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

IFRS 13 will help increase transparency when entities use models to measure fair value， particularly when users need more information about measurement uncertainty， such as when the market for an asset or a liability has become less active. IFRS 13 requires entities to disclose information about the valuation techniques and inputs used to measure fair value， as well as information about the uncertainty inherent in fair value measurements (which was of particular concern during the global fi nancial crisis). Some of those disclosures， including the fair value hierarchy， were already introduced in March 2009 through an amendment to IFRS 7 Financial Instruments: Disclosures. Those disclosures have been relocated to IFRS 13. The requirements in IFRS 13 also incorporate the guidance in a FASB Staff Position (FSP) issued in April 2009. 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

These detectors may alter the view of a signals appearance， depending on which is selected. Each detector can show a different picture on the same signal because of the way the detector functions. An important selection to our spectrum analyzer is the amount of digital snap shots to be taken. This will be the amount of digital snapshots that is taken in the allocated bandwidth before showing a picture. With this said， the more sampling that is put into the spectrum analyzer the slower it will seem to update， but more opportunity to capture ingress and other interference that can happen inside a cable plant. Dwell Wide- Dwell Wide takes the largest snapshot out of the amount taken， then the 7.5 MHz spectrum is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. Example: In Dwell Wide， with a 32 sampling rate set， this in turn means the 860 will dwell or sit on a portion of the spectrum defined above， take 32 snap shots， and then display the picture with the max amplitude before moving on to the next portion of bandwidth. Dwell Narrow- Dwell Narrow takes the largest snapshot out of the amount taken， then a 250 kHz spectrum slice is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. The difference between Dwell Narrow and Dwell Wide is that Dwell Narrow only peak holds across a 250 kHz slice， where as Dwell wide peak holds the entire 7.5 MHz. Example: In Dwell Narrow， with a 32 sampling rate set， this in turn means the 860 will go to the first 7.5 MHz of the spectrum it will look at a 250 kHz slice of the 7.5 MHz and take its 32 samples. These 32 samples will be done in a peak hold fashion， then display the sample that contains the largest signal. Averaging: This detector when selected looks at a 7.5 MHz portion of the spectrum. When it tunes to the first 7.5 MHz portion of the spectrum， it takes into account how much sampling is selected， then takes it’s digital snapshots on the entire 7.5 MHz， averages those pictures together， then shows the final averaged picture. This detector is used for looking at large amounts of bandwidth. Example: In Averaging， with a 32 sampling rate set， this in turn means the 860 will go to the first 7.5 MHz of the spectrum， take it’s 32 digital snap shots， average those together， and show the average of the 32 snapshots. 展開

請(qǐng)高手幫我翻譯一下這一段。。。: 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

In this paper， the degradation of an azo dye Orange G (OG) on nitrogen-doped TiO2 photocatalysts has been investigated under visible light and sunlight irradiation. Under visible light irradiation， the doped TiO2 nanocatalysts demonstrated higher activity than the commercial Dugussa P25 TiO2， allowing more ef?cient utilization of solar light， while under sunlight， P25 showed higher photocatalytic activity. According to the X-ray diffraction (XRD)， X-ray photoelectron spectroscopy (XPS) and UV–vis spectra analyses， it was found that both the nanosized anatase structure and the appearance of new absorption band in the visible region caused by nitrogen doping were responsible for the signi?cant enhancement of OG degradation under visible light. In addition， the photosensitized oxidation mechanism originated from OG itself was also considered contributing to the higher visible-light-induced degradation ef?ciency. The effect of the initial pH of the solution and the dosage of hydrogen peroxide under different light sources was also investigated. Under visible light and sunlight， the optimal solution pH was both 2.0， while the optimal dosage of H2O2 was 5.0 and 15.0 mmol/l， respectively. Azodyes， which are characterized by the presence of one or more azo bonds ( N N )， are among the most notorious widespread environmental pollutants associated with textile，cosmetic， food colorants， printing， and pharmaceutical indus-tries. Because of their non-degradability， toxicity， potential mutagenicity and carcinogenicity， wastewaters originating from these dyes production or application industries pose a major threat to the surrounding ecosystems and human beings’ health.[1–3].Environmental concerns and the need of meeting the strin-gent international standards for rejecting wastewaters has made the development of novel and cost-effective processes for the puri?cation of azo dyes ef?uents an issue of major technological importance. 展開
