The refractive index (n) and thermo-optic coefficient (dn/dT) of the CAPU were measured at 650 nm wavelength and different temperature by attenuated total reflection (ATR) technique. By using CCD digital imaging devices, transmission loss of CAPU was measured and the value

is 0.565dB/cm. The results will provide the foundation for many potential applications such as digital thermo-optic switch materials and other fields in the future. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 2567-2572, 2011″
“BiFeO(3) (BFO) and 4 wt. % Al-doped ZnO (ZAO) layers were grown on indium tin oxide (ITO) glass substrate using a pulsed laser deposition (PLD) method. I-V curves of Selleck LY2835219 the ZAO/BFO/ITO glass structure were investigated over the temperature range from 60 to 240 K. Analysis of the leakage current demonstrates that Poole-Frenkel emission is the dominant mechanism in our sample. The relations between resistance and temperature at positive and negative bias voltages are different, and the difference arises from the ferroelectric switching in BFO and the interfacial depletion layer between Stem Cell Compound Library research buy the semiconducting and the ferroelectric layers. Magnetoresistance (MR) effect is observed and the negative MR is related to the electron spin-dependent scattering and the interface resistance of the heterostructure.

“A

biologically active diacid monomer, 5-(2-phthalimidoethanesulfonamido) isophthalic acid (6), based on taurine, was easily prepared in three steps. Also a series of novel biologically active polyesters (PE)s were synthesized by the reaction of this monomer with several aromatic diols by step growth polymerization using tosyl chloride (TsCl)/dimethylformamide (DMF)/pyridine (Py) system as a condensing agent. The resulting new polymers were obtained in good to high yields with moderate inherent viscosities. All of the PEs were

characterized by FTIR and some of them were also characterized by H-1-NMR and elemental analyses methods. The thermal stability of PEs was evaluated with thermogravimetric analysis and differential scanning calorimetry techniques under a nitrogen atmosphere and it was found that they have moderate stability. Wheat seedlings were normally grown in KPT-8602 cost the presence of 6 and it’s derived PEs in soil. Also the high dehydrogenase activities in treated soils with obtained compounds showed biodegradability of polymers under soil burial in natural environments. It can be concluded that the synthesized compounds derived from taurine are possibly biologically active and environmentally nontoxic for soil microorganisms. (C) 2011 Wiley Periodicals, Inc.
