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 Soc2024Additive Fabrication of Microsupercapacitors
Microsupercapacitors (with footprints from -mm up to -cm scale) have attracted attention for use as electrochemical energy storage devices to power wearables, IoT, and other small microsystems due to their high power density, excellent charge/discharge rev ...
EPFL2023Condition Health Monitoring for Medium-Voltage High-Power Modular Multilevel Converter
Ignacio Alejandro Polanco Lobos
Among the policies to reduce the consequences of GHG emissions, the decarbonization of the electrical, transport, and manufacturing sectors has profoundly changed how the electricity is produced, transmitted, distributed, and consumed, particularly imposin ...
EPFL2022Multiple Effects Induced by Mo6+ Doping in BiVO4 Photoanodes
Kevin Sivula, Charles Roger Jean Lhermitte, Nukorn Plainpan, Annalisa Polo, Ivan Grigioni
Mo6+ doping increases the photoelectrochemical performance of BiVO4 photoanodes in water oxidation. Herein, the underlying mechanisms is elucidated through a systematic structural, morphological, and photoelectrochemical investigation on photoelectrodes of ...
WILEY-V C H VERLAG GMBH2022Development of Lamb wave resonators in thin film X-cut lithium niobate
Microelectromechanical systems (MEMS) is among the most revolutionary technologies of 21st century, with the applications ranging from industrial systems to consumer electronics. Using MEMS in battery-powered wireless devices has long been seen as the evol ...
EPFL2021Reinforced polypyrrole with 2D graphene flakes decorated with interconnected nickel-tungsten metal oxide complex toward superiorly stable supercapacitor
Ulf Anders Hagfeldt, Seyyed Alireza Hashemi
Prompt development of electronic devices and sensors raised the requirement for design/fabrication of advanced energy sources capable of providing considerable amount of energy for consuming platforms through practical nanotechnological approaches. For thi ...
ELSEVIER SCIENCE SA2021Thin film organic electrochemical transistors based on hybrid PANI/PEDOT:PSS active layers for enhanced pH sensing
Danick Briand, Silvia Demuru, Brince Paul Kunnel
We report on organic electrochemical transistors (OECTs) with active channels made of hybrid inkjet-printed poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and electropolymerized polyaniline (PANI) layers, exhibiting simultaneously impro ...
2021Integration of Ultra-Low Volume Pneumatic Microfluidics with a Three-Dimensional Electrode Network for On-Chip Biochemical Sensing
Carlotta Guiducci, Saurabh Tomar, Thomas Ernst
This paper reports a novel miniaturized pseudo reference electrode (RE) design for biasing Ion Sensitive Field Effect Transistors (ISFETs). It eliminates the need for post-CMOS processing and can scale up in numbers with the CMOS scaling. The presented des ...
2021Switchable wetting of oxygen-evolving oxide catalysts
Vasiliki Tileli, Tzu-Hsien Shen
The surface wettability of catalysts is typically controlled via surface treatments that promote catalytic performance. Here we report on potential-regulated hydrophobicity/hydrophilicity at cobalt-based oxide interfaces with an alkaline solution. The swit ...
NATURE PORTFOLIO2021Ion and Trap Induced Dynamic Phenomena in Salt Semiconductor Devices
State-of-the-art organic light-emitting diodes (OLEDs) used in commercial display technology are complex multilayer structures. In contrast, the light-emitting electrochemical cell (LEC) can be built from a single emissive layer sandwiched between two elec ...
