The effect of the silane concentration and temperature on the course of the reaction was considered. Experimental results indicate that the silanization reaction is more effective in the case of Silsep, favoring both the reaction of silane molecules with the filler surface and the reaction between neighboring silane molecules. This different behavior is attributed to structural factors, moisture, and number of acid centers on silica surface. Environmental scanning electron microscopy (ESEM) was used to deposit micrometric water drops on the surface of these samples and to evaluate the proportion and distribution of the organophylization process.","is_dataset_classified":null,"base_score":3.5263605246161616,"endowment":3.5263605246161616,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"16457834","pmcid":null,"openalex_id":"https://openalex.org/W2043511558","authors":[],"funders":[],"total_grants":0,"fwci":0.8864,"citation_percentile":0.70863855,"influential_citations":0,"citation_trend":[{"year":2012,"count":3},{"year":2013,"count":2},{"year":2015,"count":4},{"year":2016,"count":2},{"year":2017,"count":3},{"year":2018,"count":1},{"year":2019,"count":2},{"year":2020,"count":1},{"year":2021,"count":2},{"year":2022,"count":1},{"year":2023,"count":1},{"year":2025,"count":1},{"year":2026,"count":2}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0021979705013032?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0021979705013032?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.jcis.2005.12.056","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/16457834","host_type":"repository"},{"url":"http://hdl.handle.net/10261/34238","host_type":"repository"}],"fields_of_study":["Advanced NMR Techniques and Applications","Chemical Synthesis and Characterization","Clay minerals and soil interactions"],"mesh_terms":[],"keywords":["Silanization","Silane","Sepiolite","Chemistry","Reactivity (psychology)","Chemical engineering","Scanning electron microscope","Molecule","Environmental scanning electron microscope","Reaction mechanism","Materials science","Inorganic chemistry","Organic chemistry","Catalysis","Composite material"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-06T20:05:42.666756Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
