SCMF – Single Chain Mean Field Theory

Basics
The Single Chain Mean Field (SCMF) theory was originally proposed by Ben-Shaul, Szleifer and Gelbart [zotpressInText item=”{QBZPNNQN},{RXXJ3MHB}”] to describe micellization of block copolymers. This method has further been developed to describe the structure of phospholipid membranes at the molecular level[zotpressInText item=”{4KUHSU4T},{QE3GFT2S}”]. SCMF is one of the theoretical tools exploited in the Molecular Simulation group in Tarragona.
 The SCMF theory describes a […]
