Cost-effective equalization of electro-optic frequency combs in a Sagnac interferometer
Camille Sophie Brès, Jianqi Hu, Ivan Cardea
We present a cost-effective electro-optic frequency comb generation and equalization method using a single phase modulator inserted in a Sagnac interferometer layout. The equalization relies on the interference of comb lines generated in both clockwise and ...
Optica Publishing Group2023In Situ Infrared Spectroscopy of NOx Reduction Catalysts: A Laboratory Exercise for In-Person and Virtual Learning
Davide Ferri, Oliver Kröcher, Rob Jeremiah G. Nuguid
Infrared (IR) spectroscopy and catalysis represent two of the most practically relevant topics in chemistry, but they are normally taught in separate contexts at the undergraduate level. Although IR spectroscopy is introduced to students as a tool for orga ...
AMER CHEMICAL SOC2022In situ nanoscale studies of copper-based catalysts for carbon dioxide electroreduction
The urgency of climate change demands the simultaneous removal of carbon dioxide from the atmosphere and the transition to renewable energy sources. This aim is realizable through electrochemical reduction of carbon dioxide (CO2RR), which is a promising ro ...
EPFL2021Photo- and thermally-induced electronic and structural dynamics in perovskites and transition metal oxides
In this thesis, we exploited optical and X-ray pump-probe methods in a synergistic approach to study the interplay of the electronic, spin and structural degrees of freedom in two class of complex systems relevant for solar energy conversion applications: ...
EPFL2021A Low Power 35 GHz HEMT Oscillator for Electron Spin Resonance Spectroscopy
Giovanni Boero, Nergiz Sahin Solmaz, Alessandro Valentino Matheoud
This paper presents a low power microwave oscillator designed as sensor for electron spin resonance (ESR) spectroscopy. Low power consumption is necessary for low temperature operation. Additionally, lower power consumption allows for a lower microwave mag ...
IEEE2021Reduction of PdO/Al2O3 in Liquid Cyclohexane Followed In Situ by ATR-IR, High-Energy XRD, and XAS
Supported Pd-based catalysts used in heterogeneously catalyzed liquid phase processes often undergo an activation step through reduction of the oxide phase or of the oxidic passivation layer prior to reaction. An oxidized Pd/Al2O3 catalyst was reduced by u ...
AMER CHEMICAL SOC2021Liquid phase in situ spectroscopic investigations of heterogeneous catalysts
Thibault Xavier Florian Fovanna
In this work, we have studied various aspects of catalysts and catalytic processes at the solid-liquid interface, e.g. the reduction of supported PdO, the formation of Pd hydrides, their quantification, the their reactivity in a transient in time-resolved ...
EPFL2020Metal-organic framework derived copper catalysts for CO2 to ethylene conversion
The electrochemical reduction of CO2 to ethylene provides a carbon-neutral avenue for the conversion of CO2 to value-added fuels and feedstocks, so contributing to the storage of intermittent renewable electricity. The exploration of efficient electrocatal ...
ROYAL SOC CHEMISTRY2020New Evidence for Ag-Sputtered Materials Inactivating Bacteria by Surface Contact without the Release of Ag Ions: End of a Long Controversy?
The study provides new evidence for Ag-coated polyester (PES) mediating Escherichia colt inactivation by way of genetically engineered E. coli (without porins, from now denoted porinless bacteria). This allows the quantification of the bactericidal kinetic ...
AMER CHEMICAL SOC2020From synchrotrons for XFELs: the soft x-ray near-edge spectrum of the ESCA molecule
A predictive understanding of soft x-ray near-edge absorption spectra of small molecules is an enduring theoretical challenge and of current interest for x-ray probes of molecular dynamics. We report the experimental absorption spectrum for the electron sp ...
