      Platonium remporte le trophée Récylum des lumières durables 2016

      Trophee Recyclum

      Cette œuvre artistique « son et lumières » est un foisonnement d’idées inédites, comme son colossal vortex de lumière, sa zapping zone vidéo ou encore l’utilisation de la luminescence naturelle de matériaux.
      Elle se nourrit intégralement de recherches et d’innovations lyonnaises à décrypter sur ce site .
      Matériaux et prestataires sont tous de l’agglomération lyonnaise. Et surtout, le spot central de l’installation prend vie grâce à un ensemble de bandes lumineuses alimentées par des leds : ce vortex de lumières est aussi imposant que faible en consommation électrique. Ces bandes sont actuellement étudiées à IRCELYON pour dépolluer l’air et l’eau : une innovation particulièrement intéressante.

      Platonium : le CNRS à la Fête des lumières à Lyon du 5 au 8 décembre 2016

      L'IRCELYON présente un de ses thème de recherches à l'Hôtel de Ville

      tissus Brochier

      Pour plus d'info, rendez-vous sur www.cnrs.fr/platonium

      Entièrement pensée à partir de recherches actuelles ré-interprétées par le regard des artistes, E. Michel et AL. Ishii, les visiteurs sont conduits dans un voyage vers la lumière. Après l'Atrium et sa 'Zapping zone',  un puits de lumière monumental plonge dans le sol de la cour principale de l'Hôtel de Ville. Cette hyper-structure est un montage inédit de fines bandes de tissus lumineux, réalisées par Brochier Technologies, actuellement étudiées comme outil possible de dépollution de l’air et de l’eau par l’IRCELYON.  Entretien Chantal Guillard

      A recent paper in Angewandte Chemie

      Organosulfate Formation through the Heterogeneous Reaction of Sulfur Dioxide with Unsaturated Fatty Acids and Long-Chain Alkenes

      Collaboration between Chinese, Canadian and French laboratories recently demonstrated that sulfur dioxide reacts with a range of fatty acids and long-chain alkenes to lead to the formation of organosulfur products. This reaction, which even takes place in the presence of ozone, is enhanced by light irradiation. The reaction products have the same composition as some organosulfur compounds that have been detected in atmospheric aerosols.

      IRCELYON partner of the H2020 NMBP program “PRODIA”

      PROduction, control and Demonstration of structured hybrid nanoporous materials for Industrial adsorption Applications

      ProDIA  aims to accelerate the industrialisation  of hybrid nanoporous materials in Europe. This collaborative programm will focus on the development of reliable  production methods of nanoporous powders including activation and shaping processes. Main objectives are :

      • To develop production technologies and methods, including shaping, for MOFs and aluminosilicates, which are price competitive (10-100 €/kg).
      • To set-up production facilities in Europe for the production of a variety of NPMs with chemical and mechanical stabilities and with safety requirements which allow them to be sold, distributed and used in the industry.
      • To demonstrate the industrial relevance of NPMs in gas storage, air purification, heat pumps and health care applications.

      2 PhD of Ircelyon win the prize of FCCat for their posters

      Davide LORITO et Jihene SOUFI

       

      The French Conference on Catalysis (FCCat) was an opportunity for the French and the International Catalysis community to share most advanced results in a friendly spirit. Contributions dealing with homogeneous and heterogeneous catalysis, ranging from reaction mechanism to catalytic process design, were discussed between academia and industry participants.

      µ-Nitrido diiron phthalocyanine and porphyrin complexes: remarkable catalysts for several challenging reactions

      Review of P. Afanasiev and A. B. Sorokin published in Accounts of Chemical Research

      sorokin complexes

      New approach in catalysis is proposed in IRCELYON. µ-Nitrido diiron phthalocyanine and porphyrin complexes, previously considered as inactive in catalysis, are remarkable catalysts for several challenging reactions. These bio-inspired complexes feature particular structural, electronic and especially catalytic properties. They can be used for the oxidation of methane, ethane and benzene, as well as for the C-C bond forming and oxidative dehalogenation of C-Cl and C-F bonds. Mechanistic background of this approach and unusual catalytic properties of µ-nitrido diiron species are described in the recent review. Due to accessibility and structural flexibility of their structure in terms of ligands, metals and bridging group, these complexes have a great potential for further development at fundamental and industrial level.
