چکیده
Any elementary textbook on statistical mechanics will try to convince you that energy is everything w.r.t. phase separation. The goal of this thesis is to show otherwise.

Entropic phase separation in polymer-microemulsion networks.
We study theoretically a model system of a transient network of microemulsion droplets connected by telechelic polymers and explain recent experimental findings. Despite the absence of any specific interactions between either the droplets or polymer chains, we predict that as the number of polymers per drop is increased, the system undergoes a first-order phase separation into a dense, highly c...
متن کاملAn Analyticity Bound for Two-dimensional Ising Model at Low Temperature
We study the coexistence phase in two-dimensional Ising model. Optimizing the cluster expansion technique we are able to prove the phase separation phenomenon, with the Onsager value for the surface tension, in a range > where estimates from above the critical to within 19% and essentially coincides with the entropic bound.
متن کاملCharacterization and optimization of an entropic trap for DNA separation.
Recently, a microfabricated entropic trap array was demonstrated to be useful in separating large (5-200 kbp) DNA molecules efficiently (within approximately 30 min), by dc electrophoresis, on a microchip platform without a sieving matrix. This paper reports further development of the technique, with emphasis on optimizing separation selectivity and resolution. The interaction of DNA molecules ...
متن کاملSupercoiled DNA; plectonemic structure and liquid crystal formation
We have investigated the phase behaviour of pUC18 plasmid solutions with phase separation experiments and polarized light microscopy. Furthermore, the configuration of the superhelix is monitored with small-angle neutron scattering. The phase diagram is interpreted with liquid crystal theory including the effects of charge, orientation entropy, excluded volume, as well as the elastic, entropic ...
متن کاملEntropic splitter for particle separation.
We present a particle separation mechanism which induces the motion of particles of different sizes in opposite directions. The mechanism is based on the combined action of a driving force and an entropic rectification of the Brownian fluctuations caused by the asymmetric form of the channel along which particles proceed. The entropic splitting effect shown could be controlled upon variation of...
