Quantum dots known as nanocrystals is a semiconductor whose excitons are confined in all three spatial dimensions. As a result, they have properties that are between those of bulk semiconductors and those of discrete molecules which are crystals composed of periodic groups of II-VI, III-V, or IV-VI materials. Semiconductors are a cornerstone of the modern electronics industry and make possible applications such as the Light Emitting Diode and personal computer

INTRODUCTION
Decimal arithmetic has found promising uses in thefinancial and commercial applications. This is due tothe precise calculations required in these applications asoppose to binary arithmetic where some of decimalfractions can not be represented precisely . Thesoftware implementation of decimal arithmeticeliminates these conversion errors, but it is typically100 to 1000 times slower than binary arithmetic. Thisattracts the attention of hardware designers to add adecimal arithmetic unit to CPUs to perform decimalcalculation ....etc

Abstract
In their article, Is the Brain a Quantum Computer,? Litt, Eliasmith, Kroon, Weinstein, and Thagard (2006) criticize the Penrose“Hameroff Orch OR quantum computational model of consciousness, arguing instead for neurocomputation as an explanation for mental phenomena. Here I clarify and defend Orch OR, show how Orch OR and neurocomputation are compatible, and question whether neurocomputation alone can physiologically account for coherent gamma synchrony EEG, a candidate for the neural correlate of consciousness. Orch OR is bas ....etc

Nonvolatile Memory Characteristics of NMOSFET with Ag Nanocrystals Synthesized via a Thermal Decomposition Process for Uniform Device Distribution
Abstract—
This paper presents nonvolatile memory characteristics using Ag nanocrystals (NCs) formed by a thermal decomposition and size-selective precipitation technique for Flash memory application. In the NC formation process, the size of NCs and the space NC-to-NC were precisely controlled by a size-selective precipitation technique and the length of the self-assembled monolayer surrou ....etc

Evolution of Quantum Automata
• Quantum events cannot be simulated in classical computers in feasible time.
• So it was needed to formalize the quantum computers.
• Quantum automata are the basic model for the quantum computers.
• Quantum automata are built due to the problems of classical computers with certain mathematical problems.
Classical Computational Unit (Bits)
• A building block of classical computational devices is a ....etc

Quantum Wells, Quantum Wire, and Quantum Dots




I'd like to explore the material known as Wellstone. There are some interesting aspects to this material, and it is written about in Hacking Matter by Will McCarthy. It is not necessarily nanotechnology, so much as it is quantum level materials and bio-molecular control over nano sized or meso-sized particles.
We will return to the world of Nanotechnology and DNA computing shortly, for now - let's talk about Wellstone.
