Calcium sulphate dihydrate (gypsum) crystallization was studied under conditions, of supersaturation and temperature, simulating a brackish water desalination unit using solar energy. The effect of an commercial sodium salt of poly(acrylic acid), based compound known as RPI, on homogeneous nucleation and growth of gypsum was also examined. Gypsum was precipitated by mixing aqueous CaCl2 and Na2SO4 solutions. It was found that, with increasing temperature or supersaturation, the induction time decreases and the growth rate increases. By using classical nucleation theory, the interfacial tension and the nucleation rate values were estimated. It was shown that the interfacial tension is temperature dependent. The addition of increasing quantities of RPI, in the same conditions of temperature and supersaturation, prolongs the induction time, decreases the nucleation rate and increases the interfacial tension. The addition mode of RPI (in calcium or in sulphate solution) was found as an important parameter in controlling the inhibition process of gypsum crystallization. XRD and SEM analysis showed that RPI antiscalant strongly affected the texture and the morphology of the deposit gypsum. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) 相似文献

Complex perovskite oxides Ca2?xPrxMnO4 (x = 0–0.5) compounds were synthesized by a solid-state reaction technique. A tetra–ortho structural transition was observed. Impedance spectroscopy was used to study the electrical behavior in the frequency range 40 Hz–1 MHz and in the temperature range 80–350 K. Frequency-dependent conductivity spectra were found to obey the Jonscher's power law. Complex impedance plane plots have indicated that the dielectric response is mainly intrinsic. Materials bulk response was found to be dominated by non-localized or localized conduction, depending on temperature and frequency. 相似文献

Ever since the more than decade-old discovery of the mechanical exfoliation method for graphene isolation, this miraculous 2-dimensional material is still widely used in various applications because of its exceptional electron mobility and thermal conductivity. Graphene, commonly grown on a metallic substrate using chemical vapor deposition (CVD), needs to be transferred onto dielectric substrates compatible with complementary metal oxide–semiconductor (CMOS) technology for various electronic and optical applications. However, the ultra-clean transfer of graphene with defect-free is still crucial for large-area graphene devices' efficiency. This review introduces a comprehensive and up-to-date account of the transfer of the most attention kinds of CVD-grown graphene on copper substrates. The advances and main challenges of both wet and dry transfer methods are also carefully described. Particular emphasis is also given on graphene-based BioFET devices, revising their sensing mechanism and the optimum operational conditions toward high specificity and sensitivity. The authors have been convinced that upgrading the transfer process to accomplish the cleanest graphene surface and exploiting the optimum operating conditions will undoubtedly be of considerable significance to fabricate graphene-based devices. 相似文献

The first metal-free procedure for the synthesis of arylsulfonyl fluorides is reported. Under organo-photoredox conditions, aryl diazonium salts react with a readily available SO2 source (DABSO) to afford the desired product through simple nucleophilic fluorination. The reaction tolerates the presence of both electron-rich and -poor aryls and demonstrated a broad functional group tolerance. To shed the light on the reaction mechanism, several experimental techniques were combined, including fluorescence, NMR, and EPR spectroscopy as well as DFT calculations. 相似文献
