Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member

AN OVERVIEW OF THE Shed: This shed was set up in Feb. 1976 by Railway Electrification Organization as a part of Tundla – Delhi electrification scheme and was designed to home 50 electric locomotives at an initial cost of 1.5 crore. The prime objective of setting up this shed was to maintain Electric locomotives required for hauling important mail/express trains on Delhi – Howrah section. The initial holding of the shed was 34‚ all of which were WAM4. At present‚ holding has increased to 138

Unit-II: MOS/BiCMOS Process Technology and Integration Introduction BiCMOS = CMOS + Bipolar (BJT) structures on the same substrate. Advantanges of CMOS device: 1. Low Power 2. High digital IC density. Advantages of Bipolar transistors: 1. Ability to deliver large drive currents 2. Capability to rapidly charge heavy loads. The implementation of digital bipolar circuits with emitter-coupled logic (ECL) gates permits small logic swings and excellent noise immunity

A transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (EMF)‚ or "voltage"‚ in the secondary winding In electrical engineering‚ two conductors are referred to as mutual-inductively coupled or magnetically coupled [1] when

power every 18 months as electronic devices shrink and more logic is packed into every chip.Yet even Moore’s Law will run out of momentum one day as the size of individual bits approaches the dimension of atoms; this has been called the end of the silicon road map. For this reason and also to enhance the multifunctionality of devices (for example‚ carrying out processing and data storage on the same chip)‚ investigators have been eager to exploit another property of the electron—a characteristic known

Konèar PowerTransformers Ltd. A Joint Venture of Siemens and Konèar STRAY LOSSES HOW TO REDUCE THEM AND WHY? KPT-OIPT 013E‚ Published 02.2000. Generally‚ there is a simplified understanding that the socalled load losses in a transformer (load losses‚ PL ) depend on the ohmic resistance of the windings. This is only partly true‚ as the losses arising from magnetic leakage flux in various metal parts of a transformer constitute a significant part of the total losses. This component

1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose
