Optical properties and plasmon – Two different phonons coupling in ZnGeAs2 + Mn
(Journal of Alloys and Compounds, 2013)
Optical properties of p-type Zn1−xMnxGeAs2 for 0 ⩽ x ⩽ 0.078 were investigated by Raman spectroscopy at room temperature. Phonons of ZnGeAs2 are experimentally determined and they are in excellent agreement with those ...
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 ...
