- LabVIEWisapowerfulandcomplexprogrammingenvironment.LabVIEWisshortforLaboratoryVirtualInstrumentEngineeringWorkbench.Itisapowerfulandflexibleinstrumentationandanalysissoft... LabVIEW is a powerful and complex programming environment. LabVIEW is short for Laboratory Virtual Instrument Engineering Workbench. It is a powerful and flexible instrumentation and analysis software development application created by the folks at National Instruments—a company that creates hardware and software products that leverage computer technology to help engineers and scientists take measurements， control processes， and analyze and storem data. National Instruments was founded over twenty-five years ago in Austin， Texas by James Truchard (known as Dr. T)， Jeffrey Kodosky， and William Nowlin. At the time， all three men were working on sonar applications for the U.S. Navy at the Applied Research Laboratories at The University of Texas at Austin. Searching for a way to connect test equipment to DEC PDP-11 computers， Dr. T decided to develop an interface bus. He recruited Jeff and Bill to join him in his endeavor， and together they successfully developed LabVIEW and the notion of a “virtual instrument.” In the process they managed to infuse their new company—National Instruments—with an entrepreneurial spirit that still pervades the company today. Engineers and scientists in research， development， production， test， and service industries as diverse as automotive， semiconductor， aerospace， electronics， chemical， telecommunications， and pharmaceutical have used and continue touse LabVIEW to support their work. LabVIEW is a major player in the area of testing and measurements， industrial automation， and data analysis. For example， scientists at NASA’s Jet Propulsion Laboratory used LabVIEW to analyze and display Mars Pathfinder Sojourner rover engineering data， including the position and temperature of the rover， how much power remained in the rover’s battery， and generally to monitor Sojourner’s overall health. LabVIEW provides an extensive library of virtual instruments and functions to help you in your programming. It includes conventional program debugging tools with which you can set breakpoints， single-step through the program， and animate the execution so you can observe the flow of data. 畢業(yè)設計急用，望高手幫忙翻譯一下 展開

Bimetallic dendrimer-encapsulated nanoparticles(DENs)are important materials，because they have demonstrated improvement in performance compared to the monometallic DENs in many systems when they are used as catalysts.This tutorial review focuses on the recent research advances in bimetallic DENs with respect to their synthesis，characterization，and applications as catalysts.Bimetallic DENs can be made mainly via three routes:co-complexation，sequential loading，and partial displacement.The research in bimetallic DENs has been significantly promoted by the advancement of characterization instruments.The performances of bimetallic DENs as homogeneous and heterogeneous catalysts in organic synthesis have been compared with both monometallic DENs and their physical mixtures.It is concluded that the synergistic electronic effect in bimetallic nanoparticles enhances their catalytic activities. 能翻譯多少都可以的 展開

- Carbonnanomaterialsarenovelmanufacturedmaterials，havingwidespreadpotentialapplications.Adsorptionofhydrophobicorganiccompounds(HOCs)bycarbonnanomaterialsmayenhancetheirto... Carbon nanomaterials are novel manufactured materials， having widespread potential applications. Adsorption of hydrophobic organic compounds (HOCs) by carbon nanomaterials may enhance their toxicity and affect the fate， transformation， and transport of HOCs in the environment. In this research， adsorption of naphthalene， phenanthrene， and pyrene onto six carbon nanomaterials， including fullerenes， single-walled carbon nanotubes ， and multiwalled carbon nanotubes was investigated， which is the first systematic study on polycyclic aromatic hydrocarbons (PAHs) sorption by various carbon nanomaterials. All adsorption isotherms were nonlinear and were fitted well by the Polanyi-Manes model (PMM). Through both isotherm modeling and constructing “characteristic curve”， Polanyi theory was useful to describe the adsorption process of PAHs by the carbon nanomaterials. The three fitted parameters (Q0， a， and b) of PMM depended on both PAH properties and the nature of carbon nanomaterials. For different PAHs， adsorption seems to relate with their molecular size， i.e.， the larger the molecular size， the lower the adsorbed volume capacity (Q0)， but higher a and b values. For different carbon nanomaterials， adsorption seems to relate with their surface area， micropore volume， and the volume ratios of mesopore to micropore. Quantitative relationships between these sorbent properties and the estimated parameters of PMM were obtained. These relationships may represent a first fundamental step toward establishing empirical equations for quantitative prediction of PAH adsorption by carbon nanomaterials and possibly other forms of carbonaceous (geo-) sorbents， and for evaluating their environmental impact. In addition， high adsorption capacity of PAHs by carbon nanotubes may add to their high environmental risks once released to the environment， and result in potential alteration of PAHs fate and bioavailability in the environment. 展開

Physical and physicochemical characterization The particle size distribution of the Ch-zeolite was determined using a laser diffraction equipment (CILASk 1064) and standard wet sieving (Mesh Tylerk series). Scanning electron microscopy (SEM-PHILIPSk XL20) was used for photomicrographs as well as to analyse the Ch-zeolite composition (Energy Dispersion X-ray， EDX). The sample was initially placed in a vacuum chamber for coating with a thin layer (few nanometers) of gold (Au). The specific surface area of the material was measured by the methylene blue technique and by nitrogen gas adsorption methods， with the latter also providing information about particle porosity. In the methylene blue adsorption method， aqueous solutions (50 ml) of methylene blue (100 mg l 1) were agitated using an orbital shaker (Marconik) for an hour at room temperature in the presence of different quantities of the Ch-zeolite (0.05–0.3 g). The suspensions were then allowed to settle for 23 h and the resulting supernatants were centrifuged at 5000 rpm before the analysis of the residual methylene blue concentration. Results obtained correspond to averaged values of three different experiments. The specific surface area was evaluated by the Langmuir model， assuming the formation， at high concentrations， of a dye monolayer and 1.08 nm2 molecule 1， for the cross-sectional area (Van den Hul and Lyklema， 1968). The Ch-zeolite specific surface area was evaluated by the nitrogen gas adsorption method， using automated equipment (Autosorb 1-Quantachrome Instrumentsk)， employing multipoint BET isotherm adsorption data fitting. Also from these data， the porosity of the material was evaluated through parameters such as volume of total pores (d < 206 nm)， surface area and volume of micropores (d < 2 nm; Micropore Analysis Method). Zeta potential measurements for the natural and ammonia loaded zeolite， as a function of medium pH， were determined using a Zeta Plusk equipment (Brookhaven Instruments). Suspensions (0.01% v/v) of the Ch-zeolite， previously sieved below 37 Am (400 Mesh Tylerk)， in a 10 3 mol l 1 solution of KNO3 were used and the medium pH was controlled with the addition of HNO3 (pH< 7) and KOH (pH>7)， separately. For the Ch-zeolite saturated with ammonia， suspensions of the material were prepared by the same procedure， except that the sample was loaded with 100 mg NH3–N l 1 of ammonia. 展開

Microbial mapping The intensity of resonance Raman spectra of Cyt c allows for integration times below one second. Microbial mapping of an area of 50×50 μm2 with a resolution of 500 nm/pixel (10，000 single spectra) can be performed in less than 3 h. A further reduction of the measuring duration by a factor of 10 can be achieved by utilisation of an EMCCD camera (Coates et al.， 2004). Microbial mapping was done on granules from two different sequencing batch reactors (SBR) (Gaul et al.， 2006). The SBRs are used to analyse control parameters for the anaerobic ammonium oxidation. Fig. 7 shows two different microbial colonies in the same granulum. A graphical analysis of the spectroscopic data at 750 cm-1 (dominant resonant Raman band of Cyt c) and 2900 cm-1 (CH stretching mode) differentiated the two colonies. One colony shows stronger Raman signals at 750 cm-1 (blue frame). Whereas the other microorganisms have more amount of methyl or methylene groups (yellow frame). After the graphical analysis above， an average spectrum was constructed for each colony. The resulting averaged spectra were transferred to our Raman database of wastewater bacteria created by OPUS. The software recognized the microorganisms Fig. 5. Time series of N. eutropha Nm 57 which is captured by optical tweezers. Time difference between spectra: 1 s; Laser power: 9 mW.
