“…The e-beam kind of processing is a method employed in modifying the properties of the polymer (plastic) surface with lowenergy electrons utilised in crosslinking, modifying or improving adhesion to the surfaces. If polymers are treated with the e-beam irradiation, no additives are needed and no hazardous chemical bi-product are emitted [30]. In recent decades, there has been a steady increase in treatment of polymers through gamma radiation, because of, the polymer materials are modified and improved with respect to their chemical, physical, electrical, structural and optical properties [31].…”

In recent decades, researchers have used plastic to replace natural aggregates (NAs), or as filler and fibre within the concrete. This particular paper puts forward a review that gives comprehensive consideration to the properties and drawbacks, of concrete that contains plastic. As such, it may be hypothesised that poor bond capacity and higher air content due to inclusion of plastic aggregate (PA) within concrete are the predominant factors that reduce the properties in terms of mechanics and durability. In that regard, this study has put forward a new method of curing using microwave irradiation for improvement with respect to those factors. So, that there can be further improvement with regard to overall durability with respect to advanced chemical and hydrophobic resistivity and enhanced performance for conventional concrete with respect to bonding and ductility.

“…The radiation grafting method consists of the step of irradiating the desired polymer to generate radicals in the main and side chains of the polymer and the step of mixing the polymer in which the radical is formed with other monomers to form a graft polymer. When these steps are done separately, it is referred to as the pre-irradiation method and when the polymer and monomers mixture is carried out, it is called the simultaneous-irradiation method [ 27 , 28 , 29 ]. In our previous studies, novel double-layered cation exchange membranes were prepared by simultaneous electron beam irradiation and were successfully applied to the saline water electrolysis (SWE) single cells [ 30 , 31 ].…”

In this research, a series of innovative and stable cross-linked gel polymer reinforced membranes (GPRMs), were successfully prepared and investigated for application in lithium-ion batteries. Herein, a gel directly within the commercial polyethylene (PE) separator is supported via electron-beam simultaneous irradiation cross-linking of commercial liquid electrolyte and poly(ethylene glycol) methacrylate (PEGMA) oligomers. The physical and electrochemical properties of the GPRMs were characterized by SEM, TEM, mechanical durability, heating shrinkage, and ion conductivity, etc. The GPRMs demonstrated excellent mechanical durability and high ion conductivity compared with traditional PE membranes. Moreover, coin-typed cells were assembled and cycle performance was also studied compared with same-typed cells with commercial PE membrane and liquid electrolyte. As a result, the coin-typed cells using GPRMs also showed a relatively good efficiency on the 50th cycles at a high 1.0 C -rate. These GPRMs with excellent properties present a very promising material for utilization in high-performance lithium-ion batteries with improved safety and reliability.

“…For the sterilization of medical devices, gamma radiation is mainly used in the world. However, recently, the use of electron accelerators for these purposes is gaining popularity [4,5]. So, for example, in Russia, unlike other countries, there are more installations with electron accelerators than gamma installations.…”

Radiation sterilization is widely used to sterilize nonwoven SMS medical products. SMS materials have improved filtering and barrier properties, low bacteriopermeability and, due to these properties, are indispensable for medicine. They are used to make such important health care products as disposable surgical clothing and underwear. As a result of the research carried out, the effect of gamma and electron radiation, in the range of absorbed doses from 15 to 25 kGy, on the strength characteristics of nonwoven SMS materials based on polypropylene with a surface density of 35, 40, 50 g/cm2 was studied. It has been established that the strength characteristics (tensile strength, tensile strength, and tear strength) of nonwoven materials decrease after exposure to ionizing radiation. The higher the density of the material, the more its characteristics decrease after radiation sterilization. It was also found that gamma radiation, due to its nature, has a stronger effect on nonwoven materials based on polypropylene, and leads to a stronger decrease in strength characteristics. In general, for products sterilized by ionizing radiation and made from SMS materials, it is important to control the strength characteristics, primarily, the tensile strength in the transverse direction of the web stuff.
