All these methods confirmed the existence of thermal excitations in the plane of the surface of the phospholipid membranes or the corresponding structures, respectively. Also, these measurements revealed a temperature dependence of these excitations. These excitations are associated with 100 nm in-plane correlations around physiological temperatures and of 75 nm at 16∘C. A single excitation has an energy around the μeV-regime. A temperature series revealed a high abundance at physiological temperatures and pronounced long-range in-plane structures, which are strongly suppressed at temperatures below 20∘C. From the length-scales and energy transfers involved we surmise that these excitations may play a role in several functions of the cell membranes such as stability and energy dissipation along the membrane. From a fundamental point of view, the observed behavior of those excitations is congruent with that of a quasi-particle (surface mode phonon, smomon) that exists in the plane of phospholipid membranes.}, cin = {JCNS-1 / JCNS-FRM-II}, ddc = {530}, cid = {I:(DE-Juel1)JCNS-1-20110106 / I:(DE-Juel1)JCNS-FRM-II-20110218}, pnm = {6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623) / 6215 - Soft Matter, Health and Life Sciences (POF3-621) / 551 - Functional Macromolecules and Complexes (POF3-551)}, pid = {G:(DE-HGF)POF3-6G4 / G:(DE-HGF)POF3-6215 / G:(DE-HGF)POF3-551}, experiment = {EXP:(DE-MLZ)KWS1-20140101}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:31310735}, UT = {WOS:000498339400002}, doi = {10.1016/j.chemphyslip.2019.104788}, url = {https://juser.fz-juelich.de/record/863827}, }
