Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are isoelectronic, while CH 3 COCH 3 and CH 3 N = NCH 3 are ...
In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study [5] or a database is screened for structural analogs of a lead compound. [6] Chemical analogues of illegal drugs are developed and sold in
Although food engineering is a relatively recent and evolving field of study, it is based on long-established concepts and activities. [1] The traditional focus of food engineering was preservation, which involved stabilizing and sterilizing foods, preventing spoilage, and preserving nutrients in food for prolonged periods of time. [5]
Food storage and preservation is a key component of food engineering processes and relies heavily on biological engineering to understand and manipulate the organisms involved. Note that the above food safety processes such as pasteurization and sterilization destroy the microorganisms that also contribute to deterioration of food products ...
Biological engineering or bioengineering is the application of principles of biology and the tools of engineering to create usable, tangible, economically viable products. [1] Biological engineering employs knowledge and expertise from a number of pure and applied sciences, [2] such as mass and heat transfer, kinetics, biocatalysts ...

In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]
For example. LiNO and BeNO bear Li + NO − and Be + NO − ionic form. [4] [5] The adoption of linear vs bent bonding can be analyzed with the Enemark-Feltham notation. [6] In their framework, the factor that determines the bent vs linear NO ligands is the electron count in the metal-N-O π system. Complexes more than 6 electrons in the system ...
