2-butoxyethanol as a Draw Solution for Forward Osmotic Application

Sano K., Ide T., Imada T., Toshiba Corporation, JP

As a draw solution, 2-butoxyethanol (2BE) was examined for forward osmotic application such as power generation and desalination. As forward osmosis experiments, simple hand made cell with a membrane of 5mm in diameter. Under stirring [...]

Modeling of spontaneous phase separation in nanomaterials and confined systems with electron correlations

Kocharian A.N., Fang Kun, Fernando G.W., Balatsky A., California State University Los Angeles, US

The modeled of many body physics and possible spontaneous phase separation instabilities in various two-dimensional square and honeycomb structures (generated by periodically repeated Betts lattices) provide an ideal playground for understanding of various competing phases [...]

Biomimetic Polyurethanes for Regenerative Medicine

Ciardelli G., Sartori S., Serafini P., Boffito M., Caporale A., Silvestri A., Bernardi E., Boccafoschi F., Politecnico di Torino, IT

Degradable linear polyurethanes from non toxic building blocks were prepared. Bioactive peptides were incorporated in polyurethane chains, in order to create a synthetic equivalent of the Extracellular Matrix, able to mimic natural tissue. Both cell [...]

Numerical Simulation of Polymer Phase Separation on a Patterned Substrate with Nano Features

Shang Y., Wei M., Kazmer D., Mead J., Barry C., University of Massachusetts-Lowell, US

Phase separation of an asymmetric immiscible binary polymer system in an elastic field with the existence of a heterogeneously functionalized substrate surface was numerically studied in 2D and 3D. An unconditionally stable method for time [...]

Kinetics of Microdomain Structures in Multi-Phase Polymer-Liquid Crystalline Materials

Das S.K., Rey A.D., McGill University, CA

A mesoscopic kinetic model for phase separation in the presence of liquid crystalline order has been formulated, and solved using high performance numerical methods. The thermodynamic phase diagram on temperature-polymer concentration plane indicates the presence [...]
