Most of the organic molecules used in chemical industry (and their synthetic precursors) contain oxygen atoms in their structure. One of the most convenient methods for the preparation of oxygenated ...
López Lastra, Adrián (Fecha de defensa: 2020-07-28)
Polymers are one of the most used compounds in the chemical industry because they have application in a wide variety of products for daily use. Polymer preparation and its analysis is a very active field ...
