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

LabVIEWTM(LaboratoryVirtualInstrumentEngineeringWorkbench)isapowerfulinstrumentationandanalysisprogramminglanguageforPCsrunningMicrosoftWindows,SunSPARCstations,AppleMaci... LabVIEWTM (Laboratory Virtual Instrument Engineering Workbench) is a powerful instrumentation and analysis programming language for PCs running Microsoft Windows, Sun SPARCstations, Apple Macintosh computers, Concurrent PowerMax, and HP-UX workstations. LabVIEW departs from the sequential nature of traditional programming languages and features a graphical programming environment and all the tools needed for data acquisition, analysis, and presentation. With this graphical programming language, called “G,” you can program in a block diagram notation, the natural design notation of scientists and engineers. After you create a block diagram program, LabVIEW compiles it into machine code. LabVIEW integrates data acquisition, analysis, and presentation in one system. For acquiring data and controlling instruments, LabVIEW supports RS-232/422, IEEE 488 (GPIB), and VXI, including Virtual Instrument Software Architecture (VISA) functions, as well as plug-in data acquisition (DAQ) boards. An instrument library with drivers for hundreds of instruments simplifies instrument control applications. For analyzing data, the extensive Analysis library contains functions for signal generation, signal processing, filters, windows, statistics, regression, linear algebra, and array arithmetic. Because LabVIEW is graphical in nature, it is inherently a data presentation package. LabVIEW can generate charts, graphs, and customized, user-defined graphics. 盡量翻的好一點,謝謝 能不能對GOOGLE自動翻譯過的稍加修改下 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.

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

A new kind of TiO2 nanotube array/Ni(OH)2 (TiO2/Ni(OH)2) composite electrode with the storage ability of light energy was prepared by the deposition of Ni(OH)2 on the TiO2 nanotube array, which was synthesized by anodizing Ti foils in an HF aqueous solution. SEM and XRD results showed that Ni(OH)2 particles were well distributed on high density, well-ordered and uniform TiO2 nanotube arrays. The photoelectrochemical properties of the TiO2/Ni(OH)2 electrode were investigated in NaHCO3/NaOH buffer solution (pH 10) by means of UV–vis absorption spectra, cyclic voltammogram (CV) and photocurrent measurements. It was found that the TiO2/Ni(OH)2 electrode was highly sensitive to light and exhibited excellent photoelectrochromic properties. Upon UV irradiation, the photogenerated holes by TiO2 nanotube arrays can oxidize Ni(OH)2 to NiOOH, and thus the TiO2/Ni(OH)2 electrode can be photo-charged by light。1. Introduction Among many visible light photocatalysts, TiO2nanostructures have attracted much attention due to high photocatalytic activ-ity, nontoxicity, chemical stability and huge potential applications [1–6]. The TiO2 nanotube array is one of most attention-getting TiO2nanostructures because of large surface area and outstanding charge transport properties. TiO2nanotube arrays can be utilized in dye-sensitized solar cells[7–9], photocatalysis and hydrogen gas sensing [10]. So far, a variety of methods have been attempted to prepare TiO2 nanotube arrays, such as hydrothermal synthe-sis[11], Langmuir–Blodgett technique [12], solution casting [13] and anodization technique[10,14], etc. Among these methods, the anodization technique has many advantages of low cost, low tem-perature and easy to be scaled up to large-area preparation. Recently, anewkindof photo-functional systemwith theenergy storage ability has been developed by coupling TiO2 photosen-sitive electrode with energy storage materials. In Takahashi and Tatsuma’swork[15],aTiO2/Ni(OH)2bilayer thinfilmwas suggested for the oxidative energy storage. In this case, a redox-activep-type semiconductor Ni(OH)2is coupled withn-type TiO2photocatalyst to formap–njunction,WhenTiO2is illuminatedby light, holesgen-erated at the junction are separated from excited electrons, trans-ported into the bulk of Ni(OH)2and oxidized Ni(OH)2to NiOOH. Therefore, the oxidative energy storage system was constructed 展開

Since its advent in the early 1970s the logic analyser has become arguably the most important single piece of test equipment in the digital designer’s armoury. It is now a far more versatile instrument than its early predecessors, still offering a complete solution to today’s ever more complex digital design and measurement challenges. As with most modern test equipment, the ongoing development of logic analysers has been fuelled by continual improvements in microprocessor technology, allowing cost-effective implementation of advanced measurement techniques. This continual development has been driven, to a great extent, by the need to be able to debug complex microprocessor-based or highspeed state machine designs. As the inclusion of microprocessor or VLSl components into circuit design becomes more and more routine, the instrument manufacturer must maintain the logic analyser as a user-friendly, relatively-low-cost solution to modern digital design and test problems. In addition, however, as these components increase in both complexity and performance, the instrument manufacturer must be able to support state-of-the-art measurement techniques, while still offering the digital design engineer the same depth of general-purpose circuit analysis.Clearly, as design complexity increases, an increasing volume of measurement data must be represented and manipulated in such a way that it can be quickly and easily interpreted by the engineer. The basic logic analyser provides a means of monitoring software execution, digital hardware operation and, more importantly to many, the interaction between the two. Being the only instrument that can comprehensively bridge this notional divide between hardware and software, the logic analyser is often given the role of arbitrator in the search for that elusive system bug. 展開

4.VIRTUALINSTRUMENTAfoundationofthecontrolsystemdesignistheconceptofvirtualinstruments.Intraditionalobservatorysystemdesign,instrumentsaretypicallyconsideredentitieswhose... 4. VIRTUAL INSTRUMENT A foundation of the control system design is the concept of virtual instruments. In traditional observatory system design, instruments are typically considered entities whose design and components are fixed well in advance of actual use of the instrument. The approach works quite well when the role of the instrument is well understood with respect to the experiments it is to be used for. It also fits well with a system design where the instruments must be mounted on the telescope (e.g. mounting at the Cassegrain focus), or exposed to the external environment - since the instrument is static, it can be more easily enclosed. However, this approach has some drawbacks in a laboratory style environment such as that provided by the ATST multiple-bench coude lab. In particular, providing the flexibility to explore new experiments results in a significant effort to adapt existing instruments to meet the requirements of the new experiment. The Virtual Instrument Model has been developed to address this issue, by abstracting the concept of an instrument from the specifics of the components used within that instrument. This allows the configuration of an instrument to be quickly adapted to meet the changes required by different experiments or changes to the laboratory environment. It should be noted that the virtual instrument is not a revolutionary concept but rather is the formalization of ideas often used in laboratory style experimentation. In the virtual instrument model, it is the experiment that drives the virtual instrument's 'design'. 4.1. EXPERIMENTS AND INSTRUMENTS Experiments are the heart of ATST operations and the control system is designed with this in mind. A laboratory style environment provides flexible support to carry out Experiments that are likely not understood or defined at the time the laboratory itself is designed. An Experiment undertaken at the ATST requires a Virtual Instrument. 不要機器翻譯的 要人工的 謝謝大家 展開

Its cone and plate geometry provides the precision necessary for development of complete rheological data. Principle of Operation The Wells-Brookfield Cone/Plate Viscometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system, which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone, senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate. The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the fluid. The amount of torque is indicated either on a dial or digital display, depending on model. This reading is easily converted to absolute centipoise units (mPa.s) from pre-calculated range charts. Alternatively, viscosity can be calculated from the known geometric constants of the cone, the rate of rotation, and the stress related torque. See Range Tables The correct relative position of cone and plate is obtained by following a simple mechanical procedure without the need for external gauges or supplementary instrumentation. The stationary plate forms the bottom of a sample cup which can be removed, filled with .5 ml to 2.0 ml of sample fluid (depending on cone in use), and remounted without disturbing the calibration. The sample cup is jacketed and has tube fittings for connection to a constant temperature circulating bath. The system is accurate to within ?.0% of the working range. Reproducibility is to within ?.2%. Working temperature range is from 0oC to 100oC. 展開
