Electropolymerization of Polypyrrole by Bipolar Electrochemistry in an Ionic Liquid
In our last paper published in Langmuir, pyrrole has been electropolymerized on a bipolar electrode - either in ionic liquid or in acetonitrile - and the resulting polymer films were characterized by Scanning Electron Microscopy and by contact profilometry.
A new tool for Transfer of Technology
Launched in last January, the BrivaTech cluster is your privileged interlocutor if you are interested in using some of the technologies developed in the NSysA research group.
Site-Selective Synthesis of Janus-type Metal-Organic Framework Composites
Bipolar electrochemistry is applied in a straightforward way to the site-selective in situ synthesis of metal–organic framework structures. The novelty of the presented work is that the deposit can be intentionally confined to a defined area of a substrate without using masks or templates.
Electrochemistry of Biosystems
Part of our research activities are devoted to the development of sensors and methodologies for the detection of biological activities in order to elucidate with biologists and clinicians fundamental metabolic or genetic mechanisms.
Mapping the Electrogenerated Chemiluminescence Reactivity in Space: Mechanistic Insight into Model Systems Used in Immunoassays
The remarkable characteristics of electrogenerated chemiluminescence (ECL) as a readout method are successfully exploited in microbead-based immunoassays.
Straight-forward Synthesis of Ringed Particles
Here, we report the straightforward chemical synthesis of complex metallic ring structures on the surface of spherical particles using an original template-free bulk process.
Impact of pNIPAM Microgel Size on their Ability to stabilize Pickering Emulsions
In this Langmuir publication, we studied the influence of the particle size on the ability of poly(N-isoprolylacrylamide) microgels to stabilize direct oil-in-water Pickering emulsions. The microgel size wass varied from 250 to 760 nm, the cross-linking density being kept constant.

First Co(III) complexes with (1,3-selenazol-2-yl)hydrazones as an unexplored class of ligands were prepared and characterized by NMR spectroscopy and X-ray diffraction analysis. Novel ligands act as NNN tridentate chelators forming octahedral Co(III) complexes. The impact of structural changes on ligands' periphery as well as isosteric replacement of sulphur with selenium on electrochemical, and electronic absorption features of complexes are explored. To support the experimental data, density functional theory (DFT) calculations were also conducted. Theoretical NMR chemical shifts, the relative energies and natural bond orbital (NBO) analysis are calculated within the DFT approach, while the singlet excited state energies and HOMO-LUMO energy gap were calculated with time-dependent density functional theory (TD-DFT). The electrophilic f– and nucleophilic f+ Fukui functions are well adapted to ﬁnd the electrophile and nucleophile centres in the molecules. Both, (1,3-selenazol-2-yl)- and (1,3-thiazol-2-yl)hydrazone Co(III) complexes showed potent antimicrobial and antioxidant activity. Significant difference among them was a smaller cytotoxicity of selenium compounds.
