(Universidad Santo TomásPregrado Ingeniería MecánicaFacultad de Ingeniería Mecánica, 2020-10-22)
Since the industrial revolution began, the world's population has experienced the effects of air pollution caused by fossil fuels. Year by year, the quality of the air we breathe have decreased due to the burning of fossil ...
Nontwist symplectic maps in tokamaks
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We review symplectic nontwist maps that we have introduced to describe Lagrangian transport properties in magnetically confined plasmas in tokamaks. These nontwist maps are suitable to describe the formation and destruction ...
DBSA to improve the compatibility, solubility, and infusibility of cellulose nanowhiskers modified by polyaniline in reinforcing a natural rubber-based nanocomposite
(2019-07-01)
In this study, the authors evaluate the potential of the reinforcement of cellulose nanowhiskers coated with polyaniline-DBSA (CNW-PANiDB) in a natural rubber latex nanocomposite. For this purpose, cellulose nanowhiskers ...
