Facile development of carbon nanotube (CNT)-based flexible thermoelectric materials for energy-harvesting applications.

In this study, we investigate the thermoelectric properties of functionalized multi-walled carbon nanotubes (F-MWCNTs) dispersed over a flexible substrate through a facile vacuum filtration route. To improve their interfacial adhesion and dispersion, F-MWCNTs underwent hot-pressing. The heat-treatment has improved the nanotubes' connections and subsequently reduced porosity as well, which results in an increasing electrical conductivity upon increasing temperature of hot-pressing.

Synthesis and Characterization of Cobalt-Doped Ferrites for Biomedical Applications.

Novel materials for biomedical applications are in critical need of time. In the present work, the antibacterial properties of Co Ni Mg FeO nanoparticles (NPs) are assessed by the disc diffusion method for the common pathogen, that is, Gram-negative ( and ) and Gram-positive () bacteria. Overnight grown bacterial cultures were individually lawn-cultured on nutrient agar plates.

Enhanced Ferroelectric and Dielectric Properties of Niobium-Doped Lead-Free Piezoceramics.

Lead-free ceramics are promising candidates for replacing lead-based piezoelectric materials such as lead-zirconate-titanate (PZT) if they can compete in dielectric and ferroelectric characteristics. In this work, for lead-free piezoelectric ceramic, 0.74(BiNaTiO)-0.

Shape Memory Hybrid Composites.

Smart structures can help to resolve many issues related to conventional materials that are being used in different industries. Shape memory alloys (SMAs) are smart materials with better actuation response, vibration damping characteristics, and large strain recovery, making them good candidates due to their high strength and corrosion resistance for various engineering applications. The performance of fiber-reinforced polymer (FRP) composite materials that are replacing many conventional materials due to their good strength, stiffness, and lightweight potential especially in fuel-consuming industries such as aerospace and automotive, can further be improved by impregnation with SMAs.
