderson2 sections 2.8-2.13 Georgia Tech ECE 3080 - Dr. Alan Doolittle How do electrons and holes populate the bands? Density of States Concept In lower level courses, we state that “Quantum Mechanics” tells us that the number of available states in a cubic cm per unit of energy, the density of states, is given by: * * mn 2mn ( E  Ec ) gc (E)  , E  Ec 2 3   gv (E)  m * 2 m * ( Ev  E )

Effect of Point and Line Defects on the Properties of Graphene: A Review Rajasekaran G, Prarthana Narayanan and Avinash Parashar* Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India * Corresponding author: E-Mail: drap1fme@iitr.ac.in, Ph: +91-1332-284801 ABSTRACT New materials with distinctive properties are arising and attracting the scientific community at regular intervals. Stiffness and strength are the important factors in determining

LITERATURE PROJECT CHEM3004 LITHIUM-ION BATTERIES Abstract Technology is striving to keep up with today's society. We continuously require smaller, lighter and more autonomous equipment. The rechargeable lithium ion battery is the most important factor in determining the rate of development of modern day consumer electronics. Perhaps not surprisingly the transport of lithium ions (Li+) remains the preferred technology to achieve this. As a result and for the purpose of this review, only
