MECHANISTIC INSIGHTS INTO COKE SUPPRESSION AND ENHANCED OLEFIN SELECTIVITY IN MIXED METAL OXIDE-MODIFIED SAPO-34 FOR HIGH-PERFORMANCE METHANOL-TO-OLEFINS CATALYSIS

The methanol-to-olefins (MTO) process is a key catalytic route for light olefin production, yet challenges related to catalyst deactivation and coke formation persist.In this study, we investigate the catalytic performance of SAPO-34 (SP) and a modified SAPO-34 catalyst incorporating a mixed metal oxide of indium oxide and cerium oxide (SPM) to enh

High resolution mass spectrometry (HRMS)-based non-target analysis coupled with ion mobility spectrometry (IMS) is gaining momentum due to its ability to provide complementary information which can be useful in the identification of unknown organic chemicals STYLE-PREP SPRAY in support of efforts in unraveling the complexity of the chemical exposom

Engagement represents the commitment and bond between a brand and its customers, and achieving high levels of engagement is now a competitive advantage for companies.Determining the engagement index was a high-cost activity for organizations and consumers in the past decade due to the time and cost of data collection.The massive use of social netwo

The hybrid electromagnetic and elastic foil gas bearing is explored based on the radial basis function (RBF) neural network in this study so as to improve its stabilization in work.The related principles and structure of hybrid electromagnetic and elastic foil gas bearings is introduced firstly.Then, the proportional, integral, Ornithine and deriva
