Visible light plays a significant role during bacterial inactivation by the photo-fenton process, even at sub-critical light intensities

César Pulgarin, Stefanos Giannakis, Rosa Mosteo, David Muzard, Angelica Varon Lopez

The aim of this research is to clarify the contribution of sunlight wavelengths, irradiance and Fe2+/H2O2 during bacterial disinfection by the photo-Fenton process in clear surface waters. We considered different solar spectrum distributions (visible, UVA- ...

FuZZan: Efficient Sanitizer Metadata Design for Fuzzing

Mathias Josef Payer

Fuzzing is one of the most popular and effective techniques for finding software bugs. To detect triggered bugs, fuzzers leverage a variety of sanitizers in practice. Unfortunately, sanitizers target long running experiments-e.g., developer test suites-not ...

Improving visible light photocatalytic inactivation of E. coli by inducing highly efficient radical pathways through peroxymonosulfate activation using 3-D, surface-enhanced, reduced graphene oxide (rGO) aerogels

César Pulgarin, Stefanos Giannakis, Minoo Karbasi

In this work, we synthesized highly porous reduced graphene oxide foams, presenting augmented antibacterial activity in presence/absence of peroxymonosulfate (PMS). To date, this is the first investigation of photocatalytic PMS disinfection by 3D-rGO mater ...

Multi-sulfonated ligands on gold nanoparticles as virucidal antiviral for Dengue virus

Francesco Stellacci, Quy Ong Khac, Özgün Kocabiyik

Dengue virus (DENV) causes 390 million infections per year. Infections can be asymptomatic or range from mild fever to severe haemorrhagic fever and shock syndrome. Currently, no effective antivirals or safe universal vaccine is available. In the present w ...

Macrocycle synthesis strategy based on step-wise “adding and reacting” three components enables screening of large combinatorial libraries

Christian Heinis, Gerardo Turcatti, Julien Bortoli Chapalay, Alessandro Angelini, Alessandro Zorzi, Jonathan Patrice Vesin, Ganesh Kumar Mothukuri, Sangram Shivdas Kale, Carl Leonard Stenbratt

Macrocycles provide an attractive modality for drug development, but generating ligands for new targets is hampered by the limited availability of large macrocycle libraries. We have established a solution-phase macrocycle synthesis strategy in which three ...

Adaptation of waterborne echovirus to warm habitats enhances disinfection resistance

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann

Because of their high mutation rate, enteric virus populations excreted from a host are not clonal, but rather consist of a mutant cloud with many different genetic variants. Among these variants, the susceptibility to environmental stressors (e.g., temper ...

Unfolding the action mode of light and homogeneous vs. heterogeneous photo-Fenton in bacteria disinfection and concurrent elimination of micropollutants in urban wastewater, mediated by iron oxides in Raceway Pond Reactors

César Pulgarin, Florian Frédéric Vincent Breider, Dominique Grandjean, Stefanos Giannakis, Irene De La Obra Jimenez

In this work, iron oxides have been proposed as low-cost heterogeneous photo-Fenton catalysts for the simultaneous disinfection and reduction of microcontaminant load from urban wastewater in raceway pond reactors at near-neutral pH. The objective was not ...

Seasonal and spatial variation in total trihalomethane formation potential in groundwater in Tulkarm and Hebron, Palestine

Loay Awad

Water disinfection using processes such as chlorination is required to kill bacteria and harmful biological components. During chlorination, organic components in water react with chlorine, forming harmful disinfection by-products such as trihalomethanes ( ...

Determination of variables influencing the effectiveness of disinfection of surface water used for human consumption in Costa Rica

Clara Barret

Disinfection of water for human consumption is a challenge to ensure that water is free of pathogens and pollutants while avoiding the formation of potentially harmful undesirable products. The establishment of disinfection facilities must take into accoun ...

Relationship Between Inactivation and Genome Damage of Human Enteroviruses Upon Treatment by UV254, Free Chlorine, and Ozone

Tamar Kohn, Virginie Bachmann, Suzanne Marie Young, Jason Robert Torrey

Quantitative PCR (qPCR) is a convenient tool for monitoring virus concentrations in water and wastewater treatment trains, though it only informs about virus presence, but not infectivity. This limitation can be overcome if the relationship between infecti ...
