Brazoide E, a New Alkaloid and Other Compounds from Justicia wasshauseniana (Acanthaceae)

Renata D. Fernandes, Raimundo Braz‐Filho, Mário Geraldo de Carvalho, Denise Monte Braz et autres

A new alkaloid, named brazoide E (6), three known steroids (campesterol, β-sitosterol, stigmasterol), two glucosides (3-O-β-D-glucopyranosylsitosterol and 3-O-β-D-glucopyranosyl stigmasterol) and sucrose were isolated from the leaves and stems of Justicia wasshauseniana. Their structures were characterized using high-resolution electrospray ionization mass spectrometry (HRESIMS), …

The Corrosion Inhibition Performance of Eco-Friendly bis-Schiff Bases on Carbon Steel in a Hydrochloric Solution

Arthur Valbon, Neubi Francisco Xavier, Mariana Falcão Lopes Princisval Carlos, Glauco Favilla Bauerfeldt et autres

Corrosion inhibitors are widely used as an important tool for the prevention and remediation of different materials exposed to corrosive industrial processes. Corrosion inhibitors are usually added to acid pickling solutions to reduce the deterioration of metallic materials and particularly, corrosion due …

Theoretical and experimental study of the OH radical with 3‐bromopropene gas phase reaction rate coefficients temperature dependence

Mauro González Vera, Pablo Marcelo Cometto, Juan Manuel Casañas, Glauco Favilla Bauerfeldt et autres

Abstract In this work, the rate‐determining steps of the OH radical + 3‐bromopropene gas phase reaction were studied, which could explain for the possible negative activation energy observed in experiments. To obtain new kinetic parameters and data for critical revisions, a reinvestigation …

Theoretical insights into the methane catalytic decomposition on graphene nanoribbons edges

Neubi Francisco Xavier, Anthony J. R. Payne, Glauco Favilla Bauerfeldt, Marco Sacchi

Catalytic methane decomposition (CMD) is receiving much attention as a promising application for hydrogen production. Due to the high energy required for breaking the C-H bonds of methane, the choice of catalyst is crucial to the viability of this process. However, atomistic …
