Becoming Full Open Access

The beginning of a New Year is the time when we all stop to evaluate what happened during the closing year, and think about what lies ahead for the new one.This assessment is traditionally the topic of the Journal of the Brazilian Chemical Society (JBCS) first Editorial every year.
For us, the year of 2016 marked the transition to full Open Access system, with the requirement that all authors of the JBCS should contribute with page charges in order to meet the financial demand to maintain the Publishing Office and Journals of the Brazilian Chemical Society (this was accompanied by the other three major Journals published by PubliSBQ). This transition also happens at a time in which all the major scientific publishers, whether linked to Scientific Societies like us, or to private publishers, are going in the same direction.

Supramolecular Approach to Decorate Multi-Walled Carbon Nanotubes with Negatively Charged Iron(II) Complexes

Sergio A. V. Jannuzzi; Bianca Martins; Luis E. S. C. Huamaní; André L. B. Formiga

How to cite this article

A method to reversibly decorate multi-walled carbon nanotubes with metallopolymers is presented. The strategy is applied to polymers with pending iron complexes in different iron(II):monomer ratios resulting in very stable suspensions of the CNT, in ethanol. They can be used to prepare conducting surfaces with a supramolecular arrangement preserving the intrinsic properties of both metallopolymer and CNT. Details are presented in the Article Supramolecular Approach to Decorate Multi-Walled Carbon Nanotubes with Negatively Charged Iron(II) Complexes by Sergio A. V. Jannuzzi, Bianca Martins, Luis E. S. C. Huamaní and André L. B. Formiga on page 2.

Five new sesquiterpenoids were isolated from the essential oil of the leaves of Nectandra megapotamica (Lauraceae). Their structures were elucidated by spectroscopic analysis, and the relative configurations were proposed by their nuclear Overhauser effect (NOESY) spectrum. Three compounds displayed significant antimicrobial activity.
