Heterogeneous catalysis via light-heat dual activation: A path to the breakthrough in C1 chemistry
A hybrid photothermal catalytic system, which combines both the photochemical (light) and thermal (heat) activation pathways over a bifunctional catalyst, has demonstrated remarkable levels of reaction activity and selectivity when compared with individual ...
Cell Press2024Kinetic Network Modeling of the Catalytic Upgrading of Biomass's Acetate Fraction to Aromatics
Jeremy Luterbacher, Jher Hau Yeap, Bartosz Rozmyslowicz, Ahmed Mohamed Ibrahim Elkhaiary
The acetate fraction is the fourth most abundant fraction by weight in many plant species and can be easily extracted as acetic acid in high yields. We have previously shown that acetic acid obtained from steam pretreated beech wood could be upgraded in a ...
Washington2023Development of next-generation microfluidic systems for enhanced, faster, and cost-effective immunoassays for tissue diagnostics - Ac electrothermal flow & Acoustofluidics
The application of microfluidics in the field of surface-based assays and more specifically, the spatial molecular profiling of tumor tissues has gained a lot of interest, especially with the increased interest in personalized medicine and targeted therapy ...
EPFL2023Evaluation of the role of superoxide radical as chain carrier for the formation of hydroxyl radical during ozonation
Urs von Gunten, Yan Wang, Gang Yu
Superoxide radicals (O-2(center dot-)) have been suggested as an important chain carrier in the radical chain reaction that promotes ozone (O-3) decomposition to hydroxyl radicals ((OH)-O-center dot) during ozonation. However, due to the difficulty in meas ...
PERGAMON-ELSEVIER SCIENCE LTD2023Improving time-resolution and sensitivity of in situ X-ray photoelectron spectroscopy of a powder catalyst by modulated excitation
Davide Ferri, Oliver Kröcher, Filippo Buttignol
Ambient pressure X-ray photoelectron spectroscopy (APXPS) is a powerful tool to characterize the surface structure of heterogeneous catalysts in situ. In order to improve the time resolution and the signal-to-noise (S/N) ratio of photoemission spectra, we ...
ROYAL SOC CHEMISTRY2023One-pot synthesis of functionalized bis(trifluoromethylated)benziodoxoles from iodine(i) precursors
Jérôme Waser, Xingyu Liu, Nieves Pilar Ramirez Hernandez, Tobias Michael Milzarek
Bis(trifluoromethylated)benziodoxoles (Bx) are broadly used cyclic hypervalent iodine reagents due to their stability and unique chemical properties. However, current methods to access them require several steps and long reaction times, making their synthe ...
2023Autocatalysis and CO2: Carbon Capture and Utilization (CCU) Meets Natural Processes
Paul Joseph Dyson, Jorge Gustavo Uranga, Martin Hulla, Gabriela Gastelu
Autocatalytic reactions were proposed to play a key role at the beginning of life starting from the first reduction of CO2 to formate, acetate and C-1-C-4 hydrocarbons. In carbon capture and utilization (CCU) processes, the same reactions were demonstrated ...
Weinheim2023The influence of sulfate addition on hydration kinetics and C-S-H morphology of C3S and C3S/C(3)A systems
Karen Scrivener, Franco Alberto Zunino Sommariva
A comprehensive understanding of hydration kinetics, sulfate requirement and phase assemblage of Portland cement is crucial for further optimization of early-age performance, especially when part of cement is replaced by mineral additions in blended cement ...

Karen Scrivener, Franco Alberto Zunino Sommariva, Mohsen Ben Haha, François Henri Avet, Anuj Parashar, Yuvaraj Dhandapani, Sreejith Krishnan
The RILEM technical committee 282-CCL: Calcined Clays as Supplementary Cementitious Materials, investigates all the aspects related to calcined clays, from clay exploration and characterization to calcination process, hydration reactions and concrete prope ...
SPRINGER2022Construction of Fe3O4 bridged Pt/g-C3N4 heterostructure with enhanced solar to fuel conversion
Michael Graetzel, Shaik Mohammed Zakeeruddin
In this study, we report the effects of co-catalysts of Pt nanoparticles and Fe3O4 clusters on photocatalytic behaviors of g-C3N4 (CN) and the use of the resulting photocatalyst for CO2 photoreduction to solar fuels in a flow reactor operated at room-tempe ...
