ABSTRACT
A surface micro machined capacitive switch has been designed and fabricated on a glass substrate. The switch is constructed of a thin metallic membrane crossing over an electroplated coplanar wave-guide transmission line. The electrostatic actuation is utilized as the switching mechanism. The actuation voltage is around 50V. The switch showed low insertion loss of 0.1 dB at 10 GHz and 0.4 dB at 25 dB, and isolation of 15dB at 20GHz. This device offers a potential application in tel ....etc

Abstract
A tunable micro-electromechanical systems integrated inductor with a large-displacement electro-thermal actuator is discussed here. Based on a transformer configuration, the inductance of a spiral inductor is tuned by controlling the relative position of a magnetically coupled short-circuited loop. Theoretical studies are backed by a variety of fabricated and measured tunable inductors that show a 2 : 1 inductance tuning ratio over a wide frequency range of approximately 25 GHz. In addition, the maximum and minimum quality fa ....etc

ABSTRACT
Imagine a supercomputer no bigger than a human cell. Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. Imagine attaining immortality by drinking a medicine. These are just a few products expected from Nanotechnology.
Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed nanoscopic robot arms; Nanotechnology proposes the construction of novel molecular devices possessing extraordin ....etc

MEMS SWITCHES

INTRODUCTION

Compound solid state switches such as GaAs MESFETs and PIN diodes are widely used in microwave and millimeter wave integrated circuits (MMICs) for telecommunications applications including signal routing, impedance matching networks, and adjustable gain amplifiers. However, these solid-state switches have a large insertion loss (typically 1 dB) in the on state and poor electrical isolation in the off state. The recent developments of micro-electro-mechanical systems (MEMS ....etc

Introduction

-What is an electroplating sludge?
It s a residual, semi solid waste of electroplating process containing hazardous metals.
-Normally EP sludge disposal is done by incineration, land filling and effluent disposal to water bodies.
-Toxic gases are produced during incineration, Hazardous metals are mixed with water and soil in land filling process causing water and soil pollution. These are the m ....etc

Abstract

Excessive concentrations of metals in industrial effluents may adversely affect the performance of sewage purification works. Although there is existing technology for treating these effluents, it has not found wide application due to costly equipment and chemicals and the absence of sufficient space on most plants. In this paper the feasibility of removing these metals from dilute solutions by electrolytic precipitation using a particulate electrode is investigat ....etc
