In Situ X‐ray Absorption Spectroscopy to Study the Dehydrogenation and Decomposition Mechanisms of an Iridium Pincer Catalyst Exposed to Gaseous Isopropanol

ChemCatChem, EarlyView.
This study identifies the intermediary structures for dehydrogenation of iPrOH for hydrogen gas production, circumvention of catalyst poisoning, and heat degradation pathway of (POCOP)‐Ir pincer catalyst, using in situ X‐ray absorption spectroscopy. Abstract On‐site hydrogen gas production from hydrogen‐rich liquids offers a clean alternative to fossil

Characterization of the reactive flow field dynamics in a gas turbine injector using high frequency PIV [PDF]

arXiv, 2008
The present work details the analysis of the aerodynamics of an experimental swirl stabilized burner representative of gas turbine combustors. This analysis is carried out using High Frequency PIV (HFPIV) measurements in a reactive situation. While this information is usually available at a rather low rate, temporally resolved PIV measurements are ...

Charting the landscape of the environmental exposome

iMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push

Transient temperature calculation method for complex fluid-solid heat transfer problems with scattering boundary conditions [PDF]

arXiv, 2018
A calculation method for engine temperatures is presented. Special focus is placed on the transient and scattering boundary conditions within the combustion chamber, including fired and coasting conditions, as well as the dynamic heat transfer of the water jacket.

Understanding and Comparing the Stability of Water‐ versus NMP‐Based Tin(IV)Sulfide Electrodes Using Post‐Mortem Analysis

ChemElectroChem, EarlyView.
This work investigates the degradation of SnS2 anodes for lithium‐ion batteries using CMC/SBR (water‐based) and PVDF (NMP‐based) binders. Post‐mortem analysis of electrodes at different states‐of‐health reveals changes in the bulk and surface of the active material.

Demonstrating the self-healing behaviour of some selected ceramics under combustion chamber conditions

, 2016
Closure of surface cracks by self-healing of conventional and MAX phase ceramics under realistic turbulent combustion chamber conditions is presented. Three ceramics namely; Al2O3, Ti2AlC and Cr2AlC are investigated. Healing was achieved in Al2O3 by even
