leaning Ions - The Secret Behind Nano Technology

** Pros over competition: Low cost, no yearly maintenance, simple installation,
and a system for delivering airborne hydro peroxides, super oxide ions and hydroxide ions that travel throughout the house or office providing 24-hour protection against airborne mold, bacteria, viruses, odors and VOC?s. The NanoO2 chamber cell also acts as a UVC/HE germicidal lamp and treats the air that passes by it. For faster and improved results in areas of high contamination an extremely quiet 2 speed fan ....etc

A Novel Secure Communication Protocol for Ad Hoc networks
Abstract
An ad hoc network is a self organized entity with a number of mobile nodes without any centralized access point and also there is a topology control problem which leads to high power consumption and no security, while routing the packets between mobile hosts. Authentication is one of the important security requirements of a communication network. The common authentication schemes are not applicable in Ad hoc networks.
In this paper, we propose a s ....etc

Abstract:
A nanometer is one billionth of a meter. If you blew up a baseball to the size of the earth, the atoms would become visible, about the size of grapes. Some 3- 4 atoms fit lined up inside a nanometer. Nanotechnology is about building things atom by atom, molecule by molecule. The trick is to be able to manipulate atoms individually, and place them where you wish on a structure.

Nanotechnology uses well known physical properties of atoms and molecules to make novel devices with ex ....etc

ABSTRACT
Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc video recording format jointly developed by nine leading consumer electronics companies. The format was developed to enable recording, rewriting and playback of high-definition video (HDTV). Blu-ray makes it possible to record over 2 hours of digital high-definition video (HDTV) or more than 13 hours of standard-definition video (SDTV/VHS picture quality) on a 27GB disc. There are also plans for higher capacity discs that are expe ....etc

ABSTRACT

Low-k dielectrics are the very latest path breaking development in the field of Integrated Electronics. It is well on its way replacing the Al / SiO2 interconnects with the help of copper in CMOS fabrication of IC Chips. The CMOS technology has an in-built coupling capacitance which increases the time delay, thereby reducing associated processing speeds. This was compensated by reducing the thickness of the Al / SiO2 interconnects. There is a limit to the reduction in t ....etc
