Wireless coupling of conducting polymer actuators with light emission


Thursday, 21 February 2019
B. Gupta, M. C. Afonso, L. Zhang, C. Ayela, P. Garrigue, B. Goudeau, A. Kuhn ChemPhysChem (2019) in press Combining the actuation of conducting polymers with additional functionalities is an interesting fundamental scientific challenge and increases their application potential. Here we demonstrate the possibility of direct integration of a miniaturized light emitting diode (LED) in a polypyrrole (PPy) matrix in order to achieve simultaneous wireless actuation and light emission. A light... Read More...

Facile Fabrication of Surface-Imprinted Macroporous Films for Chemosensing of Human Chorionic Gonadotropin Hormone

M. Dąbrowski, A. Ziminska, J. Kalecki, M. Cieplak, W. Lisowski, R. Maksym, S. Shao, F. D’Souza, A. Kuhn, P. S. Sharma ACS Applied Materials and Interfaces (2019) in press We present an improved approach for the preparation of highly selective and homogeneous molecular cavities in molecularly imprinted polymers (MIP) via the combination of surface imprinting and semi-covalent imprinting. Towards that, first a colloidal crystal mold was prepared via the Langmuir-Blodgett technique. Then, human... Read More...

Wireless Addressing of Freestanding MoSe2 Macro- and Microparticles by Bipolar Electrochemistry


Wednesday, 23 January 2019
I. Malytska, Th. Doneux, M. Bougouma, A. Kuhn, L. Bouffier. J. Phys. Chem. C, 2019, in press Doping of a transition-metal dichalcogenide deposited onto a conducting surface acting as bipolar electrode was recently reported. Here, freestanding macro- and microscale transition-metal dichalcogenide substrates are successfully employed as effective bipolar electrodes without the need of using an additional conducting support. This is first demonstrated by achieving site-selective bipolar... Read More...

Communiqué de presse du CNRS - Un « boost » pour les biopiles


Friday, 19 October 2018
Une biopile capable de fournir suffisamment d’énergie pour alimenter un pacemaker... Cet outil idéal pourrait bien devenir une réalité grâce au résultat de notre collaboration avec le Centre de Recherche Paul Pascal (CNRS / Université de Bordeaux) et l'équipe de Peer Fischer à l'Université de Stuttgart et l'Institut Max Planck. Nous avons effectivement démontré qu'il était possible d'accroître la puissance fournie par une biopile en y insérant un système microélectronique ce... Read More...

Zeste de Science du CNRS
