An Investigation into the Larvicidal Activity of Biologically Synthesized Silver and Copper Oxide Nanoparticles Against Mosquito Larvae

“…X-ray diffraction (XRD) analysis was conducted to ascertain the crystal structure and phase purity of the nanoparticles. [40,46,47,48] The XRD patterns exhibited well-defined peaks corresponding to specific crystal planes, facilitating the determination of average crystallite size through the utilization of the Debye-Scherrer equation. [40,46,47] Furthermore, the morphology and size distribution of the nanoparticles were investigated utilizing field-emission scanning electron microscopy (FE-SEM).…”

“…[40,46,47,48] The XRD patterns exhibited well-defined peaks corresponding to specific crystal planes, facilitating the determination of average crystallite size through the utilization of the Debye-Scherrer equation. [40,46,47] Furthermore, the morphology and size distribution of the nanoparticles were investigated utilizing field-emission scanning electron microscopy (FE-SEM). Detailed images acquired from FE-SEM imaging displayed well-defined nanostructures with uniform distribution, while statistical analysis of multiple images enabled the determination of average particle size and size distribution of the CuO (18.28 nm) and silver nanoparticles (38.79 nm) also, it has similar to the DLS particle size distribution values.…”

First principle study of scandium-based novel ternary half Heusler ScXGe (X = Mn and Fe) alloys: insight into the spin-polarized structural, electronic, and magnetic properties

“…Recent research reports have also revealed a multitude of physical phenomena associated with these Heusler alloys, including ferroelectricity, ferromagnetism, and ferroelasticity, attributed largely to their multifunctional properties. As a result, these alloys are continually drawing signicant interest in a wide range of elds, including spintronics, 3,4 optoelectronics (such as sensors, magnetoresistors, photovoltaic detectors, and light-emitting diodes), thermoelectronics, 5,6 shape memory applications, 2,7 piezoelectric semiconductors, 3,8 topological insulators, 4,9 and superconductivity. 10,11 Additionally, they offer distinct advantages over conventional electronic devices based on standard semiconductors, owing to the added spin degree of freedom, resulting in benets such as enhanced data processing speed, increased integration densities, and reduced power consumption.…”

Strontium peroxide as a potential photocatalyst: rapid degradation of organic and pharmaceutical pollutants

“…To overcome these limitations, metal peroxides have been developed to get sustainable slow-release of hydrogen peroxide as well as highly stable photoactive material. 23 More importantly, solid peroxides can supply H 2 O 2 in the aqueous environment for an extended time and serve as a rich source of H 2 O 2 generated under in situ conditions. In recent years, ZnO 2 , 24,25 MgO 2 26,27 and CaO 2 28,29 are studied well in the scientific world.…”
