Based on a previously developed polyamide proton conductive macromolecule, the nano-scale structure of the self-assembled proton conductive channels (PCCs) is adjusted via enlarging the nano-scale pore size within the macromolecules. Hyperbranched polyamide macromolecules with different size are synthesized from different monomers to tune the nano-scale pore size within the macromolecules, and ...

Nanofiber mats of polyether sulfone/nano hydroxyapatite (PES/nHA) were prepared by electrospinning technique. The fabricated composites were characterized using FTIR, XRD and SEM. The composite nanofiber mats were subjected to in vitro biological studies namely bioactivity, haemocompatibility and cytocompatibility. The XRD analysis showed an increase in the amorphous nature of the composite wit...

The movement of biological fluids in the human body is a premium field interest to overcome growing biomedical challenges. Blood behavior shows different capillaries, veins, and arteries during circulation. In this paper, new mathematical relation for nano-layer flows with effect TiO2 Ag hybrid nanoparticles was developed. Further, we explain engineering phenomena role blood vessel system. impr...

In this work, we investigate the use of a new low-cost gas sensor based on porous silicon to detect low concentration NO2 at room temperature. focused sensing properties two different types (PS) prepared by simple chemical method namely nano-porous (nano-PS) and macro-porous (macro-PS). The sensors are characterized pores size, thicknesses porosity. Electronic synthesized structures were studie...

The aim of this paper is to investigate adhesion property between nano-layered filler and the polymer matrix using a combination of experimental and micromechanical models as well as the changes in yield strength and stiffness of a layered silicate-filled epoxy nanocomposite. The results indicate that addition of intercalated layered silicate particles increased Young’s modulus and yield streng...

Li₄Ti₅O₁₂/activated carbon hybrid supercapacitor can combine the advantages of both lithium-ion battery and supercapacitor, which may meet the requirements for developing high-performance hybrid electric vehicles. Here we proposed a novel "core-shell" porous graphitic carbon (PGC) to replace conventional activated carbon for achieving excellent cell performance. In this PGC structure made from ...

We report the design and synthesis of a novel kind of organic-inorganic hybrid material via the incorporation of europium (III) β-diketonate complexes (Eu(TTA)3, TTA = 2-thenoyltrifluoroacetone) into one-dimensional (1D) porous boron nitride (BN) microfibers. The developed Eu(TTA)3@BN hybrid composites with typical 1D fibrous morphology exhibit bright visible red-light emission on UV illuminati...

Oil palm ash (OPA), a bio-agricultural waste from oil palm mills, was subjected to high-energy ball milling for 30 h and was converted into a nano-structured material. The nano-structured OPA was characterized for its particle size and crystallinity index by using Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) analysis. The crystallite size obtained from TEM and XRD was foun...
