摘要:
<正>α-氨基膦酸酯作为天然α-氨基酸的含磷类似物,表现出广泛的生物活性。吡虫啉的问世,引起人们对新烟碱类杀虫剂研究的极大兴趣。人们在研究新烟碱类杀虫剂构效关系研究中发现:绝大部分高活性化合物都含有3-氨甲基吡啶基团。由于烟碱乙酰胆碱受体具有特定的空间结构,不同构型的杀虫剂与受体相互作用, 表现出不同的生物活性。基于此,我们采用活性基团拼接方法,设计并合成了一系列共19个含吡啶基的α-氨基

摘要:
In this paper, we prepared the nanocrystalline US films on the indium-doped tin oxide (ITO) glass substrates using a doctor-blade technique. The source US powder was first prepared by a hydrothermal method and then ground into a screen-printing paste by adding ethyl cellulose as a binder and terpineol as a solvent. The CdS samples were characterized by XRD, SEM, TEM, and UV-Vis diffuse reflectance spectroscopy. A photocurrent of 3.51 mA/cm, a fill factor of 0.44, an open circuit photovoltage of 0.50 V, and a conversion efficiency of 2.2% were obtained under a simulated solar illumination of 35 mW/cm(2), when the CdS film was annealed at 380 degrees C in air for 30 min. The maximum quantum efficiency of 5.5% was obtained at an incident wavelength of 500 nm. Our method provides a general way to prepare electrodes of metal chalcogenide nanocrystalline films.

摘要:
The 6-(4-alkoxycarbonylalkoxy)phenoxy-3-alkylthio-5-(fluoro-substituted)phenyl-l-phenylpyrazolo[3,4-d]pyrimidin-4-ones 6 have been successfully synthesized via a tandem aza-Wittig and annulation reactions of the corresponding iminophosphorances 4, aromatic isocyanate, and substituted phenols 2 in 59-69% isolated yields using actonitrile as solvent. These novel compounds 6 could be oxidized to sulfones 7 by hydrogen peroxide in satisfactory yields (57-93%). Their structures were clearly verified by spectroscopic data (IR, H-1 NMR, C-13 NMR, MS, Elemental analysis or X-ray diffraction crystallography). The results of preliminary bioassay indicated that these compounds possess herbicidal activity against the root of rape and barnyard grass. (c) 2006 Elsevier B.V. All rights reserved.

摘要:
Monodispersed porous crystalline TiO<inf>2</inf>, SrTiO<inf>3</inf>, and BaTiO<inf>3</inf> spheres were produced through a one-step hydrothermal process from amorphous TiO<inf>2</inf> spheres. The resulting samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and nitrogen sorption measurements. On the basis of the characterization results, we proposed a formation process of these porous spheres according to a mechanism analogous to the Kirkendall effect.

摘要:
In this paper, we report a simple method to synthesize V<inf>3</inf>O <inf>7</inf>·H<inf>2</inf>O nanobelts via hydrothermal treatment of commercial V<inf>2</inf>O<inf>5</inf> powder at relatively low temperatures. The synthetic process is free of any templates and reducing agents. The influences of reaction time and temperature on the morphologies of the resulting products have been investigated. The products were characterized by X-ray diffraction (XRD), X-ray photoelectron spectrometry (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and charge-discharge test. SEM and TEM analyses reveal that the products consist of a large quantity of belt-like nanostructures and the belts are 100-500 nm in width and several tens to several hundreds micrometers in length as well as about 20 nm in average thickness. The electrochemical test found that the nanobelts exhibited an initial high discharge specific capacity of 253.0 mAh/g in the potential range of 3.8-1.7 V and its stabilized capacity still remained 228.6 mAh/g after 50 cycles. All these results indicate that the resulting V<inf>3</inf>O <inf>7</inf>·H<inf>2</inf>O nanobelts are promising cathode materials in lithium-ion batteries. ©2005 Elsevier B.V. All rights reserved.
