Abstract
The present study concentrated on estimating the thermal conductivity, stability, efficiency, and resistance of a heat pipe for heat exchangers, which were essential for many industrial applications. To achieve this, copolymer of amphiphilic poly (styrene-co-2-Acrylamido-2-methylpropane sulfonic acid) poly (STY-co-AMPS) was synthesized by free radical polymerisation technique. The dispersant were used for homogeneous solution and stabilization of ZnO nanofluids. The effect of dispersant on the thermal conductivity of nanofluids was analysed using a KD2 pro thermal property analyser. There is a significant increase in fluid conductivity had a nonlinear relationship with the volume fraction. The maximum enhancement was observed at an optimized concentration of dispersant at 1.5 vol%. Same time, the influence of dispersant agent on the thermal conductivity of nanofluids were compared with linear polyelectrolytes. Further, the experimental values were compared to the existing classical models based on the reasonable aggrement, the prepared nanofluids were employed as a working medium. The conventional screen mesh heat pipe and the temperature distribution to the thermal resistance of the heat pipe was investigated experimentally. The result shows, optimum concentration of dispersants on nanoparticles exhibits an enhanced heat efficiency as compared with the base fluids. Further, the thermal resistance and temperature distribution show decreased behaviour by increasing the particle volume fraction and dispersant concentration.

Abstract
Compared with traditional liquid electrolytes, solid polymer electrolytes possess higher reliability and safety but lower ionic conductivity, which can be improved by incorporating plasticizers to form gel polymer electrolytes (GPEs).

Abstract
To prolong the duration of polymer erosion over existing approaches for sustained local drug delivery, we investigated a new bioerodible system based on hydrolytically activated in situ formation of interpolymer complexes in binary blends of high MW poly(vinyl methyl ether-co-maleic anhydride) (PVMMA) and poly(ethylene oxide) (PEO). In an aqueous environment of use, the hydrophobic PVMMA component of the blend undergoes hydrolysis converting the anhydride to free carboxylic acid groups which in turn form in situ intermolecular complexes with the PEO component of the blend. The formation of such hydrogen-bonded complexes with a condensed structure at the blend surface helps to retard the further progression of polymer erosion and drug release. The effects of PVMMA/PEO composition on blend morphology, polymer erosion and drug release were evaluated with the aid of fluorescence labeled PVMMA. The results show a decrease in miscibility in PVMMA/PEO blend with increasing PEO content. At low PEO contents (below 40%), the in vitro rate of release of a model drug metronidazole decreases with increasing PEO content, resulting in extended release duration over several days. On the other hand, excessive phase separation at PEO contents above 40% gives rise to higher rate and shorter duration of drug release.
