Reusable Nanostencils for Creating Multiple Biofunctional Molecular Nanopatterns on Polymer Substrate

In this paper, we demonstrate a novel method for high throughput patterning of bioprobes with nanoscale features on biocompatible polymer substrate. Our technique, based on nanostencil lithography, employs high resolution and robust masks integrated with a ...

Fate of the pathogen indicators phage phiX174 and Ascaris suum eggs during the production of struvite fertilizer from source-separated urine

Tamar Kohn, Brian Pecson, Loïc Decrey, Kai Udert

Human urine has the potential to be a sustainable, locally and continuously available source of nutrients for agriculture. Phosphate can be efficiently recovered from human urine in the form of the mineral struvite (MgNH4PO4•6H2O). However, struvite format ...

Reuse of domestic wastewater treated in macrophyte ponds to irrigate tomato and eggplant in semi-arid West-Africa: benefits and risks

André Mermoud

The scarcity of freshwater resources is a critical problem in semi-arid zones and marginal quality water is increasingly being used in agriculture. This paper aimed at evaluating the physico-chemical and biological risks on irrigated soils and fruits of ma ...

Spatial and temporal presence of a wastewater-derived micropollutant plume in Lake Geneva

Tamar Kohn, Florence Bonvin, Rebecca Rutler

This study discusses the occurrence and environmental risk associated with a micropollutant plume originating from the direct discharge of treated wastewater into the Vidy Bay of Lake Geneva, Switzerland. The temporal variations and spatial extent of the p ...

Information and Communication Technology for Industrial Symbiosis

Guillaume Bastien Massard

Industrial symbiosis describes the mutualistic interaction of dif- ferent industries for beneficial reuse of waste flows or energy cascading that results in a more resource-efficient production system and fewer adverse environmental impacts. Research shows ...

Ferrate (Fe(VI)) Application for Municipal Wastewater Treatment: A Novel Process for Simultaneous Micropollutant Oxidation and Phosphate Removal

Urs von Gunten, Yun Ho Lee

A novel technology for enhanced municipal wasterwater treatment was assessed based on the dual functions of Fe(VI) to oxidize micropollutants and remove phosphate by formation of ferric phosphates. Second-order rate constants (k) for the reactions of selec ...

A Document Reuse Tool for Communities of Practice

Stéphane Sire, Micaël Paquier, Christine Vanoirbeek, Aïda Boukottaya, Loïc Merz

Virtual communities of practice are gaining importance as mean of sharing and exchanging knowledge. In such environments, information reuse is of major concern. In this paper, we outline the importance of structuring documents in order to facilitate the re ...

Ozonation of Source-Separated Urine for Resource Recovery and Waste Minimization: Process Modeling, Reaction Chemistry, and Operational Considerations

Urs von Gunten

Bench-scale, semibatch experiments were performed to examine physical-chemical constraints on ozone (O-3) absorption and micropollutant oxidation during ozonation of source-separated hydrolyzed urine and the concentrate and diluate streams produced via ele ...
