Gold Nanofilm Redox Catalysis for Oxygen Reduction at Soft Interfaces
Hubert Girault, Pekka Eero Peljo, Micheal Diarmaid Scanlon, Evgeny Smirnov
Functionalization of a soft or liquid-liquid interface by a one gold nanoparticle thick “nanofilm” provides a conductive pathway to facilitate interfacial electron transfer from a lipophilic electron donor to a hydrophilic electron acceptor in a process kn ...
Elsevier2016Mesoscopic framework for organic-inorganic perovskite based photoelectric conversion device and method for manufacturing the same
Michael Graetzel, Shaik Mohammed Zakeeruddin, Mingkui Wang
The invention discloses a perovskite solar cell and a method of fabrication thereof. The perovskite solar cell sequentially comprises a transparent electrode, a mesoporous P-I-N framework and a counter electrode from the bottom to top; the mesoporous P-I-N ...
2016Synergistic Coupling Between Electrochemical and Ultrasound Treatments for Organic Pollutant Degradation as a Function of the Electrode Material (IrO2 and BDD) and the Ultrasonic frequency (20 and 800 kHz)
César Pulgarin, Erika Herrera Calderon, Fernando Guzman Duque
Solutions of the organic pollutant model, Crystal Violet (CV), were subjected to ultrasonic, electrochemical treatment and its combination. Ultrasound was tested at two frequencies (20 kHz or 800 kHz) and 80 W in deionized water. After 120 min, 20 kHz cond ...
Esg2016Rate Law Analysis of Water Oxidation and Hole Scavenging on a BiVO4 Photoanode
Spectroelectrochemical studies employing pulsed LED irradiation are used to investigate the kinetics of water oxidation on undoped dense bismuth vanadate (BiVO4) photoanodes under conditions of photoelectrochemical water oxidation and compare to those obta ...
Amer Chemical Soc2016Analytical sensing platforms with inkjet printed electrodes
Hubert Girault, Frédéric Gumy, Andreas Stephan Lesch, Milica Jovic, Sunny Isaïe Maye
Disposable amperometric electrode chips enable the rapid, cost-effective and reliable monitoring of the concentration of analytes in fluidic samples. One example of high relevance in the health sector is the detection of hydrophilic antioxidants in fruit j ...
2016Role of microstructure on electrode operating mechanisms for mixed ionic electronic conductors: From synchrotron-based 3D reconstruction to electrochemical modeling
A typical La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) electrode was reconstructed by X-ray nanotomography. The new Nano Imaging beamline ID16A-NI of the European Synchrotron Radiation Facility (ESRF) was used to conduct the investigation. Particular attention was ...
Elsevier Science Bv2016Wireless Monitoring of Endogenous and Exogenous Biomolecules on an Android Interface
Giovanni De Micheli, Sandro Carrara, Francesca Stradolini, Irene Taurino, Cristina Boero, Camilla Baj-Rossi, Grégoire Casimir Joseph Surrel, Stefano Riario
Monitoring patients in intensive care units is generally expensive and time consuming. A prompter medical intervention for those critical patients is a key factor for their safety. Therefore, a system that offers immediate visualization of the monitored da ...
