“…Radiation technology has been proved useful in nanotechnology as it has been explored mainly using high-energy charged particles, e.g., electrons and ions, as well as photons such as X-ray and gamma rays [ 7 ]. Some non-ionizing sources of radiation such as microwave and ultraviolet (UV) light under specific wavelengths may also be applied.…”

At a nano-level, optical properties of gold are unique and gave birth to an emerging platform of nanogold-based systems for diverse applications, because gold nanoparticle properties are tunable as a function of size and shape. Within the available techniques for the synthesis of gold nanoparticles, the radiolytic synthesis allows proper control of the nucleation process without the need for reducing agents, in a single step, combined or not with simultaneous sterilization. This review details and summarizes the use of radiation technologies for the synthesis and preparation of gold nanoparticles concerning fundamental aspects, mechanism, current pathways for synthesis and radiation sources, as well as briefly outlines final applications and some toxicity aspects related to nanogold-based systems.

“…In recent years, the use of ionizing radiation to enhance the structure and properties of nanoscale structures has become one of the promising areas of modern materials science [1]. In addition to the large-scale application in the synthesis of nanoscale structures [2,3], the use of microwave [4], X-ray [5] and gamma radiation [6,7], as well as the processing by accelerated electron beams [8,9] and ions [10] allows directed modification of both the crystal structure and the functional properties of nanomaterials.…”

This study considers the effect of various doses of electron irradiation on the crystal structure and properties of composite catalysts based on polyethylene terephthalate track-etched membranes and copper nanotubes. Copper nanotubes were obtained by electroless template synthesis and irradiated with electrons with 3.8 MeV energy in the dose range of 100–250 kGy in increments of 50 kGy. The original and irradiated samples of composites were investigated by X-ray diffraction technique (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The improved catalytic activity of composite membranes with copper nanotubes was demonstrated by the example of the reduction reaction of p-nitrophenol in the presence of sodium borohydride. Irradiation with electrons at doses of 100 and 150 kGy led to reaction rate constant increases by 35 and 59%, respectively, compared to the non-irradiated sample. This enhancing catalytic activity could be attributed to the changing of the crystallite size of copper, as well as the surface roughness of the composite membrane.

“…In our first submission, we stated with un-irradiated and γ-irradiated indium acetate with 10 2 kGy γ-ray absorbed dose as precursors for preparation of In 2 O 3 nanoparticles by sol-gel methods. The results demonstrated different morphologies and particle sizes for the as-synthesized In 2 O 3 nanoparticles as result of γ-irradiation 14 .…”
