Identification of composite power quality disturbances based on relative position matrix

Frontiers in Energy Research
With the integration of large-scale nonlinear loads and distributed power sources into the grid, composite power quality disturbances (PQDs) events are becoming increasingly common, which significantly degrade the quality of power supply. Therefore, this

Removal of methylene blue and mechanism on magnetic γ-Fe2O3/SiO2 nanocomposite from aqueous solution

Water Resources and Industry, 2016
Magnetic γ-Fe2O3/SiO2 (M-γFS) nanocomposite was prepared using γ-Fe2O3 as the magnetic carriers. M-γFS was characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), and Fourier Transform infrared spectroscopy (FTIR).
