Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential

Urs von Gunten, Florian Frédéric Vincent Breider, Jun Ma, Yang Song

In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) ...

Self-Assembled Nanomicelles as MRI Blood-Pool Contrast Agent

Lothar Helm, Anne-Sophie Chauvin, Vassily Vorobiev

Gadolinium‐loaded nanomicelles show promise as future magnetic resonance imaging (MRI) contrast agents (CAs). Their increased size and high gadolinium (Gd) loading gives them an edge in proton relaxivity over smaller molecular Gd‐complexes. Their size and ...

Tuning the stacking behaviour of a 2D covalent organic framework through non-covalent interactions

Klaus Kern

Two-dimensional covalent organic frameworks (COFs) are crystalline porous materials composed of organic building blocks that are connected via covalent bonds within their layers, but through non-covalent interactions between the layers. The exact stacking ...

Phage Selection of Cyclic Peptides for Application in Research and Drug Development

Christian Heinis, Xudong Kong

Cyclic peptides can bind to protein targets with high affinities and selectivities, which makes them an attractive modality for the development of research reagents and therapeutics. Additional properties, including low inherent toxicity, efficient chemica ...

Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits

Rizlan Bernier-Latmani

Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U-(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U-(IV) ...

Effect of Fe(II)/Fe(III) species, pH, irradiance and bacterial presence on viral inactivation in wastewater by the photo-Fenton process: Kinetic modeling and mechanistic interpretation

César Pulgarin, Michaël Bensimon, Anna Carratala Ripolles, Stefanos Giannakis, Siting Liu

Advanced Oxidation Processes and in particular photo-Fenton, represent promising strategies of pathogen inactivation in wastewater effluents. Nevertheless, its full potential is not yet unlocked, as the efficacy of photo-Fenton against viruses has not been ...
