The structure of the complex of sodium (Na +) and the antibiotic monensin A Structure of a potassium complex of a crown ether, a synthetic ionophore-ion complex. Biological activities of metal ion-binding compounds can be changed in response to the increment of the metal concentration, and based on the latter compounds can be classified as "metal ionophores", "metal chelators" or "metal ...
The Ion building (pictured in December 2020) was converted from a former Sears store and serves as the Ion District's central hub.. The Ion is a 266,000-square-foot (24,700 m 2), six-level building on Main Street in what was formerly a four-story Sears department store built in 1939 and closed in 2018. [12]
Secondary ion mass spectrometry (SIMS) is a method very similar to FAB in that a beam of particles is fired against the surface of a sample in order to cause sputtering, in which the molecules of the sample ionize and leave the surface, thus allowing for the ions or the sample to be analyzed. The primary difference is that in SIMS, an ion beam ...
For example, NaCl can be described as close-packed chloride ions (in a face-centered cubic lattice) with sodium ions in the octahedral holes. After the development of X-ray crystallography as a tool for determining crystal structures, many laboratories built models based on spheres.
Electron capture ionization (ECI) is the ionization of a gas phase atom or molecule by attachment of an electron to create an ion of the form A −•.The reaction is + where the M over the arrow denotes that to conserve energy and momentum a third body is required (the molecularity of the reaction is three).
A single prototyping platform can provide verification for hardware, firmware, and application software design functionality before the first silicon pass. [ 3 ] Time-to-market (TTM) is reduced from FPGA prototyping: In today's technological driven society, new products are introduced rapidly, and failing to have a product ready at a given ...
Ion interaction chromatography (ion-pair chromatography) is a laboratory technique for separating ions with chromatography. In this technique ions are mixed with ion pairing reagents (IPR). [1] The analyte combines with its reciprocal ion in the IPR, this corresponds to retention time. Often organic salts are selected to pair with solute(s).
