Description
The first stage of the physics of long, flexible chains was pioneered by eminent scientists such as Debye, Kuhn, Kramers, and Flory, who formulated the basic ideas. In recent years, because of the availability of new experimental and theoretical tools, a second stage of the physics of polymers has evolved. In this book, a noted physicist explains the radical changes that have taken place in this exciting and rapidly developing field.Pierre-Gilles de Gennes points out the three developments that have been essential for recent advances in the study of large-scale conformations and motions of flexible polymers in solutions and melts. They are the advent of neutron-scattering experiments on selectively deuterated molecules; the availability of inelastic scattering of laser light, which allows us to study the cooperative motions of the chains; and the discovery of an important relationship between polymer statistics and critical phenomena, leading to many simple scaling laws.Until now, information relating to these advances has not been readily accessible to physical chemists and polymer scientists because of the difficulties in the new theoretical language that has come into use. Professor de Gennes bridges this gap by presenting scaling concepts in terms that will be understandable to students in chemistry and engineering as well as in physics.

Item arrived on time and was packaged well. The item was exactly as advertised and was amazing value compared to other places. The seller was also incredibly speedy at replying to my enquiries. Although it was not the fault of the seller (the packaging used to send the item was more than sufficient), my figure did have a manufacturing defect (the left hand was broken off). Thankfully superglue put it back in place and no one can tell it was broken.

Item arrived earlier than expected, long delivery time but isn’t necessarily the sellers fault only standard shipping available. Item decently packaged could have been more securely packaged though. Good price compared to other marketplaces and sellers. I cannot comment on the seller’s communication as I did not contact the seller. Overall good experience only complaint would be delivery time but again this isn’t solely the sellers fault.
