MODERN ZINC OXIDE SURGE ARRESTER



Introduction
The most important matter in a
power system is how to handle a fault condition. In power
system networks we have to maintain the voltage, current
and other network parameters at a specified value .
If an abnormal condition is occurred we
must take precaution against the abnormality to protect
the succeeding elements connected to the network.There
are many modern technique to clear the over voltage
condition due to surge fault ....etc

green synthesis of nanoparticles from plant extract ppt

Abstract
Metallic nanoparticles are being utilized in every phase of science along with engineering including medical fields and are still charming the scientists to explore new dimensions for their respective worth which is generally attributed to their corresponding small sizes. The up-and-coming researches have proven their antimicrobial significance. Among several noble metal nanoparticles, silver nanoparticles have attained a special focus. Conventionally silver nanoparticles are syn ....etc

Biodiesel production from Jatropha caucus oil in a batch reactor using zinc oxide as catalyst



INTRODUCTION

Majority of the world energy needs are supplied through
petrochemical sources, coal, and natural gases, with the
exception of hydroelectricity and nuclear energy. Of all
these sources that are finite, the current usage rates will
be consumed shortly. Non-renewable energy sources
such as petroleum are related to several drawbacks
including; increase green house emission ....etc

A SONOS memory cell is formed from a standard polysilicon NMOS transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thi ....etc
