Autor: Hayat Zerrouki, Virginie Rizzati, Corinne Bernis, Anne Nègre-Salvayre, Jean Philippe Sarrette, Sarah Cousty
Publikováno v: PLoS ONE, Vol 10, Iss 3, p e0116083 (2015)
Lipid A is a major hydrophobic component of lipopolysaccharides (endotoxin) present in the membrane of most Gram-negative bacteria, and the major responsible for the bioactivity and toxicity of the endotoxin. Previous studies have demonstrated that t

Publikováno v: Physica Scripta. 97:125608
The spatial and temporal evolution of the ozone density has been measured in a 1 cm electrode gap tip to plane positive pulsed corona discharge in air at atmospheric pressure with no gas flow. It was expected to observe a higher ozone density in the
