Blobotics
Blobotics is a term describing research into chemical-based computer processors based on ions rather than electrons. Andrew Adamatzky, a computer scientist at the University of the West of England, Bristol used the term in an article in ''New Scientist'' March 28, 200 The aim is to create 'liquid logic gates' which would be 'infinitely reconfigurable and self-healing'. The process relies on the Belousov–Zhabotinsky reaction, a repeating cycle of three separate sets of reactions. Such a processor could form the basis of a robot which, using artificial sensors, interact with its surroundings in a way which mimics living creatures. The coining of the term was featured by Australian Broadcasting Corporation, ABC radio in Australia] References * Motoike I., Andrew Adamatzky, Adamatzky A.

Ions
An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is a negatively charged ion with more electrons than protons. Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron ...

Electrons
The electron (, or in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum ( spin) of a half-integer value, expressed in units of the reduced Planck constant, . Being fermions, no two electrons can occupy the same quantum state, per the Pauli exclusion principle. Like all elementary particles, electrons exhibit properties of both particles and waves: They can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer ...

Andrew Adamatzky
Andrew Adamatzky is a British computer scientist, who is a Director of the Unconventional Computing Laboratory and Professor in Unconventional Computing at the Department of Computer Science and Creative Technology, University of the West of England, Bristol, United Kingdom. Adamatzky is known for his research in unconventional computing. In particular, he has worked on chemical computers using reaction–diffusion processes. He has used slime moulds to plan potential routes for roadway systems and as components of nanorobotic systems, and discovered that they seek out valerian tablets, promoted as a herbal sedative, in preference to nutrients. He has also shown that the billiard balls in billiard-ball computers may be replaced by soldier crabs. Adamatzky is a director of the Unconventional Computing Laboratory, founding Editor-in-Chief of the ''Journal of Cellular Automata'' (OCP Science, 2005–) and the ''International Journal of Unconventional Computing'' (OCP Science, 20 ...

University Of The West Of England, Bristol
The University of the West of England (also known as UWE Bristol) is a public research university, located in and around Bristol, England. The institution was know as the Bristol Polytechnic in 1970; it received university status in 1992 and became the University of the West of England, Bristol. In common with the University of Bristol and University of Bath, it can trace its origins to the Merchant Venturers' Technical College, founded as a school in 1595 by the Society of Merchant Venturers. UWE Bristol is made up of several campuses in Greater Bristol. Frenchay Campus is the largest campus in terms of student numbers, as most of its courses are based there. City campus provides courses in the creative and cultural industries, and is made up of Bower Ashton Studios, Arnolfini, Spike Island, and Watershed. The institution is affiliated with the Bristol Old Vic Theatre School and validates its higher education courses. Frenchay Campus and Glenside Campus are home to most ...
