In the present work, zinc oxide nanoparticles (ZnO-NPs) were synthesized in the presence of poly(ethylene glycol) which is a biocompatible agent in living systems. The sub-chronic effects of ZnO-NPs were investigated based on biochemical parameters and histological changes applied to Rattus norvegicus. The structural, morphology, and size characterization of nanoparticles were studied by applying techniques as XRD, SEM, FTIR, and TEM. 8-week intraperitoneal injection of ZnO-NPs at a dose of 100 mg/kg leads to significant changes in liver enzymes, malondialdehyde (MDA) content, and tissue histopathological changes. The animal group which was treated with 50 mg/kg of ZnO-NPs presented elevated blood urea nitrogen and creatinine levels, but the liver enzymes and liver histopathology were found to be in normal level. The rats exposed to increasing dose of ZnO-NPs (100 mg/kg) showed necrosis of germinal epithelium and sertoli cells in the seminiferous tubules. The current study clearly demonstrated the dose-dependent toxicity of zinc oxide nanoparticles.

“…Many water quality indicators, such as chemical oxygen demand (COD), total organic carbon (TOC), biological oxygen demand (BOD), odor, and bacterial and microbial disinfection, are evaluated using advanced oxidation processes (AOPs) for wastewater treatment . AOPs and hybrid-AOP processes will be considered the next generation of technology in the 21st century because they provide a complete solution in aqueous systems without producing any toxic by-products while also completely mineralizing contaminants into CO 2 and H 2 O or degrading them into some nontoxic forms . In spite of these all process, it fails in tailoring to specific contaminants, which is considered as an issue.…”

In recent years, organic and inorganic contaminants in wastewater (heavy metals, halides, nutrients, dyes, and pathogenrelated water pollution) have become a major global problem. There were initially fewer toxins, but as a result of fast industrialization and other human activities, they have rapidly risen. In addition to producing a host of health problems and organ system failure in people, these toxins have had a disastrous effect on the ecological balance of plants, animals, and even microbes. On the basis of nanotechnology, several methods for decontaminating water that use nanoadsorbents and/or photocatalysts are being researched. Due to their improved physical and chemical characteristics, several research studies have focused on the elimination of organic and inorganic pollutants using ferritesupported nanocomposite polymers as possible affordable substitutes for currently employed materials. In this review, the toxicity of heavy metals and the different adsorption capabilities of metal-doped ferrites, which are employed to detect the pollutants in wastewater, are discussed in detail. Also, it provides various synthesis methods to produce ferrite-supported polymer-based nanocomposites and a current review of them with a special emphasis on their exceptional ability to remove organic and inorganic pollutants from wastewater. As a result, ferrite-supported polymer-based nanocomposites, which are also less expensive and swellable, can act as effective adsorbents for the removal of both organic and inorganic pollutants. It has outstanding performance for sizes between 10 and 30 nm.

“…In 1992, Kresge and Beck et al from Mobil successfully synthesized M41S silica (aluminum)-based ordered mesoporous materials with adjustable pore sizes ranging from 1.5 to 10 nm using cationic surfactants as template agents, thus extending the pore size of porous materials from the microporous to the mesoporous range . Mesoporous materials have characteristics such as large inclusions, large specific surface area, easy modification of internal and external surfaces, orderly pore channels, adjustable pore size, high porosity, high permeability, nontoxicity, good biocompatibility, and high thermodynamic stability. − Among its many applications are catalysis, adsorption, separation, energy storage, and drug delivery. ,− There has been significant progress in the development of mesoporous materials, which have now become a hot research topic. − …”

The world today is witnessing a new technological revolution, particularly in the area of new materials. Different types of materials often have different characteristics and uses. Mesoporous materials have a large specific surface area, easily modifiable inner and outer surfaces, tunable pore size and pore channels, and good biocompatibility and thermodynamic stability, thus emerging as a new candidate material in the chemical research community. The presence of mesopores facilitates the rapid diffusion of macromolecules, reduces resistance to mass transfer, and provides different properties depending on the pore size, making mesoporous materials a potential candidate for a wide range of applications. This paper reviews the recent methods used to synthesize mesoporous materials, including hydrothermal synthesis, microwave synthesis, the sol−gel method, the phase conversion method, and the templating method. The soft templating method is introduced in detail, including bulk self-assembly, solvent evaporation-induced self-assembly, solution-based nanoprecipitation, interfacial self-assembly in a solution, and emulsion template self-assembly. The current status of the processes related to mesoporous materials in the fields of biomedicine, environmental and energy, electrochemical energy storage, and gas separation is elaborated. Finally, the technical issues and future directions in the synthesis and application of mesoporous materials are briefly discussed.
