Phototransformation kinetics of cyanobacterial toxins and secondary metabolites in surface waters

Sandro Marcotullio

Background Cyanobacteria and their toxins occur in high concentrations during the so-called bloom events in surface waters. To be able to assess the risks associated with cyanobacterial blooms, we need to understand the persistence and fate processes of th ...

Motility-Induced Microphase and Macrophase Separation in a Two-Dimensional Active Brownian Particle System

Pasquale Digregorio

As a result of nonequilibrium forces, purely repulsive self-propelled particles undergo macrophase separation between a dense and a dilute phase. We present a thorough study of the ordering kinetics of such motility-induced phase separation (MIPS) in activ ...

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 ...

Influence of thermo-mechanical history on the ordering kinetics in 18 carat Au alloys

Helena Van Swygenhoven, Steven Van Petegem, Nadine Baluc, Marina Garcia Gonzalez

Precious alloys are subjected to a series of mechanical and thermal operations during manufacturing. For 18 carat gold alloys the processing operations can induce L1(0) ordered nanodomains, known to lead to the buildup of residual stresses, which are the p ...

Development of Tissue Kallikrein Inhibitors for the Treatment of Netherton Syndrome

Patrick Andreas Gonschorek

There is currently no approved treatment for Netherton syndrome, which is a severe, genetic skin disease characterized by chronic inflammation and excessive peeling of the skin. Even though the molecular disease mechanism has been assigned to the unopposed ...

Mechanism and Kinetics of Propane Dehydrogenation and Cracking over Ga/H-MFI Prepared via Vapor-Phase Exchange of H-MFI with GaCI3

Matthieu Bondil

In this study, the mechanism and kinetics of C3H8 dehydrogenation and cracking are examined over Ga/H-MFI catalysts prepared via vapor-phase exchange of H-MFI with GaCl3. The present study demonstrates that GaH cations are the active centers for C3H8 ...

Laser flash photolysis study of the photoinduced oxidation of 4-(dimethylamino)benzonitrile (DMABN)

Urs von Gunten, Frank Jonathan Leresche, Silvio Canonica

Aromatic amines are aquatic contaminants for which phototransformation in surface waters can be induced by excited triplet states of dissolved organic matter ((DOM)-D-3*). The first reaction step is assumed to consist of a one-electron oxidation process of ...

The Structure of the Cobalt Oxide/Au Catalyst Interface in Electrochemical Water Splitting

Klaus Kern

The catalytic synergy between cobalt oxide and gold leads to strong promotion of the oxygen evolution reaction (OER)one half-reaction of electrochemical water splitting. However, the mechanism behind the enhancement effect is still not understood, in part ...

Acylated heptapeptide binds albumin with high affinity and application as tag furnishes long-acting peptides

Christian Heinis, Alessandro Zorzi, Jonas Alfred Karl Wilbs, Simon Jan Middendorp

The rapid renal clearance of peptides in vivo limits this attractive platform for the treatment of a broad range of diseases that require prolonged drug half-lives. An intriguing approach for extending peptide circulation times works through a 'piggy-back' ...
