“…The combination of ELT and biological treatment (SI, section S1) is one of the highly effective technological methods. ,,− ,,,,− In particular, such a combination was implemented at the Voronezh Synthetic Rubber Plant for the degradation of biologically stable Nekal, a mixture of isobutylnaphthalenesulfonates. , Irradiation with electrons at doses of 2–3 kGy leads to the elimination of the alkyl and sulfonate groups; as a result of this, necal is converted into biodegradable products. The bubbling of wastewater by the air–ozone mixture formed in the air gap between the accelerator and the stream of treated water contributes to this conversion of Nekal.…”

During the prebiotic era, radiolytic transformations in the oceans played a key role in purifying water from toxic impurities and, thus, played a role in the formation of the aquatic environment of our planet, making it suitable for the emergence of life. Today, the planet again faces the challenge of how to provide people with clean water. Therefore, it is reasonable to look back at past historical stages and again consider the possibility of neutralizing pollutants in water by means of radiolysis, which has already been tested by time. Modern radiolytic treatments can be much faster and safer thanks to the advent of powerful electron accelerators and high-rate electron beam treatment (ELT) of water and wastewater. Radiolytic treatment of water using accelerated electrons corresponds to the essence of advanced oxidative technologies and green chemistry. The ELT of water instantly generates a high concentration of short-lived radicals that can quickly neutralize and decompose chemical and bacterial pollutants. Due to the ability of accelerated electrons to penetrate into a substance, ELT provides the decomposition of both dissolved and suspended pollutants. The cleaning effect of ELT is due to the ability to inactivate toxic and chromophore functional groups, transform impurities into an easily removable form, damage the DNA of microorganisms and their spore forms, and increase the biodegradability of organic impurities. The use of ELT in water treatment provides significant savings in chemical reagents, thereby improving quality and reducing the number of cleaning steps. The compactness, high degree of automation of the equipment used, energy efficiency, high productivity, and excellent compatibility with traditional water treatment methods are important advantages of ELT. Unlike conventional chemicals, the excess radicals generated in the ELT process are converted back to water and hydrogen; thus, the chemical and corrosive activity of water does not increase. Equipping research institutes with electron accelerators, developing cheaper accelerators, and granting government support for pilot projects are key conditions for introducing ELT into water treatment practice.

“…It is a fast process and the reaction is easily controlled by adjusting the dose rate. 16 Therefore, EB irradiation polymerization to prepare LCEs might be seen as a very simple process, which just needs irradiating of a suitably aligned mixture of liquid crystal monomer and crosslinker.…”

Oriented side chain liquid crystal elastomer (LCE) films with thermo-and photo-mechanical properties were prepared via electron beam (EB) irradiation. A magnetic field was applied to the nematic monomers during the polymerization to obtain aligned LCEs. The effects of the crosslinker concentration in feed, delivered dose and direction of the magnetic field during the polymerization on the properties of the LCEs were studied, respectively.
