How to polarise an interface with ions: the discrete Helmholtz model
Hubert Girault, Astrid Johana Olaya Avendano, Grégoire Clément Gschwend
The distribution of electrolytes in an electric field usually relies on theories based on the Poisson-Boltzmann formalism. These models predict that, in the case of a metallic electrode, ionic charges screen the electrode potential, leading to concentratio ...
ROYAL SOC CHEMISTRY2020Mapping of Chemical Heterogeneity at Surfaces with High-Throughput Wide-Field Second Harmonic Microscopy
Many industrial processes are based on electrochemical reactions using engineered electrocatalysts. However, the current lack of theoretical knowledge obscures efforts to maximize catalysts' efficiency, and the optimization process is mostly empirical. To ...
EPFL2020Discrete Helmholtz charge distribution at liquid-liquid interfaces: Electrocapillarity, capacitance and non-linear spectroscopy studies
Hubert Girault, Grégoire Clément Gschwend
The structure of the polarised interface between two immiscible electrolyte solutions (ITIES) has usually been deduced from electrocapillarity and capacitance measurements. However, these two methods only offer an indirect access to the surface change dens ...
ELSEVIER SCIENCE SA2020Negative capacitance semiconductor sensor
Mihai Adrian Ionescu, Ali Saeidi, Francesco Bellando
The present invention relates to a semiconductor sensor (1) comprising: a source element (17, 19); a drain element (21, 23); a semiconductor channel element (25) between the source element (17, 19) and the drain element (21, 23) for forming an electrically ...
2020Assessment of lifestyle changes for greenhouse gas emissions reduction in Switzerland
In light of the climate change crisis, this study looks at what actions can be done by individuals in Switzerland to reduce their carbon footprint. A total of 40 actions spanned over 6 areas of consumption (food, housing, mobility, at home leisure activiti ...
2020Electrosorption at metal surfaces from first principles
Electrosorption of solvated species at metal electrodes is a most fundamental class of processes in interfacial electrochemistry. Here, we use its sensitive dependence on the electric double layer to assess the performance of ab initio thermodynamics appro ...
NATURE PUBLISHING GROUP2020Surface Potential and Interfacial Water Order at the Amorphous TiO2 Nanoparticle/Aqueous Interface
Sylvie Roke, Arianna Marchioro, Marie Bischoff
Colloidal nanoparticles exhibit unique size-dependent properties differing from their bulk counterpart, which can be particularly relevant for catalytic applications. To optimize surface-mediated chemical reactions, the understanding of the microscopic str ...
AMER CHEMICAL SOC2020Highly spatially resolved mapping of the piezoelectric potentials in InGaN quantum well structures by off-axis electron holography
The internal fields in 2.2nm thick InGaN quantum wells in a GaN LED structure have been investigated by using aberration-corrected off-axis electron holography with a spatial resolution of better than 1nm. To improve the spatial resolution, different types ...
2020Structure and reactivity of the polarised liquid–liquid interface: what we know and what we do not
Hubert Girault, Astrid Johana Olaya Avendano, Pekka Eero Peljo, Grégoire Clément Gschwend
Charge transfer phenomena at the interface between two immiscible electrolyte solutions (ITIES) are electrochemical reactions taking place in soft media. Owing to their liquid nature, the ITIES shows a large panel of electrochemical reactions including ele ...
2020A wearable electrochemical sensing system for non-invasive monitoring of lithium drug in bipolar disorder
Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Criscuolo
Lithium represents the main drug for the treatment of Bipolar Disorder (BD) as it acts as a mood stabilizer. However, because of its narrow therapeutic window, psychiatric patients are obliged to frequent tests in hospital to control their lithium blood co ...
