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 ABC radio in Australia Australia, officially the Commonwealth of Australia, is a country comprising mainland Australia, the mainland of the Australia (continent), Australian continent, the island of Tasmania and list of islands of Australia, numerous smaller isl ...br> References * Motoike I., 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 (e.g. K+ (potassium ion)) while an anion is a negatively charged ion with more electrons than protons (e.g. Cl− (chloride ion) and OH− (hydroxide ion)). 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 ''monatomic ions'', ''atomic ions'' or ''simple ions'', while ions consisting of two or more atoms are termed polyatomic ions or ''molecular ions''. If only a + or − is present, it indicates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrons
The electron (, or in nuclear reactions) is a subatomic particle with a negative one elementary charge, elementary electric charge. It is a fundamental particle that comprises the ordinary matter that makes up the universe, along with up quark, up and down quark, down quarks. Electrons are extremely lightweight particles that orbit the positively charged atomic nucleus, nucleus of atoms. Their negative charge is balanced by the positive charge of protons in the nucleus, giving atoms their overall electric charge#Charge neutrality, neutral charge. Ordinary matter is composed of atoms, each consisting of a positively charged nucleus surrounded by a number of orbiting electrons equal to the number of protons. The configuration and energy levels of these orbiting electrons determine the chemical properties of an atom. Electrons are bound to the nucleus to different degrees. The outermost or valence electron, valence electrons are the least tightly bound and are responsible for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 computer A billiard-ball computer, a type of conservative logic circuit, is an idealized model of a reversible computing, reversible mechanical computer based on Newtonian dynamics, proposed in 1982 by Edward Fredkin and Tommaso Toffoli.

University Of The West Of England, Bristol
The University of the West of England (also known as UWE Bristol) is a Public university, public research university, located in and around Bristol, England, UK. With more than 39,912 students and 4,300 staff, it is the largest provider of higher education in the South West of England. The institution was known as the Bristol Polytechnic in 1969; 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 Merchant Venturers, 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, Bristol, Arnolfini, Spike Islan ...

New Scientist
''New Scientist'' is a popular science magazine covering all aspects of science and technology. Based in London, it publishes weekly English-language editions in the United Kingdom, the United States and Australia. An editorially separate organisation publishes a monthly Dutch-language edition. First published on 22 November 1956, ''New Scientist'' has been available in online form since 1996. Sold in retail outlets (paper edition) and on subscription (paper and/or online), the magazine covers news, features, reviews and commentary on science, technology and their implications. ''New Scientist'' also publishes speculative articles, ranging from the technical to the philosophical. ''New Scientist'' was acquired by Daily Mail and General Trust (DMGT) in March 2021.

Belousov–Zhabotinsky Reaction
A Belousov–Zhabotinsky reaction, or BZ reaction, is one of a class of reactions that serve as a classical example of non-equilibrium thermodynamics, resulting in the establishment of a nonlinear chemical oscillator. The only common element in these oscillators is the inclusion of bromine and an acid. The reactions are important to theoretical chemistry in that they show that chemical reactions do not have to be dominated by equilibrium thermodynamic behavior. These reactions are far from equilibrium and remain so for a significant length of time and evolve chaotically. In this sense, they provide an interesting chemical model of nonequilibrium biological phenomena; as such, mathematical models and simulations of the BZ reactions themselves are of theoretical interest, showing phenomenon as noise-induced order. An essential aspect of the BZ reaction is its so called "excitability"; under the influence of stimuli, patterns develop in what would otherwise be a perfectly quie ...

Robot
A robot is a machine—especially one Computer program, programmable by a computer—capable of carrying out a complex series of actions Automation, automatically. A robot can be guided by an external control device, or the robot control, control may be embedded within. Robots may be constructed to evoke Humanoid robot, human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics. Robots can be autonomous robot, autonomous or semi-autonomous and range from humanoids such as Honda's ''Advanced Step in Innovative Mobility'' (ASIMO) and TOSY's ''TOSY Ping Pong Playing Robot'' (TOPIO) to industrial robots, robot-assisted surgery, medical operating robots, patient assist robots, dog therapy robots, collectively programmed Swarm robotics, ''swarm'' robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic Nanorobotics, nanorobots.

Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is Australia’s principal public service broadcaster. It is funded primarily by grants from the federal government and is administered by a government-appointed board of directors. The ABC is a publicly-owned statutory organisation that is politically independent and accountable; for example, through its production of annual reports, and is bound by provisions contained within the Public Interest Disclosure Act 2013 and the Public Governance, Performance and Accountability Act 2013, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an Act of Federal Parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A ...
