Large-scale solar photovoltaic (PV) power plants tend to be set in desert areas, which enjoy high irradiation and large spaces. However, due frequent sandstorms, amounts of contaminants dirt are suspended the air deposited on modules, greatly decreases efficiency service life. To clean PV improve efficiency, many methods were proposed. It was found that application self-cleaning coating modules...

abstract among synthetic carriers, dendrimers with the more flexible structure have attracted a great deal of researchers' attention in the field of gene delivery. followed by the promising results upon hydrophobic modification on polymeric structures in our laboratory, alkylcarboxylated poly (propylenimine)-based carriers were synthesized by nucleophilic substitution of amines with alkyl moiet...
