    Singapore :Springer Nature Singapore :
    Details
    Keywords: Soil science. ; Environmental chemistry. ; Environment. ; Soil Science. ; Environmental Chemistry. ; Environmental Sciences.
    Description / Table of Contents: Arsenic hyperaccumulator Pteris Vittata L. and its arsenic accumulation -- Arsenic hyperaccumulation mechanisms: absorption, transportation and detoxification -- Establishment of phytoremediation technology for arsenic contaminated sites -- Application of phytoremediation technology to typical mining sites in China -- Enhancement of arsenic removal in phytoremediation of arsenic contaminated soils.
    Abstract: This book introduces readers to the main theories of phytoremediation and its application to arsenic-contaminated soils in China. The hyperaccumulation theories are introduced, including the use of hyperaccumulators to remove large amounts of arsenic without producing toxic symptoms. The use of synchrotron-based X-ray absorption fine structure radiation to disclose the hyperaccumulation mechanism – a method that makes it possible to detect the elements in plant tissues without destroying the sample – is introduced in detail. This book also includes practical application cases of phytoremediation, which are rarely found in the literature. Allowing readers to gain a thorough understanding of phytoremediation technology, and demonstrating its efficiency in cleaning arsenic-contaminated soils, the book offers a valuable asset for graduate students, lecturers, researchers and engineers in the field of soil remediation. .

    Abrupt Climate Transition from Snowball to Moist or Runaway Greenhouse, links to model results in NetCDF format (2017)
    PANGAEA
    In:  Supplement to: Yang, Jun; Ding, Feng; Ramirez, Ramses M; Peltier, W R; Hu, Yongyun; Liu, Yonggang (2017): Abrupt climate transition of icy worlds from snowball to moist or runaway greenhouse. Nature Geoscience, 10(8), 556-560, https://doi.org/10.1038/ngeo2994

    Description: Ongoing and future space missions aim to identify potentially habitable planets in our Solar System and beyond. Planetary habitability is determined not only by a planet's current stellar insolation and atmospheric properties, but also by the evolutionary history of its climate. It has been suggested that icy planets and moons become habitable after their initial ice shield melts as their host stars brighten. Here we show from global climate model simulations that a habitable state is not achieved in the climatic evolution of those icy planets and moons that possess an inactive carbonate-silicate cycle and low concentrations of greenhouse gases. Examples for such planetary bodies are the icy moons Europa and Enceladus, and certain icy exoplanets orbiting G and F stars. We find that the stellar fluxes that are required to overcome a planet's initial snowball state are so large that they lead to significant water loss and preclude a habitable planet. Specifically, they exceed the moist greenhouse limit, at which water vapour accumulates at high altitudes where it can readily escape, or the runaway greenhouse limit, at which the strength of the greenhouse increases until the oceans boil away. We suggest that some icy planetary bodies may transit directly to a moist or runaway greenhouse without passing through a habitable Earth-like state.

    Electrical characteristics and thermal stability of n+ polycrystalline- Si/ZrO2/SiO2/Si metal–oxide–semiconductor capacitors (2002)

    Notes: We have investigated the thermal stability of n+ polycrystalline-Si(poly-Si)/ZrO2(50–140 Å)/SiO2(7 Å)/p-Si metal–oxide–semiconductor (MOS) capacitors via electrical and material characterization. The ZrO2 gate dielectric was prepared by atomic layer chemical vapor deposition using ZrCl4 and H2O vapor. Capacitance–voltage hysteresis as small as ∼12 mV with the flatband voltage of −0.5 V and the interface trap density of ∼5×1010 cm−2 eV−1 were attained with activation anneal at 750 °C. A high level of gate leakage current was observed at the activation temperatures over 750 °C and attributed to the interfacial reaction of poly-Si and ZrO2 during the poly-Si deposition and the following high temperature anneal. Because of this, the ZrO2 gate dielectric is incompatible with the conventional poly-Si gate process. In the MOS capacitors having a smaller active area (〈50×50 μm2), fortunately, the electrical degradation by further severe silicidation does not occur up to an 800 °C anneal in N2 for 30 min. © 2002 American Institute of Physics.

    Boron penetration and thermal instability of p+ polycrystalline-Si/ZrO2/SiO2/n-Si metal-oxide-semiconductor structures (2002)

    Notes: We report boron penetration and thermal instability of p+ polycrystalline-Si (poly-Si)/ZrO2 (100 Å)/SiO2 (∼7 Å)/n-Si metal-oxide-semiconductor (MOS) structures. The flatband voltage shift (ΔVFB) of the p+ poly-Si/ZrO2/SiO2/n-Si MOS capacitor as determined by capacitance–voltage measurement was ∼0.18 V, corresponding to a p-type dopant level of 1.1×1012 B ions/cm2 as the activation temperature increased from 800 to 850 °C. Additional ΔVFB of ∼0.24 V was measured after the anneal from 850 to 900 °C. Noticeable boron penetration into the n-type Si channel as observed by secondary ion mass spectroscopy also confirmed the VFB instability with activation annealing above 850 °C. An abnormal decrease of accumulation capacitance was also found after anneal at 900 °C due to an excessive leakage current which was attributed to the formation of ZrSix nodules at the poly-Si/ZrO2 interface. We observed 4–5 orders of magnitude lower leakage current from the small-size capacitors (〈50×50 μm2) up to the activation anneal of 850 °C for 30 min, while the formation of interfacial ZrSix nodules at 900 °C cannot be avoidable even at 0.6-μm-wide gate lines. © 2002 American Institute of Physics.

    Variation of magnetic properties as a function of Mo content in the RFe12−xMox series and their nitrides (R=Y, Nd, Gd) (1995)

    Notes: The structure and magnetic properties of RFe12−xMox series and their nitrides with R=Y,Gd,Nd and x=0.8,1.0,1.5,2.0,2.5 have been studied by x-ray-diffraction and magnetic measurements. It is found that with the increment of Mo content x, the lattice parameters increase, whereas the saturation magnetization, Curie temperature, and anisotropy field decreases in the RFe12−xMox series. Upon nitrogenation lattice parameters, saturation magnetization, and Curie temperature increase. Correspondingly, the easy c-axis magnetocrystalline anisotropy of the Fe sublattice decreases in YFe12−xMoxNy and GdFe12−xMoxNy but increases in NdFe12−xMoxNy although its variation with the Mo content is the same as in their original counterparts. NdFe12−xMoxNy compound in the low Mo content shows great potential for permanent magnet applications. © 1995 American Institute of Physics.

    Formation and magnetic properties of TbCu7-type RFe7 compounds and their nitrides (R=Tb and Dy) : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: DyFex and TbFex alloys with x=7, 7.7, and 9 were mechanically alloyed followed by annealing in an attempt to prepare TbCu7-type DyFe7 and TbFe7 compounds. X-ray-diffraction and thermomagnetic measurements show that single-phase TbCu7-type TbFe7 can be obtained for all three compositions, while DyFe7 was formed for x=7.7 and 9 when annealed in the temperature range from 650 to 850 °C. The Curie temperature (Tc) of the TbCu7-type phase shows no obvious variation with Fe content, but decreases with annealing temperature. For DyFe7.7 and TbFe7.7, their respective Curie temperatures are reduced from 160 and 185 °C by annealing at 700 °C for 3 h to 140 and 160 °C after annealing at 850 °C for 3 h. Magnetometry measurements reveal that the TbCu7-type phase is a soft phase with a room-temperature coercivity of less than 500 Oe. Nitriding the TbCu7-type phase results in lattice expansions without changing the crystal structure. However, nitriding increases the Curie temperatures dramatically to 465 and 450 °C for TbFe7.7Ny and DyFe7.7Ny, respectively. Furthermore, nitriding greatly enhanced the coercivities of TbCu7-type compounds, reaching values of 3.75 and 4.0 kOe for TbFe7.7Ny and DyFe7.7Ny, respectively. The nitrides with optimum coercivities are single-phase TbCu7-type compounds with an average grain size of 10–15 nm as estimated from Bragg peak broadening. A coercivity mechanism based on contributions from the random anisotropy of the R3+ ions and the crystalline anisotropy is proposed to explain the observed effects.© 1997 American Institute of Physics.
