Immobilization of polyoxometalate hybrid catalysts onto mesoporous silica supports using phenylene diisothiocyanate as a cross-linking agent

Ourania Makrygenni, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

The hybrid derivative of heteropolytungstate bearing two aniline groups, namely (nBu4N)3[NaHPW9O34{As(O)C6H4NH2}2], was post-functionalized in the presence of 1,4-phenylene diisothiocyanate (PDITC). The resulting molecular moiety was characterized by IR, 1H and 31P NMR spectroscopy. In a second…

Quantifying Cell Traction Forces at the Individual Fiber Scale in 3D: A Novel Approach Based on Deformable Photopolymerized Fiber Arrays

Pierre Ucla, Joanne Le Chesnais, Henri Ver Hulst, Xingming Ju, Isabel Calvente, Ludovic Leconte, Jean Salamero, Isabelle Bonnet, Catherine Monnot, Hélène Moreau, Jessem Landoulsi, Vincent Semetey, Sylvie Coscoy

The forces exerted by cells upon the fibers of the extracellular matrix play a decisive role in cell motility in development and disease. How the local physical properties of the matrix (such as density, stiffness, orientation) affect cellular forces remains poorly understood. Existing approaches…

Current state of electrochemical techniques and corrosion rate analysis for next-generation materials

Junsoo Han, Oumaïma Gharbi

Current theoretical models and electrochemical techniques used to investigate corrosion mechanisms, including corrosion rates, have been tailored for conventional alloy systems. However, the application of conventional theories and techniques toward next-generation alloys such as multi-principal…

Semiconductor quantum dots reveal dipolar coupling from exciton to ligand vibration

T. Noblet, L. Dreesen, S. Boujday, C. Methivier, Bertrand Busson, A. Tadjeddine, Christophe Humbert

Within semiconductor quantum dots (QDs), exciton recombination processes are noteworthy for depending on the nature of surface coordination and nanocrystal/ligand bonding. The influence of the molecular surroundings on QDs optoelectronic properties is therefore intensively studied. Here, from the…

Antibacterial properties of glycosylated surfaces: variation of the glucosidal moiety and fatty acid conformation of grafted microbial glycolipids

Claire Valotteau, Sophie Roelants, Dasaiyan Prabhu, Susanne Zibek, Michael Günther, Wim Soetaert, Bernd Everaert, Claire-Marie Pradier, Florence Babonneau, Niki Baccile, Vincent Humblot

Glycosylated surfaces can display antimicrobial properties. It has been shown that sophorolipids can be used to develop biocidal coatings against Gram-positive and Gram-negative bacteria, but with a limited efficiency so far. Therefore, it appears necessary to further investigate the surface…

Development of novel cathode materials for the bioelectrocatalysis of oxygen reduction reaction by laccase from Trametes versicolor

Achraf Blout, Alain Pailleret, Claude Jolivalt

Biocatalysts such as enzymes or bacteria constitute an attractive alternative to transition metal catalysts. They have several advantages as they often possess a better selectivity and higher catalytic performances and they can be used in different types of electrochemical devices such as fuel…

In situ detection and characterization of potable water biofilms on materials by microscopic, spectroscopic and electrochemistry methods

Jean Gamby, Alain Pailleret, Carol Boucher Clodic, Claire-Marie Pradier, Bernard Tribollet

We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated in parallel at 20 and 37 °C, in order to focus on the effect of temperature rather than on other operational and water quality parameters. A surface conditioning step was followed as a…
