Identification of natural gas genesis and source for high-matured multiple gases is a great challenge in the exploration deep–ultra deep unconventional gases. In this paper, identification method system enriched through new experimental techniques comprehensive analysis geological data. New indexes charts were determined to distinguish sapropelic kerogen degraded oil cracking gas, accumulated scattered liquid hydrocarbon different evolution stages, nitrogen, carbon dioxide organic inorganic...
Energetic materials (EMs) are a group of special energy materials, and it is generally full safety risks costs much to create new EMs. Thus, machine learning (ML)-aided discovery becomes highly desired for EMs, as ML good at risk cost reduction. This work decodes hexanitrobenzene (HNB) 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) two distinctive energetic nitrobenzene compounds by ML, in combination with theoretical calculations. Based on series accurate models density, heat formation, bond...
Abstract In this study, a detailed analysis of 20 per- and polyfluoroalkyl substances (PFAS) was conducted, in different environmental media the Fu River, main sewage storage body, located near Tianhe Airport Wuhan, China. The PFAS included 13 perfluorocarboxylic acids (C4–C18), four perfluorosulfonic (C4, C6, C8, C10), three PFAS. surface water samples, short-chain perfluorobutanesulfonic acid (PFBS) perfluorobutanoic were most prevalent highest concentrations, 168 ng/L 49.7 ng/L,...
Molecular dynamics simulations are performed to explore nanoindentation characteristics of tungsten, and the influences grain size, indenter velocity, temperature discussed. The results illustrate that hardness reduces as size (5.00 ∼ 24.62 nm) decreases. There is no phase change observed during whole deformation process. For monocrystalline W, dislocation nucleation propagation dominate mechanisms. Differently, primary mode nanocrystalline W split motion GBs. Dislocations primarily nucleate...
To improve the economic and safety aspects of tunnel structure design, this paper studies mechanical properties steel fiber reinforced concrete (SFRC) secondary lining structures optimizes support parameters based on optimized SFRC mix proportions. The research involves scaled model experiments finite element analysis to study cracking process, deformation characteristics, stress distribution linings under different loading conditions.Using ABAQUS software, simulations were conducted with...
The present work concerns a basic issue in molecular science, i.e., constructing high energy isomer with given composition. Three compositions of CH3NO2, CH4N2O2, and CH3NO3 are adopted to construct various isomers the internal calculated compared ascertain its dependence on linking order atoms. Thereby, simple rule for CHNO is summarized. separation reducing C/H atoms oxidizing O by N as well direct linkage C-C, C-H, O-O, benefits energy; other hand, O-O leads low stability, thus double...
During eating, the teeth usually endure sharply temperature changes because of different foods. It is importance to investigate heat transfer and dissipation behavior dentino-enamel junction (DEJ) human tooth since dentine enamel have thermophysical properties. The spatial temporal distributions on enamel, dentine, pulpal chamber both its discontinuous boundaries, were measured using infrared thermography a stepped increase outer boundary crowns. thermal diffusivities for deduced from time...
Abstract A 3D geomechanical model is built for the XGS field, located in Sichuan province, onshore China. The field a faulted anticline consisting of three main reservoir layers. reservoirs are crest an structure bounded between major revers faults. captures all structural complexities and spatial variation properties parameters entire field. using interpreted horizons faults form surface seismic tied to markers from well data. grid constructed extended ground level, use as framework model....
A synergic photocatalysis/halogen-atom-transfer strategy offers a mild, sustainable, and practical method for the carboalkylation of electron-deficient alkenes using CO 2 as C1 source commercially available alkyl iodides building blocks.
The method of interposing a thin layer immiscible organic solvent (benzonitrile, BN) between glassy carbon electrode surface and an aqueous solution has been successfully applied to study the reaction highly hydrophobic molecule, 2,3,6,7,10,11-hexaphenylhexazatriphenylene (HAT). Four couples well-defined redox peaks HAT were observed at BN layer-coated in N2-saturated 2 M HClO4 solution. By cyclic voltammetry, square-wave normal pulse thermodynamic kinetic parameters (i.e., formal potential,...
Tensile strength is a key parameter governing tensile cracking and subsequent failure of soil or rock mass. Existing methods for measuring are mainly designed hard materials come with inherent problems. As such, they continuously being adapted improved by the scientific community. In line this effort, we recently developed two new test application to weak rocks, namely, inner hole fracturing (IHFT) horizontal compression (HCT). study, compared performance these newly three most commonly used...
