The ozonization at the vacancy defect site of the single-walled carbon nanotube has been studied by static quantum mechanics and atom-centered density matrix propagation based ab initio molecular dynamics within a two-layered ONIOM approach. Among five different reaction pathways at the vacancy defect, the reaction involving the unsaturated active carbon atom is the most probable pathway, where...
by Rieche et al. (1). These compounds are also referred to as monomeric ozonides, but this terminology appears to be a misnomer. Hence, the term ozonide is used for “true ozonides” in the present study. During the course of our studies, Schroder (2 ) reported the formation of cisand trans-isomeric ozonides on the ozonization of cis-di-t-butylethylene. Only the trans-isomer was detected on the o...
Abstract Background Biochar ozonization was previously shown to dramatically increase its cation exchange capacity, thus improving nutrient retention capacity. The potential soil application of ozonized biochar warrants the need for a toxicity study that investigates effects on microorganisms. Results In presented here, we found filtrates collected from pine 400 and rogue did not have any inhib...
An ozonization system (Ozomax OZO 6VTT, IGT limited, Ontario, Canada) was installed in a commercial plastic-covered greenhouse in Danville, Quebec, Canada (www.savoura.com) to study the effects of the disinfection and recirculation of the nutrient solution in a tomato crop. The ozonization system was compared to a conventional growing system where the nutrient solution was not treated, neither ...
The impact of ozone dose and time ozonization on the selected physicochemical properties Agaricus bisporus stored for 14 days in 2 °C was investigated. Mushrooms were subjected to gaseous with increasing concentrations 0.5, 1.0, 2.0 mg L−1 applied two times ozonization: 30 60 min. following parameters evaluated: weight loss, internal external color L*a*b* parameters, overall change (ΔE), browni...
