It is assumed that the dynamics of these bub-bles depends on changes in the geometry of the flow and the excitation of sound vibra-tions in the flow. Particular attention is paid to the process of changing the density of a liquid due to the effect of an internal airlift in a liquid dispersed medium. Mechanically induced kinetic changes in macromolecules (destruction and synthesis of colloidal chains) can occur when bubbles collapse. These features can be used in oil processing and well logging to assess oil saturation of reservoirs.","PeriodicalId":228648,"journal":{"name":"ADVANCES IN APPLIED PHYSICS","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123364188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ag clusters are generated in the cavity of Ag-type zeolite-A, X, and Y heating in atmosphere. The Ag clusters in the zeolite cavity break down when cooled to room temperature after heating in atmosphere. Results of this study suggest that collapsing Ag cluster plays an important role in the generation of strong PL bands and that Ag clusters might not be a direct species of PL. Results also show that the local sites of Ag ions differ slightly from the unheated species induced by the formation and destruction of Ag clusters.","PeriodicalId":228648,"journal":{"name":"ADVANCES IN APPLIED PHYSICS","volume":"371 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132706103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
