The interfacial water structure, described by the water density, hydrogen bonding, diffusion, distribution of the OH bond and dipole orientations, is strikingly influenced by the surface charge sign and density. We find anomalous electrokinetic effects which are related to the distribution of counterions close to the surface, ion-specific effects and the interfacial water structure. On a negatively charged graphene layer, the attraction of Na+ ions towards the surface enhances the interfacial friction. In contrast, if the surface is positively charged, high surface charge density triggers an anomalous enhancement of electroosmotic flow, accompanied by an abrupt change of the interfacial water structure. At high surface charge densities, the mobility of the interfacial water at the positively charged surfaces is suppressed more strongly compared to the negatively charged surface. Our results reveal new electrokinetic phenomena by the comparison of negatively and positively charged surfaces.","is_dataset_classified":null,"base_score":3.2188758248682006,"endowment":3.2188758248682006,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"26207759","pmcid":null,"openalex_id":"https://openalex.org/W2767824324","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"31500801","title":null},{"funder_name":"National Natural Science Foundation of China","grant_id":"NE810/10","title":null},{"funder_name":"Deutsche Forschungsgemeinschaft","grant_id":"unidentified","title":"unidentified"}],"total_grants":3,"fwci":0.6541,"citation_percentile":0.6581004,"influential_citations":0,"citation_trend":[{"year":2018,"count":1},{"year":2019,"count":2},{"year":2020,"count":3},{"year":2021,"count":5},{"year":2022,"count":4},{"year":2023,"count":5},{"year":2024,"count":2},{"year":2026,"count":2}],"oa_status":"green","license":"Elsevier TDM","oa_locations":[{"url":"https://doi.org/10.17169/refubium-1354","host_type":"repository"},{"url":"https://doi.org/10.17169/refubium-1354","host_type":"repository"},{"url":"https://api.elsevier.com/content/article/PII:S0013468617323824?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0013468617323824?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.electacta.2017.11.031","host_type":"journal"},{"url":"https://refubium.fu-berlin.de/handle/fub188/23568","host_type":"repository"},{"url":"https://refubium.fu-berlin.de/bitstream/fub188/23568/1/Cao_Netz_Electacta_2018.pdf","host_type":""},{"url":"https://dx.doi.org/10.17169/refubium-1354","host_type":""},{"url":"https://dx.doi.org/10.1016/j.electacta.2017.11.031","host_type":""}],"fields_of_study":["Nanopore and Nanochannel Transport Studies","Electrostatics and Colloid Interactions","Geophysical and Geoelectrical Methods","0103 physical sciences","02 engineering and technology","0210 nano-technology","01 natural sciences"],"mesh_terms":[],"keywords":["Electrokinetic phenomena","Chemical physics","Charge density","Surface charge","Molecular dynamics","Ion","Chemistry","Hydrogen bond","Molecule","Counterion","Materials science","Analytical Chemistry (journal)","Computational chemistry","Physical chemistry","Organic chemistry","Hydrophobic surfaces","Electrohydrodynamics","500 Naturwissenschaften und Mathematik::530 Physik::530 Physik","Ion specificity"],"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":"2026-08-18T04:03:49.516470Z","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":[]}
