[Ti] Título:Iron-Doped BaMnO for Hybrid Water Splitting and Syngas Generation.

[Ab] Resumo:A rationalized strategy to optimize transition-metal-oxide-based redox catalysts for water splitting and syngas generation through a hybrid solar-redox process is proposed and validated. Monometallic transition metal oxides do not possess desirable properties for water splitting; however, density functional theory calculations indicate that the redox properties of perovskite-structured BaMn Fe O can be varied by changing the B-site cation compositions. Specifically, BaMn Fe O is projected to be suitable for the hybrid solar-redox process. Experimental studies confirm such predictions, demonstrating 90 % steam-to-hydrogen conversion in water splitting and over 90 % syngas yield in the methane partial-oxidation step after repeated redox cycles. Compared to state-of-the-art solar-thermal water-splitting catalysts, the rationally designed redox catalyst reported is capable of splitting water at a significantly lower temperature and with ten-fold increase in steam-to-hydrogen conversion. Process simulations indicate the potential to operate the hybrid solar-redox process at a higher efficiency than state-of-the-art hydrogen and liquid-fuel production processes with 70 % lower CO emissions for hydrogen production.

[Ab] Resumo:For situations with radioactive material out of control where it may be physically difficult or prohibited to access areas close to the source, measurements from distance may be the only way to assess the radiation environment. Using collimated detectors will provide means to locate the direction of the radiation from the source. To investigate the possibilities of mapping gamma emitting radioactive material in a closed non-enterable area, a tentative system for mapping radioactive materials from a distance was built. The system used a computer controlled cylindrical rotating slit collimator with a high purity germanium detector placed in the cylinder. The system could be placed on a car-towed trailer, with the centre of the detector about 1.4 m above ground. Mapping was accomplished by the use of a specially developed image reconstruction algorithm that requires measurements from two or more locations around the area to be investigated. The imaging capability of the system was tested by mapping an area, 25 by 25 m , containing three 330 MBq Cs point sources. Using four locations outside the area with about 20 min measuring time in each location and applying the image reconstruction algorithm on the deconvoluted data, the system indicated the three source locations with an uncertainty of 1-3 m. The results demonstrated the potential of using collimated mobile gamma radiometry combined with image reconstruction to localize gamma sources inside non-accessible areas.

[Ab] Resumo:A microwave-induced plasma optical emission spectrometer with N -based plasma was combined with a multimode sample introduction system (MSIS) for hydride generation (HG) and multielemental determination of As, Bi, Ge, Sb, and Sn in samples of forage, bovine liver, powdered milk, agricultural gypsum, rice, and mineral fertilizer, using a single condition of prereduction and reduction. The accuracy of the developed analytical method was evaluated using certified reference materials of water and mineral fertilizer, and recoveries ranged from 95 to 106%. Addition and recovery experiments were carried out, and the recoveries varied from 85 to 117% for all samples evaluated. The limits of detection for As, Bi, Ge, Sb, and Sn were 0.46, 0.09, 0.19, 0.46, and 5.2 µg/L, respectively, for liquid samples, and 0.18, 0.04, 0.08, 0.19, and 2.1 mg/kg, respectively, for solid samples. The method proposed offers a simple, fast, multielemental, and robust alternative for successful determination of all five analytes in agricultural samples with low operational cost without compromising analytical performance.

[Ti] Título:Synthesis and Screening of Phase Change Chalcogenide Thin Film Materials for Data Storage.

[Ab] Resumo:A combinatorial synthetic methodology based on evaporation sources under an ultrahigh vacuum has been used to directly synthesize compositional gradient thin film libraries of the amorphous phases of GeSbTe alloys at room temperature over a wide compositional range. An optical screen is described that allows rapid parallel mapping of the amorphous-to-crystalline phase transition temperature and optical contrast associated with the phase change on such libraries. The results are shown to be consistent with the literature for compositions where published data are available along the Sb Te -GeTe tie line. The results reveal a minimum in the crystallization temperature along the Sb Te -Ge Te tie line, and the method is able to resolve subsequent cubic-to-hexagonal phase transitions in the GST crystalline phase. HT-XRD has been used to map the phases at sequentially higher temperatures, and the results are reconciled with the literature and trends in crystallization temperatures. The results clearly delineate compositions that crystallize to pure GST phases and those that cocrystallize Te. High-throughput measurement of the resistivity of the amorphous and crystalline phases has allowed the compositional and structural correlation of the resistivity contrast associated with the amorphous-to-crystalline transition, which range from 5-to-8 orders of magnitude for the compositions investigated. The results are discussed in terms of the compromises in the selection of these materials for phase change memory applications and the potential for further exploration through more detailed secondary screening of doped GST or similar classes of phase change materials designed for the demands of future memory devices.

[Ti] Título:Less-studied TCE: are their environmental concentrations increasing due to their use in new technologies?
[So] Source:Chemosphere;182:605-616, 2017 Sep.
[Is] ISSN:1879-1298
[Cp] País de publicação:England
[La] Idioma:eng
[Ab] Resumo:The possible environmental impact of the recent increase in use of a group of technology-critical elements (Nb, Ta, Ga, In, Ge and Te) is analysed by reviewing published concentration profiles in environmental archives (ice cores, ombrotrophic peat bogs, freshwater sediments and moss surveys) and evaluating temporal trends in surface waters. No increase has so far been recorded. The low potential direct emissions of these elements, resulting from their absolute low production levels, make it unlikely that the increasing use of these elements in modern technology has any noticeable effect on their environmental concentrations on a global scale. This holds particularly true for those of these elements that are probably emitted in relatively high amounts from other human activities (i.e., coal combustion and non-ferrous smelting), such as In, the most studied element of the group.

[Ti] Título:Optimization of the marinelli beaker dimensions using genetic algorithm.

[La] Idioma:eng
[Ab] Resumo:A computational code, based on the genetic algorithm and MCNPX version 2.6 code was developed and used to investigate the effects of some important parameters of HPGe detector (such as Al cap thickness, dead-layer thickness and Ge hole size) on optimum dimensions of marinelli beaker. In addition, the effects of detector material on optimal beaker dimensions were also investigated. Finally, the optimized beaker dimensions at various beaker volumes (300, 500, 700, 1000 and 1500 cm ) were determined for some conventional Ge detectors with different crystal sizes (16 sizes). These sets of data then were used to drive mathematical formulas (obtained by best fitting to data sets). The results showed that, there is no meaningful correlation between the optimum dimensions of the beaker and each of the dead-layer thickness, Al cap thickness and the Ge-crystal hole size. On the other hand, the optimum beaker radius increases with decreasing the density of the detector material while the beaker height decreases.

[Ab] Resumo:Trace elements, including zinc (Zn) and germanium (Ge), are essential for health; deficiency or excess levels of trace elements results is harmful. As a result of industrial and agricultural production, Pb widely exists in people's living environment. It is absorbed mainly through the respiratory and digestive tracts, producing systemic harm. Reference values for a normal, healthy population are necessary for health assessment, prevention and treatment of related diseases, and evaluation of occupational exposures. Reference ranges for the Chinese population have not been established. From March 2009 to February 2010; we collected data and blood samples ( = 1302) from residents aged 6-60 years living in Shandong Province, China. We measured blood concentrations of Zn, Ge, and Pb using inductively coupled plasma mass spectrometry to determine reference ranges. Results were stratified by factors likely to affect the concentrations of these trace elements: sex, use of cosmetics or hair dye, age, alcohol intake, smoking habits, and consumption of fried food. The overall geometric mean (GM) concentrations (95% confidence interval) were 3.14 (3.08-3.20) mg/L for Zn, 19.9 (19.3-20.6) µg/L for Ge, and 24.1 (23.2-25.1) µg/L for Pb. Blood Zn concentrations were higher in women than in men ( < 0.001), while the opposite was found for Pb ( < 0.001) and sex did not influence Ge ( = 0.095). Alcohol use was associated with higher blood concentrations of Zn ( = 0.002), Ge ( = 0.002), and Pb ( = 0.001). The GM concentration of Zn was highest in 20-30-year-olds ( < 0.001), while Pb concentrations were highest in 12-16-year-olds ( < 0.001). Use of hair dye was associated with lower blood concentrations of Ge ( < 0.05). GM blood concentrations of Pb differed significantly between those who consumed fried foods 1-2 times/month (18.7 µg/L), 1-2 times/week (20.9 µg/L), and every day (28.5 µg/L; < 0.001). Blood Pb concentrations were higher in subjects who used cosmetics ( < 0.05), hair dye ( < 0.05), and who smoked cigarettes ( < 0.001) than in those who did not.

[Ab] Resumo:We present a novel four-layer structure consisting of bottom, second, third, and surface layers in the sensing region, for a D-shaped step-index fiber-optic evanescent wave (FOEW) sensor. To reduce the background noise, the surface of the longitudinal section in the D-shaped region is coated with a light-absorbing film. We check the morphologies of the second and surface layers, examine the refractive indices (RIs) of the third and surface layers, and analyze the composition of the surface layer. We also investigate the effects of the thicknesses and RIs of the third and surface layers and the LA film on the light transmission and sensitivity of the FOEW sensors. The results highlight the very good sensitivity of the proposed FOEW sensor with a four-layer structure, which reached -0.077 (µg/l) in the detection of the target antibody; the sensitivity of the novel FOEW sensor was 7.60 and 1.52 times better than that of a conventional sensor with a core-cladding structure and an FOEW sensor with a three-layer structure doped with GeO . The applications of this high-sensitivity FOEW sensor can be extended to biodefense, disease diagnosis, and biomedical and biochemical analysis.

[Ab] Resumo:Hydrophobic interaction, as well as polar interactions such as hydrogen bonding and electrostatic interaction, plays an essential role in the interaction between biologically active compounds and their target molecules. Therefore, the application of novel hydrophobic structures other than simple hydrocarbons or aromatic rings is expected to be useful in the development of biologically active compounds with distinctive chemical and pharmacological properties. In this study, we developed various bioactive compounds bearing a boron cluster, silicon-containing or germanium-containing functionalities as novel hydrophobic structures. Regarding the boron cluster-based compounds, we developed highly potent nonsteroidal androgen receptor (AR) antagonists, progesterone receptor (PR) antagonists, and non-secosteroidal vitamin D receptor (VDR) agonists. Regarding the Group 14 elements, we systematically determined hydrophobicity parameters of various trialylmethyl, trialkylsilyl and trialkylgermyl substituents, and revealed that silicon and germanium containing compounds exhibited higher hydrophobicity than the corresponding carbon analogues, with a difference in log P value of approximately 0.6, independent of the alkyl species. We also revealed that sila- and germa-substitution of carbon could enhance their biological activity. Furthermore, we demonstrated that silyl substructures could function as mimetics of cis-diatomic substructures. These results are expected to expand the chemical space of hydrophobic pharmacophores and thus contribute to the development of novel and distinctive drug candidates.

[Ti] Título:Effects of Ge-132 and GeO on seed germination and seedling growth of Oenothera biennis L. under NaCl stress.

[Ab] Resumo:To investigate the effects of ß-carboxyethyl germanium sequioxide (Ge-132) and germanium dioxide (GeO ) on improving salt tolerance of evening primrose (Oenothera biennis L.), seed germination, seedling growth, antioxidase and malondialdehyde (MDA) were observed under treatments of various concentrations (0, 5, 10, 20, 30 µM) of Ge in normal condition and in 50 mM NaCl solution. The results showed that both Ge-132 and GeO treatments significantly increased seed germination percentage and shoot length in dose-dependent concentrations but inhibited early root elongation growth. 5-30 µM Ge-132 and 10, 20 µM GeO treatments could significantly mitigate even eliminate harmful influence of salt, representing increased percentage of seed germination, root length, ratio between length of root and shoot, and decreased shoot length. These treatments also significantly decreased peroxidase (POD) and catalase (CAT) activities and MDA content. The mechanism is likely that Ge scavenges reactive oxygen species - especially hydrogen peroxide (H O ) - by its electron configuration 4S 4P so as to reduce lipid peroxidation. This is the first report about the comparison of bioactivity effect of Ge-132 and GeO on seed germination and seedling growth under salt stress. We conclude that Ge-132 is better than GeO on promoting salt tolerance of seed and seedling.
