Issue date:August 2, 2011 Publication year:2011 Pages:1700-1709 Language:English ISSN:10221352 E-ISSN:15213935 CODEN:MCHPES Document type:Journal article (JA) Publisher:Wiley-VCH Verlag, P.O. Box 101161, Weinheim, D-69451, Germany Abstract:The selective localization of carbon nanotubes (CNTs) in an immiscible polymer blend has attracted much attention. If the two component polymers could react with each other, do selectively located CNTs affect those reactions? Here, an immiscible polyester blend based on polycarbonate/poly(trimethylene terephthalate) (PC/PTT) is studied. CNTs introduced during melt mixing are selectively located in the PTT phase and on the phase interface during the middle stage of melt mixing. The interface-located CNTs can act as additional substrate to catalyze or even participate in the transesterification themselves, homogenizing the phase morphology of the matrix blend. The degree of randomness of the composite systems is increased, accompanied by a reduced number-average length of the copolymer sequences. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:The adsorptive capability of β-Cyclodextrin-cross-linked polymer(β-CDCP) for cadmium was assessed in this work using column method. It was found that the complex (Cd(II)-5-Br-PADAP) could be quantitatively retained on the β-CDCP in the pH 8.5, eluted completely with 1.5 mol·L-1 HCl. Under the optimum conditions, the linear range, detection limit (DL) and the relative standard deviation (R.S.D.) was 2.0-60.0 μg·L-1, 7.8 ng·L-1 and 2.20% (n=3, c=20.0 μg·L-1) respectively. The separation of Cd(II) was achieved from water samples with an enhancement factor of 20. Moreover, the β-CDCP could be used repeatedly and offered better recovery. The method was validated using a certified reference material, and applied for the determination of trace cadmium in water samples. © (2011) Trans Tech Publications, Switzerland.

Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:The invert arch floor of large plunge pool is composed of some discrete arch blocks divided by construction joints. The joint is only 1 mm wide. Under the uplift pressure, the mechanical behavior belongs to highly nonlinear problem, which is difficult to simulate by finite element method. Based on NMM (numerical manifold method), the kinematic motion process of the invert arch floor is simulated under the different uplift pressure. Calculation results show that: as the uplift pressure increasing, each arch block gradually rises, rotates, contacts with adjacent blocks and the expansion joint width between adjacent blocks reduces. When uplift pressure reaches 85Kpa, the mutation of expansion joint width emerges and the invert arch floor finishes self-lock process which indicating the invert arch floor start playing statically indeterminate role to keep stable. The bearing capacity of the floor is determined by concrete compressive strength and anchoring strength of two arch abutments. © (2011) Trans Tech Publications.
