Characterization of low-temperature plasmas generated by dielectric barrier discharges for bacterial inactivation

Low-temperature plasmas (LTPs) at atmospheric pressure hold great promise for disinfection and sterilization applications. When compared to traditional sterilization technologies like autoclaving, LTPs may offer several benefits, including reduced energy c ...

Influence of Different Sterilization Methods on the Surface Chemistry and Electrochemical Behavior of Biomedical Alloys

Stefano Mischler, Brigitte Jolles-Haeberli, Anna Neus Igual Muñoz

Sterilization is a prerequisite for biomedical devices before contacting the human body. It guarantees the lack of infection by eliminating microorganisms (i.e., bacteria, spores and fungi). It constitutes the last fabrication process of a biomedical devic ...

Electrospun zein incorporating phycocyanin and Spirulina extract: Fabrication, characterization, and potential application

Niloufar Sharif

Electrospinning was used to develop zein fibers containing phycocyanin and aqueous-ethanolic extract of Spirulina (AEES) for elucidating the potent packaging properties of phycocyanin and AEES on walnut samples. Morphological results revealed that using th ...

Abatement of Polychoro-1,3-butadienes in Aqueous Solution by Ozone, UV Photolysis, and Advanced Oxidation Processes (O-3/H2O2 and UV/H2O2)

Urs von Gunten, Minju Lee, Silvio Canonica

The abatement of 9 polychloro-1,3-butadienes (CBDs) in aqueous solution by ozone, UV-C(254 nm) photolysis, and the corresponding advanced oxidation processes (AOPs) (i.e., O-3/H2O2 and UV/H2O2) was investigated. The following parameters were determined for ...

Solar disinfection of wild Salmonella sp. in natural water with a 18 L CPC photoreactor: Detrimental effect of non-sterile storage of treated water

César Pulgarin, Julian Andrés Rengifo Herrera, Frédéric Sciacca

For the first time solar disinfection of liters of water containing wild Salmonella sp. and total coliforms was carried out in a compound parabolic collector (CPC) photoreactor at temperatures of almost 50 degrees C. Using surface water with high turbidity ...

N-15 immobilization in forest soil: a sterilization experiment coupled with (15)CPMAS NMR spectroscopy

Claire Guenat, Isabelle Morier Jaquet

In temperate forests, soils are the main sink for atmospheric N deposition. The main processes proposed for N retention are microbial and abiotic immobilization in soil organic matter. The relative importance of these processes as well as the kind of resul ...

Liquid-core capsules as a tool in biotransformations

The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...
