Theoretical and experimental study of the bending influence on the capacitance of interdigitated micro-electrodes patterned on flexible substrates

Nico de Rooij, Danick Briand, Francisco Molina Lopez

Interdigitated electrodes are common structures in the fields of microelectronics and MEMS. Recent developments in flexible electronics compel an understanding of such structures under bending constraints. In this work, the behavior of interdigitated micro ...

First-Principles Prediction of the Equilibrium Shape of Nanoparticles Under Realistic Electrochemical Conditions

Nicola Marzari, Nicéphore Arthur François Bonnet

A first-principles model of the electrochemical double layer is applied to study surface energies and surface coverage under realistic electrochemical conditions and to determine the equilibrium shape of metal nanoparticles as a function of applied potenti ...

The role of Hartree-Fock exchange in the simulation of X-ray absorption spectra: A study of photoexcited [Fe(bpy)(3)](2+)

Majed Chergui, Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Gloria Capano, Marco Eli Reinhard, Mercedes Hannelore Rittmann-Frank

We present a theoretical analysis for the K- and L-2/3-edge static and picosecond X-ray absorption spectra of Fe(bpy)(3). Simulations of the pre-edge region at the Fe K-edge using time-dependent density functional theory demonstrate the importance of ...

Dynamics of interfacial electron transfer and primary charge separation in dye-sensitized solar cells based on heteroleptic Ru(II) polypyridyl complexes

Jacques-Edouard Moser, Arianna Marchioro, Jan Cornelius Brauer

In dye-sensitized solar cells (DSCs), ultrafast electron injection from a photoexcited molecular sensitizer into the conduction band of a wide- bandgap semiconductor is key to efficient charge separation. According to the current understanding of DSCs func ...

Enhancing Hydrophilicity of Anatase TiO2 Surfaces by Deposition of Alkaline Earths: The Case of Ca

Michel Posternak, Alfonso Baldereschi

We show with DFT calculations within the COSMO framework that the wetting energy of clean or hydroxylated anatase TiO2 surfaces is strongly enhanced by Ca deposition at low coverage. Two mechanisms contribute to this behavior: the ionic character of Ca ads ...

Repulsion forces of superplasticizers on ground granulated blast furnace slag in alkaline media, from AFM measurements to rheological properties

Paul Bowen, Michael Stuer, Ulrich Aschauer

The electrostatic and steric repulsion induced by different superplasticizers on ground granulated blast furnace slag in alkaline media have been studied. The superplasticizers were sulfonated naphthalene, sulfonated melamine, vinyl copolymer, and polycarb ...

The Transient Photocurrent and Photovoltage Behavior of a Hematite Photoanode under Working Conditions and the Influence of Surface Treatments

Michael Graetzel, Kevin Sivula, Florian Le Formal

Hematite (alpha-Fe2O3) is widely recognized as a promising candidate for the production of solar fuels via water splitting, but its intrinsic optoelectronic properties have limited its performance to date. In particular, the large electrochemical overpoten ...

Influence of the counter electrode on the photovoltaic performance of dye-sensitized solar cells using a disulfide/thiolate redox electrolyte

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Julian Burschka

Strong scientific interests focus on the investigation of iodine-free redox couples for their application in dye-sensitized solar cells (DSCs). Recently, a disulfide/thiolate-based redox electrolyte has been proposed as a valuable alternative to the conven ...
