Abstract

In difficult times, it is with great pleasure that we offer the community the third issue of the Quarks – Brazilian Electronic Journal of Physics, Chemistry and Materials Science.

Given the broad scope of the Quarks periodic, a range of experts in their fields of study provides their research from fundamental science to materials with biological and optical applications.

In addition to studies developed by Brazilian groups, researchers from countries such as Spain, France, Germany, Russia, and Switzerland have contributed to this present issue.
