Synthesizing nanoparticles (NPs) from waste materials offers a sustainable remedy, repurposing abandoned resources into valuable sources. Employing these eco-friendly NPs not only reduces environmental burdens associated with waste disposal, but also enhances resource efficiency and conservation efforts. This study focuses on the synthesis of zinc...

Utilizing agricultural waste for synthesizing nanoparticles (NPs) has increasing importance as it is essential for promoting environmental sustainability. This study focused on biogenic synthesizing ZnO NPs from wood apple outer shell (WA) extract to examine the photocatalytic activity against a widely used industrial dye, IC orange pigment dye (PD...

Green composites offer environmental advantages by incorporating renewable materials, contributing to sustainable practices, and reducing the ecological impact of traditional composites. The current study focuses on the environmentally friendly synthesis of Ag nanoparticles (NPs), ZnO NPs, and Ag-ZnO nanocomposites (NCs) using aqueous extract of wo...

The hollow core, concentric graphitic shells, and large surface area of the carbon nano-onion (CNO) make these carbon nanostructures promising materials for highly efficient catalytic reactions. Doping CNOs with heteroatoms is an effective method of changing their physical and chemical properties. In these cases, the configurations and locations of...

Nanostructuring inorganic solids has been effective as a tool to control the identity of the thermodynamically stable phase under ambient conditions for many systems. In addition, size effects can alter not only the temperature but also the other characteristics of a transformation—such as order, mechanism, and kinetics—which may further be respons...

Designing luminescent materials especially nanomaterials with multifunctional applications is highly challenging and demanding. In this work, we explored pyrochlore La2Hf2O7 nanoparticles (NPs) singly and triply codoped with Eu³⁺, Tb³⁺ and Dy³⁺. Under both ultraviolet and X-ray irradiations, the La2Hf2O7 NPs singly doped with Eu³⁺, Tb³⁺ and Dy³⁺ di...
