Translations of "polymer chemistry" into Chinese in sentences, translation memory Declension Stem Match words all exact any The term "polyol" can have a slightly different meaning in food science and polymer chemistry. 多元醇(英语:Polyol)是指拥有多个羟基的醇,在食品科学和高分子化学中有重要的...
noun ,Chemistry. a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller molecules with the elimination of water, alcohol, or the like, as nylon. ...
The word polymer comes from the Greek prefixpoly-, which means "many," and the suffix -mer, which means "parts." The word was coined by Swedish chemist Jons Jacob Berzelius (1779–1848) in 1833, although with a slightly different meaning from the modern definition. The modern understanding ...
After minimum, ηsp values less than those of the control solution suggest a less amount of the polyanion in excess, that meaning a higher polyanion amount included in PEC structure. The conductivity values increase linearly with the increasing of the unit molar ratio [PA]/[PC], until the ...
flavors may be encoded by adding additional fingerprint components. Contrary to homopolymer fingerprints, copolymer fingerprints may not be interpretable (e.g., the composition-weighted sum of the fingerprint component “length of largest side-chain” of two homopolymers has no physical meaning). ...
A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic.
In the last two decades, numerous catalytic methods have become woven into the fabric of green and sustainable chemistry. In order to qualitatively evaluate and construct a tangible meaning for sustainable processes in polymer chemistry, this perspective outlines ten desirable attributes of homogeneous ...
polymer research has lagged in terms of constructing open databases available for data-driven research. The primary objective in the development of RadonPy was to use it to create a systematically designed polymer property database. In the early days of MI in inorganic chemistry, the development ...
This interlinking of many units has given the polymer its name, poly meaning 'many' and mer meaning 'part'( in Greek). As an example, a gaseous compound called butadiene, with a molecular weight of 54, combines nearly 4000 times and gives a polymer known as polybutadiene (a synthetic ...
