We develop a theory of polymers in a nematic solvent by exploiting an analogy with two-dimensional quantum bosons at zero temperature. We argue that the theory should also describe polymers in an isotropic solvent. The dense phase is analyzed in a Bogoliubovlike approximation, which assumes a broken symmetry in the phase of the boson order parameter. We find a stiffening of the longitudinal flu...

The complexity of sample matrices, coexistence of multiple forms of bioactive phytochemicals, and their interaction of with other cellular components pose a significant challenge for optimized extraction and accurate estimation of bioactive phytochemicals in foods and dietary supplements. This article discusses the significance of optimizing extraction procedures for accurate assay of phytochem...

In this series of lectures, we address mathematical models of materials systems that, in recent decades, have inspired many developments in partial differential equations. From physical point of view, such problems arise in soft condensed matter and are also linked to relevant applications in optics and mechanics. Liquid crystal phases found in organic and synthetic compounds are intermediate b...

PLGA is a biodegradable polymer utilised widely in pharmaceutical research for the encapsulation of a wide range of drugs as nano particulate systems. This study investigates the impact of rotary ball milling on the physical properties of PLGA and its influence on nanoparticle formation prepared using the solvent displacement technique. By applying mechanical stress to the polymer and altering ...

The objective of this study was to evaluate the influence of gelator, vegetable oil, stirring speed, and temperature on the physical properties of obtained organogels. They were prepared under varying independent conditions and applying a fractional experimental design. From there a rheological characterization was developed. The physical characterization also included polarized light microscop...

Meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. The aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. Meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (PEG) 6000. The effect of solubilization by...

     Ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), eudragit RS PO, eudragit RL PO and hydroxypropylmethylcellulose (HPMC) as carriers to improve physicochemical characteristics of ibuprofen. The prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissoluti...

Solution growth using a Si–Cr-based solvent is promising process to produce high quality 4H–SiC single crystal. Computational fluid dynamics simulation an effective method estimate and control the temperature flow in process, although simulations are presently performed physical properties of liquid silicon due lack data for alloy solvent. In present work, density, surface tension, viscosity Si...

Perovskite solar cells (PSCs) are emerging photovoltaic devices with great potential to become a terawatt-scale technology. To develop sustainable end-of-life strategies for PSCs, we performed life cycle assessment on 13 PSC recycling techniques, focusing the recovery of coated glass. We found that ecotoxicity due consumption materials is major contributor environmental impact. All but one tech...
