- ItemData on single pulse fs laser induced submicron bubbles in the subsurface region of soda-lime glass(Amsterdam [u.a.] : Elsevier, 2020) Lai, Shengying; Ehrhardt, Martin; Lorenz, Pierre; Lu, Jian; Han, Bing; Zimmer, KlausSubmicron bubble formation in the subsurface range of soda-lime glass is investigated. The bubbles are induced by single femtosecond laser pulse irradiation with the wavelength of λ = 775 nm, the pulse duration of tp = 150 fs and the laser beam diameter of ∼12 μm. The data shows the changes of the morphologies of the soda-lime glass after laser irradiation with different pulse energy. Moreover, the data shows the detail of the cross-section view of the bubble during the Focused ion beam (FIB) cutting. It is found that the bubbles can be formed in a rather narrow pulse energy range with the bubbles in the size of 300 nm ∼3 μm which is much smaller than the laser beam diameter. Data presented in this article are related to the research article “Submicron bubbles/voids formation in the subsurface region of soda-lime glass by single pulse fs laser-induced spallation” [1]. © 2020
- ItemEndothelial cell spreading on lipid bilayers with combined integrin and cadherin binding ligands(Amsterdam [u.a.] : Elsevier, 2022) Koçer, Gülistan; Albino, Inês M.C.; Verheijden, Mark L.; Jonkheijm, PascalEndothelial cells play a central role in the vascular system, where their function is tightly regulated by both cell-extracellular matrix (e.g., via integrins) and cell–cell interactions (e.g., via cadherins). In this study, we incorporated cholesterol-modified integrin and N-cadherin peptide binding ligands in fluid supported lipid bilayers. Human umbilical vein endothelial cell adhesion, spreading and vinculin localization in these cells were dependent on ligand density. One composition led to observe a higher extent of cell spreading, where cells exhibited extensive lamellipodia formation and a qualitatively more distinct N-cadherin localization at the cell periphery, which is indicative of N-cadherin clustering and a mimic of cell–cell contact formation. The results can be used to reconstitute the endothelial-pericyte interface on biomedical devices and materials.
