An extensive analysis of iron-nitrogen-carbon(Fe-N-C)electrocatalysts synthesis and activity is presented concerning synthesis conditions such as initial Fe content,pyrolysis temperature and atmosphere(inert N_(2),reducing NH_(3),oxidizing Cl_(2) and their sequential combinations)and the influence of an external magnetic field on their performance in oxygen reduction reaction(ORR).Thermosetting porous polymers doped with FeCl_(3) were utilized as the Fe-N-C catalysts *** pyrolysis temperature was varied within a 700-900℃*** temperature and atmosphere of pyrolysis strongly affect the porosity and compositi on of the resultant Fe-N-C catalysts,while the in itial amount of Fe precursor shows much weaker *** under NH_(3) yields materials similar to those pyrolyzed under an inert atmosphere(N_(2)).In contrast,pyrolysis under Cl_(2) yields carbon of peculiar character with highly disordered structure and extensive *** application of a static external magnetic field strongly enhances the ORR process(herein studied in an alkaline environment)and the enhancement correlates with the Fe content in the Fe-N-C *** Fe-N-C materials containing ferromagnetic iron phase embedded in N-doped microporous carbon constitute attractive catalysts for magnetic field-aided anion exchange membrane fuel cell technology.

The brain is a high-energy demanding organ, consuming around 20% of the metabolic energy generated. To fulfill this demand, cerebral blood flow(CBF) supplies oxygen and glucose continuously through the intricate network of cerebral blood vessels. Although for many years brain activity and blood flow were conceived as independent processes, mRI-based functional brain imaging demonstrated that there is a coupling between them,

Kriging-boosted CR modeling for prompt infill drilling optimization

Petroleum 2024年第1期10卷 39-48页

作者： Elizaveta S.Gladchenko anna E.Gubanova Denis m.Orlov Dmitry A.Koroteev Skolkovo Institute of Science and Technology Russian Federation Digital Petroleum LLC Russian Federation

The capacitance-resistance model(CRm) has been a useful physics-based tool for obtaining production forecasts for decades. However, the model's limitations make it difficult to work with real field cases,where a lot of various events happen. Such events often include new well commissioning(NWC). We introduce a workflow that combines CRm concepts and kriging into a single tool to handle these types of events during history matching. moreover, it can be used for selecting a new well placement during infill drilling. To make the workflow even more versatile, an improved version of CRm was used. It takes into account wells shut-ins and performed workovers by additional adjustment of the model coefficients. By preliminary re-weighing and interpolating these coefficients using kriging, the coefficients for potential wells can be determined. The approach was validated using both synthetic and real datasets, from which the cases of putting new wells into operation were selected. The workflow allows a fast assessment of future well performance with a minimal set of reservoir data. This way, a lot of well placement scenarios can be considered, and the best ones could be chosen for more detailed studies.
