Summary: Efficient use of energy is crucial for reducing energy costs and environmental pollution. The study investigates the effects of panel radiator type, operating temperature, and flow rate on heat transfer coefficient and entropy generation. The findings indicate that the most important parameter for total heat transfer coefficient is the volumetric flow rate, while the number of panels is the most effective parameter for entropy generation.

Summary: The aim of this study was to develop a novel amikacin (AMI) delivery system with prolonged release. Composite electrospun nanofibers of PLA supplemented with AMI-loaded Si nanoparticles of different morphology were used. The physical properties of the resultant materials were characterized and the AMI content in the release study was determined. The results showed that the silica nanoparticles had a significant effect on the hydrophilic properties of the nanofiber surfaces and the AMI-loaded nanofibers exhibited enhanced antibacterial properties.

Summary: This study optimized the synthesis parameters of nanosized zinc oxide using the electrospinning technique. The effects of applied voltage, tip-to-collector distance, and annealing temperature on the particle size of zinc oxide were investigated. The results suggest that precise control of size and morphology of nanosized zinc oxide can be achieved by varying electrospinning conditions, precursor solution concentration, and sintering temperature.

Summary: This study explores the morphology and in vitro response of electroconductive composite nanofibers for biomedical use. The composite nanofibers are prepared by blending piezoelectric polymer PVDF-TrFE with electroconductive materials such as CuO, P3HT, CuPc, and MB, resulting in unique combinations of electrical conductivity, biocompatibility, and other desirable properties. SEM analysis reveals differences in fiber size as a function of the electroconductive phase used, and electrical measurements show that MB has the highest charge transport ability. In vitro assays demonstrate a tunable response of fibers, with fibroblast cells showing a preferential interaction with P3HT-loaded fibers, making them suitable for biomedical applications.
