An ion (/ ˈaɪ.ɒn, - ən /) [1] 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 ...
Defining the Internet of things as "simply the point in time when more 'things or objects' were connected to the Internet than people", Cisco Systems estimated that the IoT was "born" between 2008 and 2009, with the things/people ratio growing from 0.08 in 2003 to 1.84 in 2010. [37]
In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...
Ion Television. Ion Television (referred to on-air as simply Ion) is an American broadcast television network and FAST television channel owned by the Scripps Networks subsidiary of the E. W. Scripps Company. The network first began broadcasting on August 31, 1998, as Pax TV, focusing primarily on family-oriented entertainment programming.
The industrial internet of things (IIoT) refers to interconnected sensors, instruments, and other devices networked together with computers' industrial applications, including manufacturing and energy management. This connectivity allows for data collection, exchange, and analysis, potentially facilitating improvements in productivity and ...
A prototype of a xenon ion engine being tested at NASA's Jet Propulsion Laboratory (2005) An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms.
The study of ion channels often involves biophysics, electrophysiology, and pharmacology, while using techniques including voltage clamp, patch clamp, immunohistochemistry, X-ray crystallography, fluoroscopy, and RT-PCR. Their classification as molecules is referred to as channelomics.
The carbonite ion is an anion with the chemical formula C O 2− 2.This divalent anion forms by deprotonation of carbonous acid (C(OH) 2). Alkali metal salts of carbonous acid, Li 2 CO 2 (lithium carbonite), K 2 CO 2 (potassium carbonite), Rb 2 CO 2 (rubidium carbonite) and Cs 2 CO 2 (caesium carbonite), have been observed at 15 K.
