Urea electro-oxidation byproducts impact on NiO/NiOOH anode performance studied by operando electrochemical impedance spectroscopy

Sophia Akkari, Vincent Vivier, Carlos Sánchez-Sánchez

With significant quantities of urea (CO(NH2)2) being worldwide produced and its presence at high concentration in urine, simultaneous treatment of urea effluents and hydrogen production by paired electrolysis represents a very attractive approach in circular economy. Urea electro-oxidation on Ni-…

Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

Karam Jabbour, Pascale Massiani, Anne Davidson, Sandra Casale, Nissrine El Hassan

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…

Electronic structure investigation of biphenylene films

R. Totani, C. Grazioli, Tiantian Zhang, I. Bidermane, J. Lüder, M. de Simone, M. Coreno, B. Brena, L. Lozzi, C. Puglia

Photoelectron Spectroscopy (PS) and Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy have been used to investigate the occupied and empty density of states of biphenylene films of different thicknesses, deposited onto a Cu(111) crystal. The obtained results have been compared to…

Modification des propriétés de surface d'un polypropylène en vue de l'immobilisation de biomolécules aux propriétés antibactériennes, Modification of surface properties of polypropylene for immobilization of antibacterial biomolecules

Simon Léoment

Depuis la nuit des temps, l’homme a fabriqué et utilisé des produits cosmétiques. De la Gaule à l’Egypte, en passant par l’Empire Romain et la Grèce antique, les hommes et les femmes s’appliquaient sur le visage et le corps des produits naturels ou transformés (huiles, poudres, mixtures, laits, etc…, Since the dawn of time, man has manufactured and used cosmetic products. From Gaul to Egypt, passing through the Roman Empire and ancient Greece, men and women applied to the face and body of natural or processed products (oils, powders, mixtures, milks, etc.) in order to embellish oneself, to heal…

Phosphorylation of a conserved serine in the deoxyribonucleic acid binding domain of nuclear receptors alters intracellular localization.

Kai Sun, Vedrana Montana, Karthikeyani Chellappa, Yann Brelivet, Dino Moras, Yutaka Maeda, Vladimir Parpura, Bryce M Paschal, Frances M Sladek

Nuclear receptors (NRs) are a superfamily of transcription factors whose genomic functions are known to be activated by lipophilic ligands, but little is known about how to deactivate them or how to turn on their nongenomic functions. One obvious mechanism is to alter the nuclear localization of…

Evolution Mechanisms of T91 Steel in Subcritical Conditions and Role of an Internal Oxidation Zone

Seifallah Fetni, David Montero, Chokri Boubahri, Dalil Brouri, Jalel Briki

Corrosion of a T91 steel tube, used in subcritical conditions in an oil power plant for 157,000 h, was characterized mainly through SEM, TEM, EDX and DRX analyses. Severe oxidation and carburization took place in both the outer (boiler) and inner (steam) wall sides. The nature and morphology of the…

Polarizable QM/Classical Approaches for the Modeling of Solvation Effects on UV–Vis and Fluorescence Spectra: An Integrated Strategy

Daniele Loco, Natalia Gelfand, Sandro Jurinovich, Stefano Protti, Alberto Mezzetti, Benedetta Mennucci

Hybrid methods combining quantum chemistry and classical models are largely used to describe solvent effects in absorption and emission processes of solvated chromophores. Here we compare three different formulations of these hybrid approaches, using a continuum, an atomistic, or a mixed…

Physico-chemical properties of FeAlBEA and FeSiBEA zeolites and their catalytic activity in the SCR of NO with ethanol or methane

Janusz Janas, Stanislaw Dzwigaj

FeAlBEA and FeSiBEA zeolites are prepared by a conventional ion exchange and a two-step postsynthesis method, respectively. Their physico-chemical properties are investigated by XRD, FTIR, and diffuse reflectance UV-vis. For FeAlBEA zeolite, framework tetrahedral Fe(III), extra-framework octahedral…

Adsorption properties of Fe-containing dealuminated BEA zeolites as revealed by FTIR spectroscopy

Konstantin Hadjiivanov, Elena Ivanova, Radoslav Kefirov, Janusz Janas, Anna Plesniar, Stanislaw Dzwigaj, Michel Che

Adsorption properties of Fe-containing dealuminated BEA zeolites were investigated by FTIR spectroscopy of adsorbed CO and NO. Two Fe-containing SiBEA zeolite samples were prepared by a two-step post-synthesis method: creation of vacant T-atom sites (T = Si, Al) by dealumination of…
