This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

Harvard researchers have used single strand DNA, to self assemble custom designed nano scale structures. Each of the bricks shown to the left is, 25-nanometers on a side, they are composed of ~1,000 ...

Abstract: All optical logic gates has been a prime area of research in the past. Several notable attempts have been made and many designs have been proposed. One of the important aspects in the use of ...

A soft material performs NAND logic with visible light, showing a path toward materials that process information without conventional electronic circuitry. “This project has been part of my scientific ...

Designed and implemented a modified DES encryption model by replacing traditional XOR operations with NAND logic gates.Developed and tested a custom Feistel-based workflow, demonstrating innovation in ...
