Oral films (OFs) continue to attract attention as drug delivery systems, particularly for pedatric and geriatric needs. However, immiscibility between different polymers limits the full potential of OFs from being explored. One example is pullulan (PUL), a novel biopolymer which often has be blended with other reduce cost alter its mechanical properties. In this study, state-of-the-art in fabri...

The health and environmental concerns of the usage non-biodegradable plastics have driven efforts to explore replacing them with renewable polymers. Although starch is a vital polymer, poor water resistivity thermo-mechanical properties limited its applications. Recently, starch/synthetic biodegradable polymer blends captured greater attention replace inert plastic materials; question ‘immiscib...

While methanol and ethanol are macroscopically miscible with water, their mixtures exhibit negative excess entropies of mixing. Despite considerable effort in both experiment and theory, there remains significant disagreement regarding the origin of this effect. Different models for the liquid mixture structure have been proposed to address this behavior, including the enhancement of the water ...

We propose a mean-field theory and dissipative particle dynamics (DPD) simulations of swelling and collapse of a polymer microgel adsorbed at the interface of two immiscible liquids (A and B). The microgel reveals surface activity and lowers A-B interfacial tension. Attempting to occupy as large an interfacial area as possible, the microgel undergoes anisotropic deformation and adopts a flatten...

Abstract Phase equilibria in the TiO 2 –SiO system have been studied experimentally using DTA and SEM/EDX. The thermodynamic parameters for assessed considering new experimental data of present work from literature. Moreover, miscibility liquid Al O 3 –TiO has at 2013 K air shrinkage gap 3.8 mol% demonstrated. obtained literature as well databases binary , systems used to derive description CAL...

Some binary lipid mixtures form coexisting liquid phases when spread at the airrwater interface. This work describes the pressure–composition phase diagrams of binary mixtures of four unsaturated phosphatidylcholines with dihydrocholesterol. These four binary mixtures have critical compositions of approximately fifty mole percent, and average critical exponents of 0.25 "0.07. The data can also ...

Ordered diblock copolymer blends have recently become the subject of tremendous research interest since they can be used to elucidate the intramicrodomain segregation of blocks differing in length, as well as to identify the molecular and blend parameters yielding phase immiscibility. In this work, we explore the influence of molecular architecture on block copolymer blend miscibility by examin...
