A two-parameter model for ion exchange process of ion-adsorption type rare earth oresPing Long1,2,Guanshi Wang3,Chao Zhang3,Ying Huang3,Sihai Luo31. School of Resources and Environmental Engineering... for the ion exchange process is key to creating a theoretical basis for the mining of ion-adsorption type rare earth ores.Ore samples from Xinfeng,Xunwu and Anyuan were used as the test ore samples......
Graphite-polypyrrole coated 316L stainless steel as bipolar plates for proton exchange membrane fuel cellsLi-jun Yang,Hai-jun Yu,Li-jun Jiang,Lei Zhu,Xu-yu Jian,and Zhong Wang Energy Materials... attractive as bipolar plates in proton exchange membrane fuel cells(PEMFC).In this study,graphite-polypyrrole was coated on SS 316L by the method of cyclic voltammetry.The surface morphology and chemical......
region. The characteristics of the transport behavior for aluminum doping were analyzed in terms of destroying the double exchange channel of Mn3+-O-Mn4+, distortion of the cell lattice and change of powder particles size and shape. Key words:magnetoresistance; metal-insulator transition; exchange interactions; transport property; rare earths; [全文内容正在添加中] ......

Key Laboratory of Advanced...)/perfluorosulfonic acid ion-exchange (PFSA) composite membranes as proton exchange membrane,sulfonic acid groups were grafted onto the surfaces of HSS via post grafting methods.TEM images and FT-IR spectra......
higher reduction potential. They exchange one electron during electrochemical reaction and have a higher proton diffusion coefficient. The mechanism of the electrode reaction is proton diffusion, and the proton diffusion coefficient is 5.67?10-10 cm2/s. Moreover, they reveal a higher discharge capacity than b-Ni(OH)2/b-NiOOH because they exchange one electron per nickel atom during charge......
