Design and fabrication of energy storage systems (ESS) is of great importance to the sustainable development of human society. Great efforts have been made by India to build better energy storage systems. ESS, such as supercapacitors and batteries are the key elements for energy structure evolution. These devices have attracted enormous attention d...

This paper presents the humidity sensing properties of surface-modified polyaniline (PAni). In this study, the impedance response and dielectric properties of pure- and doped-PAni have been investigated as a function of relative humidity (RH%) and frequency. PAni and PAni/Mn composite samples are synthesized by one-step interfacial polymerization p...

Amorphous NiP and NiCrP alloy coatings were prepared on copper substrates by electrodeposition. The thermal stability of the obtained coatings were evaluated by the onset temperature of phase transformation identified with differential scanning calorimetry measurements, and their high temperature oxidation resistances were characterized by the oxid...

Silver nanoparticles (AgNPs) are one of the new cancer treatment tools due to their unique properties that enhance potential therapeutic efficacy. In this study, we describe the extracellular biosynthesis and anticancer activity of AgNPs using the Anabaena flos-aquae biomass extract as reducing agent. The formation of dark-brown AgNO3\documentclass...

Novel Ni–Re super-alloy nanowire type catalyst system is found for hydrogen generation from steam methane reforming. The novel nanowire type catalysts exhibit the super-high catalytic activity for hydrogen generation from steam methane reforming with CO-free in the product at lower reaction temperatures. The Ni–Re alloy nanowire type catalysts are ...

Hydroxyapatite nanoparticles were synthesized using modified sol–gel approach. Its biocompatibility was proved by in vitro experiments with diploid fibroblasts. The experiment showed that the presence of hydroxyapatite in the environment of cells does not reduce their viability. The observed phase transition of hydroxyapatite was explained as order...

Effect of maleic-anhydride-grafted-polypropylene (PP-g-MA) and graphene oxide (GO) addition on the tribological properties of polypropylene (PP) nanocomposites were investigated in this study. Graphene oxides with different levels (0.05 and 0.15 wt%) were used as reinforcing filler for PP nanocomposites. Maleic-anhydride-grafted-polypropylene (3 wt...
