Dyes are priority pollutants, commonly found at significant concentrations in textile effluents. The presence of dyes stuffs in wastewater can cause severe problems to aquatic life and human beings. Therefore, the removal of dyes from wastewater is important in order to minimize their hazardous effe...

In recent years, a new group of nanomaterials named nanozymes that exhibit enzyme-mimicking catalytic activity has emerged as a promising alternative to natural enzymes. Nanozymes can address some of the intrinsic limitations of natural enzymes such as high cost, low stability, difficulty in storage...

To improve the thermal conductivity of epoxy resins without losing the insulation, epoxy/silicon nitride (Si3N4) nanowire composites were produced. β-Si3N4 nanowires were synthesized by the carbothermal reduction and nitridation of a homogeneous mixture of silica (SiO2), carbon, and a small amount o...

Abstract We demonstrate a facile efficient way to fabricate activated carbon nanosheets (ACNSs) consisting of hierarchical porous carbon materials. Simply heating banana leaves with K 2 CO 3 produce ACNSs having a unique combination of macro‐, meso‐ and micropores with a high specific surface area o...

Mn3O4 nanoparticles (NPs) were synthesized from the reduction of KMnO4 with glycerol at 80 °C in aqueous media via a gel formation route. In order to investigate the thermal stability and phase transformation, Mn3O4 NPs were subjected to heat treatment from 200 °C to 700 °C. The formation of differe...

In this investigation, undoped BiFeO3, Gd doped Bi0.9Gd0.1FeO3, and Gd-Ti co-doped Bi0.9Gd0.1Fe1-xTixO3 (x = 0.10, 0.20) materials were synthesized to report their multiferroic properties. The structural analysis and phase identification of these multiferroic ceramics were performed using Rietveld r...

Graphene oxide (GO) and reduced graphene oxide (rGO) were synthesized from graphite powder to compare the adsorption capacity of GO and rGO towards a cationic dye-methylene blue (MB). These synthesized nanomaterials were analyzed by Fourier Transform-Infrared Spectroscopy (FTIR), Brunauer-Emmett-Tel...

Industrial effluents contaminated with different types of organic dyes have become a major concern to environmentalists due to the carcinogenic nature of the dyes, which are harmful to human and aquatic life. In recent years, the treatment of contaminated effluents by natural resources has been prop...

Magnetic nanozymes with peroxidase-mimicking activity have been widely investigated for developing molecular biosensors. Herein, we report a starch-assisted method for the synthesis of a novel class of carboxyl group-functionalized iron oxide nanoparticles (C-IONPs). Scanning electron and transmissi...
