According to the relationship of coordinated interaction between unit output and electricity price, an economic/risk/environmental generation optimal model for maximizing total profits in the dealing day and minimizing both risk and emissions was formulated in this paper. A new multi-objective differential evolution optimization algorithm, which integrated Pareto non-dominant sorting and differential...
In recent years, combining a ferroelectric ceramic and a polymer matrix to form a flexible composite with coupling properties in between that of two individual phases has been pursued for sensors in medical applications and hydrophones. For hydrophone applications, a useful piezoelectric material should have high piezoelectric voltage coefficient (g33), piezoelectric strain coefficient (d33) and high...
Bi25FeO40 powders have successfully been synthesized by simple hydrothermal method. The effect of the concentration of mineralizer and stoichiometry on the prepared samples was investigated. With the UV-Vis spectra, Bi25FeO40 powders have a broad absorption band in the range of 400-600 nm and a good visible-light-response ability. Photo-catalytic activity of Bi25FeO40 powders was evaluated by the...
