Recently, high attention has been paid to template synthesis as a method for obtaining nanostructures with predetermined shapes and sizes. This is an obvious approach, in which the size shape of pores limit geometry formed inside them. As result, completely repeat pores. However, some cases, morphology resulting structures may differ from template, often these differences are not explained. gap...

A series of laboratory investigations are conducted to analyze the effect flocculant type on spatial morphology and microstructural characteristics flocs during flocculation settling tailings. Four types (i.e., ZYZ, JYC-2, ZYD, JYC-1) considered in this study. The fractal internal structures tailings with different settlement heights analyzed by conducting scanning electron microscopy X-ray mic...

Magnesium alloys are an exciting challenge for the biomaterials field given their well-established biodegradability and biocompatibility. However, when exposed to biological fluids, rapid degradation hydrogen release main drawbacks clinical applications. This work aimed investigate influence of current density applied during plasma electrolytic oxidation (PEO) treatment on durability AZ31 magne...

The morphological characteristics of the surface a number films elastomers based on polyurethanimides (PUI) were studied by atomic force microscopy (AFM). Significant differences in morphology PUI found depending composition: from granular with different grain sizes or spongy nano - and submicron pores cavities surface, to spherulitic morphology. It is shown that roughness free surfaces formed ...

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...

considerable information exists in the literature showing that expansive layer silicates are not the only clay minerals present in vertisols. however, the presence of a very high clay content dominated by fine clay, regardless of the clay type, together with the wetting and drying cycle in the soil can also produce a high shrink-swell potential. we studied some vertisols with diverse parent mat...
