    ABSTRACT: Spectroscopic Fourier self-deconvolution analysis was used to investigate β-sheet features in the secondary structure of hemoglobin under mobile phone microwaves at 900 MHz. To this end, four samples of hemoglobin in bidistilled water, sucrose, trehalose, and sodium chloride aqueous solutions were exposed for up to 4 hr to 900 MHz microwaves at an average H-field intensity of 42 mA/m. Quantitative spectral analyses highlighted significant increases in β-sheet contents in the Amide I region of hemoglobin samples in bidistilled water solution, but no appreciable change was observed in hemoglobin samples in sucrose, trehalose, and sodium chloride solutions. These results led us to conclude that mobile phone microwaves can denaturate hemoglobin in bidistilled water solution whereas sucrose, trehalose, and sodium chloride solutions produce a protective effect against microwaves, preserving the protein from unfolding.

    ABSTRACT: The compositions of plaster, pigments, and binding medium were identified using micro-Raman spectroscopy, scanning electron microscopy coupled with energy-dispersive X-ray, and gas chromatograph-mass spectrometer. The results show that the plaster was calcium carbonate; the red color was ascribed to hematite; the blue pigment was ultramarine; the black pigment was carbon; and the yellow pigment was litharge. Animal glue as the binding medium was mixed in the pigments. Dissolved salt (mirabilite) was confirmed on the tomb passage. The mural detachment was detected with portable infrared thermal imager, and this damage resulted from the soil layer. This will serve as the basis for repairing the murals and reliable methods for identifying ancient murals.

    ABSTRACT: The aromatic character, distortion, and stabilization as a result of single and double protonation of 3-aminopyridine like three different complex salts were studied by infrared-, ultraviolet spectral analysis, proton nuclear magnetic resonance, and quantum chemical ab initio calculations. Linear-dichroic infrared spectroscopy was applied for identification of the infrared bands. The correlation structure-spectroscopic properties of the model systems are determined: bis(3-aminopyridinium) tetrachlorocuprate (II) salt, where the ring nitrogen atom participates in protonation; 3-ammoniumpyridinium tetrachlorocuprate (II) salt, where both nitrogen atoms are protonated; and a complex with copper (II) bis(3-aminopyridinium) hexachlorodicuprate (II), where the metal ion is coordinated through amino group.

    ABSTRACT: We have studied the mineral kaliborite. The sample originated from the Inder B deposit, Atyrau Province, Kazakhstan, and is part of the collection of the Geology Department of the Federal University of Ouro Preto, Minas Gerais, Brazil. The mineral is characterized by a single intense Raman band at 756 cm−1 assigned to the symmetric stretching modes of trigonal boron. Raman bands at 1229 and 1309 cm−1 are assigned to hydroxyl in-plane bending modes of boron hydroxyl units. Raman bands are resolved at 2929, 3041, 3133, 3172, 3202, 3245, 3336, 3398, and 3517 cm−1. These Raman bands are assigned to water stretching vibrations. A very intense sharp Raman band at 3597 cm−1 with a shoulder band at 3590 cm−1 is assigned to the stretching vibration of the hydroxyl units. The Raman data are complimented with infrared data and compared with the spectrum of kaliborite downloaded from the Arizona State University database. Differences are noted between the spectrum obtained in this work and that from the Arizona State University database. This research shows that minerals stored in a museum mineral collection age with time. Vibrational spectroscopy enhances our knowledge of the molecular structure of kaliborite.

    ABSTRACT: The mineral lamprophyllite is fundamentally a silicate based upon tetrahedral siloxane units with extensive substitution in the formula. Lamprophyllite is a complex group of sorosilicates with general chemical formula given as A2B4C2Si2O7(X)4, where the site A can be occupied by strontium, barium, sodium, and potassium; the B site is occupied by sodium, titanium, iron, manganese, magnesium, and calcium. The site C is mainly occupied by titanium or ferric iron and X includes the anions fluoride, hydroxyl, and oxide. Chemical composition shows a homogeneous phase, composed of Si, Na, Ti, and Fe. This complexity of formula is reflected in the complexity of both the Raman and infrared spectra. The Raman spectrum is characterized by intense bands at 918 and 940 cm−1. Other intense Raman bands are found at 576, 671, and 707 cm−1. These bands are assigned to the stretching and bending modes of the tetrahedral siloxane units.

    ABSTRACT: In new-generation hyperspectral sensors, the electronic noise is not dominant and the photon noise has to be taken into account. Therefore, a parametric model that accounts for both signal-dependent and signal-independent noise on the useful signal is established. A novel algorithm to estimate the parameters of the model is proposed, which consists of two steps. First, the residual image is calculated by the multiple linear regression in spectral domain to decouple the strong spectral correlation. Then, local sample statistics of the hyperspectral image and its residual image are calculated, and the system of linear equations with respect to the signal-dependent and signal-independent noise variances is established. The least square solution of the equations is the estimation of the signal-dependent and signal-independent noise variances. Experiments on the simulated hyperspectral data analyze the accuracy of the method and experiments on the real-life data show its effectiveness.

    ABSTRACT: First-principles calculations are used to study the electronic structure of the TiO2(101) surface. The effect of oxygen vacancies and interstitial titanium ions on the electronic structure is investigated, and models for optical single-electron charge transfer transitions in the structure are proposed. We found that the addition of an uncharged oxygen vacancy leads to a shift of the total density of states toward lower energy, and the bandgap increases. Therefore, interstitial titanium ion incorporation induces donor states above the valence band and increases the bandgap. These results can be used to explain the observed blueshift in nanoscale TiO2.

    ABSTRACT: Spectral Neugebauer model is widely used for spectral reflectance prediction during printer characterization. However, several factors reduce the predication precision. Thus, an improved cellular Yule-Nielson spectral Neugebauer (CYNSN) model is proposed, which modifies the traditional spectral Neugebauer model in three main aspects: (1) First, in order to adjust the nonlinearities between the predicated and measured spectral reflectance, an iteratively calculated Yule-Nielson exponent is added to the reflectance values within the Neugebauer equations. (2) Second, the quantity of Neugebauer primaries is increased by dividing the CMY colorant space into 43 uniform cellular subdomains. (3) Third, the mapping functions are developed to map the area coverages' theoretical values to their effective values within the subdomains, and the mapped values highly improve the matching degree of the predicated and measured reflectance values. In the experiment, four related spectral Neugebauer models are employed during printer characterization, which are the traditional spectral Neugebauer model, Yule-Nielson spectral Neugebauer (YNSN) model, traditional CYNSN model, and the modified CYNSN model, respectively. And the experimental results show the modified CYNSN model yields a significant improvement over the other spectral Neugebauer models, by comparing the characterization errors in the form of colorimetry and spectroscopy.

    ABSTRACT: The presence of blood contamination could affect the chemical characterization of mineral trioxide aggregates as endodontic repair material during surgical approach. The aim of this study was to assess and compare the chemical characterization of two white mineral trioxide aggregates (ProRoot and Angelus) mixed with blood versus water. ProRoot and Angelus were mixed with either distilled water, fresh human blood, or diluted blood and analyzed using Fourier transform infrared spectroscopy. The same materials were packed inside holes in dentin blocks for scanning electron microscopy with energy-dispersive X-ray. Gray Portland cement was used as a control. The infrared spectra of unhydrate powders showed an increase in alite in ProRoot and Angelus, belite in Portland cement, and calcium hydroxide in Angelus. Upon hydration, changes in these bands were detected. Energy-dispersive X-ray displayed significantly higher calcium, aluminum, and phosphorous in hydrated Angelus and silicon in hydrated ProRoot (p < 0.05). No phosphorous was detected in ProRoot. Traces of iron were detected in blood groups. A granular pattern was observed at the hydrated material of all tested groups. Definitive gaps were detected at certain areas within hydrated material and its dentin-interface, particularly in blood-contaminated groups. It was supported with the appearance of new bands assigned to Amide I and II of blood protein. It was concluded that the presence of blood during the hydration process of mineral trioxide aggregates produced small gaps of protein impurities within the hydrated material, affecting its chemical behavior and dentin/material-interface integrity.

    ABSTRACT: Animal and plant wastes contain recoverable phosphorus that can be repurposed as fertilizer. Ultraviolet-visible spectroscopy and inductively coupled plasma optical emission spectroscopy are compared for the measurement of phosphorus in salt solutions, then wastes. There is no impact of nitrate or chloride on phosphate measurements by ultraviolet-visible spectroscopy, but high concentrations interfere with phosphorus measurement by inductively coupled plasma optical emission spectroscopy. Greenhouse and swine waste can be analyzed by either technique, but more dilution is required for analysis by ultraviolet-visible spectroscopy and for swine waste. Swine waste has ∼8 times more phosphorus than greenhouse waste and is the more viable waste source for phosphorus recovery.

    ABSTRACT: A novel method based on the enhancement effect of room temperature ionic liquids for hollow-fiber liquid-phase microextraction trace amounts of mercury combined with UV–Vis spectrophotometry for the determination of Hg was developed. The addition of room temperature ionic liquids led to 6.0 times improvement in the determination of mercury. Under optimized conditions, an enrichment factor of 120 could be obtained, and the detection limit for Hg was 0.2 ng mL−1. The relative standard deviations for five replicate determinations of 20 ng mL−1 Hg(II) was 5.4%. The proposed method was successfully applied to certified reference materials and environmental water samples with satisfactory results for the determination of Hg.

    ABSTRACT: The contents of macro- and microelements in cow, goat, and human milk from Croatia were measured and compared for the first time. The highest concentrations of element were measured in milk cow: calcium 1.4 g/kg, sodium 0.6 g/kg, zinc 4.0 mg/kg, strontium 0.4 mg/kg; goat: magnesium 0.2 g/kg, potassium 2.2 g/kg, iron 0.8 mg/kg, manganese 71 µg/kg, selenium 35 µg/kg, molybdenum 20 µg/kg, chromium 72 µg/kg, lithium 14 µg/kg; and human: copper 193 µg/kg. Equal content of molybdenum (20 µg/kg) was determined in cow and goat milk. Significant differences in element levels between the three species were determined. Concentrations of magnesium, manganese, selenium, chromium, and lithium in goat milk were significantly higher than in cow milk. Significantly lower levels of calcium, potassium, sodium, magnesium, zinc, selenium, and strontium were determined in human milk than in cow and goat milk. Chromium content was significantly higher in goat than in human milk. Copper content in human milk was significantly higher than in cow milk. Correlations, mostly moderate and positive, were found between elements in cow and goat milk.

    ABSTRACT: The laser breakdown time-of-flight mass spectrometry was developed and applied to detect the breakdown patterns of hydrocarbons that are significant to improve the detectability of heavy metals compounded in various mixtures such as particles and hydrocarbons. The laser wavelength dependence of this method was evaluated using 1064, 532, and 266 nm laser outputs. Breakdown processes using 1064 and 532 nm outputs showed less interference of fragmentation for the detection of various heavy metals. The method was applied to various hydrocarbons and it showed the possibility of categorization of hydrocarbon groups using the pattern of breakdown products.

    ABSTRACT: Zinc oxide/high-density polyethylene nanocomposites with high-UV-shielding efficiency were reported. Zinc oxide nanoparticles were synthesized by the homogeneous precipitation method and calcination of the precursor at different temperatures. Zinc oxide/high-density polyethylene nanocomposites were subsequently prepared from high-density polyethylene and as-prepared zinc oxide nanoparticles via melt mixing process. The structural properties of the as-prepared zinc oxide nanoparticles and nanocomposites were studied in detail using X-ray diffractometer, Fourier transform infrared spectrometer, thermogravimetry, differential scanning calorimeter, ultrasonic pulse echo technique, scanning electron microscopy, and transmission electron microscope. The optical properties of the obtained nanocomposites were shown to depend on zinc oxide particle size and content. The nanocomposite containing zinc oxide nanoparticles with an average particle size of 25.22 nm after calcination at 350°C was found to have the most optimal optical properties, namely high-visible light transparency and high-UV light shielding efficiency, which are desirable for many important applications.

    ABSTRACT: The formation of a manganese (II) coordination supramolecular polymer was studied by resonance light scattering spectra for manganese (II) detection. Bis-sulfosalophen (a ditopic tetradentate Schiff base ligand) and bis-phenanthroline-glutaraldehyde (a ditopic bidentate ligand) were prepared for the construction of the supramolecular polymer. In a procedure of manganese (II) detection, manganese (II) ion reacts with bis-sulfosalophen to form a binuclear manganese (II) complex. The binuclear complex then self-assembles with bis-phenanthroline-glutaraldehyde to form the supramolecular polymer, resulting in the production of strong resonance light scattering signal. The amount of manganese was detected by measuring the resonance light scattering intensity. Under optimal conditions, a linear range was found to be 0.5–50.0 ng/mL, with a detection limit of 0.1 ng/mL. The method has been successfully applied to determine manganese in vegetable and tea samples with relative standard deviations of less than 5% and recoveries of 95.8–105.7%.
