This work aims to present the results achieved within the science communication project CV/PVI/1386-Laboratório de Polímeros (Polymer Laboratory), financed by Ciência Viva Agência Nacional para a Cultura Científica e Tecnológica (2006-2008). Several demonstration/experimental kits were developed concerning three main thematics: (1) Polymer concepts; (2) Polymer synthesis and (3) Polymer propert...

ABSTRACT In this article, an approach to teaching molecular biophysics is described. The organization and course content has been carefully chosen curated so that fundamental ideas in can be taught effectively upper classmen higher education. Three general topic areas are introduced along with accompanying experiments illustrate major principles related each area. This article outlines organizi...

Molecular hydrogen plays a key role in structure formation during the early Universe, sometimes cooling the gas and at other times heating it. We discuss three of the key chemical reactions controling the formation of H2 during the epoch of primordial galaxy and first star formation. These are the associative detachment (AD) reaction H−+H→ H2+ e−, the mutual neutral (MN) reaction H−+H+ → H+H, a...
