    ABSTRACT: In this work, Raman spectroscopic analysis was applied to determine the structures and cage occupancies of the hydrates that formed from the system of flue gas (simulated by carbon dioxide–nitrogen–sulfur dioxide)–sulfur dioxide aqueous solution, and from the system of flue gas–sulfur dioxide containing tetra-n-butyl ammonium bromide (TBAB) aqueous solutions (sulfur dioxide mass concentration 0, 1.0, and 7.0 wt%). Comprehensive TBAB (solid, aqueous, and hydrate) Raman spectra were also obtained. The results reveal that when TBAB is used as promoter, both sulfur dioxide and carbon dioxide are encaged in the hydrate from systems of flue gas-TBAB solution with low sulfur dioxide concentration (0, 1.0 wt%), whereas in the hydrate from the system of flue gas-sulfur dioxide highly concentrated (7.0 wt%) TBAB solution, sulfur dioxide will be the sole gas guest encaged in the semi-clathrate hydrate. This suggests the sulfur dioxide concentration significantly influences the hydrate cage occupancies and separation selectivity of the hydrate-based technology. A two-stage hydrate-based flue gas purification process is proposed: one aims at desulfurization when sulfur dioxide concentrates to a relatively high level with the solutions recycling and in the other we can remove the sulfur dioxide and carbon dioxide simultaneously.

    ABSTRACT: The characteristic changes in UV-visible and Raman spectra of lithocholic acid on E-2-Butenal for antiglioma are the maximum absorption peak of E-2-Butenal from 302 to 319 nm, the decreases of Raman signal of 1688 cm−1 and 1641 cm−1 in E-2-Butenal by lithocholic acid with the phenomenon of 1688 cm−1 splitting, and the disappearance of the band at 932 cm−1, which clearly displays the change of wagging in methyl. In the presence of mitochondrial protein deriving from glioma, the above mentioned effects of lithocholic acid on E-2-Butenal are more significant by Raman spectra detections. The molecular targets of lithocholic acid on E-2-Butenal are carbonyl group, conjugated double bonds, and methyl, respectively. The study concludes that the interaction between lithocholic acid and E-2-Butenal decreases the carbonyl group bond strength in E-2-Butenal and then changes the structure and function of E-2-Butenal. The internal cause of the interaction between lithocholic acid and E-2-Butenal leading to the change of the carbonyl group bond strength is the electronic delocalization near the carbonyl group bond in E-2-Butenal. Since E-2-Butenal derives from glioma in the process of lipid peroxidation of mitochondria, our investigation significantly contributes to understanding the mechanism of action of lithocholic acid as a potential antiglioma drug.

    ABSTRACT: The Raman studies of lead zirconate titanate with varied grain size from 27.5 nm to 983 nm were performed under pressure up to 32 GPa to elucidate the scenario of phase transition pressures of lead zirconate titanate, which lies in the morphotropic phase boundary. The coexistence of ferroelectric rhombohedral and tetragonal phases at ambient condition changed to the coexistence of tetragonal and cubic phases at intermediate pressure and finally, transited to paraelectric cubic phase at elevated pressure. The pressure evolution of Raman spectra results indicated that the phase transition pressure increased with the reduction of the particle size.

    ABSTRACT: Urine contains a variety of compounds including a number of natural fluorophores. Fluorescence spectroscopy has proven to be a useful tool in analytical science. Fluorescence detection has three major advantages over other light-based investigation methods: high sensitivity, speed, and safety. Our work presents the newest approach to analysis of dog urine. Fluorescent fingerprint can very quickly reveal differences between complicated mixtures without adding any reagents. We describe autofluorescence characteristics of the urine of healthy dogs and of those with various disorders using fluorescent fingerprint. Fluorescent analysis has given good results to distinguish between pathological urine and the healthy standard in dogs. Our results suggest that this method can be used to characterize fluorescent properties of canine urine and to reveal some pathological changes in dogs.

    ABSTRACT: The structural and morphological features influencing the glass transition temperature of epoxy/silica nanohybrid and nanocomposite materials containing 25–30 phr of nanoscale silica phases are discussed in this letter to answer the questions related to the processing–structure–property relationships. X-ray photoelectron spectroscopy and atomic force microscopy are used to study the surface chemical structure and morphology of epoxy/silica nanohybrids and nanocomposites. Nanohybrids are synthesized via in situ sol-gel process, while the respective nanocomposites are prepared by mechanical blending of preformed silica nanoparticles into epoxy resin. Differential scanning calorimetry is used to determine glass transition temperature of different materials. The surface analytical characterizations reveal that in situ sol-gel process is more suitable for producing organic–inorganic hybrid materials with superior glass transition temperature owing to the achievement of stronger interfacial compatibility and greater crosslink density. A number of other factors affecting glass transition temperature are explored and discussed with reference to surface chemistry, microstructure, and morphology of epoxy/silica nanohybrids and nanocomposites, respectively.

    ABSTRACT: Water-soluble cadmium selenide/cadmium sulfide/zinc sulfide core/shell/shell quantum dots were synthesized in aqueous solution using trisodium citrate as modifier. The crystal structure, morphology, component, and spectral properties of cadmium selenide/cadmium sulfide/zinc sulfide core/shell/shell quantum dots were characterized by X-ray power diffraction, transmission electron microscope, energy dispersive X-ray analysis, infrared spectrum, ultraviolet–visible absorption spectrum, and fluorescence spectrum. The results show that the spherical citrate-modified cadmium selenide/cadmium sulfide/zinc sulfide core/shell/shell quantum dots with diameter around 3.6 nm belong to the cubic zinc blende structure. The citrate-modified cadmium selenide/cadmium sulfide/zinc sulfide core/shell/shell quantum dots show a narrow, symmetric, and strong fluorescence emission spectrum band with narrow full width at half maximum of 53 nm, and the fluorescence quantum yield can reach up to 37.3%. The high-quality citrate-modified cadmium selenide/cadmium sulfide/zinc sulfide core/shell/shell quantum dots with good fluorescence properties have potential for application in biological fluorescence analysis.

    ABSTRACT: This study describes a measuring system for mass spectrometry, consisting of a glow discharge ionization source for soft plasma ionization and a time-of-flight mass spectrometer, to detect toxic volatile organic compounds rapidly and easily. It is the most important to determine how the complicated fragmentation of such compounds can be suppressed to occur so as to recognize the mass spectra of the volatile organic compounds as their fingerprints. The novelty of this work is that the optimal discharge condition for the soft plasma ionization–time-of-flight mass spectrometer system could be selected, so that the parent mass peak of analyte molecules could be observed both with high sensitivity and with little or no fragmentation of them. Use of air gas at a pressure of 1000 Pa provided the most favorable result for these criteria, whereas, in a previous report, the soft plasma ionization source operating with argon at a pressure of 346 Pa had yielded additional mass peaks of the fragmented species. The reason for this would be explained by the fact that energetic electrons in the plasma, which principally cause the fragmentation of the volatile organic compounds, have lower number density at higher gas pressures, through de-accelerated collisions with the plasma gas.

    ABSTRACT: A fixed time point on the curve of the absorbance variation with time determined in the hydroxyl polyaluminum solution by 7-iodine-8-hydroxyquinoline-5-sulfonic acid-timed spectrometry is usually used to quantify the mononuclear aluminum species in the hydroxyl polyaluminum solution. The right choice of the determining time of mononuclear Al must be established on the basis of the sufficient reaction between chromogenic reagent and the hydroxyl polyaluminum solution. But this question has never been noted, which resulted in the confusion of application and research of this assay. In this work, the effect of variation of the determining time on the accurate determination of mononuclear Al in the hydroxyl polyaluminum solution was first studied. The experimental results showed that 60 s was the best under the appropriate dosage of 7-iodine-8-hydroxyquinoline-5-sulfonic acid. The reasonableness of 60 s was further verified by 27Al nuclear magnetic resonance spectrometer and the absorbance–time curve obtained from the pure mononuclear Al solution with pH 60, and Keywords: Ferron-timed spectrophotometry; determining time of mononuclear Al; mononuclear aluminum Document Type: Research Article DOI: http://dx.doi.org/10.1080/00387010.2014.883543 Affiliations: 1: Department of Biology and Food, Zhejiang Pharmaceutical College, Ningbo, China 2: Department of Materials Engineering, Hubei University of Automotive Technology, Shiyan, China 3: Department of Environmental Engineering, College of Environmental Sciences and Engineering, Peking University, Beijing, China Publication date: May 28, 2015 $(document).ready(function() { var shortdescription = $(".originaldescription").text().replace(/\\&/g, '&').replace(/\\, '<').replace(/\\>/g, '>').replace(/\\t/g, ' ').replace(/\\n/g, ''); if (shortdescription.length > 350){ shortdescription = "" + shortdescription.substring(0,250) + "... more"; } $(".descriptionitem").prepend(shortdescription); $(".shortdescription a").click(function() { $(".shortdescription").hide(); $(".originaldescription").slideDown(); return false; }); }); Related content In this: publication By this: publisher By this author: Zhang, Jing ; Ren, Yijin ; Chang, Fang ; Shi, Qiuyi GA_googleFillSlot("Horizontal_banner_bottom");

    ABSTRACT: The solvent effects on the electronic absorption and emission fluorescence spectra for a series of chalcone cyclic analogues were studied. The singlet-state excited dipole moments and the ground state dipole moments of the cyclic chalcone analogues E-2- benzylidene-1-benzosuberone E-2-(4′-methoxybenzylidene)-1-benzosuberone E-2-(4′-dimethylaminobenzylidene)-1-benzosuberone were calculated by using solvatochromic shift method by means of equations using the variations of Stokes’ shift with the solvent's dielectric constant and refractive index values. It was found that the excited state dipole moments calculated by the solvatochromic shift method were greater than the ground state dipole moments indicating a substantial redistribution of the pi-electron densities in a more polar excited state for each derivative.

    ABSTRACT: A novel glutathione-capped cadmium telluride quantum dots-based fluorescence “off–on” sensor was designed and applied for highly sensitive and selective monitoring of histidine in aqueous solution. To provide a platform for histidine detection, manganese ion was first employed as an effective quencher to decrease the fluorescence of glutathione-capped cadmium telluride quantum dots because of the binding of manganese ion to glutathione on the surface of quantum dots and the electron transfer from the photoexcited glutathione-capped cadmium telluride quantum dots to manganese ion. Due to its high binding affinity with manganese ion, histidine can make the manganese ion to be dissociated from the surface of glutathione-capped cadmium telluride quantum dots to form more stable complex with histidine in solution, and set free the luminescent glutathione-capped cadmium telluride quantum dots, thereby recovering the fluorescence of glutathione-capped cadmium telluride quantum dots. Experimental results showed that the recovered fluorescence intensity was directly proportional to the concentration of histidine in the range of 0.006 to 465.0 µg mL−1 with a correlation coefficient (R) of 0.9977, and the detection limit (3σ/K) was 1.82 ng mL−1. Relevant experiments also revealed that the fluorescence sensor gives excellent selectivity for histidine over other common amino acids. To further investigate perfect analysis performance, this sensor was utilized to determine histidine in synthetic samples with satisfactory results.

    ABSTRACT: Silicon oxycarbide thin film was prepared by magnetron sputtering on BK7 glass, namely, K9 glass. And the wavelength dependence of refractive index was determined by the envelop method and Wemple and Didomenico dispersion relationship from transmission spectrum. The wavelength dependence of refractive index was fitted to Cauchy dispersion relationship and the data accorded with Cauchy dispersion relationship very well. Thickness of the film was determined and by comparing the relative standard deviation, we found it could make the result more accurate by fitting the data of refractive index to Cauchy dispersion relationship.

    ABSTRACT: A series of tetravalent cerium ion-doped alkaline-earth-metal tungstate phosphors were prepared by a co-precipitation method with a mixture of ammonium bicarbonate and aqueous ammonia as the precipitating agent. X-ray diffraction, scanning electron microscopy, and photoluminescence were used to characterize the structure, morphology, and luminescent properties of the phosphors. The synthesized cerium-doped tungstate phosphors have a scheelite structure with a pure phase. The scanning electron microscope images show that the grain sizes are in the range from 1.0 to 3.0 µm. Photoluminescence spectra indicate blue emission around 440 nm and the optimized concentrations of tetravalent cerium were 3.0, 2.0, and 3.0 in calcium tungstate, strontium tungstate, and barium tungstate for the highest emission intensities at 365 nm excitation. The Commission Internationale De L'E'clairage chromaticity coordinates of cerium-doped tungstate phosphors, that is, x = 0.14, y = 0.14, exhibit pure blue emission and the synthesized phosphors are promising materials for visual display and solid-state lighting applications.

    ABSTRACT: Microula sikkimensis is a plant rich in γ-linolenic acid. In the present study, samples of M. sikkimensis were digested using a closed-vessel microwave, after which they were analyzed by inductively coupled plasma optical emission spectrometry. The accuracy of the method was confirmed by analysis of a certified reference material of spinach. The study involved 20 samples that were collected in Qinghai–Tibet area. The relative mean concentrations of the 17 elements were as follows: K > Ca > P > Mg > Fe > Al > Na > Ba > Sr > Mn > Zn > B > Ti > Cu > Mo > Ni > Cr. The method is stable and reliable and the results are satisfactory. It is suitable for determination of the concentrations of trace elements in M. sikkimensis. Principal components analysis was applied to study the characteristic elements in M. sikkimensis and six principal components that accounted for 92.15% of the total variance were extracted from the original data. The first two components represented 51.27% of the total variability, indicating that manganese, nickel, molybdenum, strontium, aluminum, iron, and titanium were the characteristic elements in M. sikkimensis. Hierarchical cluster analysis classified samples into five main groups based on the measured parameters.

    ABSTRACT: A new fluorescence enhancement phenomenon in the europium(III)–balofloxacin–sodium dodecyl sulfate system was observed when yttrium(III) was added. Based on this, a sensitive cofluorescence assay for the estimation of balofloxacin was established. Under the optimized conditions, the enhanced fluorescence signal was linear over the concentration of balofloxacin ranging from 3.0 × 10−9 to 7.0 × 10−6 mol L−1 with a correlation coefficient of 0.9993. The detection limit (3 σ) was determined as 8.3 × 10−10 mol L−1. The presented method was successfully applied to determination of balofloxacin in pharmaceutical preparations, human serum, and urine. The possible fluorescence enhancement mechanism was also discussed.

    ABSTRACT: Binding interaction of transition metals copper, cadmium, and mercury with heme proteins were explored using isothermal calorimetry. Consequent conformational changes of the native proteins analyzed by circular dichroic spectroscopy revealed differential structural alteration of heme proteins. But, significant distortion in myoglobin structure was noted due to bioconjugation with mercury whose greater ionic radius may be responsible for this preferential behavior.

    ABSTRACT: Organophosphate inhibits carboxylesterase thus regular treatment includes carboxylesterase oxime reactivator in combination with anti-muscarinic agents. In order to progress the understanding of species differences and to enable an additional reliable extrapolation of animal result to quail a study was initiated to inspect the effect of insecticide compounds, that is, mevinphos, ethoprop, and fenthion, with quail-serum carboxylesterase and common chicken-carboxylesterase. The rate constants for the inhibition of carboxylesterase by these organophosphate and for the aging and spontaneous reactivation of organophosphate-inhibited carboxylesterase enzyme as well as for the oxime-induced reactivation of organophosphate-inhibited carboxylesterase enzyme by the oximes trimedoxime, methoxime, N,N′-(ethano)bis(4-hydroxyiminomethyl)pyridinium methanosulphonate, HI-6, and HLö-7 were determined in this study. Compared to quail-serum carboxylesterase and chick-carboxylesterase displayed a lower sensitivity toward the inspected organophosphate. Furthermore, a slower aging and spontaneous reactivation of quail-serum carboxylesterase enzyme was recorded. The potency of the detected oxime reactivator was remarkably lower with organophosphate-inhibited quail-serum carboxylesterase.

    ABSTRACT: Potash–lime silicate (K2O–CaO–SiO2) glass dated to the Warring States Periods is one of the earliest glass types that have been found in China, but scientific research about this type of glass is scarce at home and abroad. In the present study, a total of 23 potash–lime silicate glass samples of the Warring States Period, excavated from different areas of China, were analyzed noninvasively using a portable X-ray fluorescence spectrometer (pXRF). The chemical composition of these K2O–CaO–SiO2 glasses was analyzed and compared with that of the potash silicate (K2O-SiO2) glasses of the Han Dynasties. The possible raw materials used to make the ancient K2O–CaO–SiO2 glasses were discussed. It appears that the ancient K2O–CaO–SiO2 glasses were produced in China and the potash glasses were of versatile origins. This research provides useful clues to trace the technical development of ancient Chinese glass.

    ABSTRACT: A method for the simultaneous determination of Azorubin and New Red was proposed, which used the synchronous fluorescence spectroscopy coupled with the radial basis function neural networks. The synchronous fluorescence spectra of 59 standards of Azorubin and New Red mixed with concentrations ranging from 5 to 20 µg mL−1 were obtained by synchronous scanning the excitation and emission monochromator maintained at an offset of 70 nm. A method of exploiting the complicated function relationship between the concentrations of Azorubin and New Red and the intensities of their mixtures was discussed according to the accuracies of the radial basis function neural networks predicting results. The final root mean square error is 0.1922 and the total mean relative error is 2.56%. Results show that the method developed is effective, simple, and of satisfactory accuracy.
