UV-irradiation provokes generation of superoxide on cell wall polygalacturonic acid
(Wiley, Hoboken, 2013)
We examined the redox effects of UV irradiation on cell wall isolates from Pisum sativum leaves, and polygalacturonic and galacturonic acid, in the presence of hydrogen peroxide. For this purpose, electron paramagnetic ...
Variations in polyamine conjugates in maize (Zea mays L.) seeds contaminated with aflatoxin B1: a dose-response relationship
(Wiley, Hoboken, 2020)
BACKGROUND Cereal seeds, such as maize seeds, are frequently contaminated with aflatoxin B1 (AFB1), one of the most dangerous naturally occurring carcinogens. In plants, phenolamides are involved in biotic stress response. ...
Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Elsevier Science Sa, Lausanne, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
