An overview of the theoretical/computational methods that allow study thermodynamic stability polymer blends for photovoltaics is provided. After discussing fundamental concepts blend and solubility, including mixing enthalpy Flory–Huggins theory, some experimental approaches to determine interaction parameter in organic photovoltaic (OPV) are briefly discussed, advances modeling based on use a...

The gas separation performance of biopolymers is still scarcely characterized, mostly because their poor thermomechanical properties and high crystallinity which associated to low permeability. In this work we characterize the transport in a poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) random copolymer, that has relatively good mechanical properties, combined with renewable origin, biodegrad...

The surface of monodisperse silica particles synthesized using the Stober process were coated with a thin layer of polystyrene. Surface charge groups were attached by a grafting polymerization of styrene sulfonate. The resulting highly charged monodisperse silica particles self-assemble into crystalline colloidal arrays (CCA) in deionized water. We polymerized hydroxyethyl methacrylate (HEMA) a...

Biologically functional liquid-liquid phase separation of intrinsically disordered proteins (IDPs) is driven by interactions encoded by their amino acid sequences. Little is currently known about the molecular recognition mechanisms for distributing different IDP sequences into various cellular membraneless compartments. Pertinent physics was addressed recently by applying random-phase-approxim...

Equilibrium swelling of 8 wt % suspension waxy (WMS) and normal (NMS) maize, waxy(WRS) normal(NRS) rice when heated to 80 °C at different sucrose concentrations (0–30 %) were characterized. The power reached maximum values 10.5 14.5 concentration 5 10 for NMS WRS respectively, increased with WMS from 11 15.5 decreased NRS 8.2. onset temperature gelatinization all starches whereas enthalpy maize...

We study the aggregation phenomenon in lyotropic chromonic liquid crystals as molecular concentration changes and condensing agents are added into system. Using properties of critical points Oseen-Frank energy a nematic crystal, combined with geometric constraints hexagonal columnar phases, we show that minimizers total topologically equivalent to tori, agreement available experimental evidence...
