Study on Nanocomposite Membranes with Enhanced Performance for Forward Osmosis Ning MA1,a, Cao LIU1,b, Peijing WANG1,c and Chuyang TANG2,d 1Beijing Water Science and Technology Institute, Beijing 100048, China 2Department of Civil Engineering, The University of Hong Kong, Pokfulam, Hong Kong, China aningmabhri@gmail.com, blc@bwsti.com, cwpj@bwsti.com, dtangc@hku.hk Keywords: Nanocomposite; Forward Osmosis; Zeolite Nanomaterials; Polyamide; Polysulfone Abstract: Nanocomposite membranes with enhanced performance were investigated for forward osmosis (FO) by incorporation of nanoporous materials.
Besides the optimization on the interfacial polymerization of the polyamide layer and phase inversion of the porous support layer, embedding porous materials in a polymeric matrix may significantly enhance membrane properties such as permeability, selectivity, stability, surface area, or catalytic activity in various membrane processes.

The ionic potential of alkaline oxide is low, which will lower the ash melting point, while that of acid oxide is high, which will improve the ash melting point [[] Gui-rong LI: Journal of Shenyang Institute of Aeronautical Engineering, 2009, In Chinese. ], so that the ash melting point of cornstalk is obviously lower than that of lean coal ash.
Furthermore, KCl will also react with aluminosilicate from coal ash [[] Montgomery M, Vilhelmsen T and Jensen S A: Materials and Corrosion, Vol.59(2008), p. 783~793. ], resulting in the release of HCl, which will cause active oxidation corrosion to the high temperature superheater.

Introduction Among conducting polymers, polyaniline (PANI) is a promising material for commercial applications, because of its environmental stability, good process ability, and relatively low cost.
The use of PANI blends(composites) as anticorrosion coatings had been explored as the potential candidates to replace the chromium-containing materials, which have adverse health and environmental concerns.

The rare-earth (RE) doping of Si and Si-related materials [1-5] in the last years has been extensively studied for the development of light-emitting devices in the Si-based optoelectronics initiated by the reports on the photoluminescence (PL) and electroluminescence (EL) centered at around 1.54 μm of Er3+ (4I13/2→4I15/2) in Si [6].
As for RE doped materials, much attention has been paid to the Er doped silicon, because its characteristic emission at 1.54 μm is occurring in the minimum absorption of optical fibers.
The implantations of ions were performed on an ion implanter at the Institute of Semiconductors, Chinese Academy of Science.
