To clarify the reservoir characteristics of laminated shale, occurrence mechanism shale oil and its influencing factors in Gulong Sag, northern Songliao Basin, are studied to better guide exploration development there. First, X-ray diffraction (XRD) field-emission scanning electron microscopy (FE-SEM) used characterize pore types, geneses volume study area. Second, organic matter samples is ext...

Plasmonic systems based on metal nanoparticles on a metal film have generated great interest for surface-enhanced Raman spectroscopy (SERS) chemical sensors. In this study, we describe the fabrication of ultrasensitive SERS substrates based on high-density gold nanostar assemblies on silver films with tailored surface plasmons, where multiple field enhancements from particle-film and interparti...

To evaluate the effects of quartz precipitation on abundance and preservation organic matter pores in marine shale reservoirs, type authigenic source silica, as well corresponding relation Lower Cambrian Shuijingtuo Formation South China were investigated. Quartz occurs four different types: detrital quartz, replacement biosiliceous debris, euhedral filled interparticle pores, microquartz dispe...

Shallow-buried fluvial mudstones are of great significance as potential top seals for natural gas accumulations in the Zhanhua depression. Four samples were chosen to represent range fine-grained microfacies, from clay-rich silt-rich cemented, and mercury injection capillary pressure (MICP) porosimetry is combined with Scanning Electron Microscopy (SEM) characterize microstructure pore systems ...

Metal–organic frameworks (MOFs), assemblies comprised of metal nodes and organic ligands, have captured the interest scientists during past two decades. The flexible approaches developed for custom design framework structures intriguing pore-containing environments formed at molecular or atomic level elevated in MOFs to a that is far beyond those traditional porous solids (e.g., zeolites, activ...

This study is predominantly about the differences in shale pore structure and controlling factors of gas content between Lower Silurian Cambrian from upper Yangtze plate, which are great significance to occurrence mechanism gas. The field emission scanning electron microscopy combined with Particles (Pores) Cracks Analysis System software, CO2/N2 adsorption high-pressure mercury injection poros...

Fabrication of tunable fine textures on solid metal surfaces often demands sophisticated reaction/processing systems. By exploiting in situ polymerization and self-assembly inorganic adducts derived from liquid metals (the so-called HetMet reaction) with concomitant solidification, films texture are readily fabricated. Serving as a natural dimensional confinement, interparticle pores capillary-...

INTRODUCTION Achieving spatially uniform and hierarchically structured microstructures during the shape-forming of colloidal ceramics depends largely on (t) the magnitude of the effective stresses (i.e., stresses that are supported by the particulate network) and (ii) plastic properties, which in turn are significantly altered by processing parameters affecting interparticle friction and adhesi...

we report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (mtu) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (au-nps). this thiol-containing molecule exhibits intriguing affinity with au-nps. the reactivity involves the displacement of the citrate shell by the thiolate shell followed ...

Abstract In this paper, the pore structure characteristics of shales and its controlling factors were analyzed by means total organic carbon (TOC) analysis, X-ray diffraction (XRD) field emission scanning electron microscopy (FE-SEM) low-pressure N 2 adsorption (LPNA) analysis. Based on grey relational parameters discussed. The results showed that TOC contents range from 2.98 to 4.97%, main min...
