During wound healing and in a variety of fibrocontractive diseases, fibroblasts differentiate into contractile myofibroblasts by acquiring stress fibers and by expressing α-smooth muscle actin (α-SMA). Myofibroblasts of wound granulation tissue, in contras ...
We present a detailed study of proton dynamics in the hydrogen-bonded superprotonic conductor CsHSO(4) from first-principles molecular dynamics simulations, isolating the subtle interplay between the dynamics of the O-H chemical bonds, the O center dot cen ...
In this thesis, we present Scanning Tunneling Microscopy investigations of two-dimensional supramolecular architectures and metallic nanostructures on pre-structured surfaces. We studied different self-assembled supramolecular architectures formed by linea ...
Hybrid solids, made of chem. dissimilar components, have drawn much interest in advanced materials synthesis due to their structural versatility and multifunctional properties. For example, metal-org. frameworks (MOFs) have been extensively explored for th ...
A phenomenological Landau-theory model, where a crystal on cooling from a state with polar symmetry exhibits a maximum of dielectric permittivity and polarization-field hysteresis loops, is offered. The model is equivalent to that of a true ferroelectric i ...
Upon submonolayer deposition of Azure A molecules onto reconstructed Au(1 1 1), two-dimensional quasi-rectangular islands are observed by low-temperature scanning tunneling microscopy. Strikingly, the 22 x root 3 reconstruction with alternating hexagonal c ...
We explored the effects of addition of the nonionic surfactant Triton X-100 on the stability of aggregates of poly(ethylene glycol-bl-propylene sulfide) di- and triblock copolymers. Fluorescence spectra of pyrene, used as a probe molecule, elucidated the v ...
Room temperature ionic liquids comprise an unique class of solvent composed of organic and inorganic-based ions that are molten under ambient conditions. They are characterised by high solvent polarity and low vapour pressure, and can be tailored to have s ...
A new method is presented for recording excitation spectra of molecules embedded in helium nanodroplets. The method relies on the complete evaporation of the droplets following excitation of an dissolved molecule and the subsequent detection of the remaini ...
We have previously shown that the switch from N-cadherin to OB-cadherin expression increases intercellular adhesion between fibroblasts during their transition from a migratory to a fibrogenic phenotype. Using atomic force microscopy we here show that part ...
