Using continuous electrical conductivity measurements to derive major solute concentrations in karst systems

Hydrochemical data of karst springs provide valuable insights into the internal hydrodynamical functioning of karst systems and support model structure identification. However, the collection of high-frequency time series of major solute species is limited ...

Generalised Kerr Microcomb Physics in Synchronously Driven Systems

Miles Henry Anderson

In this thesis, the generation of microcombs under complex, non-trivial, and/or higher-order cavity conditions is explored, both in theory & simulation, and in practical experimentation. Pulse-driving of microresonators is investigated for the generation ...

A method for the reliable and reproducible precipitation of phase pure high Ca/Si ratio (>1.5) synthetic calcium silicate hydrates (C-S-H)

Karen Scrivener, Paul Bowen, Maya Nicole Harris, Grace Simpson

Various methods have been developed to synthesize C-S-H; however, these methods have only allowed for the successful production of pure-phase C-S-H with Ca:Si of 1.5 or less. Attempts to form higher Ca:Si ratios by these methods gives C-S-H (Ca:Si 1.5 or l ...

A Simulation-Based Heuristic to Find Approximate Equilibria with Disaggregate Demand Models

Michel Bierlaire, Virginie Janine Camille Lurkin, Stefano Bortolomiol

Oligopolistic competition occurs in various transportation markets. In this paper, we introduce a framework to find approximate equilibrium solutions of oligopolistic markets in which demand is modeled at the disaggregate level using discrete choice models ...

Micropollutants as internal probe compounds to assess UV fluence and hydroxyl radical exposure in UV/H 2 O 2 treatment

Urs von Gunten, Silvio Canonica, Fabienne Eugster, Robin Wünsch, Thomas Wintgens

Organic micropollutants (MPs) are increasingly detected in water resources, which can be a concern for human health and the aquatic environment. Ultraviolet (UV) radiation based advanced oxidation processes (AOP) such as low-pressure mercury vapor arc lamp ...

Enhanced transformation of aquatic organic compounds by long-lived photooxidants (LLPO) produced from dissolved organic matter

Urs von Gunten, Silvio Canonica, Stephanie Christa Remke

Dissolved organic matter (DOM) plays a crucial role in the photochemical transformation of organic contaminants in natural aquatic systems. The present study focuses on the characterization of a specific effect previously observed for electron-rich phenols ...

Improved Modeling of Sediment Oxygen Kinetics and Fluxes in Lakes and Reservoirs

Alfred Johny Wüest

To understand water quality degradation during hypoxia, we need to understand sediment oxygen ﬂuxes, the main oxygen sink in shallow hypolimnia. Kinetic models, which integrate diﬀusion and consumption of dissolved oxygen (DO) in sediments, usually assume ...

Thermodynamics and kinetics of protonated merocyanine photoacids in water

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Daniel Maria Busiello, Euro Solari, Cristian Pezzato, Stefano Zamuner, Cesare Berton

Metastable-state photoacids (mPAHs) are chemical species whose photo-activated state is long-lived enough to allow for proton diffusion. Liao's photoacid (1) represents the archetype of mPAHs, and is being widely used on account of its unique capability to ...

The effect of SO2 on the Ni-YSZ electrode of a solid oxide electrolyzer cell operated in co-electrolysis

Jan Van Herle, Stefan Diethelm, Guillaume Jeanmonod

In this work, the effect of sulphur poisoning of the Ni-YSZ electrode of an SOEC operated in co-electrolysis mode was investigated. Short-term tests with exposure up to 5 ppmv of SO2 were performed at OCV and under polarization (0.25 A cm−2). The two-stage ...

Effect of the Solvent on the Oxygen Evolution Reaction at the TiO2-Water Interface

Alfredo Pasquarello, Francesco Ambrosio, Patrick Gono

We investigate the solvation effect of water on the overpotentials of the oxygen evolution reaction on rutile TiO2 by applying the thermodynamic integration method on atomistic model interfaces with and without the water molecules. We compare the results a ...
