Electroresponsive Acrylic Gels
This articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under DC electric field and b) a physico - mathematical description.a) Gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at pH 12 by teteramethylethylene diamine. Equlibrium properties of the resulting gels rods (water content,...
متن کاملThermoresponsive Gels
Thermoresponsive gelling materials constructed from natural and synthetic polymers can be used to provide triggered action and therefore customised products such as drug delivery and regenerative medicine types as well as for other industries. Some materials give Arrhenius-type viscosity changes based on coil to globule transitions. Others produce more counterintuitive responses to temperature ...
متن کاملUbiquitous Verification of Ubiquitous Systems
Ubiquitous embedded computing systems expected to reliably perform one or more relevant tasks need design and verification methods currently not available. New envisioned applications and trends in system design increase this need. Several of these trends, e.g. function integration, concurrency, energy awareness, networking and their consequences for verification are considered in this article....
متن کاملActin gels
Solutions and gels of the filamentous protein F-actin have not only been the subject of numerous recent biophysical studies, but have also proven to be quite fruitful model systems for fundamental polymer science. They are particularly good models of ‘semiflexible’ polymers, because they have an enormous ratio of persistence length to molecular diameter with characteristic mesh sizes of the ord...
متن کاملA model of ideal elastomeric gels for polyelectrolyte gels.
The concept of the ideal elastomeric gel is extended to polyelectrolyte gels and verified using a polyacrylamide-co-acrylic acid hydrogel as a model material system. A comparison between mixing and ion osmosis shows that the mixing osmosis is larger than the ion osmosis for small swelling ratios, while the ion osmosis dominates for large swelling ratios. We show further that the non-Gaussian ch...
