Surface DBD degradation in humid air, and a hybrid surface-volume DBD for robust plasma operation at high humidity

Alan Howling, Ivo Furno, Fabio Avino, Lorenzo Ibba, Alexandra Waskow

Surface dielectric barrier discharge performance deteriorates in humid air, with permanent and/or reversible degradation of its components. Plasma operation in a humid environment is unavoidable when humid air or water-containing materials are treated. Exp ...

Low-energy electron beam has severe impact on seedling development compared to cold atmospheric pressure plasma

Alexandra Waskow

Sprouts are germinated seeds that are often consumed due to their high nutritional content and health benefits. However, the conditions for germination strongly support the proliferation of present bacteria, including foodborne pathogens. Since sprouts are ...

Characterization of Efficiency and Mechanisms of Cold Atmospheric Pressure Plasma Decontamination of Seeds for Sprout Production

Alexandra Waskow

The consumption of fresh fruit and vegetable products has strongly increased during the past few decades. However, inherent to all minimally processed products is the short shelf life, and the risk of foodborne diseases, which have been increasingly relate ...
