The synthesized CONASH was characterized with various microscopic observations...
This paper presents graphite recycling by doping nanosilver for water filtration because of the need for secure water for consumption. It has demonstrated the significance of looking for alternative materials that can filter water independently or in combination with other materials. Adsorbent nanomaterials have unique characteristics as compared to conventional ones due to their...
An innovative strategy to reduce water pollution is adsorption-assisted photocatalysis. A novel mesoporous heterogeneous adsorbent MOF-5-based photocatalysts were successfully synthesized by a green method from plastic waste through a one-step solvothermal process. Additionally, ZnFe2O4 nanocrystals were physically ground with commercial Degussa P25 at room temperature to prepare...
This work represents the shaping of alumina–zinc oxide (AZ) samples with the direct coagulation casting method. The effect of zinc oxide (0, 10, 20, 30, and 40 wt%) and the firing temperatures on the phase composition, microstructure, physical properties, and mechanical properties of the AZ samples were studied. The effect of titanium oxide (2, 5, and 7 wt%) and the firing...
Hydrogels are potential materials in many biomedical applications. A particularly promising application is their use in bone tissue engineering as implants or layers on the surface of titanium alloys. Disadvantage in the use of hydrogels in drug release system is often “burst release” effect what obstructs controlled release of pharmaceutically active agent. This functionality...
There are many great uses for heavy elements that are expanding daily and generating enormous amounts of effluents.

To understand the properties of...
Organic solar cell (OSC) devices suffer from low power conversion efficiency (PCE) due to deep trap states that absorb photogenerated charges, act as recombination centers, and reduce charge collection. To further improve the PCE, an optimized hole transport layer (HTL) must be engineered for efficient hole transport and reduced deep trap states. A hybrid HTL consisting of...
Aluminum is the universal fuel for solid propellants; however, its passive oxide layer could impede the full exploitation of its enthalpy.
