HEMA hydrogels are hydrophobic biocompatible hydrogel with high mechanical and viscoelastic properties, which are widely used in biomedical application including drug delivery systems. The mechanical properties and permeability of these hydrogels can be tu ...
Dendronized polymers consist of an elastic backbone with a set of iterated branch structures (dendrimers) attached at every base point of the backbone. The conformations of such molecules depend on the elastic deformation of the backbone and the branches, ...
Polymer-protein conjugates generated from side chain functional synthetic polymers are attractive because they can be easily further modified with, for example, labeling groups or targeting ligands. The residue specific modification of proteins with side c ...
Hydrogels are cross-linked, water-swollen polymer networks that are widely used as a biomaterial. Because of high amount of water, they are mechanically poor and soft. This aspect limits their applications. The suitability of hydrogels as biomedical materi ...
Grid turbulence of polyethylene oxide (PEO) solutions (Polyox WSR-301 in H2O) has been investigated experimentally for three concentrations of 25, 50 and 100 weight ppm, at a turbulence Reynolds number based on a Taylor microscale of Re-lambda approximate ...
Polyelectrolytes (PEL) and PEL complexes formed by electrostatic interaction are recognized as compounds with a remarkable potential for a wide field of applications. However, comprehensive knowledge about electrostatic and structural influences on the pol ...
PEGDA hydrogels copolymerized with NVP using free-radical photopolymerization are used in biomedical applications. These networks consist of a poly(acrylate-co-vinyl pyrrolidone) backbone crosslinked with PEG chains whose crosslink density is dependent on ...
The goal of this project is determination of viscoelastic properties (creep, relaxation, and dissipation) of biodegradable HEMA-based (hydroxyethyl methacrylate) hydrogels. The viscoelastic characterization will be done under compression as well as shear ( ...
The equilibrium dynamics of a spherical particle immersed in a complex Maxwell fluid is analyzed in terms of velocity autocorrelation function (VACF), mean-square displacement (MSD), and power spectral density (PSD). We elucidate the role of hydrodynamic m ...
Aliphatic polyesters receive increasing attention over the last years driven by their application as biodegradable substitutes for conventional commodity thermoplastics and applications in the biomedical field, where amongst the family of biodegradable pol ...
