The results clarify the properties of the phospholipid layers at different values of the applied field and they help to characterize three consecutive phase transitions. Interactions with gramicidin peptides are quantitative and selective. A general one and two capacitor model has been developed and applied which takes account of frequency dispersion in the capacitor and interfacial problems between the capacitor and the solution resistance.<\/p>","protected":false},"excerpt":{"rendered":"<p>Lecturer ANDREW NELSONUniversity of Leeds, Leeds, Great Britain Date and time Thursday, January 9, 2003 at 11 a.m. Location Lecture Hall,\u2026<\/p>","protected":false},"author":4,"featured_media":2512,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"iawp_total_views":2,"footnotes":""},"categories":[15],"tags":[],"class_list":["post-2466","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-seminari"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
