Abstract Water is polluted by various harmful toxic chemical substances, precisely heavy metals, dyes, and pathogens, which have a disastrous effect on the ecological balance of human as well as animal life. Therefore, there is an urgent need for new technologies to remove these noxious pollutants from water/wastewater. Adsorption is one of the predominant method among all the reported techniques for the removal of heavy metals. Nano technological applications in this direction, i.e. development...

Abstract Bimetallic Fe(III) doped ZnO (FZO) nanoparticles (NPs) were synthesized to be utilized as heterogeneous nano-catalysts. The synthesized NPs were characterized using various physical techniques. Average particle size and surface area of NPs were found to be 76.24 ± 17 nm, and 12.39 m2 g−1, respectively. Designed nano-catalyst was found to be soft ferromagnetic in nature, with 1.32 ± 0.2 emu g−1 magnetization and 75.52 ± 2 Oe coercivity. FZO NPs indicated efficient transesterification rea...

Abstract Hydroxyapatite (HAp) has substantial bioactivity, biocompatibility, osteoconductivity, and facilitates direct bonding to the natural bone. These excellent properties make HAp a utilitarian material for various biomedical applications such as bone tissue engineering, biologicals delivery systems, bioactive coatings, etc. However, lower mechanical strength, slower degradation rate, lower osteoinduction, relative lower drug loading capacity, and absence of target efficiency as a delivery s...

Abstract Recent era demands the antibacterial agents to reduce the side effects and other associated problems with conventional antibiotics. Here, we report the synthesis of Al doped ZnO (AZO) via precipitation method and its utilization as nanoantibiotic. ZnO nanoparticles own decent bactericidal activity against a broad spectrum of bacterial species. However, the bactericidal efficiency of ZnO remains a major challenge. Therefore, to enhance the antibacterial efficiency of ZnO, Al was doped in...

Abstract The use of gadolinium orthoferrite for biomedical application like as contrast agents for magnetic resonance imaging (MRI) has been found to be very promising due to its fascinating properties. The present study focuses on the determination of the effect of the gadolinium concentration in the formation biphasic α-Fe2O3-GdFeO3 for hyperthermia applications. An in-situ sol-gel technique was adopted for the synthesis of biphasic orthoferrites with four different gadolinium concentrations. ...

Nanoantibiotics are the new class of antibacterial agents that can be an alternative to the conventional antibiotics, which are expensive and require lengthy synthesis procedures. In view of such importance of nanoantibiotics, in the present study, we have systematically designed Al doped ZnO (AZO) via a co-precipitation method. ZnO nanoparticles own decent bactericidal activity against clinically isolated bacterial species, however, its bactericidal concentrations are compromised. To enhance th...

Abstract World’s energy needs are majorly dependent on the fossil fuels, including petrochemical sources and coal. The alternate of these fuels include hydro and nuclear powers. However, all these resources are finite and current rate of consumption indicates the shortening of the fuels and energy in the near future. Diesel plays a remarkable role in the economy of the developing and developed countries in industry and other sectors being a basic fuel used in transportation. The increasing deman...
