Contrasting Views of the Electric Double Layer in Electrochemical CO2 Reduction: Continuum Models vs Molecular Dynamics
In the field of electrochemical CO2 reduction, both continuum models and molecular dynamics (MD) models have been used to understand the electric double layer (EDL). MD often focuses on the region within a few nm of the electrode, while continuum models ca ...
Amer Chemical Soc2024Processing factors affecting roughness, optical and mechanical properties of nanocellulose films for optoelectronics
This work aims to understand how nanocellulose (NC) processing can modify the key characteristics of NC films to align with the main requirements for high-performance optoelectronics. The performance of these devices relies heavily on the light transmittan ...
Elsevier Sci Ltd2024Second harmonic scattering of nanoparticles: A journey into the electrical double layer
In aqueous solutions, a charged surface causes the redistribution of nearby ions. The ion layers formed are known as the electrical double layer (EDL), and are widespread in many systems involving electrochemistry, colloidal science, biomedicine, and energ ...
EPFL2024Polymeric integration of structure-switching aptamers on transistors for histamine sensing
Nako Nakatsuka, Mattia Petrelli
Aptamers that undergo large conformational rearrangements at the surface of electrolyte-gated field-effect transistor (EG-FETs)-based biosensors can overcome the Debye length limitation in physiological high ionic strength environments. For the sensitive d ...
2023Revealing the Formation Dynamics of Janus Polymer Particles: Insights from Experiments and Molecular Dynamics
Seeded emulsion polymerization is one of the best-known methods for preparing polymer particles with a controlled size, composition, and shape. It first requires the preparation of seed particles, which are then swollen with additional monomer (the same as ...
Washington2023Colloidal transport and deposition through dense vegetation
David Andrew Barry, Li Chen, Congrong Yu
The effectiveness of submerged synthetic aquatic vegetation on removal of colloids from flowing water was investigated to explore retention of particulate nonpoint source pollutants in aquatic systems. In colloid transport experiments, the deposition rate ...
2022Molecular insights into the electrical double layer of colloidal oxide particles obtained through second harmonic scattering
Photocatalytic applications play an essential role in the search for alternative energy sources and environmental decontamination techniques. It is of fundamental interest to understand on a molecular level the aqueous solid/liquid interface, where photoca ...
EPFL2022Electrokinetic, electrochemical, and electrostatic surface potentials of the pristine water liquid-vapor interface
Although conceptually simple, the air-water interface displays rich behavior and is subject to intense experimental and theoretical investigations. Different definitions of the electrostatic surface potential as well as different calculation methods, each ...
AIP Publishing2022Precipitation, Characterization, Kinetic, and Thermodynamic Modelling of Synthetic C-S-H Systems (C-S-H, CASH, CSH+$)
This thesis investigates the effects of aluminates, sulfates, and heterogeneous substrates on the nucleation and growth of synthetic calcium-silicate-hydrates (C-S-H) produced by dropwise precipitation. The use of synthetic C-S-H, separate from other cemen ...
EPFL2022Water Orientation at the Anatase TiO2 Nanoparticle Interface: A Probe of Surface pKa Values
Arianna Marchioro, Marie Bischoff
The acid-base properties of surfaces significantly influence catalytic and (photo)electrochemical processes. Estimation of acid dissociation constants (pKa values) for colloids is commonly performed through electroanalytical techniques or spectroscopic met ...
