Fully printed 3 microns thick dielectric elastomer actuator

Herbert Shea, Samuel Rosset, Alexandre Poulin

In this work we present a new fabrication technique to print thin dielectric elastomer actuators (DEAs), reducing the driving voltage below 300 V while keeping good actuation performance. With operation voltages in the kV-range, standard DEAs are limited i ...

Reconstitution of [Fe]-hydrogenase using model complexes

Xile Hu, Matthew Wodrich, Tao Xu, Dafa Chen

[Fe]-Hydrogenase catalyses the reversible hydrogenation of a methenyltetrahydromethanopterin substrate, which is an intermediate step during the methanogenesis from CO2 and H-2. The active site contains an iron-guanylylpyridinol cofactor, in which Fe2+ is ...

Enhancing the Performance of a Robust Sol-Gel-Processed p-Type Delafossite CuFeO2 Photocathode for Solar Water Reduction

Kevin Sivula, Nestor Guijarro Carratala, Mathieu Steven Prévot

Delafossite CuFeO2 is a promising material for solar hydrogen production, but is limited by poor photocurrent. Strategies are demonstrated herein to improve the performance of CuFeO2 electrodes prepared directly on transparent conductive substrates by usin ...

Solar Hydrogen Production by Amorphous Silicon Photocathodes Coated with a Magnetron Sputter Deposited Mo

Christophe Ballif, Xile Hu, Björn Niesen, Laurent Liardet, Carlos Gilberto Morales Guio

Coupling of Earth-abundant hydrogen evolution catalysts to photoabsorbers is crucial for the production of hydrogen fuel using sunlight. In this work, we demonstrate the use of magnetron sputtering to deposit Mo2C as an efficient hydrogen evolution reactio ...

Hydrogen and Hydrogen Peroxide Formation in Trifluorotoluene-Water Biphasic Systems

Hubert Girault, Jonnathan Cesar Hidalgo Acosta

Hydrogen or hydrogen peroxide can be generated in liquid-liquid biphasic systems, where the organic phase contains sufficiently strong electron donor (whose redox potential is lower than the potential of reversible hydrogen electrode). H2O2 generation with ...

Study of the Redox Properties of Singlet and Triplet Tris(2,2 '-bipyridine)ruthenium(II) ([Ru(bpy)(3)](2+)) in Aqueous Solution by Full Quantum and Mixed Quantum/Classical Molecular Dynamics Simulations

Ursula Röthlisberger, Ivano Tavernelli, Polydefkis Diamantis, Jérôme Florian Gonthier

The oxidation of ground-state (singlet) and triplet Ru(bpy)(3) were studied by full quantum-mechanical (QM) and mixed quantum/classical (QM/MM) molecular dynamics simulations. Both approaches provide reliable results for the redox potentials of the t ...

Understanding the Role of Underlayers and Overlayers in Thin Film Hematite Photoanodes

Michael Graetzel, Stanley David Tilley, Ludmilla Steier

Recent research on photoanodes for photoelectrochemical water splitting has introduced the concept of under-and overlayers for the activation of ultrathin hematite films. Their effects on the photocatalytic behavior were clearly shown; however, the mechani ...

Ruthenium Oxide Hydrogen Evolution Catalysis on Composite Cuprous Oxide Water-Splitting Photocathodes

Michael Graetzel, Morgan Mertens Stefik, Stanley David Tilley, Marcel Roland Schreier

Photocathodes based on cuprous oxide (Cu2O) are promising materials for large scale and widespread solar fuel generation due to the abundance of copper, suitable bandgap, and favorable band alignments for reducing water and carbon dioxide. A protective ove ...

Hydrogen evolution from a copper(I) oxide photocathode coated with an amorphous molybdenum sulphide catalyst

Michael Graetzel, Xile Hu, Heron Vrubel, Stanley David Tilley, Carlos Gilberto Morales Guio

Concerns over climate change resulting from accumulation of anthropogenic carbon dioxide in the atmosphere and the uncertainty in the amount of recoverable fossil fuel reserves are driving forces for the development of renewable, carbon-neutral energy tech ...
