Polyethersulfone(PES) microporous membrane was grafted with methacrylic acid under electron beam irradiation. Controlling the monomer concentration or the absorbed dose, the relationships of the degree of grafting with the monomer concentration and the absorbed dose were obtained for optimum the monomer concentration and absorbed dose. The grafted membrane was characterized by FT-IR and SEM, and the hydrophilicity contact angle of the membrane was tested. Source

Dense and highly ordered TiO2 nanotube arrays (TiNT) were fabricated by electrochemical anodic oxidation method, and doped with Zn by MEVVA ion implantation. The surface morphology was characterized by scanning electron microscope. Photoelectric efficiency of the doped TiNT samples under UV and visible light excitation was studied. Theoretical study of anatase TiO2 doped with Zn was carried out by the LAPW method based on density functional theory. Source
