  • Hydrochar enhances growth of poplar for bioenergy while

    Leakage refers to the situation in which a C sequestration measure, directly or indirectly, triggers an activity, which in whole or part, counteracts the C effects of the initial activity. When C storage is followed by release within a couple of months or years, it cannot be considered permanent.

  • A global meta‐analysis of forest bioenergy greenhouse gas

    Leakage, defined as activity shifting in the presence of a biomass project (Henders Ostwald, 2012), has the potential to drive forest harvest outside the project area to continue meeting a priori economic demand for biomass (e.g. wood products).

  • An explicit MPS/FEM coupling algorithm for three

    2020-12-1Currently, accurate simulations of fluid structure interaction (FSI) problems still remain a challenging task in the academic community. The purpose of this work is to develop a three-dimensional (3D) coupling algorithm to achieve the end, where the explicit moving particle simulation method (MPS) and the finite element method (FEM) are respectively employed to account for fluid flows and

  • Sulfur Hexafluoride monitor for High Speed Rail

    The principle of sulfur hexafluoride leak detector is as follows: when the concentration of sulfur hexafluoride gas contained in the air changes, the degree of ionization of the mixed gas under the action of high-frequency electromagnetic field will also be different, and the concentration of sulfur hexafluoride can be reflected by detecting the ionization degree.

  • Trapping and preconcentration of volatile organic sulfur

    2020-5-24Three low-to-high temperature cycles were applied to all adsorption tubes as a preconditioning procedure prior to sample analysis. The values of the high temperature for each sorbent can be found in Table S2 of the SI. The sorbents were held at a high temperature for at least 15 min. 2.4. Hydrophobicity of adsorbents
