Hiding in Plain Sight: The Issue of Hidden Variables
Here we discuss "hidden variables", which are typically introduced during an experiment as a consequence of the application of two independent variables together to create a stimulus. With increased sophistication in modern chemical biology tools and relat ...
AMER CHEMICAL SOC2022Light absorption by brown carbon over the South-East Atlantic Ocean
Biomass burning emissions often contain brown carbon (BrC), which represents a large family of light-absorbing organics that are chemically complex, thus making it difficult to estimate their absorption of incoming solar radiation, resulting in large uncer ...
COPERNICUS GESELLSCHAFT MBH2022Similarities and Differences among Protein Dynamics Studied by Variable Temperature Nuclear Magnetic Resonance Relaxation
David Lyndon Emsley, Jayasubba Reddy Yarava, Andrea Bertarello, Baptiste Busi, François Freymond
Understanding and describing the dynamics of proteins is one of the major challenges in biology. Here, we use multifield variable-temperature NMR longitudinal relaxation (R-1) measurements to determine the hierarchical activation energies of motions of fou ...
AMER CHEMICAL SOC2021Investigation of the heterogeneously catalysed gas phase CO2 hydrogenation reaction: Development of analysis methods and reaction analysis on pristine metal catalysts
Robin Tobias Andreas Mutschler
The aim of this thesis is to contribute to the development of analysis methods that enable an improved investigation of the CO2 hydrogenation reaction such as quantitative mass spectrometry and infrared thermography. Furthermore, the contribution is in the ...
EPFL2019Design and characterization of variable stiffness structural joints
This paper presents design and characterization of a new type of structural joint which can vary its stiffness through actuation. Stiffness variation is employed to control the dynamic response of frame structures equipped with such joints. The joint is ma ...
2019CHD3 Dissociation on the Kinked Pt(210) Surface: A Comparison of Experiment and Theory
Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick
To be able to simulate activated heterogeneously catalyzed reactions on the edge and corner sites of nanoparticles, a method for calculating accurate activation barriers for the reactions is required. We have recently demonstrated that a semiempirical spec ...
2019Quantum-state-controlled channel branching in cold Ne(3P2)+Ar chemi-ionization
Andreas Osterwalder, Sean Dennis Steven Gordon, Junwen Zou, Silvia Tanteri
A prerequisite to gain a complete understanding of the most basic aspects of chemical reactions is the ability to perform experiments with complete control over the reactant degrees of freedom. By controlling these, details of a reaction mechanism can be i ...
2018Incident Angle Dependence of CHD3 Dissociation on the Stepped Pt(211) Surface
Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick
The dissociation of methane on transition metal surfaces is not only of fundamental interest but also of industrial importance as it represents a rate-controlling step in the steam-reforming reaction used commercially to produce hydrogen. Recently, a speci ...
2018CO2 hydrogenation reaction over pristine Fe, Co, Ni, Cu and Al2O3 supported Ru: Comparison and determination of the activation energies
Noris André Gallandat, Emanuele Moioli, Wen Luo, Robin Tobias Andreas Mutschler
Fe, Co, Ni and Cu are the main non-noble industrially significant catalysts in the CO2 and CO gas phase hydrogenation reaction towards hydrocarbons and alcohols. These catalysts are typically supported on metal oxides such as SiO2, TiO2, Al2O3 and ZnO, in ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2018Mechanical Stress Combined with Alloying May Allow Continuous Control Over Reactivity: Strain Effects on CO Dissociation and Subsequent Methanation Catalysis over Ni(211), Ni3Fe(211), and NiFe(112)
William Curtin, Michael Frederick Francis
Mechanical stress combined with alloying as controlled by CO dissociation is investigated for the control of methanation activity. CO dissociation over strained Ni(211), Ni3Fe(211), and NiFe(112) is investigated. A continuous 0.62 eV range of CO reaction e ...
