Osswald T., Rudolph N. Polymer Rheology Fundamentals and Applications [PDF] - Все для студента

This allows exploration of many new mechanisms and phenomena, which were previously unachievable with conventional methods such as bulk rheometry tests. For instance, the field of polymer rheology is at a turning point to relate the complex molecular conformations to the nonlinear viscoelasticity of polymeric fluids such as coil—stretch transition, shear thinning, and stress overshoot in startup shear. In addition, nanofluidic devices provided a starting point for manipulating single DNA molecules by applying basic principles of polymer physics, which is highly relevant to numerous processes in biosciences. We particularly focus on advances in the understanding of polymer rheology and identify the emerging research trends and challenges, especially with respect to future applications of nanofluidics in the biomedical field. Understanding the deformation and flow of bio polymers, such as DNA, is a critical challenge in life sciences as well as in polymer science and engineering. In addition, DNA can be prepared in a variety of sizes ranging from just few base pairs to hundreds of thousands of base pairs via gene synthesis and genetic engineering techniques. In contrast to Newtonian fluids, polymeric fluids exhibit complex flow behaviors such as shear thinning, rod climbing, transient stress-overshoot during shear, and flow instabilities, which are related to flow-induced changes in polymer molecular conformations at very high deformation rates.

All Pages Books Journals. Views Total views. In addition, DNA can be prepared in a variety of sizes ranging from just few base pairs to hundreds of fundamebtals of base pairs via gene synthesis and genetic engineering techniques. In the first attempts to visualize the conformation of an individual DNA molecule within the flow field, tiny amounts of fluorescently stained DNA molecules as test chains were dispersed in a solution of unstained DNA molecules background chains.

This technique was originally used to visualize DNA in an elongated conformation after depositing DNA molecules on solid substrates. Structure and Properties of Deforming Polymers 2. You just clipped your first slide. Wang H.
