Immobilization of metals on carbon nanotubes through non-covalent approaches – focus on the use of polymerized lipidic interfaces to prepare catalytic hybrids

Polymerized lipidic hemi-micellar rings formed around carbon nanotubes create robust and modular interfaces for metal species immobilization. These architectures preserve nanotube integrity and provide recyclable, high-performance catalytic systems.

Mechanistic investigation of the denitrosylation activity of a water-soluble copper(II) compound probed by experimental and computational approaches

A water-soluble Cu(II) compound promotes the denitrosylation of GSNO at room temperature and physiological pH. A reaction mechanism was proposed based on kinetic, spectroscopic, and spectrometric experiments, further supported by DFT calculations.

A new water-soluble Ni(II) complex as a prototype of metallodrugs to treat toxoplasmosis

The Ni(II) compound showed higher activity (IC50 = 380 nM) on T. gondii than sulfadiazine and was nontoxic to the host cell (selective index > 1800). TEM studies showed that the compound induces deformation in the parasite's conoid structure.

About this collection

This special collection of Inorganic Chemistry Frontiers entitled “XXI BMIC/X BMRE/ III WTBC” is dedicated to commemorating the 2024 Brazilian Meeting on Inorganic Chemistry (BMIC), which was held in Belo Horizonte, Brazil from 12th-15th September 2024.

The collection aims to facilitate discussions on the latest developments in thematic areas such as biological inorganic chemistry, organometallics, rare-earths, supramolecular chemistry, photochemistry, inorganic electrochemistry, materials chemistry, and catalysis.

Guest Editors: Luiz Antônio S. Costa (Federal University of Juiz de Fora),  Fernando Sigoli (State University of Campinas), Heveline Silva (Federal University of Minas Gerais) and Maria Helena Araujo (Federal University of Minas Gerais)

More articles will be added into the collection as soon as published.
