摘要：
以Gd~(3+)和Eu~(3+)为掺杂剂,分别采用溶胶 - 凝胶法和水热法制备了稀土共掺杂纳米TiO_2/MWCNT(multi-walled carbon nanotube)复合光催化剂,用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、光致荧光光谱仪(PL)对光催化剂进行表征,以甲基橙为目标降解物对催化剂进行活性评价.结果表明:水热法制得的复合光催化剂样品中,二氧化钛颗粒基本均匀分布在碳纳米管上,同时,其光催化活性也比溶胶 - 凝胶法制得的样品高;Gd~(3+)和Eu~(2+)共掺杂能有效提高其光催化活性,当Gd~(3+)和Eu~(2+)掺杂量为分别为0.1%和1.0%时,TiO_2/MWCNT复合光催化剂具有较高的光催化活性.

摘要：
A method for measuring the electrochemical Peltier heat (EPH) of a single electrode reaction has been developed and an absolute scale is suggested to obtain EPH of the standard hydrogen electrode. The scale is based on φ{symbol}<inf>0</inf><sup>*</sup> = 0 and ΔS<inf>0</inf><sup>*</sup> = 0 for any electrode reaction at zero Kelvin, in accord with the third law of thermodynamics. The relationships between entropy, enthalpy and free energy changes on this scale and on the conventional scale are derived. Calorimetric experiments were made on the Fe(CN)<inf>6</inf><sup>3-</sup>/Fe(CN)<inf>6</inf><sup>4-</sup> system at five different concentrations at 298.15 K, and EPH for the standard hydrogen electrode reaction is obtained. EPHs and the entropy change on the absolute scale for the studied redox are linearly related to concentration of electrolyte. The reversible electric work is almost concentration independent in the range of concentration studied. ©2008 Elsevier B.V. All rights reserved.

摘要：
The aim of this work was the synthesis of a new family of lactosylated piperazinly porphyrins in which the galactoside piperazine moieties are linked to the tetra- and monophenyl ring by an amide bond. Two compounds were designed, synthesized, and characterized by 1H-nuclear magnetic resonance (1H-NMR), ultraviolet (UV)-visible, and matrix-assisted laser desorption/ionization (MALDI) mass spectra. The biological activity on cancer cells and the pharmacokinetics have also been evaluated, showing a very high liver-to-skin ratio and short retention time in tissues. It is suggested that such novel lactosylated piperazinyl porphyrins, as potential hepatocyte-selective targeting drugs, thus show promising activity in photodynamic therapy. © Birkhäuser Boston 2007.

摘要：
A water-soluble lactosylated piperazinyl porphyrin, 5- mono[4-(4'-lactobionylaminopiperazinyl)- phenyl]-10,15,20- triphenyl-porphyrin (MLPP), was synthesized basing on the porphyrin's special affinity for cancer cells and the antitumor activity of piperazine compounds. Its structure was characterized by UV-Vis spectra, elemental analysis and 1H NMR. A model for the interaction between MLPP and DNA was built, and the binding mechanism between MLPP and cell molecules was investigated by UV-Vis spectra and fluorescence spectrum.

摘要：
用4×4阵列丝束电极模拟研究了混凝土中钢筋的腐蚀,将钢筋混凝土做不同的涂层处理:空白、铁丝表面涂抹树脂、混凝土表面涂抹树脂.通过测量铁丝的自腐蚀电位,研究不同涂层方式对混凝土防腐方面的影响.实验结果表明:只在混凝土表面涂抹树脂是最好的保护方式,它可以使钢筋的腐蚀电位一直处于钝化范围内,从而保证了钝化膜的完整性.这一结果对防止沿海地区和冰雪融化剂的氯离子对混凝土的破坏作用有意义,同时可应用于有杂散电流作用的混凝土结构物的防腐蚀.

讨论了超细粉碎马铃薯淀粉颗粒粒径对淀粉糊黏度及弹性的影响.分析结果表明:机械研磨作用能够明显地破坏淀粉分子的结晶结构,导致其结晶度降低,而无序化程度增加.淀粉糊的静态黏度随样品颗粒粒径的增大而增大,随球磨时间的增长而减小,静态弹性也同样随样品颗粒粒径的增大而增大,随球磨时间的增长而减小;当颗粒粒径为10～30μm,淀粉糊黏度呈现最小值,但是淀粉的弹性不变.

摘要：
合成了一种新型辣根过氧化物酶（HRP）荧光底物-4-羟基苯乙基吡啶（pHSP），并首次将它运用于酶联荧光免疫传感体系。对pHSP化学性质的研究证实，pHSP在空气中较稳定，对HRP，H_2O_2的荧光响应性能优于传统HRP荧光底物，如对羟苯乙酸、Amplex Red和佳味醇等，在pH5．8的Britton-Robinson缓冲溶液中，pHSP本身只有极弱的荧光，在HRP-IgG催化下可被H2O2氧化成二聚体产物，该二聚体在300nm的激发光下能发射波长为437nm的强荧光，并且反应体系的荧光增加与HRP量在一定浓度范围内成线性相关。根据此原理，建立了兔布氏杆菌抗体的酶联荧光传感分析新方法，运用制备的传感装置测定兔布氏杆菌抗体的线性范围为6．3×10~(-11)～1×10~(-8)mol·L~(-1)，抗体检出限为6．3×10~(-11)mol·L~(-1)，相对标准偏差为4．1％（n=11），pHSP的二聚体产物水溶性很低，利用设计的装置较好地解决了传统测定溶液体系方法灵敏度不高的问题。

摘要：
We have proposed an electrochemical detection method for DNA molecules based on an extended gate field effect transistor (EGFET) sensing chip which consists of one gold plate for molecule recognition and FET part for signal transduction. DNA Probes were immobilized on the gold plate by forming mixed monolayers of thiolated single-stranded oligonucleotide (HS-ssDNA) and alkanethiols, like 6-hydroxy-1-hexanethiol (6-HHT). Electrode reaction corresponding to the reductive desorption of the adsorbed monolayers in strong alkali solution was presented for quantification of surface density of DNA by using fast cyclic voltammetry (FCV). The passivation effects of surface modification with different functional groups on the potential behavior of the gold electrode were also examined. It was feasible to use EGFET chip for detection of DNA hybridization reaction, that the hybridization efficient was estimated to be about 40%.

摘要：
Purpose - The purpose of this paper is to consider the use and application of the "grey system" modelling methodology for the prediction and characterisation of inert anodes used in the aluminium electrolysis industry. Design/methodology/approach - Cermet was very interesting potential material for developing inert anodes, which was composed of ceramic phase (NiFe <inf>2</inf>O<inf>4</inf>) and metal/alloy phase (nickel-iron-copper). Findings - Differential thermal analysis showed that newly fabricated cermet had good performance. The calcination temperature was very important for evaluating material properties, so was obtained in order to build the forecast grey model. Originality/value - Through calculation the GM(1,1) model was proved to be accurate in predicting technical parameters, and able to pinpoint precisely the properties of cermet materials. ©Emerald Group Publishing Limited.

In the title compound, C11H10N3O4S+·C2F3O2 -, the benzene ring makes an angle of 87.3 (2)°with the pyridinium ring. The nitro group is essentially coplanar with the benzene ring. The F atoms of the CF3 group are disordered over two positions with almost equal occupancy [0.531 (12)/0.469 (12)]. The crystal structure is stabilized by N - H⋯O and C - H⋯O hydrogen bonds.
