Organic-inorganic composite materials have attracted great attention because of their potential to combine the features of organic materials with those of inorganic materials. Particularly organic-metal composite such as polymer-silver are promising functional materials in areas ranging from electronic and optical devices to biosensing, antimicrobial agents and catalysis. In general, there are ...

Secondary surface texture is of great significance to morphological variety and further expands the application areas of electrospun nanofibers. This paper presents the possibility of directly electrospinning grooved polystyrene (PS) fibers using both single and binary solvent systems. Solvents were classified as low boiling point solvent (LBPS): dichloromethane (DCM), acetone (ACE), and tetrah...

the vapor extraction (vapex) process, a solvent-based enhanced oil recovery process has been found promising for some heavy oil reservoirs. in this work, the vapex process is studied using a compositional simulator on a number of single-block and multiple block fractured systems. pvt data of one of an iranian heavy oil reservoir are used to tune the equation of state. effects of fracture spacin...

In the previous paper expressions for the partial molar energy and entropy at infinite dilution have been derived based on the inhomogeneous forms of the energy equation and the correlation expansion for the entropy. These expressions are here applied to a series of solutes of varying size in dense hard-sphere and Lennard-Jones solvents, some of which serve as reference systems for comparison w...

Submitted for the MAR13 Meeting of The American Physical Society Processing Solvent Dependent Morphology of Diketopyrrolopyrrole (DPP) based Low Band Gap Polymer and PCBM Blends SUNZIDA FERDOUS, FENG LIU, THOMAS RUSSELL, Polymer Science and Engineering, University of Massachusetts-Amherst — Solution processing of polymer semiconductors is widely used for fabrication of low cost organic solar ce...

Atomistic simulations are used to characterize the molecular dynamics (MD) of alkyl chains with different functionalizations in different water/acetonitrile mixtures (80/20 and 50/50). Starting from fully equilibrated solvent systems (flat density profile for both components), microheterogeneous structuring of the solvent in the chromatographic system is found for both mixtures. Depending on th...

the complexation reactions between mg2+, ca2+, sr2+ and ba2+ metal cations with 15-crown-5 (15c5) were studied in acetonitrile (an)-methanol (meoh) binary mixtures at different temperatures using conductometric method. 15c54 forms 1:1 complexes with mg2+, ca2+ and sr2+ cations in solutions. the ma2+ cation forms a 2:1 complex (ratio of lighand to cation) in solutions. a linear relation was obse...
