We have studied phase synchronization between two identical Rössler oscillators connected in the drive-response configuration by a single phase signal. Before the transition to phase synchronization, the distribution of the time interval between consecutive 2pi jumps shows several sharp peaks. With a strong phase signal coupling, the n:m phase synchronization between the oscillators can be achi...

The properties of interfaces are discussed between coexisting phases in phase separated aqueous solutions of polymers. Such interfaces are found in food, where protein-rich and polysaccharide-rich phases coexist. Three aspects of such interfaces are highlighted: the interfacial profiles in terms of polymer composition and polymer concentration, the curvature dependence of the interfacial tensio...

Aqueous biphasic systems (ABS) provide an alternative and efficient approach for the extraction, recovery and purification of biomolecules through their partitioning between two liquid aqueous phases. In this work, the ability of hydrophilic phosphonium-based ionic liquids (ILs) to form ABS with aqueous K(3)PO(4) solutions was evaluated for the first time. Ternary phase diagrams, and respective...

Secondary organic aerosol (SOA) comprises a significant portion of atmospheric particular matter. The impact of particular matter on both human health and global climate has long been recognized. Despite its importance, there are still many unanswered questions regarding the formation and evolution of SOA in the atmosphere. This study uses a modeling approach to understand the preferred partiti...

In this research nano particles of bismuth ferrite (BiFeO3) were synthesized by sol-gel auto-combustion route. The effect of water and ethylene glycol solvents were studied on phase constituents, magnetic properties and microstructure of the bismuth ferrite by X-ray diffraction (XRD), scanning electron microscope (SEM) and vibration sample magnetometer (VSM) techniques. XRD resul...

The viscoelastic properties of adsorbed protein layer in food emulsions and foams are important in providing stability to such systems. Linear stability analysis for a protein stabilized aqueous film sandwiched between two semi-infinite oil phases with a viscoelastic liquid-liquid interface is presented. The interfacial dilatational and shear viscoelastic properties are described by Maxwell mod...

Geologic sequestration in depleted oil reservoirs, saline aquifers, etc. has been proposed as an effective way to stabilize the concentration of CO2 in the atmosphere and thus mitigate its effect on global climate change. We have developed a massively parallel 3-D reservoir simulator PFLOTRAN for modeling supercritical CO2 sequestration in geologic formations based on continuum scale mass and e...
