Pergamon-Elsevier Science Ltd2024Squalene Depletion in Skin Following Human Exposure to Ozone under Controlled Chamber Conditions
A major component of human skin oil is squalene, a highly unsaturated hydrocarbon that protects the skin from atmospheric oxidants. Skin oil, and thus squalene, is continuously replenished on the skin surface. Squalene is also quickly consumed through reac ...
Amer Chemical Soc2024Characterization of low-temperature plasmas generated by dielectric barrier discharges for bacterial inactivation
Low-temperature plasmas (LTPs) at atmospheric pressure hold great promise for disinfection and sterilization applications. When compared to traditional sterilization technologies like autoclaving, LTPs may offer several benefits, including reduced energy c ...
EPFL2024Modelling the coupled mercury-halogen-ozone cycle in the central Arctic during spring
Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot, Jenny Thomas
Near-surface mercury and ozone depletion events occur in the lowest part of the atmosphere during Arctic spring. Mercury depletion is the first step in a process that transforms long-lived elemental mercury to more reactive forms within the Arctic that are ...
2023Electron probing of oxygen-evolving oxide catalysts
Water splitting is one of the cleanest ways to store energy. The production of hydrogen and oxygen gases can be utilized in fuel cells to generate electricity, power, and heat. In the water splitting process, the oxygen evolution reaction (OER), taking pla ...
EPFL2022Optical properties and photochemical production of hydroxyl radical and singlet oxygen after ozonation of dissolved organic matter
Urs von Gunten, Frank Jonathan Leresche
This study focuses on the effects of ozonation on the optical and photochemical properties of dissolved organic matter (DOM). Upon ozonation, a decrease in light absorption properties of DOM was observed concomitantly with a large increase in singlet oxyge ...
ROYAL SOC CHEMISTRY2021The Indoor Chemical Human Emissions and Reactivity (ICHEAR) project: Overview of experimental methodology and preliminary results
With the gradual reduction of emissions from building products, emissions from human occupants become more dominant indoors. The impact of human emissions on indoor air quality is inadequately understood. The aim of the Indoor Chemical Human Emissions and ...
WILEY2020Statistical methods for accounting and understanding ozone trends derived from observations
Emissions of ozone precursors have been regulated in Europe since around 1990 with air quality control measures, which resulted in reductions of nitrogen oxides and volatile organic compounds concentrations. In order to understand how these measures have a ...
EPFL2020Temporal and spatial analysis of ozone concentrations in Europe based on timescale decomposition and a multi-clustering approach
Satoshi Takahama, Eirini Boleti, Christoph Hueglin
Air quality measures that were implemented in Europe in the 1990s resulted in reductions of ozone precursor concentrations. In this study, the effect of these reductions on ozone is investigated by analyzing surface measurements of this pollutant for the t ...
2020Molecular-Level Transformation of Dissolved Organic Matter during Oxidation by Ozone and Hydroxyl Radical
Ozonation of drinking and wastewater relies on ozone (O-3) and hydroxyl radical ((OH)-O-center dot) as oxidants. Both oxidants react with dissolved organic matter (DOM) and alter its composition, but the selectivity of the two oxidants and mechanisms of re ...
