Formation mechanism and structural characteristic of pore-networks in shale kerogen during in-situ conversion process

In recent years there has been increasing interest concerning the synthesis of hollow materials in nanometer to micrometer dimensions. Hollow hydroxyapatite(HAP) microspheres with pores on their surfaces were prepared by a Li-Ca-B glass in situ immersion conversion process in an aqueous phosphate solution at 37°C. The chemical reaction ability of the Li-Ca-B glass was studied by immersing the glass in SBF solution, and the phases of the reaction product were identified by the XRD method. The morphology, composition, phases and thermal property of the hollow HAP microspheres were investigated using by chemical analysis, SEM ,and XRD . The microphere wall consisted of calcium deficient hydroxyapatite (CDHAP) crystals only. Furthermore, the formation mechanism of the hollow HAP microsphere was also discussed.

In Situ Sensors

Conversion of CO2 into fuel is an interesting and promising field. However, the conversion yield is hard to measure during the conversion process. Here, we have developed two techniques to measure the amount of CO2 while the reaction is taking place. First method is colorimetry, where a chemical is added to the solution, and it changes color depending on the resulting product. The second method is the atomization of the resulting solution. Thereafter, the results were measured by a gas sensor. The prepared sensors are cost effective and portable to use.
