摘要：
A novel optical biosensor assembled with gold colloidal nanoparticles on gold plate surface has been constructed via 1,4-dithiothreitol and L-cysteic acid for detection of bio-molecules like antigen, antibody protein and DNA plasmid, which exhibited distinct optical properties of localized surface plasmon resonance (LSPR). The prepared nano gold sol were characterized by using UV-Vis absorption spectroscopy, transmission electron microscopy (TEM), and cyclic voltammetry (CV), indicating that the Au colloidals were sphere-shaped and narrow-dispersed size distribution with a diameter of 24 ± 0.2 nm. It caused 2.80 nm of red shift in the peak wavelength (λmax) of LSPR spectrum for the nanosensor exposed to c-Myc (3C7) mouse monoclonal IgG and 3.36 nm of red shift to the corresponding antibody by the immuno-reaction subsequently. The LSPR nanobiosensor has been successfully applied to recognition of a DNA plasmid of pCMV-Myc Mammalian Expression Vector. ©2009 IEEE.

引言
闪点是可燃液体在空气中或液面附近产生蒸气,遇到明火或电火花时能被点燃的最低温度,它是衡量可燃液体火灾危险程度的重要物理量.通常蒸发速度越快,闪点越低,危险性越大,因此闪点在石油化工的理论研究、安全生产以及储存运输等方面有着极其重要的应用.

摘要：
In the title compound, C24H39NO2· H2O, the A and C rings of the pregnolene derivative sterol adopt chair conformations, with the B ring in a flattened chair conformation and the five-membered ring in an envelope conformation twisted about the C/D ring junction. The N-tert-butyl-carboxamide substituent is equatorial. The 3β-hydr-oxy H atom and one H atom of the water mol-ecule are disordered over two positions with equal occupancies. In the crystal structure, O - H⋯O hydrogen bonds between the 3β-hydr-oxy groups of neighbouring mol-ecules form dimers in the bc plane and these dimers are stacked along the a axis by additional O - H⋯O hydrogen bonds involving the water mol-ecules. The steric effect of the bulky tert-butyl substituent in the carboxamide chain precludes hydrogen-bond formation by the N - H group. © 2009.

摘要：
In the title compound, C11H11N2O 2S+·ClO4 -, the dihedral angle between the benzene and pyridinium rings is 87.33 (10)°. An intra-molecular N - H⋯O inter-action, with an S=O-bonded O atom as receptor, occurs in the cation. In the crystal structure, ion pairs occur, being linked by strong N - H⋯O hydrogen bonds. The perchlorate anion plays a further role in the mol-ecular packing by accepting several weak C - H⋯O inter-actions.

摘要：
The mol-ecule of the title compound [systematic name: 2-(4-tert-butyl-benz- yl)isoindoline-1,3-dione], C19H19NO2, is V-shaped with a dihedral angle of 74.15 (7)° between the mean planes of the phthalimide unit and the benzene ring. The methyl groups of the tert-butyl substituent are disordered over two sets of positions, with an occupancy ratio of 0.700 (4):0.300 (4). In the crystal, inter-molecular C - H⋯O hydrogen bonds link adjacent mol-ecules into centrosymmetric dimers. An additional weak C - H⋯O contact, together with weak C - H⋯π and π-π inter-actions [centroid-centroid distance = 3.961 (2) Å] generate a three-dimensional network. © 2009 Li et al.

摘要：
Bicyclic [2,2,1] heptane di-carboxylate (commercial product name: HPN-68) is a novel nucleating agent with high nucleation efficiency for α-iPP. In this article, differential scanning calorimetry (DSC) was adopted to investigate the isothermal crystallization kinetics of isotactic polypropylene (iPP) nucleated with HPN-68. The Avrami equation well described the isothermal crystallization kinetics of iPP nucleated with HPN-68. The results showed that addition of HPN-68 could shorten half crystallization time (t<inf>1/2</inf>) and increase the crystallization rate of iPP significantly. The Avrami exponents of both virgin iPP and iPP nucleated with HPN-68 were close to 3.0, which indicated that the addition of nucleating agent HPN-68 didn't change the crystallization growth patterns of iPP under isothermal conditions and the crystal growth was heterogeneously nucleated three-dimensional spherulitic growth. In addition, incorporation of nucleating agent HPN-68 obviously decreased the crystallization activation energy ΔE of iPP, from 368 kJ/mol for virgin iPP to 306 kJ/mol.

摘要：
A single-chamber, membrane-less and floating-cathode microbial fuel cells (MFC) was successfully started up using surplus sludge as fuel without adding carbohydrate after 20 days. The electricity generation of the MFC was investigated. The results showed that the obtained maximum voltage was 440.7 mV when external resistance was 1,000 Omega. There were four phases (rapid fall phase, stationary phase, fall phase and stationary phase of low voltage) in the periodic time of MFC, and the output voltage range of 150-300 mV lasted for 107 hours during stationary phase. In addition, the obtained maximum power density was 220.7 mW m(-2) and internal resistance was 368.13 Omega in the MFC. Consequently, surplus sludge could be used to generate electricity in MFC, which could provide a novel process for sludge recycling.

摘要：
Effects of a novel nucleating agent bicyclic [2,2,1] heptane di-carboxylate (HPN-68) on the properties, crystallization, and melting behavior of isotactic polypropylene (iPP) were studied. The results showed that HPN-68 is a typical nucleating agent for α-iPP and it has high nucleation efficiency. Addition of a small amount of HPN-68 to iPP can obviously increase crystallization peak temperature and mechanical properties of iPP. When the concentration of HPN-68 is 0.2 wt.%, the crystallization peak temperature can be increased by about 15°C, and the tensile strength and flexural modulus of iPP can be increased by 12.74% and 18.24%, respectively.

Soy protein aggregate;Dextran;Ionic strength, Phase separation;Microstructure
摘要：
The effects of ionic strength on heat-induced aggregation of soy protein and phase separation of different soy protein aggregates with dextran were investigated. The increase of ionic strength accelerated protein aggregation as shown by an increase in turbidity, aggregate fraction and particle size of salt-induced aggregates (SA). Adding salt (NaCl) to the aggregates formed at the ionic strength of zero (non-salt aggregates, non-SA), the increase of aggregate size was also found. Zeta potential results evidenced the charge screening effects of NaCl. The results of phase diagrams indicated that the compatibility of mixtures at higher ionic strength was lower than those at lower ionic strength, and SA was more incompatible with dextran than non-SA. The effects of the increase of aggregate size on the phase separation outweighed the ionic strength, which indicated that the depletion interaction also played an important role in the phase separation of soy protein aggregates and dextran. CLSM (Confocal Laser Scanning Microscopy) and rheological observations provided additional information of the microstructures of the mixtures. © 2008 Elsevier Ltd. All rights reserved.

摘要：
研究了在NH4Ac缓冲溶液中,钇(Ⅲ)和水杨基荧光酮(SF)的络合显色反应.结果表明,在pH 7.0 NH4Ac的缓冲溶液和溴化十六烷基三甲基铵(CTMAB)存在下,有色溶液的最大吸收波长为560 nm,表观摩尔吸光系数为1.6×105,钇(Ⅲ)质量浓度在0～0.35 mg/L范围内符合比尔定律,加标回收率在98.8%～105.2%之间,RSD(n=·6)为2.8%～5.2%.本法可用于测定煤矸石中微量钇.

摘要：
Nanocrystalline La3+-doped TiO2 of 20-30 nm in size was prepared by a sol-gel technique. The photocatalytic activities of the samples were evaluated by the degradation of harmful acid orange 7(AO7) azo-dye in aqueous solution. The effects of La3+ ion implantation on the photocatalytic activity of TiO2 were also discussed. The results show that the La3+content plays an essential role in affecting the photocatalytic activity of the La3+-doped TiO2 and the optimum content of La3+-doped is 1.0 wt.%. The photocatalytic activity of the samples with La3+-doped TiO2 is higher than that of pure TiO2 in the treatment of AO7 wastewater. The photodegradation effect of AO7 effluent is the best by means of La3+-doped TiO2 with 1.0% La3+.
