Vinylene carbonate (VC) or 1,3-dioxol-2-one, is the simplest unsaturated cyclic carbonic acid ester. Vinylene carbonate can also be thought of as the cyclic carbonate of the hypothetical ( Z )-ethene-1,2-diol.
In chemistry, vinylene (also ethenylene or 1,2-ethenediyl) [1] is a divalent functional group (a part of a molecule) [2] with formula −CH=CH−; [3] namely, two carbons, each connected to the other by a double bond, to an hydrogen atom by a single bond, and to the rest of the molecule by another single bond.
Superconcentrated electrolytes, also known as water-in-salt or solvent-in-salt liquids, usually refer to chemical systems, which are liquid near room temperature and consist of a solvent-to-dissoved salt in a molar ratio near or smaller than ca. 4-8, i.e. where all solvent molecules are coordinated to cations, and no free solvent molecules remain.

APCI is a soft ionization method similar to chemical ionization where primary ions are produced on a solvent spray. [4] The main usage of APCI is for polar and relatively less polar thermally stable compounds with molecular weight less than 1500 Da. [ 5 ] The application of APCI with HPLC has gained a large popularity in trace analysis ...
Mayo Clinic Proceedings is a monthly peer-reviewed medical journal published by Elsevier and sponsored by the Mayo Clinic. It covers the field of general internal medicine. The journal was established in 1926 as the Proceedings of the Staff Meetings of the Mayo Clinic and obtained its current name in 1964.
Poly(p-phenylene vinylene) (PPV, or polyphenylene vinylene) is a conducting polymer of the rigid-rod polymer family. PPV is the only polymer of this type that can be processed into a highly ordered crystalline thin film. PPV and its derivatives are electrically conducting upon doping.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
A review of websites promoting nasal sprays containing colloidal silver suggested that information about silver-containing nasal sprays on the Internet is misleading and inaccurate. [85] Colloidal silver is also sold in some topical cosmetics , as well as some toothpastes, which are regulated by the FDA as cosmetics (other than drug ingredients ...
