“…The hydrogels prepared through the interaction between a specific form or electromagnetic radiation and polymers or monomers have vast fields of app Based on the radiation method used, the hydrogels can be classified as shown in The radiation method proceeds through the formation of free radicals from solvents (H 2 O), polymer backbones, and monomers. The effect of radiation on raw materials is dependent on the energy and frequency range of the applied dose, as well as the types of polymers, solvents, and monomers [47,48]. We choose the radiation based on the criteria that the hydrogels must meet; for instance, we synthesize highly pure hyaluronic acid/chondroitin sulfate-based hydrogels for biomedical applications using gamma radiation [9].…”

Along with serving as drug delivery sensors and flexible devices, hydrogels are playing pioneering roles in water purification. Both chemical and radiation methods can produce hydrogels, with the latter method gaining preference for its pure adducts. The water treatment process entails the removal of heavy and toxic metals (above the threshold amount), dyes, and solid wastes from industrial effluents, seawater, and groundwater, as well as sterilization for microorganism destruction. This review analyzed the different types of hydrogels produced by applying various radiations for water treatment. Particularly, we examined the hydrogels created through the application of varying levels of gamma and electron beam radiation from the electron gun and Co-60 sources. Moreover, we discuss the optimized radiation doses, the compositions (monomers and polymers) of raw materials required for hydrogel preparation, and their performance in water purification. We present and predict the current state and future possibilities of radiation-induced hydrogels. We explain and compare the superiority of one radiation method over other radiation methods (UV-visible, X-ray, microwave, etc.) based on water treatment.

In recent years, waste storage and recycling have been important issues. All efforts shown in these fields aim to help resolve concerns related to climate change. In this study, recycled CF/PEKK thermoplastic composite materials were reviewed to reduce the environmental impact of materials during the production phase as well as economic costs and ensure product continuity. Comparisons between unprocessed or virgin material and recycled materials were performed by bending and interlaminar shear strength (ILSS) analyses. In addition to mechanical tests, physicochemical tests such as differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and fiber void ratio (FVC)-porosity tests were conducted. Images of the samples were observed by scanning electron microscopy (SEM) to interpret changes in the structure before and after the recycling. According to the experimental results, it was found that the virgin thermoplastic composite showed 68.05% higher flexural strength and 7.85% higher flexural modulus compared to the recycled thermoplastic composites. The average ILSSs were measured as 81.8 MPa and 64.7 MPa for the virgin and the recycled thermoplastic composites, respectively. Hence, it is obvious that the recycled composites could be used for applications that require less strength and durability. Finally, it was concluded that recyclable materials can be reused in the aero structures.

A favorable candidate for innovative feed supplement ingredients that can optimize nutrient utilization and reduce environmental impacts could be a slow-release urea based on irradiated chitosan. Chitosan, a biopolymer derived from chitin, has shown immense potential in various applications due to its unique physicochemical properties and biocompatibility. The findings of this study shed light on the promising prospects of irradiated chitosan as a feed supplement ingredient for slow-release urea formulations. Slow-release gel is composed by starch, acrylamide, polyvinyl alcohol and irradiated chitosan. Copolymer gels are treated by Co-60 gamma-ray with 5 kGy and 10 kGy absorbed doses. The lowest gel viscosity escalation is around four thousand times and the highest is more than seventy thousand times. As time of immersion and acrylamide raise in per vary from dose absorbed, gel swelling capacity also increases, start from 33.13 g/g at 5 minutes rise to 164.71 g/g at 720 minutes. Gel fraction from 5 kGy nearly increases two times from 53.57 g/g to 125 g/g at 10 kGy.
